Quantum Coherence as a Thermodynamic Resource Beyond the Classical Uncertainty Bound
Shanhe Su, Cong Fu, Ousi Pan +3
Thermodynamic uncertainty relations (TURs) establish a fundamental trade-off between current precision and entropy production in nonequilibrium systems, yet the role of genuine qua…
Balancing Power, Efficiency, and Constancy under Broken Time-Reversal Symmetry
Ousi Pan, Zhiqiang Fan, Shunjie Zhang +3
We derive general trade-off relations among the power, efficiency, and constancy for two-terminal thermoelectric systems in the linear response regime. Constancy, which quantifies…
Fluctuation-Dissipation Limits in Quantum Thermoelectric Transport
Ousi Pan, Zhiqiang Fan, Shunjie Zhang +3
As a fundamental measure of stability in nonequilibrium thermodynamics, fluctuations provide critical insight into the performance and reliability of heat engines. In this work, we…
Unlocking inaccessible performance of the quantum refrigerator with catalysts
Cong Fu, Ousi Pan, Zhiqiang Fan +4
Quantum thermal machines offer promising platforms for exploring the fundamental limits of thermodynamics at the microscopic scale. The previous study demonstrated that the incorpo…
Geometric Bound for Trade-off Relation in Quantum Tricycle
Shihao Xia, Jingyi Chen, Jincan Chen +1
We establish a finite-time quantum tricycle driven by an external field and investigate its thermodynamic performance in the slow-driving regime. By developing a perturbative expan…
Theoretical bound of the efficiency of learning
Shanhe Su, Ousi Pan, Shihao Xia +2
A unified thermodynamic formalism describing the efficiency of learning is proposed. First, we derive an inequality, which is more strength than Clausius's inequality, revealing th…
