Thermoelectric transport in nanosystems: A hierarchical quantum master equation approach — •Jakob Bätge, Ka Chun Chan, and Michael Thoss — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, Germany

A variety of interesting transport phenoma exist in nanoelectronic systems. Recently, quantization of heat transport has been observed [1] and counterintuitive thermal stabilization in molecular junctions has been predicted [2]. In this context, we investigate voltage and temperature driven electron and heat transport from a theoretical point of view. In particular, we are interested in the interplay of electronic and vibrational degrees of freedom. For this purpose, we use the hierarchical quantum master equation method [3], which generalizes perturbative master equation methods by including higher-order contributions as well as non-Markovian memory and allows for the systematic convergence of the results.
