i now need to integrate the time-dependent schrodinger equation in 2D
the potential is rotationally invariant and so is the initial wave function
thus the symmetry of the initial wave function will be preserved in time
Instead of a 2D equation, i now only need to integrate a 1d equation about the radial part of the wave function.
However, in doing so i encounter some difficulties. There are terms like 1/r \partial_r in the equation.
near the origin, this term will diverge!
I guess this is a well-solved problem. Could anyone give me some help?
