Emergence of thermodynamic behavior within composite quantum systems
Guenter Mahler, Jochen Gemmer, Mathias Michel
Entanglement within a given device provides a potential resource for quantum information processing. Entanglement between system and environment leads to decoherence (thus suppress…
From Pure Schroedingerian to Statistical Dynamics
Jochen Gemmer, Mathias Michel
Many processes in nature seem to be entirely controlled by transition rates and the corresponding statistical dynamics. Some of them are in essence quantum, like the decay of excit…
Quantum Heat Transport: Perturbation Theory in Liouville Space
Mathias Michel, Jochen Gemmer, Guenter Mahler
We consider chains consisting of several identical subsystems weakly coupled by various types of next neighbor interactions. At both ends the chain is coupled to a respective heat…
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…
Fourier's Law confirmed for a class of small quantum systems
Mathias Michel, Michael Hartmann, Jochen Gemmer +1
Within the Lindblad formalism we consider an interacting spin chain coupled locally to heat baths. We investigate the dependence of the energy transport on the type of interaction…
Heat conductivity in small quantum systems: Kubo formula in Liouville space
Mathias Michel, Jochen Gemmer, Guenter Mahler
We consider chains consisting of several identical subsystems weakly coupled by various types of next neighbor interactions. At both ends the chain is coupled to a respective heat…
