A comment on a possible inadequacy of new redefinitions of heat and work in quantum thermodynamics
Eduardo B. Botosso, Jose S. Sales, Norton G. de Almeida
We analyze the new redefinitions of heat Q and work W recently presented in [arXiv: 1912.01939; arXiv:1912.01983v5] in the quantum thermodynamics domain. According to these redefin…
Quantum Otto Thermal Machines Powered by Kerr Nonlinearity
Udson C. Mendes, José S. Sales, Norton G. de Almeida
We study the effect of Kerr nonlinearity in quantum thermal machines having a Kerr-nonlinear oscillator as working substance and operating under the ideal quantum Otto cycle. We fi…
Universal two-level quantum Otto machine under a squeezed reservoir
Rogério J. de Assis, José S. Sales, Jefferson A. R. da Cunha +1
We study an Otto heat machine whose working substance is a single two-level system interacting with a cold thermal reservoir and with a squeezed hot thermal reservoir. By adjusting…
Two-level quantum Otto heat engine operating with unit efficiency far from the quasi-static regime under a squeezed reservoir
Rogério J. de Assis, J. S. Sales, Udson C. Mendes +1
Recent theoretical and experimental studies in quantum heat engines show that, in the quasi-static regime, it is possible to have higher efficiency than the limit imposed by Carnot…
Unambiguous discrimination of nonorthogonal quantum states in cavity QED
R. J. de Assis, J. S. Sales, N. G. de Almeida
We propose an oversimplified scheme to unambiguously discriminate nonorthogonal quantum field states inside high-Q cavities. Our scheme, which is based on positive operator-valued…
Light storage via coherent population oscillation in a thermal cesium vapor
A. J. F. de Almeida, J. Sales, M. -A. Maynard +5
We report on the storage of light via the phenomenon of Coherent Population Oscillation (CPO) in an atomic cesium vapor at room temperature. In the experiment the optical informati…
