Time-dependent version of cryptohermitian quantum theory
arXiv:0809.2874 · doi:10.1103/PhysRevD.78.085003
Abstract
For many quantum models an apparent non-Hermiticity of observables corresponds to their hidden Hermiticity in another, physical Hilbert space. For these models we show that the existence of observables which are manifestly time-dependent may require the use of a manifestly time-dependent representation of the physical Hilbert space of states.
