Towards optimal asymptotic spectral gap in 2D unitary CFT
Sridip Pal
1:45pm|Bloomberg Hall Physics Library
We will prove a conjecture [1] on upper bound of asymptotic gap in dimension in unitary compact 2D CFT, proving it to be 1 using a "extremal" function [2]. The notion of asymptotic gap can be generalized to (h, \bar{h}) plane [3]. We will discuss...

Physics Group Meeting

Disordered Electronic Systems: Some Illustrative Vignettes
Ravindra Bhatt
1:45pm|Bloomberg Hall Physics Library
The physics of systems with quenched random disorder reveals behavior qualitatively different from that found in systems with translational symmetry, continuous or discrete. The seminal work by Anderson over six decades back [1] established the...

Physics Group Meeting

Topological Holography
Nafiz Ishtiaque
1:45pm|Bloomberg Hall Physics Library
We consider supersymmetric twist and omega deformation of a type IIB brane setup involving N D3 and K D5 branes. In the large N limit, this leads to a holographic duality between two topological/holomorphic theories. We compute certain operator...

The Geroch Group
Robert Penna
1:45pm|Bloomberg Hall Physics Library
We review some infinite dimensional symmetries that appear in dimensionally reduced classical general relativity. Reducing from d=4 to d=2 gives a two dimensional nonlinear sigma model with an infinite dimensional affine Kac-Moody symmetry called...
