SUMMARY:Holo Club: 'Brick wall Normal Modes and Emerging Thermality'
DESCRIPTION:Speaker: Suman Das (IFT) \nTitle: ‘Brick wall Normal Modes and Emerging Thermality’ \nVenue & Time: Gray Room 1 / 11:00 \nAbstract: \narXiv:2401.01417 \nThe ’t Hooft brick wall model provides one of the earliest microscopic derivations of the black-hole area law within the probe approximation of quantum field theory in curved spacetime. In this talk\, I will revisit the original construction and present a modern perspective based on the spectral properties of the probe fields. After briefly reviewing how the area-proportional entropy arises in ’t Hooft’s setup\, I will show that its origin can be understood in terms of the structure of the normal-mode spectrum. In particular\, a quasi-degenerate growth of states along a specific quantum-number direction leads directly to the area scaling of the entropy.This viewpoint not only clarifies the mechanism behind the entropy but also reveals a number of non-trivial features of the spectrum\, including signatures commonly associated with quantum chaos. I will discuss these features. Finally\, I will show that\, when the brick wall is placed parametrically close to the horizon\, the two-point function of the probe field becomes indistinguishable from a thermal correlator\, providing a precise sense in which thermality emerges in this framework.

SUMMARY:Shannon's Corner Journal Club
DESCRIPTION:Venue & Time: Gray Room 3 / 11:30 \nSpeaker: Franco Salinas Pytel (UCM) \nAbstract: “The debates between Einstein and Bohr on the foundations of quantum\nmechanics culminated in one of the most iconic statements in the\nhistory of physics: “God does not play dice.” \nIn their seminal 1935 paper\, Albert Einstein\, Boris Podolsky\, and\nNathan Rosen argued that if locality is to be maintained\, then quantum\nmechanics must be incomplete. \nIn this talk\, I will present a concise overview of the original EPR\nargument\, Bell’s theorem and its experimental confirmation. I will\nthen explore quantum non-locality through the framework of XOR games\,\nhighlighting their connections to foundational questions in\nmathematics.”

SUMMARY:SPS Journal Club: 'Self-gravitational Effects in the Black Hole-Tower Correspondence'
DESCRIPTION:Strings Pheno and the Swampland Journal Club: ‘Self-gravitational Effects in the Black Hole-Tower Correspondence’ \nVenue&Time: Red Room / 12:00 \nSpeaker: Miquel Aparici (IFT) \nAbstract: It is well-known that in weak coupling and near decompactification limits\, towers of light particles appear in the spectrum of gravitational theories. These towers can be postulated to correspond to minimal black holes in a framework known as the black hole-tower correspondence. We study the transition from towers of particles to black holes and analyze self-gravitational effects of the tower as the EFT cutoff is approached. \n

SUMMARY:SPS Journal Club: 'Quantum Obstructions to N=1 Infinite Distance Limits'
DESCRIPTION:Strings\, Pheno and the Swampland Journal Club \nTitle: ‘Quantum Obstructions to N=1 Infinite Distance Limits’ \nSpeaker: Jeroen Monnee (U. Hamburg) \nVenue&Time: Red Room / 12:00 \nAbstract: We study limits in the field space of 4d N=1 orientifold compactifications of Type IIB string theory with O3/O7-planes that descend from infinite distance limits in the complex structure moduli space of the underlying Calabi-Yau threefold. In particular\, we investigate the fate of such limits in the quantum-corrected field space. We find that such orientifolds can be grouped into two classes\, dubbed O-type A/B\, whose behaviours vary dramatically at the quantum level. For O-type A limits\, we observe that g_s-corrections become unsuppressed by observing that the degeneration of the geometry in the F-theory lift differs drastically from classical expectations. For O-type B limits we instead observe a similar behaviour for alpha’-corrections\, based on the classical inconsistency of EFT string probes combined with explicit computations of such corrections. Based on upcoming work with Lukas Kaufmann\, Timo Weigand\, and Max Wiesner.

SUMMARY:SPS Journal Club: 'Axion-Scalar Systems and Dynamical Distances'
DESCRIPTION:Strings\, Pheno and the Swampland (SPS) Journal Club  \nSpeaker: Gonzalo F. Casas (IFT) \nTitle: ‘Axion-Scalar Systems and Dynamical Distances’ \nAbstract: We study the cosmology of axion-scalar pairs\, coupled by a hyperbolic field-space metric and with a string-motivated rational scalar potential. Borrowing tools from the theory of dynamical systems\, we are able to classify all late-time trajectories and extract physical properties of the asymptotic solutions. These results suggest a Dynamical Distance Conjecture: along the physical (possibly non-geodesic) trajectories\, towers of states become exponentially light as a function of the traversed field-space distance. We further rule out possible counterexamples with wildly oscillating solutions. The considered axion-scalar systems are realized in F-theory compactifications\, where the axion-scalar pair is a complex-structure modulus and four-form fluxes induce the asymptotic potentials. We also provide a complete Hodge-theoretic classification of all one-modulus asymptotic potentials of this type.

SUMMARY:Quantum Information Journal Club: 'Rapid mixing for Gibbs measures in Riemannian manifolds'
DESCRIPTION:Speaker: Pablo Páez-Velasco (Universidad Complutense de Madrid) \nVenue & Time: Gray Room 2 / 14:30 \nAbstract: Given some sufficiently smooth\, generally non-convex\, function F on a Riemannian manifold\, and a fixed inverse temperature\, the problem of sampling with respect to the associated Gibbs distribution has played a central role in several areas\, such as statistical mechanics or non-convex optimization. A natural approach to do so is to simulate the Langevin diffusion associated to F\, whose stationary distribution is precisely the Gibbs distribution. However\, obtaining quantitative convergence guarantees in this non-convex\, geometric setting remains difficult. \nIn this work\, we identify a set of assumptions on F and the underlying manifold under which a log-Sobolev inequality (LSI) holds for the Gibbs distribution in the low-temperature regime. As a consequence\, we obtain exponential convergence of the Langevin diffusion to its stationary distribution.

SUMMARY:Pheno Journal Club: 'Powerful Yukawas'
DESCRIPTION:Every Thursday at 12:00 in Grey Room 2. \nMarta Fuentes (IFT)\, will present “Powerful Yukawas”.\n\nWe introduce a class of models where the masses of the light Standard Model fermions are due to an Effective Field Theory operator that appears beyond dimension-4 in the power counting expansion\, resulting in a `Powerful Yukawa’. The effective Yukawa coupling structure is UV-completed using a collective symmetry breaking pattern in the flavour sector\, which we dub `Sprouted Symmetry Breaking.’ The irreducible signature is an enhanced Higgs coupling to the light Standard Model fermions.

SUMMARY:SPS Journal Club: 'M-theory on S^1 \vee S^1 as Type 0A'
DESCRIPTION:Strings\, Pheno & The Swampland Journal Club | Every Thursday at 12:00 in the Red Room. \nSpeaker: Salvatore Raucci (IFT) \nTitle: ‘M-theory on S^1 \vee S^1 as Type 0A’ \nAbstract: We propose an exotic geometric M-theory dual for the weak coupling Type 0A string: compactification on a sub-Planckian S^1 \vee S^1 (two circles connected at a point)\, where strong quantum effects lead to fields living on distinct resolutions of that space. Moreover we argue that tachyon condensation of the 0A theory corresponds to shrinking of one of the two circles leading to the IIA supersymmetric string. We use this and other dualities to provide an F-theoretic description of the axio-dilaton and the tachyonic field of Type 0B and argue for the existence of a strong coupling critical point of the potential using the resulting duality symmetry Γ_0(2) ⊂ SL(2\,Z). The existence of this critical point can also be argued using conventional M-theory dualities. If this critical point is unique it is an unstable dS vacuum. Using this we propose a strong coupling conformal fixed point for a non-supersymmetric gauge theory in four dimensions living on coincident D3^+ — D3^- branes of 0B.
