Transport in open spin chains: A Monte Carlo wave-function approach
Mathias Michel, Ortwin Hess, Hannu Wichterich +1
We investigate energy transport in several two-level atom or spin-1/2 models by a direct coupling to heat baths of different temperatures. The analysis is carried out on the basis…
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…
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…
Modeling heat transport through completely positive maps
Hannu Wichterich, Markus J. Henrich, Heinz-Peter Breuer +2
We investigate heat transport in a spin-1/2 Heisenberg chain, coupled locally to independent thermal baths of different temperature. The analysis is carried out within the framewor…
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…
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…
