Quantum Otto engine with quantum correlations
Yang Xiao, Dehua Liu, Jizhou He +3
We theoretically prose and investigate a photo-Otto engine that is working with a single-mode radiation field inside an optical cavity and alternatively driven by a hot and a cold…
Quantum refrigerators in finite-time cycle duration
Guangqian Jiao, Shoubao Zhu, Jizhou He +2
We derive cooling rate and coefficient of performance as well as their variances for a quantum Otto engine proceeding in finite-time cycle period. This machine consists of two driv…
Quantum heat engine based on trapped Bose gases: Its maximum efficiency can approach the Carnot value at finite power
Jianhui Wang, Jizhou He, Yongli Ma
It was reported that, if and only if the specific heat, correlation length, and dynamical exponents and , fulfill the condition , the phase transitions can enable…
Efficiency at maximum power of a quantum Otto engine: Both within finite-time and irreversible thermodynamics
Feilong Wu, Jizhou He, Yongli Ma +1
We consider the efficiency at maximum power of a quantum Otto engine, which uses a spin or a harmonic system as its working substance and works between two heat reservoirs at const…
Coefficient of performance under maximum criterion in a two-level atomic system as a refrigerator
Yuan Yuan, Rui Wang, Jizhou He +2
A two-level atomic system as a working substance is used to set up a refrigerator consisting of two quantum adiabatic and two isochoric processes (two constant-frequency processes…
Coefficient of performance for a low-dissipation Carnot-like refrigerator with nonadiabatic dissipation
Yong Hu, Feifei Wu, Yongli Ma +4
We study the coefficient of performance (COP) and its bounds of the Canot-like refrigerator working between two heat reservoirs at constant temperatures and , under two…
Quantum-mechanical engine models and their efficiencies
Jianhui Wang, Yongli Ma, Jizhou He
Based on quantum thermodynamic processes, we make a quantum-mechanical (QM) extension of the typical heat engine cycles, such as the Carnot, Brayton, Otto, and Diesel cycles, etc.…
