Efficiency bounds for bipartite information-driven thermodynamic systems
Shihao Xia, Shuanglong Han, Ousi Pan +3
This study introduces a novel approach to derive a lower bound for the entropy production rate of a subsystem by utilizing the Cauchy-Schwarz inequality. It extends to establishing…
Performance optimization of a finite-time quantum tricycle
Jingyi Chen, Shihao Xia, Jincan Chen +1
We establish a finite-time external field-driven quantum tricycle model. Within the framework of slow driving perturbation, the perturbation expansion of heat in powers of time can…
Theoretical bound of the efficiency of learning with coarse-graining
Minghao Li, Shihao Xia, Youlin Wang +2
A thermodynamic formalism describing the efficiency of information learning is proposed, which is applicable for stochastic thermodynamic systems with multiple internal degree of f…
Performance improvement of a fractional quantum Stirling heat engine
Shihao Xia, Youlin Wang, Minglong Lv +2
To investigate the impact of fractional parameter on the thermodynamic behaviors of quantum systems, we incorporate fractional quantum mechanics into the cycle of a quantum Stirlin…
