SUMMARY:PhD Defense by Marienza Caldarola: 'Unveiling the Universe with Gravitational Waves: a Machine Learning approach'
DESCRIPTION:Title: Unveiling the Universe with Gravitational Waves: a Machine Learning approach\n\nVenue & Time: Blue Room / 10:30\n\nAbstract: This thesis is devoted to the study of gravitational waves\, combining theoretical investigations with novel applications of machine learning. The first part of the work addresses the dynamics of hyperbolic encounters\, a class of transient gravitational wave signals. By incorporating orbit precession and post-Newtonian corrections\, this study provides theoretical insights into the emission properties.\nThe second part shifts toward data-driven approaches\, exploring the use of advanced machine learning methods in gravitational waves field. Two main applications are considered: constraining the energy density of the stochastic gravitational wave background through astrometric measurements and inferring the properties of lensed gravitational wave signals. In both cases\, the machine learning frameworks developed here show significant gains in computational efficiency\, with particular promise for real-time signal analysis and alerts\, demonstrating the transformative role of machine learning in enhancing current and future gravitational wave data analysis strategies.\n\nSupervisors: Savvas Nesseris and Sachiko Kuroyanagi

SUMMARY:3rd EDI Training: Gender Perspective in Science
DESCRIPTION:3rd EDI Training – IFT Equity\, Diversity and Inclusion Comitee Training Series \nSpeaker: Alejandra Gámez Abascal\, researcher at the CBM. Chair of CBM Equality Committee. Member of Instituto Universitario de Estudios de la Mujer (IUEM). \nTítulo: ‘Gender Perspective in Science and Research’ \nVenue&Time: Blue Room / 11:00 \nCoffee: 12:30 at the CFTMAT cafeteria. \nAbstract: \nIn recent years\, integrating a gender perspective into science and research has become a key priority within the European Research Area and international research policies. Beyond promoting equal opportunities\, the gender dimension contributes to improving the quality\, relevance\, and impact of scientific knowledge.\nThis seminar will introduce key concepts and definitions related to gender equality in order to provide a conceptual framework for the main principles guiding gender-sensitive research. \nWe will explore the importance of incorporating gender perspectives at different stages of the research process\, from research design and methodology to the analysis\, interpretation\, and dissemination of results. The seminar will also highlight current European policies and frameworks that promote gender equality in research institutions\, including Gender Equality Plans and the integration of the gender dimension in research proposals\, with the aim of supporting researchers in integrating gender perspectives into their scientific work. \n  \nThis seminar aligns with the objectives of the scientific outreach and culture component outlined in the Severo Ochoa project (CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033). In addition to scientific excellence\, this project highlights the center’s commitment to a strong program of training and outreach activities with high social impact. In this context\, organizing training activities on equality\, diversity\, and inclusion helps to reinforce the role of the IFT as an institution committed to social responsibility and the continuous improvement of the scientific environment. This seminar provides tools to analyze the structural barriers present in the scientific field\, particularly in STEM disciplines such as theoretical physics\, aligning with the objectives of attracting and retaining diverse talent that foster an inclusive scientific environment.

SUMMARY:PhD dissertation: 'On String Phenomenology From a Swampland Perspective'
DESCRIPTION:Author: Gonzalo F. Casas\n\n\nTitle: On String Phenomenology From a Swampland Perspective.\n\n\nVenue & Time: Blue Room / 11:00\n\n\nAbstract:  This thesis investigates the deep interplay between particle physics\, cosmology\, and quantum gravity within the framework of string phenomenology. Focusing on Type IIA Calabi–Yau orientifolds with intersecting D6-branes\, we show that the suppression of neutrino masses at infinite-distance limits necessarily entails the emergence of light towers of states. This result establishes a direct link between particle-scale physics and the geometry of extra dimensions\, while also suggesting potentially testable phenomenological signatures. The thesis further connects inflationary dynamics to the quantum-gravity cutoff and examines how supersymmetry breaking in no-scale vacua can give rise to Minkowski backgrounds\, offering a novel perspective on moduli stabilization.\n \nSupervisor: Fernando Marchesano

SUMMARY:2nd EDI Training: 'Beyond law: Invisible Barriers to Women’s Access to Public Life'
DESCRIPTION:Speaker: Soledad Escobar Villegas \nPhD in Political Science and García Pelayo Research Fellow at the Centre for Political and Constitutional Studies\, Ministry of the Presidency (Spain). \nAbstract: Over the last decades\, Western societies has introduced significant legislative changes aimed at promoting gender equality and increasing the representation of women in decision-making positions. However\, legal progress does not always translate into equal participation in practice. \nThis seminar will examine the gender representation gap in politics and society by distinguishing between formal legislative advances and the structural constraints and internal dynamics within political and social environments that continue to limit women’s access to the public sphere. The session will analyze patterns of underrepresentation and explore factors such as unequal career progression\, workplace cultures\, and informal power structures. It adopts an intersectional approach\, considering not only gender but also women’s ethnic and cultural backgrounds. The aim is to encourage students to critically assess how social and institutional systems shape women’s representation. \nThis seminar aligns with the objectives of the scientific outreach and culture component outlined in the Severo Ochoa project (CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033). In addition to scientific excellence\, this project highlights the center’s commitment to a strong program of training and outreach activities with high social impact. In this context\, organizing training activities on equality\, diversity\, and inclusion helps to reinforce the role of the IFT as an institution committed to social responsibility and the continuous improvement of the scientific environment.

SUMMARY:PhD dissertation: 'Shedding light on extended scalar sectors'
DESCRIPTION:By Víctor Enguita \nVenue & Time: Red Room / 12:00 \nAbstract: \nThe Standard Model has a number of traits which are surprising from the theoretical perspective and may hint the presence of some underlying hidden structure beyond the SM. In this thesis\, we explored some of the open problems which materialize from those traits and could be solved by the presence of an extended scalar sector. First\, we considered axion-like particles (ALPs) using an Effective Field Theory (EFT) approach and imposed improved limits on their CP-odd couplings to fermions. The remainder of the thesis was devoted to the Electroweak hierarchy problem (EWHP). We presented two original works which follow two different guiding principles\, one traditional and the other rather innovative: symmetry and near-critical dynamics. The first among these works presents non-abelian discrete symmetries as able to suppress large radiative corrections and stabilize the masses of scalar particles. In the second contribution\, we argue that the small observed mass of the Higgs could be a trademark of the near-criticality of the Higgs sector\, backed by the observation that every parameter in the Higgs potential seems in fact to also be near-critical.  We explore the consequences of this fact using the so-called “Higgs metastability bound” in the case of a concrete model—the low-scale Majoron model—and demonstrate that this justification of the mass of the Higgs implies new experimental signals in future experiments and in particular\, in the future colliders. We argue that this conclusion is actually more general and should apply to wider contexts than the concrete model analysed.\nSupervisors: Belén Gavela & José Miguel No

SUMMARY:Searching for New Physics through the Neutrino (bag)pipe
DESCRIPTION:Daniel Naredo Tuero PhD dissertation \n\nSearching for New Physics through the Neutrino (bag)pipe \n\nVenue&Time: Red Room / 11:00 \n\nAbstract:\nAmong the many open problems that plague the Standard Model (SM) of particle physics\, the massive nature of neutrinos stands out as it is one of the few indications of New Physics that we have observed in our terrestrial laboratories\, as supported by the phenomenon of neutrino flavour oscillations. Neutrinos offer a rich phenomenological and complementary programme\, from laboratory signals to cosmological imprints\, as we will explore in this Thesis. First\, we will assess the status of the cosmological neutrino mass bound in light of the latest results from DESI\, identifying the features and tensions in the data that are driving this ever-tightening constraint. Second\, we will consider the inclusion of heavy Majorana right-handed neutrinos\, the most economical SM extension to generate neutrino masses. In particular\, we will show how it is possible to constrain heavy neutrinos above the electroweak scale by harnessing their effects on precision observables. Lastly\, we will investigate the role of neutrino data in the global fit of the SM Effective Field Theory (SMEFT)\, showing that the inclusion of neutrino oscillation and scattering data can add new valuable information. \nSupervisores: Enrique Fernández-Martínez y Xabier Marcano

SUMMARY:Dragon School: cosmic-ray theory\, phenomenology and beyond
DESCRIPTION:This school is intended to provide an overview about a variety of topic centered around the problem of cosmic-ray transport in the Galaxy and non-thermal diffuse emissions. We will provide both dedicated seminars and hands-on sessions on the modeling and computation of cosmic-ray propagation and the correlated non-thermal emissions in different astrophysical environments. In particular\, the event will feature a detailed presentation of the state-of-the-art theoretical and numerical tools to calculate relevant astro-particle quantities (production of gamma-ray\, radio or neutrino emission\, as well as the signals produced by dark matter)\, especially focused on the broad applicability of the DRAGON2 code. \nThis event will be held at the Institute of Theoretical Physics in Madrid (Spain) from October 8th to October 10th 2025. The organizing committee of the workshop will be composed by the current main developers of the code: Daniele Gaggero (researcher at INFN Pisa)\, Silvio Sergio Cerri (researcher at Lagrange Laboratory – Observatoire Côte d’Azur\, in Nice) and Pedro De la Torre Luque (Juan de la Cierva postdoc at UAM and IFT)\, along with Miguel Ángel Sánchez-Conde (associate professor at UAM and IFT). Event related to the I+D+i project CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033\, and topic framed within the research line Origin and composition of the universe: Astroparticles and Cosmology (Astro/Cosmo). \nThe school will have a duration of three days\, in which the first two days will be dedicated to lectures (during the morning)\, covering cosmic-ray related physics  (astrophysical plasmas\, particle interactions\, computational techniques\, etc) and discussing the status of current observations of Galactic diffuse emissions (radio\, X-ray\, neutrino and gamma-ray diffuse backgrounds) and hands-on sessions (during he afternoon)\, while the third day will be dedicated to a number of invited talks about the use of diffuse emissions for indirect dark matter searches and the DRAGON2 code beyond the study of cosmic-ray propagation. \nSEMINARS: \nMiércoles 08/10/25 a las 15:30h \nSpeaker: Manuel Rocamora \nTitle: “Propagation of cosmic rays and production non-thermal radiations with DRAGON and Hermes” \nAbstract: Cosmic-ray measurements have reached unprecented precision in the last decade. These observations are  challenging our standard intepretation of how cosmic rays generated and how they propagate in the Galaxy. Therefore\, it is crucial to achieve accurate predictions to understand the origin of discrepancies with data. On top of this\, these predictions allow us to infer the non-thermal radiations that cosmic rays produce when they interact with Galactic magnetic fields\, radiation fields and gas. This session is dedicated to provide a detailed overview of the DRAGON and Hermes codes and how they can be used to obtain predictions of the cosmic ray\, gamma-ray\, neutrino and even radio diffuse Galactic fluxes that are correlated. \nJueves 09/10/25 a las 12:45h \nSpeaker: José Alberto Rubiño \nTitulo: Diffuse radio emission \nAbstract: Synchrotron emission from cosmic-ray electrons is a powerful tool for probing both the Galactic magnetic field and the energy spectrum of electrons within our Galaxy. This lecture will cover the fundamental principles of synchrotron radiation\, methods for measuring this emission\, and the current state of observations\, with a focus on measurements in the GHz frequency range.

SUMMARY:PhD dissertation: Quantum Information & its interplay with High-energy Physics
DESCRIPTION:Alexander Bernal (IFT) PhD dissertation. \nSupervisor: Alberto Casas & Jesús Moreno \nVenue&Time: ¨Blue Room / 10:00 AM \nAbstract: \nThis thesis explores the intersection of Quantum Information Theory (QIT) and High-Energy Physics. We demonstrate the presence of entanglement and Bell nonlocality in vector boson systems resulting from scalar and pseudoscalar particle decays\, focusing on the H→ZZ process and generalizing to broader Lorentz-invariant scenarios. We also develop a method for quantum state tomography through angular distributions in scattering processes. Beyond high-energy applications\, the thesis contributes to the field of QIT by providing new tools for studying genuine multipartite entanglement\, exploring CHSH nonlocality violation in hybrid systems\, and introducing operational definitions for fundamental concepts like quantum dimensionality and classicality. These latter results connect with core ideas in QIT such as the accessible information\, the joint measurability\, and the quantum steering.

SUMMARY:PhD dissertation: Advancing Gravitational Wave Data Analysis and  Exploring New Sources
DESCRIPTION:Gonzalo Morrás PhD dissertation.\n\nSupervisor: Juan García-Bellido\n\nVenue&Time: Blue Room / 10:30 AM\n\n\nAbstract: Gravitational wave (GW) astronomy has opened a new window onto the Universe\, allowing us to study compact objects and fundamental physics. This thesis develops new methods and models to improve the detection and interpretation of GW signals\, with a focus on exotic and underexplored sources. It includes pioneering searches for close hyperbolic encounters\, studies of low-mass and sub-solar-mass binaries\, analyses of local cosmic effects on merger rates\, and the development of advanced waveform models and data analysis algorithms. These contributions enhance our ability to uncover new astrophysical phenomena and will support future GW observations with current and next-generation detectors.

SUMMARY:Aspects of inflation beyond the single-field\, slow-roll regime
DESCRIPTION:Speaker: Alejandro Pérez Rodríguez\n\n\nLocation&Place: Red Room\n\n\nAbstract:\n\n\nIn this thesis\, we explore two departures from the single field\, slow-roll paradigm of inflation. The first part is dedicated to warm inflation. We revisit the theory of linear perturbations in this framework\, develop computational techniques for the calculation of the primordial power spectrum and apply them to the analysis of CMB constraints and the production of primordial black holes. The second part focuses on the primordial non-Gaussianity arising from a phase of ultra slow-roll during single field inflation. We study the scope and limitations of the classical delta N formalism as a probe of such non-Gaussianity and determine the extent of its correspondence with the stochastic delta N formalism. \nSupervisor: Guillermo Ballesteros Martínez

SUMMARY:Dynamical Cobordism in String Theory and Holography
DESCRIPTION:Speaker:  Jesús Huertas Castellanos\n\n\nInstitution: IFT UAM/CSIC\n\n\nLocation&Place: Red Room\n\n\nAbstract:\n\n\nThis thesis investigates the intricate relationship between topology\, gravity\, and quantum field theory within String Theory\, centering on the Cobordism Conjecture\, which asserts that any consistent quantum gravity theory must allow spacetime boundaries. It begins by introducing Dynamical Cobordism through models that realize end-of-the-world branes dynamically\, linking them to Swampland constraints. It then explores Bubbles of Nothing as non-perturbative instabilities\, classifying them and analyzing their behavior across various theories. The third section applies Dynamical Cobordism to AdS/CFT\, reinterpreting known duals in type IIB string theory as boundary-terminating geometries. Finally\, it examines topological couplings and anomalies in holographic setups\, introducing the SymTFT framework and uncovering new anomaly inflow mechanisms and Chern-Simons structures. \nSupervisor: Ángel Uranga

SUMMARY:Aspects of symmetries throughout the String Theory Moduli Space
DESCRIPTION:Speaker: Roberta Angius\n\n\nInstitution: IFT UAM/CSIC\n\n\nLocation&Place: Red Room\n\n\nAbstract:\n\n\nThis thesis aims to explore various corners of the string theory moduli spaces using symmetries as a guiding principle to uncover properties of the corresponding theories and their implications for spacetime dynamics.\n\n Within the Swampland Program\, the absence of global symmetries in consistent quantum gravity theories is a key principle\, reformulated in string theory as the Cobordism Conjecture: any consistent configuration must admit spacetime boundaries\, often realized by stringy defects that trivialize cobordism charges. The first part of this thesis implements this idea in effective field theory throughDynamical Cobordism solutions\, where codimension-1 end-of-the-world (ETW) branes appear as finite-distance singularities with scalars diverging to infinite field space. These provide a framework to probe infinite-distance limits in the moduli/field space and Swampland constraints. We construct explicit examples with one or multiple scalars\, including networks of intersecting ETW branes\, and apply them to study infinite-distance singularities in Calabi–Yau fourfold moduli spaces\, described via asymptotic Hodgetheory.\n\nOn the other hand\, we turn to a microscopic approach to string theory and investigate worldsheet generalized symmetries\, defined by topological operators with possibly non-invertible fusion rules. In particular\, we analyze the category of topological defects commuting with spectral flow and N=(4\,4) superconformal symmetry in K3 sigma models. Bystudying their fusion with boundary states\, we argue that while certain models admit infinitely many\, or even continuous families of defects\, at generic points in the K3 moduli space the category is actually trivial.\n\nSupervisor: Ángel Uranga

SUMMARY:On the Asymptotic Global Structure of Duality Frames in Quantum Gravity
DESCRIPTION:Speaker: Ignacio Ruiz García\n\n\nInstitution: IFT UAM/CSIC\n\n\nLocation&Place: Blue Room\n\n\nAbstract:\n\n\nThis thesis studies the global asymptotic structure of moduli spaces in effective field theories compatible with Quantum Gravity\, focusing on the Swampland Distance Conjecture. We develop taxonomy rules that determine the arrangement of towers of light states and duality frames at infinite distance\, showing a finite set of possible global structures. These towers\, interpreted as emergent degrees of freedom\, are linked to the lowering of the EFT cut-off scale\, leading to a universal relation between the leading tower and the cut-off depending only on spacetime dimension. We test these patterns in string and M-theory compactifications\, recovering known constructions and suggesting new landscape corners or Swampland constraints. Finally\, we explore generalizations in lower-supersymmetry settings\, including non-Lorentzian decompactifications\, changing fibration structures\, and additional asymptotic scales\, to better understand the consistency rules for EFTs admitting UV completion to Quantum Gravity.\n\nSupervisor: Irene Valenzuela Agüí

SUMMARY:Exploring infinite distance limits of type II Calabi–Yau compactifications
DESCRIPTION:Speaker: Luca Melotti\n\n\n\nInstitution:  IFT UAM/CSIC\n\n\n\nLocation&Place: Blue Room\n\n\n\nAbstract:\n\n\nThis thesis explores infinite distance limits in the vector multiplet moduli space of type II string theory on Calabi–Yau threefolds. First we classify such limits\, identify the towers of light states\, and test the Emergence Proposal\, which links IR kinetic terms to loop corrections from such states. We then study the scalar curvature of the moduli space along infinite distance trajectories\, focusing on cases where it diverges positively. We argue that such divergences signal decoupled field theory sectors and propose this as the only mechanism for curvature divergences in quantum gravity. Extending the analysis\, we relate these limits to higher-dimensional rigid theories (5d/6d SCFTs and Little String Theories)\, interpreting divergences as a parametric separation between the strength of gravitational and gauge interactions. Finally\, we connect curvature divergences with rigid limits and the existence of BPS states with divergent charge-to-mass ratios. \n\nSupervisor: Fernando Marchesano\n

SUMMARY:Design and Implementation of Quantum Algorithms in the Noisy Intermediate Scale Quantum Era
DESCRIPTION:Abstract:\n\n\nQuantum computing is an emerging paradigm that leverages the principles of quantum mechanics to perform calculations potentially more efficiently than classical computing. It is currently at a crucial stage of its development. Despite its rapid advancement and adoption in both academia and industry\, there are still significant theoretical and practical challenges that must be overcome before quantum computing can materialize on a large scale. An essential step on this path is the identification of problems that are intractable for classical algorithms\, but can be efficiently solved by a quantum computer\, thus demonstrating quantum advantage. Although there are various technologies for the implementation of quantum computers\, all are affected to a greater or lesser extent by the presence of errors in the qubits. Therefore\, it is common to perform a classical post-processing of the results to mitigate these errors. This thesis focuses on the development of quantum algorithms to address problems in fields as varied as Condensed Matter Physics\, Game Theory\, and Quantum Machine Learning. In addition\, advanced error mitigation techniques are presented that allow their implementation on current quantum devices. \nSupervisors: Esperanza López\, Germán Sierra.
