Abstract
The Wigner Monte Carlo solver, using the signed-particle method, is based on the generation and annihilation of numerical particles. The memory demands of the annihilation algorithm can become exorbitant, if a high spatial resolution is used, because the entire discretized phase space is represented in memory. Two alternative algorithms, which greatly reduce the memory requirements, are presented here.
