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…
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 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…
Suppressing coherence effects in quantum-measurement based engines
Zhiyuan Lin, Shanhe Su, Jingyi Chen +2
The recent advances in the study of thermodynamics of microscopic processes have driven the search for new developments in energy converters utilizing quantum effects. We here prop…
The heat and work of quantum thermodynamic processes with quantum coherence
Shan-He Su, Jin-Fu Chen, Yu-Han Ma +2
Energy is often partitioned into heat and work by two independent paths corresponding to the change in the eigenenergies or the probability distributions of a quantum system. The d…
Photoelectric converters with quantum coherence
Shan-He Su, Chang-Pu Sun, Sheng-Wen Li +1
Photon impingement is capable of liberating electrons in electronic devices and driving the electron flux from the lower chemical potential to higher chemical potential. Previous s…
