Title: PROPAGATOR FOR THE DELTA-FUNCTION POTENTIAL MOVING WITH CONSTANT VELOCITY
Author: CHENG, BK
DALUZ, MGE
Abstract: We first evaluate the exact propagator for a delta-function potential moving with constant velocity by summing over the spectrum of eigenstates and by calculating the path integral directly. The ''one-time Green's functions'' are then derived from the Fourier transform of the propagator obtained. We finally investigate the propagator through an asymptotic approximation.
