Energy flow through open, driven quantum systems — •Matthias Langemeyer and Martin Holthaus — Institute of Physics, Carl von Ossietzky University, 26111 Oldenburg, Germany

Recently, there has been some interest in quantum systems which are driven by an external time-periodic force on the one hand, and in thermal contact with a heat bath on the other [1,2,3]. Such systems are conveniently described by a Pauli-type master equation formulated in a basis of Floquet states. After briefly reviewing the basic formalism, we consider a particularly simple example which allows one to calculate the energy flow through the system analytically.
