摘要	In this paper, we consider two types of PT-symmetric non-periodic potentials (PT symmetric harmonic potential and harmonic-Gaussian potential) in the logarithmic nonlinear Schrodinger (LNLS) equation. The exact solitons are found, and shown to be stable for some parameter regions. The interactions are studied between two solitons in the LNLS equation with the two types of PT-symmetric potentials. Moreover, we also study the excitations of solitons in the LNLS equation with the PT-symmetric potentials containing the time-dependent functions. (C) 2022 Elsevier Ltd. All rights reserved.
