Performance of Reservoir Discretizations in Quantum Transport Simulations
Justin E. Elenewski, Gabriela Wójtowicz, Marek M. Rams +1
Quantum transport simulations often use explicit, yet finite, electronic reservoirs. These should converge to the correct continuum limit, albeit with a trade-off between discretiz…

Dual current anomalies and quantum transport within extended reservoir simulations
Gabriela Wojtowicz, Justin E. Elenewski, Marek M. Rams +1
Quantum transport simulations are rapidly evolving and now encompass well-controlled tensor network techniques for many-body limits. One powerful approach combines matrix product s…

Open System Tensor Networks and Kramers' Crossover for Quantum Transport
Gabriela Wojtowicz, Justin E. Elenewski, Marek M. Rams +1
Tensor networks are a powerful tool for many-body ground states with limited entanglement. These methods can nonetheless fail for certain time-dependent processes - such as quantum…
