Relaxation of a Simple Quantum Random Matrix Model
Pedro Vidal, Günter Mahler
We will derive here the relaxation behavior of a simple quantum random matrix model. The aim is to derive the effective equations which rise when a random matrix interaction is tak…
Effective environments: Preparation of stationary states with inverse temperature ranging from positive to negative values
Thomas Jahnke, Günter Mahler
In this paper, we discuss how effective environments incorporating periodic measurements can be used to prepare a two-level system (TLS) in almost arbitrary thermal states: Concret…
Quantum thermodynamic processes: A control theory for machine cycles
Jan Birjukov, Thomas Jahnke, Günter Mahler
The minimal set of thermodynamic control parameters consists of a statistical (thermal) and a mechanical one. These suffice to introduce all the pertinent thermodynamic variables;…
Local effective dynamics of quantum systems: A generalized approach to work and heat
Hendrik Weimer, Markus J. Henrich, Florian Rempp +2
By computing the local energy expectation values with respect to some local measurement basis we show that for any quantum system there are two fundamentally different contribution…
A Cyclic Cooling Algorithm
F. Rempp, M. Michel, G. Mahler
We introduce a scheme to perform the cooling algorithm, first presented by Oscar Boykin et al. in 2002, for an arbitrary number of times on the same set of qbits. We achieve this g…
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…
