Manifestation of superposition and coherence in -symmetry through the η-inner product

Abstract

Through the η-inner product, we investigate -symmetric quantum mechanics from the viewpoint of superposition and coherence theory. It is argued that -symmetric quantum systems are endowed with stationary superposition or superposition-free properties. A physical interpretation of η-inner product in is given through the Stokes parameters, showing the difference between broken and unbroken -symmetric quantum systems.
