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…
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…
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…
Performance optimization of Nernst-based thermionic engines
Wei Yan, Minglong Lv, Ousi Pan +3
In this paper, we examine the power and efficiency of the thermionic device utilizing the Nernst effect, with a specific focus on its potential application as an engine. The device…
Hot-carrier photocatalysts with energy-selective contacts based on quantum wells and dots
Shuanglong Han, Zhiqiang Fan, Ousi Pan +5
In this paper, we simulate the function of hot-carrier photocatalysts (HCPCs) with quantum well and quantum dot energy-selective contacts (ESCs) in the water-splitting reaction. Th…
The effect of space charge on photon-enhanced thermionic emission in the presence of the bidirectional discharge
Xinqiao Lin, Ousi Pan, Zhimin Yang +3
The bidirectional space charge effects in photon-enhanced thermionic emission (PETE) devices are investigated systematically. First, we precisely determine the carrier concentratio…
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…
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…
