• Three-particle mechanism for pairing and superconductivity

    Virtual

    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

    Virtual

    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.

  • Small Cosmological Constants in String Theory

    Abstract: We construct supersymmetric AdS4 vacua of type IIB string theory in compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit orientifolds and quantized fluxes for which the […]

  • Symmetry types in QFT and the CRT theorem

    Virtual

    Title: Symmetry types in QFT and the CRT theorem Abstract: I will discuss ideas around symmetry and Wick rotation contained in joint work with Mike Hopkins (https://arxiv.org/abs/1604.06527). This includes general […]

  • The number of n-queens configurations

    Virtual

    Speaker: Michael Simkin, Harvard CMSA Title: The number of n-queens configurations Abstract: The n-queens problem is to determine Q(n), the number of ways to place n mutually non-threatening queens on an […]

  • Applications of instantons, sphalerons and instanton-dyons in QCD

    Virtual

    Title: Applications of instantons, sphalerons and instanton-dyons in QCD Abstract: I start with a general map of gauge topology, including monopoles, instantons and instanton-dyons. Then comes reminder of the “topological […]

  • The many phases of a cell

    Abstract: I will begin by introducing an emerging paradigm of cellular organization – the dynamic compartmentalization of biochemical pathways and molecules by phase separation into distinct and multi-phase condensates. Motivated […]
