Efficient steady state solver for the hierarchical equations of motion approach: Formulation and application to charge transport through nanosystems
Christoph Kaspar, Michael Thoss
An iterative approach is introduced, which allows the efficient solution of the hierarchical equations of motion (HEOM) for the steady state of open quantum systems. The approach c…

Nonequilibrium open quantum systems with multiple bosonic and fermionic environments: A hierarchical equations of motion approach
Jakob Bätge, Yaling Ke, Christoph Kaspar +1
We present a hierarchical equations of motion approach, which allows a numerically exact simulation of nonequilibrium transport in general open quantum systems involving multiple m…
