“Exotic 3D topologically ordered states”

MATHEMATICAL PICTURE LANGUAGE

January 7, 2020      3:30 pm
Speaker: Jin-Long Huang - University of California at San Diego

In the search for finite temperature quantum memory, people have found an exotic 3D topological model, called the fracton model. A large class of them are known to have foliation...

Singular Hermitian-Yang-Mills connections and reflexive sheaves

GAUGE-TOPOLOGY-SYMPLECTIC

December 6, 2019      3:30 pm
Speaker: Song Sun - Berkeley

The Donaldson-Uhlenbeck-Yau theorem relates the existence of Hermitian-Yang-Mills connections over a compact Kahler manifold with algebraic stability of a holomorphic vector bundle. This has been extended by Bando-Siu in 1994 to a class...

From para-Hermitian geometry to mirror symmetry

CMSA GENERAL RELATIVITY SEMINAR

November 25, 2019      12:00 pm
Speaker: David Svoboda - Perimeter Institute

In recent years, para-Hermitian geometry has been used to describe T-duality covariant spacetimes for string theory. In my talk, I will present applications of para-Hermitian geometry to 2D (2,2) SUSY...

Universal signatures of a black hole’s photon ring

CMSA GENERAL RELATIVITY SEMINAR

November 22, 2019      10:30 am
Speaker: Shahar Hadar - Harvard University

The Event Horizon Telescope image of the supermassive black hole in the galaxy M87 is dominated by a bright, unresolved ring. General relativity predicts that embedded within this image lies...
