Wigner Ensemble Monte Carlo

Wigner Ensemble Monte Carlo (WEMC) is a C-based simulator supporting quantum transport simulations of nanoelectronic structures. The WEMC simulator solves the semi-discrete Wigner equation, using the signed-particle Monte Carlo method. The current user interface supports investigating the evolution of a minimum uncertainty wave packet (as an initial condition) in the presence of a square one-dimensional potential barrier. The code may be readily expanded for arbitrary initial conditions, potential profiles and arbitrary multidimensional structures.

The simulator offers parallel execution in a distributed-memory environment, using MPI. Further details can be found in [1][2].
