A generalization of the gauge-invariant Yang phase for open systems (described by non-Hermitian (NH) Hamiltonians) is derived by a biorthonormal-state approach. It is shown that the NH Yang phase is invariant under nonunitary bicanonical transformations.

Abstract
A generalization of the gauge-invariant Yang phase for open systems (described by non-Hermitian (NH) Hamiltonians) is derived by a biorthonormal-state approach. It is shown that the NH Yang phase is invariant under nonunitary bicanonical transformations.File in questo prodotto:
