Quantum trajectories from a discrete-variable representation method.
A method for obtaining quantum trajectories from a discrete-variable representation computation of the quantum potential is presented. The method exploits the linearity of the Schrödinger equation, deals smoothly with the quantum potential singularities, and readily performs the time propagation up to fairly large total elapsed times. A one-dimensional test of the general n-dimensional formulation is included.
