Speaker: Julio Navarro Institution: University of Victoria Abstract: Lambda Cold Dark Matter (LCDM) is the most successful theory for the formation of structure in the Universe. Although its predictions have been verified on large scales, they are still contested on the scale of dwarf galaxies, whose dynamical properties are often cited as evidence for the […] |

Speaker: Francesco Gentile Institution: SISSA Location&Place: Grey Room 2 Abstract: In this talk, I will discuss some new interesting properties of geodesic bit threads in static backgrounds. Bit threads are an insightful tool for investigating holographic entanglement entropy, providing a reformulation of the Ryu-Takayanagi formula in terms of the maximal flux of a bounded and […] |

Speaker: Luca Melotti Institution: IFT UAM/CSIC Location&Place: Blue Room Abstract: This 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 […]

Speaker: Ignacio Ruiz García Institution: IFT UAM/CSIC Location&Place: Blue Room Abstract: This 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 […]

The JUNO reactor neutrino experiment has recently begun collecting data, marking the start of a new precision era in neutrino research. With its unparalleled precision, JUNO is poised to refine our understanding of most neutrino oscillation parameters. Its cornerstone measurement - the determination of the neutrino mass ordering -- holds the promise of a breakthrough. […] |

Light Dark World 2025 (LDW'25) is the tenth meeting of the annual Light Dark World International Forum, which will take place between September 16 and September 19, 2025, at the Instituto de Física Teórica (IFT) in Madrid (Spain). The workshop will gather international specialists from both experimental and theoretical backgrounds in order to examine recent […]

Speaker: Roberta Angius Institution: IFT UAM/CSIC Location&Place: Red Room Abstract: This 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. Within the Swampland Program, the absence of global symmetries in consistent quantum gravity […]

Speaker: Jesús Huertas Castellanos Institution: IFT UAM/CSIC Location&Place: Red Room Abstract: This 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 […] |

Speaker: Alejandro Pérez Rodríguez Location&Place: Red Room Abstract: In 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 […] |

Speaker: Mauro Pieroni Institution: IEM-CSIC Location&Place: Red Room Abstract: My talk focuses on using Pulsar Timing Array (PTA) data to measure Gravitational Waves (GWs). In particular, I will focus on Stochastic GW Background (SGWB) measurements. After a general introduction to the topic, I will discuss a new (simplified) approach to constrain SGWBs with PTA data.

Speaker: Alessandro Tomasiello (Milano Bicocca) Venue&Time: 15:00 / Red Room Abstract: Compactifying from higher dimensions typically produces many different vacuum solutions; this leads to multiple possible decay channels, mediated by the nucleation of bubbles. In string theory, the latter can be expanding D-branes. Supersymmetry provides a stabilization mechanism; I will describe how to replicate it […] |

Gonzalo Morrás PhD dissertation. Supervisor: Juan García-Bellido Venue&Time: Blue Room / 10:30 AM Abstract: 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 […]

Quantum Information Journal Club Speaker: Javier Ignacio Lorca Espiro (Universidad de la Frontera, Chile) Venue&Time: Grey Room 3 / 11:30 AM Abstract: Higher dimensional abelian quantum double models have been shown to be well defined in any finite dimension and exhibit the characteristic behavior of SPT phases models. In this talk, we will introduce the […]

Speaker: Bo Wang from Zhejiang U. Inst. Mod. Phys. Venue&Time: Red Room / 3:00 PM Abstract: I will report recent progress on AdS Virasoro-Shapiro and Veneziano amplitudes for half-BPS operators with arbitrary Kaluza-Klein modes. The key ingredient is a bootstrap built directly in the world-sheet representation, together with a novel formalism. This approach yields a […] |

SPS Journal Club Speaker: Bruno De Luca Venue&Time: Red Room / 12:00 Abstract: The problem of constructing de Sitter vacua in quantum theories of gravity is constrained by no-go theorems and made computationally challenging by the absence of supersymmetry. A popular approach to make it more tractableis to start from a supersymmetric compactification, such as […]

Speaker: Go Ogiya from Zhejiang University Venue&Time: Red Room / 3:00 PM Abstract: The origin of the turbulent motion of the intracluster medium (ICM) has been a longstanding open question. Stirring by substructures (member galaxies and dark matter subhaloes) orbiting within a galaxy cluster is a possible mechanism to generate and maintain the ICM turbulence. […] |

Speaker: André Walker-Loud (LBNL) Venue&Time: Red Room / 11:30 AM Abstract: Our ability to understand the emergence of nuclear physics from the Standard Model requires an understanding two nucleon interactions from the underlying quark and gluon degrees of freedom. Due to the non-perturbative nature of QCD at low-energies, the only method to provide such predictions, […]

Speaker: Danilo Artigas Institution: Kyoto University Location&Place: IFT Seminar Room/Red Room Abstract: Linear-perturbation theory has proven to be an extremely powerful tool to compare inflationary models with observational data. Recently, the newcoming high-precision observations call for predictions beyond linear perturbations. Such effects are known to be relevant for example in the production of primordial black […] |

Speaker: Jesús Torrado from IEM-CSIC Venue&Time: Red Room / 3:00 PM Abstract: Inference for slow likelihoods can require weeks or months, if possible at all, with traditional Monte Carlo samplers. This would be the case, for example, when fitting expensive non-linear matter spectrum models, or when characterizing individual long-duration GW events. I will introduce a […] |
