Work exchange between quantum systems: the spin-oscillator model
Heiko Schröder, Günter Mahler
With the development of quantum thermodynamics it has been shown that relaxation to thermal equilibrium and with it the concept of heat flux may emerge directly from quantum mechan…
The Clausius inequality beyond the weak coupling limit: The quantum Brownian oscillator revisited
ILki Kim, Guenter Mahler
We consider a quantum linear oscillator coupled at an arbitrary strength to a bath at an arbitrary temperature. We find an exact closed expression for the oscillator density operat…
Transport in anisotropic model systems analyzed by a correlated projection superoperator technique
Hendrik Weimer, Mathias Michel, Jochen Gemmer +1
By using a correlated projection operator, the time-convolutionless (TCL) method to derive a quantum master equation can be utilized to investigate the transport behavior of quantu…
Cavity-induced temperature control of a two-level system
Hendrik Weimer, Günter Mahler
We consider a two-level atom interacting with a single mode of the electromagnetic field in a cavity within the Jaynes-Cummings model. Initially, the atom is thermal while the cavi…
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…
