Strings, Pheno and the Swampland (SPS) Journal Club Title: Sharpened Dynamical Cobordism Speaker: Alejandro Javier Puga Gómez (IFT)  Venue&Time: Red Room / 12:00   Abstract: We propose a sharpened version of Dynamical Cobordism, where the physical structure ξ of the theory in question determines an allowed range Rξ for the critical exponent δ. We interpret a singularity with δ∈Rξ as a true transition-to-nothing, […]

Every Thursday at 12:00 in Grey Room 2.

Valeria Costa (IFT) will present: Cosmological Lower Bound on Heavy-Neutrino Masses, de B. W. Lee y S. Weinberg. Venue&Time: Blue Room / 17:00 Abstract: The present cosmic mass density of possible-stable neutral heavy leptons is calculated in a standard cosmological model. In order for this density not to exceed the upper limit of 2*10^-29 g/cm^3, […]

Title: 'Onset of Ergodicity Across Scales on a Digital Quantum Processor' Speaker: Marcos Crichigno (Phasecraft) Venue & Time: Gray Room 3 / 11:30 Abstract: Boltzmann’s ergodic hypothesis lies at the foundation of classical statistical mechanics, yet its quantum counterpart remains far less understood. In this talk, I will discuss a quantum-information-theoretic measure of quantum ergodicity […]

Title: 'Exponential quantum advantage in processing massive classical data' Venue/Time: 11:30 / Gray Room 1 Speaker:  Isabel María Moreno Cuadrado (ICMAT) will present 'Exponential quantum advantage in processing massive classical data' by Hsin-Yuan Huang et al. Abstract: Broadly applicable quantum advantage, particularly in classical data processing and machine learning, has been a fundamental open problem. […]

Title: Boundary entropy and entanglement phase transitions in holographic ICFTs Speaker: Evangelos Afxonidis (University of Oviedo) Venue&Time: 11:30 / Gray Room 3 Abstract: In 1+1 dimensional conformal field theory with a boundary, the boundary contribution to the entanglement entropy is encoded in a single number g, effectively counting the boundary degrees of freedom. In contrast, […]

Every Tuesday at 2:00 PM in the discussion room on the 5th floor. Join the IFT cosmology/gravity journal club at benty-fields.com to vote for papers and volunteer to present them

Title: Bubble Nucleation from Boson Star Collapse Speaker: Kateryna Radchenko Serdula (IFT) will present "Bubble Nucleation from Boson Star Collapse", 2511.21826 Venue&Time: Gray Room 2 / 12:00 Abstract: We present a new classical mechanism for nucleation of bubbles of true vacuum. The mechanism arises when dense boson stars form in the false vacuum. As the […]
