Quantum thermodynamically consistent local master equations
Adam Hewgill, Gabriele De Chiara, Alberto Imparato
Local master equations are a widespread tool to model open quantum systems, especially in the context of many-body systems. These equations, however, are believed to lead to thermo…
Three-qubit refrigerator with two-body interactions
Adam Hewgill, J. Onam González, José J. Palao +3
We propose a three-qubit setup for the implementation of a variety of quantum thermal machines where all heat fluxes and work production can be controlled. An important configurati…
Reconciliation of quantum local master equations with thermodynamics
G. De Chiara, G. Landi, A. Hewgill +4
The study of open quantum systems often relies on approximate master equations derived under the assumptions of weak coupling to the environment. However when the system is made of…
Quantum correlations and thermodynamic performances of two-qubit engines with local and collective baths
Adam Hewgill, Alessandro Ferraro, Gabriele De Chiara
We investigate heat engines whose working substance is made of two coupled qubits performing a generalised Otto cycle by varying their applied magnetic field or their interaction s…
