    • Abstract

       

      We present an evaluation of some recent attempts to understand the role of pseudo-Hermitian and $\mathcal{PT}$-symmetric Hamiltonians in modelling unitary quantum systems and elaborate on a particular physical phenomenon whose discovery originated in the study of complex scattering potentials.
