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…
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…
Small quantum networks operating as quantum thermodynamic machines
M. J. Henrich, M. Michel, G. Mahler
We show that a 3-qubit system as studied for quantum information purposes can alternatively be used as a thermodynamic machine when driven in finite time and interfaced between two…
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…
