The Sign Problem is the Solution

Abstract

The unquenched spectral density of the Dirac operator at μ0\mu\neq0 is complex and has oscillations with a period inversely proportional to the volume and an amplitude that grows exponentially with the volume. Here we show how the oscillations lead to the discontinuity of the chiral condensate.
