A variational approach to Schroedinger equation with parity-time symmetry Gaussian complex potential

Sumei Hu, Guo Liang, Shanyong Cai, Daquan Lu, Qi Guo, Wei Hu

A variational technique is established to deal with the Schrodinger equation with parity-time(PT) symmetric Gaussian complex potential. The method is extended to the linear and self-focusing and defocusing nonlinear cases. Some unusual properties in PT systems such as transverse power flow and PT breaking points can be analyzed by this method. Following numerical simulations, the analytical results are in good agreement with the numerical results.
