Abstract

In the present work we propose a generalization of tunneling time in parity and time (PT\mathcal{P}\mathcal{T})-symmetric systems. The properties of tunneling time in PT\mathcal{P}\mathcal{T}-symmetric systems are studied with a simple contact interactions periodic finite size diatomic PT\mathcal{P}\mathcal{T}-symmetric model. The physical meaning of negative tunneling time in PT\mathcal{P}\mathcal{T}-symmetric systems and its relation to spectral singularities is discussed.
