Entropy-based analysis of single-qubit Otto and Carnot heat engines
Andrés Vallejo, Catty Lissardy, Santiago Silva-Gallo +2
From an entropy-based formulation of the first law of thermodynamics in the quantum regime, we investigate the performance of Otto-like and Carnot-like engines for a single-qubit w…

Evolution of expected values in open quantum systems
Andrés Vallejo, Alejandro Romanelli, Virginia Feldman +1
We derive a generalization of Ehrenfest theorem valid for open quantum systems. From this result, we identify three contributions to the evolution of expected values: i) the explic…
