ExitTime.mov from Numerical path integral calculation of the probability function and exit time: an application to non-gradient drift forces

Temporal Evolution of the Probability Distribution Function computed by the Path Integral Scheme for the bistable 2D model (3.5)-(3.6) of Supplementay Information (or (4.2) of Main Paper) with absorbent boundary conditions at x=0 for all y. Notice the probability loss.
