No evidence for bilinear condensate in parity-invariant three-dimensional QED with massless fermions

Nikhil Karthik, Rajamani Narayanan

Abstract

Numerical lattice simulations with a carefully taken continuum limit strongly indicate the absence of a bilinear condensate in three-dimensional massless QED for any even number of two-component fermions, ${N}_{f}\ensuremath{\ge}2$, solving a long-standing open question.
