Training Energy-Based Models with Non-MCMC Samplers and Efficient Temperature Estimation

Efficient sampling from Boltzmann distributions over discrete variables is a fundamental operation in a wide range of applications. While fast non-Markov chain Monte Carlo (MCMC) samplers have recently emerged as promising alternatives to conventional MCMC methods, their practica...

Phase-shift Instanton Approach to Tunneling Duality in Read–Rezayi State

We study the duality between quasi-particle and electron tunneling in point-contact geometries of fractional quantum Hall states. To treat non-Abelian edge operators, we introduce a “phase-shift instanton” that incorporates phase factors from primary fields into the instanton gas...
