Open system approach to transport

Abstract

In this section yet another approach to transport is examined. Rather than analyzing spatial energy density dynamics as done in the previous section, we now aim at investigating a stationary non-equilibrium state. This state is induced through the local coupling of reservoirs with different temperatures at either end of the system. The system is a chain of two-level systems coupled according to the Heisenberg model. The baths are modeled according to standard open system theory (see [3-6]). The resulting equations are numerically solved using a stochastic unraveling scheme. © 2009 Springer-Verlag Berlin Heidelberg.
