Pseudo-Hermitian potential models with PT symmetry☆

摘要: Abstract Complexfying a five-parameter exponential-type potential with shape invariance, we obtain the generalized complex versions of Rosen–Morse well, Scarf, Eckart and Poschl–Teller potentials. It has been shown that theses are P -pseudo-Hermitian PT -symmetric. For former two potentials, parity operator  acts on position operator as PxP −1 = ln q α −x , and  =− x for latter
