Performance of Reservoir Discretizations in Quantum Transport Simulations

September 29, 2021
Author(s)
Justin E. Elenewski, Gabriela Wojtowicz, Marek Rams, Michael P. Zwolak
Quantum transport simulations require a level of discretization, often achieved through an explicit representation of the electronic reservoirs. These representations should converge to the same continuum limit, though there is a trade-off between a given
