Spin-cobordisms, surgeries and fermionic modular bootstrap
Speaker: Andrea Grigoletto (SISSA & INFN) Title: Spin-cobordisms, surgeries and fermionic modular bootstrap Abstract: ‘tHooft anomalies of anomalous systems can be described via anomaly inflow by invertible theories living in one dimension […]
Black Hole dynamics at Large D
Abstract: I demonstrate that black hole dynamics simplifies – without trivializing – in the limit in which the number of spacetime dimensions D in which the black holes live is taken to infinity. In the strict large D limit and under certain conditions I […]
Sparse Markov Models for High-dimensional Inference
Abstract: Finite order Markov models are theoretically well-studied models for dependent data. Despite their generality, application in empirical work when the order is larger than one is quite rare. Practitioners avoid […]
Quadratic reciprocity from a family of adelic conformal field theories
Member Seminar Speaker:An Huang Title: Quadratic reciprocity from a family of adelic conformal field theories Abstract: This talk aims to provide a physics framework to understand quadratic reciprocity. Specifically, we consider […]
Higgs-Coulomb correspondence in abelian GLSM
Abstract: We construct a certain type of Gauged Linear Sigma Model quasimap invariants that generalize the original ones and are easier to compute. Higgs-Coulomb correspondence provides identification of generating functions of […]
Holographic Cone of Average Entropies and Universality of Black Holes
Speaker: Bartek Czech, Tsinghua University Title: Holographic Cone of Average Entropies and Universality of Black Holes Abstract: In the AdS/CFT correspondence, the holographic entropy cone, which identifies von Neumann entropies of CFT […]
Topological Quantum Gravity and the Ricci Flow – Part II
Abstract: In this sequence of talks, I will describe our work with Alexander Frenkel and Stephen Randall, in which we presented a novel topological quantum gravity, relating three previously unrelated […]
Donaldson-Thomas invariants and hyperkahler manifolds: the example of theories of class S[A1]
Abstract: I will report on a project which aims to encode the DT invariants of a CY3 triangulated category in a geometric structure on its stability space. I will focus on […]
Extreme Black Holes: Anabasis and Accidental Symmetry
https://youtu.be/USKZjJ8_LI0 Speaker: Achilleas Porfyriadis, Harvard Black Hole Initiative Title: Extreme Black Holes: Anabasis and Accidental Symmetry Abstract: The near-horizon region of black holes near extremality is universally AdS_2-like. In this […]
