Abstract
We formulate quantum mechanics for non-Hermitian Hamiltonians that are invariant under , where is the parity and denotes time reversal, for the case that time-reversal symmetry is odd (), generalizing prior work for the even case (). We discover an analog of Kramer’s theorem for quantum mechanics, present a prototypical example of a quantum system with odd time reversal, and discuss potential applications of the formalism.
