We investigate quantum Otto engine and refrigeration cycles of a time-dependent harmonic
oscillator operating under the conditions of maximum Ω function, a trade-off objective …

We consider the finite-time performance of a quantum Otto engine working between a hot
squeezed and a cold thermal bath at inverse temperatures β h and β c (> β h) with (k B≡ 1) …

Thermodynamics is a theory of principles that permits a basic description of the macroscopic
properties of a rich variety of complex systems from traditional ones, such as crystalline …

Classical equilibrium thermodynamics is a theory of principles, which was built from
empirical knowledge and debates on the nature and the use of heat as a means to produce …

By means of advanced numerical simulation, the thermoelectric properties of a Si-quantum
dot-based single-electron transistor operating in sequential tunneling regime are …

The Curzon-Ahlborn efficiency has long served as the definite upper bound for the thermal
efficiency at maximum output power, and has thus shaped the development of finite-time …

Feynman's ratchet and pawl is a paradigmatic model for energy conversion using thermal
fluctuations in the mesoscopic regime. Here, we optimize the power output of the ratchet as …

Adaptable or adapted? Whether it is a question of physical, biological, or even economic
systems, this problem arises when all these systems are the location of matter and energy …

The exact power optimization of a thermoelectric generator is performed under the
simultaneous presence of internal and external irreversibilities—modeled as nonideal …

The metabolic processes complexity is at the heart of energy conversion in living organisms
and forms a huge obstacle to develop tractable thermodynamic metabolism models. By …
