Model Studies on the Quantum Jarzynski Relation
Jens Teifel, Günter Mahler
We study the quantum Jarzynski relation for driven quantum models embedded in various environments. We do so by generalizing a proof presented by Mukamel [Phys. Rev. Lett 90, 17060…
Driven Spin Systems as Quantum Thermodynamic Machines: Fundamental Limits
M. J. Henrich, M. Michel, G. Mahler
We show that coupled two level systems like qubits studied in quantum information can be used as a thermodynamic machine. At least three qubits or spins are necessary and arranged…
Small quantum networks operating as quantum thermodynamic machines
M. J. Henrich, M. Michel, G. Mahler
We show that a 3-qubit system as studied for quantum information purposes can alternatively be used as a thermodynamic machine when driven in finite time and interfaced between two…
Application of the Hilbert Space Average Method on Heat Conduction Models
Mathias Michel, Jochen Gemmer, Guenter Mahler
We analyze closed one-dimensional chains of weakly coupled many level systems, by means of the so-called Hilbert space average method (HAM). Subject to some concrete conditions on…
Fourier's Law from Schroedinger Dynamics
Mathias Michel, Guenter Mahler, Jochen Gemmer
We consider a class of one-dimensional chains of weakly coupled many level systems. We present a theory which predicts energy diffusion within these chains for almost all initial s…
Global and local relaxation of a spin-chain under exact Schroedinger and master-equation dynamics
Markus J. Henrich, Mathias Michel, Michael Hartmann +2
We solve the Schroedinger equation for an interacting spin-chain locally coupled to a quantum environment with a specific degeneracy structure. The reduced dynamics of the whole sp…
