Finite quantum environments as thermostats: an analysis based on the Hilbert space average method
Jochen Gemmer, Mathias Michel
We consider discrete quantum systems coupled to finite environments which may possibly consist of only one particle in contrast to the standard baths which usually consist of conti…
Microscopic Quantum Mechanical Foundation of Fourier's Law
Mathias Michel, Jochen Gemmer, Günter Mahler
Besides the growing interest in old concepts like temperature and entropy at the nanoscale, theories of relaxation and transport have recently regained a lot of attention. With the…
Normal Transport Behavior in Finite One-Dimensional Chaotic Quantum Systems
Robin Steinigeweg, Jochen Gemmer, Mathias Michel
We investigate the transport of energy, magnetization, etc. in several finite one-dimensional (1D) quantum systems only by solving the corresponding time-dependent Schroedinger equ…
Limited validity of the Kubo formula for thermal conduction in modular quantum systems
Jochen Gemmer, Mathias Michel, Robin Steinigeweg
The Kubo formula describes a current as a response to an external field. In the case of heat conduction there is no such external field. We analyze why and to what extend it is nev…
