Phase of the fermion determinant at nonzero chemical potential

Phase of the fermion determinant at nonzero chemical potential

We show that in the microscopic domain of QCD (also known as the domain) at nonzero chemical potential the average phase factor of the fermion determinant is nonzero for micro
