A Comment On Topological Degeneracy In Gauged WZW Models
Gregory W. Moore, Eliezer Rabinovici, Ranveer Kumar Singh
Given a Lie group , a level , and a Lie subgroup one can construct 2d conformal field theories by either 1.) gauging a nonanomalous symmetry of the WZW model construc…
Beauty And The Beast Part 2: Apprehending The Missing Supercurrent
Gregory W. Moore, Ranveer Kumar Singh
The Moonshine module is a conformal field theory (CFT) whose automorphism group is the Monster group. It was argued by Dixon, Ginsparg, and Harvey in \cite{Dixon:1988qd} tha…
TASI Lectures On Topological Field Theories And Differential Cohomology
Gregory W. Moore, Vivek Saxena
These are lecture notes expanding upon a set of lectures given by G.M. at the TASI 2023 School. Part I is an introduction to topological field theory, including extended topologica…
Topological Twisting of 4d Supersymmetric Field Theories
Gregory W. Moore, Vivek Saxena, Ranveer Kumar Singh
We discuss what topological data must be provided to define topologically twisted partition functions of four-dimensional supersymmetric field theories. The origina…
