Temperature fluctuations in mesoscopic systems
Zhaoyu Fei, Yu-Han Ma
We study temperature fluctuations in mesoscopic -body systems undergoing non-equilibrium processes from the perspective of stochastic thermodynamics. By introducing a stochastic…
Experimental implementation of finite-time Carnot cycle
Ruo-Xun Zhai, Fang-Ming Cui, Yu-Han Ma +2
The Carnot cycle is a prototype of ideal heat engine to draw mechanical energy from the heat flux between two thermal baths with the maximum efficiency, dubbed as the Carnot effici…
Efficiency statistics of a quantum Otto cycle
Zhayu Fei, Jin-Fu Chen, Yu-Han Ma
The stochastic efficiency [G. Verley et al., Nat. Commun. 5, 4721 (2014)] was introduced to evaluate the performance of energy-conversion machines in micro-scale. However, such an…
Optimizing Thermodynamic Cycles with Two Finite-Sized Reservoirs
Hong Yuan, Yu-Han Ma, C. P. Sun
We study the non-equilibrium thermodynamics of a heat engine operating between two finite-sized reservoirs with well-defined temperatures. Within the linear response regime, it is…
The uniqueness of the integration factor associated with the exchanged heat in thermodynamics
Yu-Han Ma, Hui Dong, H. T. Quan +1
State functions play important roles in thermodynamics. Different from the process function, such as the exchanged heat and the applied work , the change of the state func…
