Nonrelativistic Green's Function for Systems with Position-Dependent Mass [PDF]

open access: yesInternational Journal of Theoretical Physics, 2003
Given a spatially dependent mass we obtain the two-point Green's function for exactly solvable nonrelativistic problems. This is accomplished by mapping the wave equation for these systems into well-known exactly solvable Schrodinger equations with constant mass using point canonical transformation.
