abstract = {<p style="text-align: justify;">The rigorous relations between the propagators of transient Schrödinger
equations and stationary Green functions are established. Based on the generalized
Fourier transform, non-singular transparent boundary condition for transient problem is proposed in a representation of Green functions. The unified framework of
Green function method is presented for converting an open boundary problem into
a bounded boundary problem. Numerical scheme for time-dependent Schrödinger
equation with non-singular transparent boundary condition is designed to simulate
the propagations of a free Gaussian wave packet and the resonant tunnelling through
double barriers. Numerical results validate the effectiveness of non-singular transparent boundary condition.</p>},
