Non-unitary transformation approach to $\mathcal{P}\mathcal{T}$ dynamics

Abstract

We show that several Hamiltonians that are $\mathcal{P}\mathcal{T}$ symmetric may be taken to Hermitian Hamiltonians via a non-unitary transformation and vice versa. We also show that for some specific Hamiltonians such non-unitary transformations may be associated, via a fractional-Wick rotation, to complex time.
