Fermion condensates of massless two-dimensional QED at finite density in nontrivial topological sector
Vacuum expectation values of products of local bilinears ψ¯ψ are computed in massless two-dimensional QED at finite density. It is shown that chiral condensates exhibit an oscillatory inhomogeneous behavior depending on the chemical potential. The use of a path integral approach clarifies the connec...

description |
Vacuum expectation values of products of local bilinears ψ¯ψ are computed in massless two-dimensional QED at finite density. It is shown that chiral condensates exhibit an oscillatory inhomogeneous behavior 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 |
