Nano-Thermodynamics: On the minimal length scale for the existence of temperature
M. Hartmann, G. Mahler, O. Hess
We consider a quantum system consisting of a regular chain of elementary subsystems with nearest neighbor interactions and assume that the total system is in a canonical state with…

Scaling behavior of interactions in a modular quantum system and the existence of local temperature
M. Hartmann, J. Gemmer, G. Mahler +1
We consider a quantum system of fixed size consisting of a regular chain of -level subsystems, where is finite. Forming groups of subsystems each, we show that the stren…
