Abstract: In this paper, we introduce a class of novel PT- δ-hyperbolic-function potentials composed of the Dirac δ(x) and hyperbolic functions, supporting fully real energy spectra in the non-Hermitian Hamiltonian. The threshold curves of PT symmetry… read more here.

Abstract: The stationary solution and the dynamical evolution of the fundamental and higher eigenmodes of the parity-time ( $ \mathcal {PT} $ PT) symmetric coupled system with self-defocusing Kerr nonlinearity have been analysed. The eigenstates of… read more here.
