Fermion Condensates of massless $QE{D}_2$ at Finite Density in non-trivial Topological Sectors

Abstract

Vacuum expectation values of products of local bilinears $\bar{\psi }\psi$ are computed in massless $QE{D}_2$ at finite density. It is shown that chiral condensates exhibit an oscillatory inhomogeneous behaviour depending on the chemical potential. The use of a path-integral approach clarifies the connection of this phenomenon with the topological structure of the theory.
