Thermodynamic analysis of autonomous quantum systems
Tiago F. F. Santos, Camille Latune
Traditional quantum thermodynamic frameworks associate work to energy exchanges induced by unitary transformations generated by external controls, and heat to energy exchanges indu…
Cooperative isentropic charging of hybrid quantum batteries
Yohan Vianna de Almeida, Tiago F. F. Santos, Marcelo F. Santos
Quantum batteries are quantum systems used to store energy to be later extracted by an external agent in the form of work to perform some task. Here we study the charging of a hybr…
Vacuum enhanced charging of a quantum battery
Tiago F. F. Santos, Yohan Vianna de Almeida, Marcelo F. Santos
Quantum batteries are quantum systems that store energy which can then be used for quantum tasks. One relevant question about such systems concerns the differences and eventual adv…
Efficiency of optically pumping a quantum battery and a two-stroke heat engine
Tiago F. F. Santos, Marcelo F. Santos
In this work, we study the efficiency of charging a quantum battery through optical pumping. The battery consists of a qutrit and it is connected to a natural thermal reservoir and…
Maximally effcient quantum thermal machines fuelled by nonequilibrium steady states
Tiago F. F. Santos, Francesco Tacchino, Dario Gerace +2
The concept of thermal machines has evolved from the canonical steam engine to the recently proposed nanoscopic quantum systems as working fluids. The latter obey quantum open syst…
Charging a quantum battery via non equilibrium heat current
Francesco Tacchino, Tiago F. F. Santos, Dario Gerace +2
When a quantum system is subject to a thermal gradient it may sustain a steady non-equilibrium heat current, by entering into a so-called non equilibrium steady state (NESS). Here…
