SUMMARY:DIFT Colloquium by Izaskun Jimenez-Serra:  Towards prebiotic chemistry in the interstellar medium
DESCRIPTION:Date and time: 15:30h (CEST)\, Thursday\, 8 October 2026 \nLocation: CFTMAT Auditorium \nSpeaker: Izaskun Jimenez-Serra \nTitle: Towards prebiotic chemistry in the interstellar medium \nAbstract: In the past decade\, Astrochemistry has witnessed an impressive increase in the number of detections of new molecular species in space. The majority of these detections are related to complex organic molecules (or COMs)\, defined as carbon-based compounds with more than five atoms in their molecular structure.\nInterestingly\, some of these complex organics are of prebiotic interest and\, hence\, they are believed to be involved in the first biochemical processes that led to life.\nRecently\, we have obtained ultra-sensitive\, broadband spectral surveys toward the G+0.693 molecular cloud\, located in the Galactic Center and known to be one of the richest chemical repositories of the Milky Way.\nOur spectral surveys\, carried out with the Yebes 40m and IRAM 30m telescopes\, have allowed us to detect nearly 30 new molecular species\, which include precursors of ribonucleotides\, nucleobases\, amino acids\, sugars\, proto-proteins and proto-lipids\, as proposed in theories of the origin of life.\nIn this talk\, I will present all these findings and analyze how chemical complexity builds up in the interstellar medium\, not only in the extreme environment of the Galactic Center\, but also during the initial conditions of Solar-system formation. \nZoom link to follow the colloquium live: https://us02web.zoom.us/j/83905016433?pwd=4HyoWxuBRD1m8b9FvhMlS2bF68ZV0M.1 \nMeeting ID: 839 0501 6433 \nPasscode: 538063

SUMMARY:Holo-Club: Lanczos Meets Orthogonal Polynomials
DESCRIPTION:Title: Lanczos Meets Orthogonal Polynomials \nSpeaker: Le-Chen Qu \nVenue & Time: 11:30 / Red Room \nAbstract: In this talk\, I will explain the connection between the Lanczos algorithm and orthogonal polynomials and its application to spread complexity in large-$N$ random matrix models. The three-term recurrence relation for orthogonal polynomials has the same structure as the Lanczos recursion\, allowing the polynomial recursion coefficients to be identified with the Lanczos coefficients. For an infinite-temperature thermofield double state\, equations for these coefficients follow from the Coulomb-gas equation. In one-cut matrix models\, the Lanczos coefficients approach constants at large Krylov index\, leading to linear growth of spread complexity at late times. A Bloch-wave analysis expresses the asymptotic growth rate as a spectral average of the group velocity. For even potentials\, differences between consecutive squared Lanczos coefficients also admit a geometric interpretation as generating functions for planar maps whose marked legs are separated by a fixed geodesic distance. Quartic matrix models and the double-scaled SYK model illustrate these results. The talk concludes with the large-index asymptotics of recursion coefficients for general polynomial potentials and the gradient catastrophe that appears in the continuum limit of asymmetric models. \n

SUMMARY:IFT Colloquium by Mark Srednicki (UC Santa Barbara): "Quantum chaos and the foundations of statistical mechanics"
DESCRIPTION:Coffee: 11:00 / Ground-floor cafeteria \nDate and time: 11:30h\, Wednesday\, 14 October 2026 \nLocation: Blue Room \nSpeaker: Mark Srednicki\, University of California\, Santa Barbara \nTitle: “Quantum chaos and the foundations of statistical mechanics” \nAbstract: Understanding the emergence of the rules of statistical mechanics for an isolated many-body system from an underlying quantum-mechanical microdynamics is a longstanding problem of\nfundamental physics. Concepts from the theory of quantized classically chaotic systems can be used to resolve at least some of the key issues\, and lead to the notion of “eigenstate\nthermalization”: individual energy eigenstates of the system as a whole appear to be states of thermal equilibrium when probed by local (few-body) observables.

SUMMARY:Seminar by Lina Castiblanco: "Forecasting cosmological constraints beyond two-point statistics with One-Point Statistics "
DESCRIPTION:Title: Forecasting cosmological constraints beyond two-point statistics with One-Point Statistics \nSpeaker: Lina Castiblanco \nBio: I am a cosmologist and postdoctoral researcher at Bielefeld University. My research focuses on extracting information about the large-scale structure of the Universe beyond traditional two-point statistics\, particularly through one-point probability distribution functions of weak lensing and galaxy clustering. During my PhD at Pontificia Universidad Católica de Valparaíso\, I worked on modelling the galaxy bispectrum and topological statistics to constrain primordial non-Gaussianity. \nVenue & Time: Blue Room | 11:00 \nAbstract: Current and next-generation galaxy surveys will provide vast datasets to improve our understanding of the Universe\, once we extract their maximum information content. However\, the late-time matter distribution is non-Gaussian\, limiting the information captured by two-point statistics. To fully exploit the cosmological signal\, it is essential to incorporate beyond-two-point statistics\, such as one-point probability distribution functions (PDFs)\, which capture key non-Gaussian information from both galaxy clustering and weak lensing. In particular\, the weak lensing convergence PDF is sensitive to the physics of the dark Universe\, including dark matter and dark energy. This information is extracted more efficiently by performing a tomographic analysis. Additionally\, a combined analysis of galaxy clustering and weak lensing in a joint PDF offers a powerful way to jointly constrain cosmology and galaxy bias. We also need to consider systematic effects\, such as shape noise\, intrinsic alignments\, photometric redshift errors\, and mass-mapping\, which can lead to biased cosmological parameter estimates if they are neglected or not properly modelled. In the talk\, I will present our theoretical modelling of the tomographic convergence PDF and the joint weak lensing–galaxy clustering PDF\, including these systematic effects\, and show our analyses combining the PDF with standard 2-point correlation functions\, which show that the PDF is a powerful statistic for extracting non-Gaussian information.

SUMMARY:Quantum Info JC: Joint quantum measurements on distant physical systems
DESCRIPTION:Title: Joint quantum measurements on distant physical systems \nVenue & Time: 11:30 / Gray Room 3 \nAbstract: Joint measurements are pivotal in quantum theory\, featuring prominently in key quantum information primitives such as entanglement swapping\, teleportation\, and dense coding. A historically important question has been whether joint measurements can be performed at a distance\, without bringing together the particles to be measured. The original motivation for asking this was understanding whether the measurement process in quantum mechanics is compatible with relativity\, which was already put into question by Landau and Peierls in 1933. However\, its interest is not only fundamental\, since being able to perform joint measurements locally will have a strong impact in the development of protocols for quantum communication and distributed quantum computing. \nIn this talk I will describe a protocol for performing any joint quantum measurement on distant physical systems. It consists on multiple rounds of blind teleportation\, and thus requires of pre-shared entanglement. The amount of rounds needed for localizing a given measurement can be understood as a measure of its complexity. Thus\, we give the first complete classification of joint quantum measurements. I will show that many of the joint measurements that are now routinely studied theoretically and implemented experimentally have low complexity according to this measure. This indicates that there are still many interesting phenomena to discover when it comes to joint quantum measurements.

SUMMARY:SPS Journal Club: "The Gravitational Path Integral and Initial Conditions of the Universe" by Luis Zapata
DESCRIPTION:Strings\, Pheno and the Swampland (SPS) Journal Club. Every Thursday at 12:00 in the Red Room. \n  \nVenue&Time: Red Room / 12:00 \n Speaker: Luis Zapata \nTitle: “The Gravitational Path Integral and Initial Conditions of the Universe” \nAbstract: Tracing the cosmic evolution of the universe backward leads to a regime where any classical and effective description of spacetime and matter is expected to break down. Understanding those initial conditions raises the question whether a UV complete theory of Quantum Gravity can provide a consistent framework describing its initial stages. Despite the significant progress in UV-complete approaches such as String Theory\, a fully satisfactory answer accounting for these cosmological initial conditions remains open. \nIn this talk\, we will explore a bottom-up approach to this question through the Hartle-Hawking no-boundary proposal introduced in the 1980s. This proposal attempts to define the initial quantum state of the universe through a gravitational path integral over geometries satisfying suitable boundary conditions. We will review the basic ideas\, placing particular emphasis on implications for inflationary initial conditions of our universe.

SUMMARY:DIFT Colloquium by Paolo Dini: Can AI Save or Destroy the Planet? The Sustainability Challenge Behind Artificial Intelligence
DESCRIPTION:Date and time: 15:30h\, Thursday\, 15 October 2026 \nLocation: CFTMAT Auditorium \nSpeaker: Paolo Dini \nAfiliación: Centre Tecnològic de Telecomunicacions de Catalunya (CTTC/CERCA) \nTitle: “Can AI Save or Destroy the Planet? The Sustainability Challenge Behind Artificial Intelligence” \nAbstract: Artificial Intelligence is increasingly being presented as a powerful enabler of sustainability. From climate change mitigation and renewable energy integration to environmental monitoring\, waste management\, water conservation\, disaster response\, and pollution control\, AI offers unprecedented opportunities to support more sustainable and resilient societies. \nHowever\, the rapid expansion of AI also raises critical questions. What are the environmental implications of having virtually unlimited computational power at our disposal? What is the real impact of AI on energy production and consumption? Can the benefits of AI outweigh the growing demand for data centers\, computing infrastructure\, and digital resources? And what technological and organizational foundations are needed to ensure that AI itself remains sustainable? \nThis talk will explore the dual role of AI as both a tool for sustainability and a source of environmental and societal challenges. It will examine the energy\, infrastructure\, and resource requirements behind modern AI systems\, discuss emerging approaches for reducing their environmental footprint\, and reflect on how research\, industry\, and policy can contribute to the development of truly sustainable AI. \nCoffee: 16:30 / Ground-floor cafeteria \nZoom:\nhttps://us02web.zoom.us/j/85894121596?pwd=liPBLJZn1SIwUg3NRBapJ9vWpbCgFv.1 \nMeeting ID: 858 9412 1596\nPasscode: 672626

SUMMARY:Seminar by Mark Srednicki (University of California\, Santa Barbara): "Probability in Quantum Mechanics"
DESCRIPTION:Title: “Probability in Quantum Mechanics”\n \nSpeaker: Mark Srednicki (University of California\, Santa Barbara) \nVenue & Time: Red Room / 15:00 \nAbstract: This year marks the 100th anniversary of the Born rule for probabilities of outcomes of measurements on quantum systems\, but there is still no generally accepted understanding of its status. One reason for this lack of consensus is that there are several inequivalent conceptions of probability itself\, and any proposed derivation of the Born rule depends on which one is adopted. The key question for physics is whether or not a “collapse postulate” is needed\, or whether\, as originally proposed by Everett\, unitary time evolution of a quantum state of the universe is consistent with observation\, including the Born rule. I will argue that it is\, and that the appropriate conception of probability is the original one of Laplace. The “decoherent histories” formalism of Gell-Mann and Hartle provides the necessary mathematical structure.

SUMMARY:Quantum Info JC: "An operational continuum limit of quantum processes"
DESCRIPTION:Title: An operational continuum limit of quantum processes \nVenue & Time: 11:30 / Gray Room 3 \nAbstract: Quantum combs are a powerful tool for investigating quantum processes and their multi-time correlations in quantum information theory. However\, they do not naturally accommodate a physical connection to time\, and their probes are inherently instantaneous\, meaning control strength is not encoded in the theory. \nIn this talk I will present our work which introduces a framework of continuous process tensors (cPTs) for combs in a process context\, remedying this situation. Here\, process tensors are represented by bosonic field theory vectors on the relevant time interval. Associating controls with particle insertions allows us to relate the distinguishing power of instruments with the energetic resources required to implement them. For example\, recovering the discrete case\, instantaneous probes correspond to particle number eigenstates with infinite Fock space norm. As I will elaborate\, this finite-energy perspective also yields well-behaved measures of non-Markovianity\, fixing contradictory properties of standard measures. \nBuilding on this\, we also proved via an explicit dilation theorem that our framework connects to the Schrödinger equation. This gives physical context\, showing that any cPT can be approximated arbitrarily well in Fock space norm by a coupled system-environment dynamics. I will explain in more detail this theorem and show how it enables a set of structural results\, such as Choi duality in the continuum and a rigorous treatment of measurements. \nOur framework thus fills a substantial gap in the quantum information literature by enabling the physically-consistent study of open quantum dynamics and multi-time correlations in the continuum.

SUMMARY:SPS Journal Club: "Journey to the Centre of the Black Hole" by Matthew J. Blacker
DESCRIPTION:Strings\, Pheno and the Swampland (SPS) Journal Club. Every Thursday at 12:00 in the Red Room. \nTitle: “Journey to the Centre of the Black Hole” \nVenue & Time: Red Room / 12:00 \n Speaker: Matthew J. Blacker \nAbstract: What can we say about holographic theories\, given what we know about the bulk? Conversely\, how can we use holographic theories to probe regions of the bulk where classical physics breaks down? This talk will explore the link between bulk canonical quantum gravity and holographic theories\, using radial Wheeler-DeWitt states as the bridge. We will discuss how Wheeler-DeWitt states can be used a) to constrain putative holographic duals to de Sitter space\, and b) to probe the interior of black holes and the (chaotic) approach to the singularity. Finally\, we will explain how these radial states relate to $T^2(+ \Lambda_2)$ deformed field theories.

SUMMARY:Seminar by Bethany Anne Suter (Fermilab and IFT): “Dark matter sensitivity projections for all known inorganic materials”
DESCRIPTION:Title: Dark matter sensitivity projections for all known inorganic materials \nSpeaker: Bethany Anne Suter \nVenue & Time: Red Room / 15:00 \nAbstract: In this talk\, I will discuss my work on performing the highest-throughput search and evaluation of inorganic materials that can serve as excellent low-mass dark matter detectors. We use a graph neural network (GNN) based on the GNNOpt architecture to learn and generate dielectric tensors\, loss functions and sensitivity curves for both isotropic and anisotropic materials. Since the only required input for this GNN model is the structure of the unit cell\, this analysis can now be expanded to any known inorganic material\, increasing the number of materials analyzed by over 2 orders of magnitude. We apply this model to all materials available on the Materials Project database and show the results for absorption and scattering between dark matter and electrons. We also extend the GNN to predict anisotropy in the materials and calculate daily modulation in the interaction rates\, which enables sensitivity to the dark matter wind. The training dataset is derived from nearly one thousand DFT-calculated dielectric tensors taken from Materials Project as well as previously calculated loss functions and sensitivity curves. The GNN predicts the output to percent level accuracy with no prior knowledge of DFT and the output obeys the Kramers-Kronig relations and physical sum rules similarly to the original dataset.

SUMMARY:Old Journal Club: “Distortions of the Background Radiation Spectrum”
DESCRIPTION:Title: Distortions of the Background Radiation Spectrum \nSpeaker: Mikel Martin Barandiaran \nVenue & Time: Blue Room / 17:00 \nAbstract: The discovery of cosmic blackbody radiation with a temperature of 2.7 K is widely considered as powerful evidence for the hot\, big-bang model of the universe. As first discussed by Gamow\, it is assumed that a very hot\, dense plasma was present during the early stages of the universe\, and interaction of photons and electrons leads inevitably to an equilibrium (blackbody) spectrum. The shape of the equilibrium spectrum is preserved during the subsequent expansion and cooling\, although the radiation temperature decreases to the value of 2.7 K observed today.

SUMMARY:Seminar by Eduardo Peinado (Mexico U.): "Three jobs for a U(1): dark matter stability\, light portals\, and neutrino and Higgs masses"
DESCRIPTION:Title: “Three jobs for a U(1): dark matter stability\, light portals\, and neutrino and Higgs masses” \nSpeaker: Eduardo Peinado (Mexico U.) \nVenue & Time: Red Room / 15:00 \nAbstract: Adding a U(1) gauge symmetry is a simple yet surprisingly versatile extension of the Standard Model. In this talk\, I will discuss three roles it can play: stabilizing a dark matter candidate while generating neutrino masses\, opening light portals to new physics that can be probed by low-energy experiments and IceCube\, and\, through the heavy neutrinos of a low-scale seesaw\, setting an upper bound on the Higgs mass.

SUMMARY:Seminar by Mario Reig (CERN): "Testing the Heterotic String and F-theory GUTs with Axions"
DESCRIPTION:Title: Testing the Heterotic String and F-theory GUTs with Axions \nSpeaker: Mario Reig (CERN) \nVenue & Time: Red Room / 15:00 \nAbstract: The topological nature of axion couplings to gauge bosons offers unique opportunities to obtain information about the UV limit of the SM. I will discuss why the discovery of an axion-like particle above the QCD line would rule out Grand Unified Theories\, both in 4 dimensions and in higher-dimensions\, and the perturbative Heterotic String. Based on 2206.07053\, 2410.03820\, 2509.08042\, and 2606.09982.

SUMMARY:SPS Journal Club: “Applications of categorical symmetries in two dimensions”
DESCRIPTION:Strings\, Pheno and the Swampland (SPS) Journal Club. Every Thursday at 12:00 in the Red Room. \nTitle: “Applications of categorical symmetries in two dimensions” \nVenue & Time: Red Room / 12:00 \n Speaker: \nAbstract: The goal of this talk is to give a quick overview of some of my recent work during the last years. I will begin with a lightning review of what generalised symmetries are and why it might be sensible\nto relax the group multiplication structure. I will then discuss two applications: \n1) In Non Linear Sigma Models\, the presence of such symmetries protects some of the coupling constants from receiving any quantum corrections. From a target space point of view\, this means some of the parameters of the background cannot receive \alpha’ corrections. \n2) In systems of free chiral fermions\, they give rise to the phenomenon of ‘twisted scattering’ (an incoming local operator that gets scattered into a point operator attached to a topological line)\, which help explain some long standing puzzles of the fermion-monopole scattering problem.

SUMMARY:Seminar by E. Dimastrogiovanni: "Probing the Early Universe with Gravitational Wave Anisotropies"
DESCRIPTION:Title: “Probing the Early Universe with Gravitational Wave Anisotropies” \nSpeaker: E. Dimastrogiovanni (Groningen) \nVenue & Time: Red Room / 15:00 \nAbstract: Gravitational-wave astronomy is opening a new window onto the Universe. Beyond the signals from individual events\, such as merging black holes\, we are beginning to uncover a background of gravitational waves that may carry traces of the very early Universe. Many different processes can contribute to this background\, so how can we distinguish between them? Looking only at its strength and frequency dependence may not be enough. In this talk\, I will explore another possibility: investigating the small variations in the gravitational-wave signal across the sky. These anisotropies may help us identify its origins and become a powerful new probe of inflation. I will then discuss how combining the gravitational-wave sky with the cosmic microwave background can help us search for primordial signals that might otherwise remain hidden.

SUMMARY:Old Journal Club by Michelangelo Tartaglia: "Quantized Hall conductivity in two-dimensions"
DESCRIPTION:Title: “Quantized Hall conductivity in two-dimensions” \nSpeaker: Michelangelo Tartaglia \nVenue & Time: Blue Room / 17:00 \nAbstract: It is shown that the quantization of the Hall conductivity of two-dimensional metals which has been observed recently by Klitzing\, Dorda\, and Pepper and by Tsui and Gossard is a consequence of gauge invariance and the existence of a mobility gap. Edge effects are shown to have no influence on the accuracy of quantization. An estimate of the error based on thermal activation of carriers to the mobility edge is suggested.\n \nPodeis encontrar toda la info en: https://inspirehep.net/literature/175567
