Quantum Thermal Rectification to Design Thermal Diodes and Transistors [PDF]
Zeitschrift für Naturforschung A, 2017 Abstract We study in this article how heat can be exchanged between two-level systems, each of them being coupled to a thermal reservoir. Calculations are performed solving a master equation for the density matrix using the Born–Markov approximation.
