Gradient flows on totally nonnegative flag varieties
Abstract: One can view a partial flag variety in C^n as an adjoint orbit inside the Lie algebra of n x n skew-Hermitian matrices. We use the orbit context to […]

Swampland Program
During the 2021–2022 academic year, the CMSA will host a program on the so-called “Swampland.” The Swampland program aims to determine which low-energy effective field theories are consistent with nonperturbative quantum gravity considerations. Not […]
Decoding Divergent Distances
Speaker: John Stout, Harvard University Title: Decoding Divergent Distances Abstract: Motivated by a relationship between the Zamolodchikov and NLSM metrics to the so-called quantum information metric, I will discuss recent work […]
Simplices in the Calabi–Yau web
Abstract: Calabi–Yau manifolds of a given dimension are connected by an intricate web of birational maps. This web has deep consequences for the derived categories of coherent sheaves on such manifolds, […]
Hyperbolic Geometry and Quantum Invariants
Speaker: Tian Yang (Texas A&M University) Title: Hyperbolic Geometry and Quantum Invariants Abstract: There are two very different approaches to 3-dimensional topology, the hyperbolic geometry following the work of Thurston and the quantum invariants […]

Why abstraction is the key to intelligence, and what we’re still missing
https://youtu.be/3Nxe7J07TQY Speaker: Francois Chollet, Google Title: Why abstraction is the key to intelligence, and what we’re still missing Abstract: This talk provides a personal perspective on the way forward towards more […]
Three-particle mechanism for pairing and superconductivity
Title: Three-particle mechanism for pairing and superconductivity Abstract: I will present a new mechanism and an exact theory of electron pairing due to repulsive interaction in doped insulators. When the […]
The Hilbert Space of large N Chern-Simons matter theories
Title: The Hilbert Space of large N Chern-Simons matter theories Abstract: We demonstrate that all known formulae for the thermal partition function for large N Chern Simons matter theory admit […]
9/17/2021 General Relativity Seminar
Title: Stable Big Bang formation for the Einstein equations Abstract: I will discuss recent work concerning stability of cosmological singularities described by the generalized Kasner solutions. There are heuristics in […]
Geometry, Entanglement and Quasi Local Data
Member Seminar Speaker: Itamar Shamir Title: Geometry, Entanglement and Quasi Local Data Abstract: I will review some general ideas about gravity as motivation for an approach based on quasi local quantities.
Strong Coupling Theory of Magic-Angle Graphene: A Pedagogical Introduction
Title: Strong Coupling Theory of Magic-Angle Graphene: A Pedagogical Introduction Abstract: In this talk, I will review a recently developed strong coupling theory of magic-angle twisted bilayer graphene. An advantage […]
