Description

Many non-Hermitian but PT-symmetric Hamiltonians produce the quantum evolution that is unitary under the non-standard inner product. This allows us to interpret them in the pseudo-Hermitian way and relate to the well-behaved but very complicated quantum models through the non-unitary transformation. However for the generic PT-symmetric quantum field theory this transformation becomes non-local and causality issues arise. We explore possible ways to solve this problem.
