Abstract :
The solution of the Wigner equation, using the Monte Carlo method [1] along with the signed-particle technique [2], requires a finite coherence length to be chosen. We investigate how the choice of the coherence length influences computational aspects of the calculation of the Wigner potential, like momentum resolution. Additionally, the physical interpretation attributed to a chosen coherence length is discussed.
