Experimental Implementation of a NMR NOON State Thermomete
C. V. H. B. Uhlig, R. S. Sarthour, I. S. Oliveira +1
Utilizing the highly correlated quantum NOON states of particles, we have implemented a proof-of-principle quantum thermometer using the NMR technique for measuring the variation o…
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…
Experimental characterization of a spin quantum heat engine
John P. S. Peterson, Tiago B. Batalhão, Marcela Herrera +4
Developments in the thermodynamics of small quantum systems envisage non-classical thermal machines. In this scenario, energy fluctuations play a relevant role in the description o…
