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…
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…
Centenary progress from the Nernst theorem to the Nernst statement
Xiaohang Chen, Shanhe Su, Yinghui Zhou +1
It is found from textbooks that there are the different versions of the schematic diagram related to the Nernst equation, and consequently, it leads to some discussion related to t…
A new succinct proof on the equivalence of the Nernst equation and the vanishing heat capacity at absolute zero temperature
Shanhe Su, Jincan Chen
By starting from the Euler chain rule of three thermodynamic quantities, it is proved that both the Nernst equation and the vanishing heat capacity at absolute zero temperature are…
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…
Breakthrough of a cross-century problematic issue:The perfect statements of the third law of thermodynamics
Xiaohang Chen, Shanhe Su, Yinghui Zhou +1
The third law of thermodynamics has been verified experimentally, but how to perfectly express such a law in theory has become a cross-century problematic issue. It is found from t…
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…
Nonequilibrium free energy and information flow of a double quantum-dot system with Coulomb coupling
Zhiyuan Lin, Tong Fu, Juying Xiao +3
We build a double quantum-dot system with Coulomb coupling and aim at studying the connections among the entropy production, free energy, and information flow. By utilizing the con…
