Efficiency of a quantum Otto heat engine operating under a reservoir at effective negative temperatures
Rogério J. de Assis, Taysa M. de Mendonça, Celso J. Villas-Boas +4
Abstract We perform an experiment in which a quantum heat engine works under two reservoirs, one at a positive spin temperature and the other at an effective negative spin temperat…

Feasible platform to study negative temperatures
R. J. de Assis, C. J. Villas-Boas, N. G. de Almeida
We afford an experimentally feasible platform to study Boltzmann negative temperatures. Our proposal takes advantage of well-known techniques of engineering Hamiltonian to achieve…
