【 摘 要 】

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.
