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…
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…
The roles of quantum coherence in thermodynamic processes
Jingyi Chen, Guozhen Su, Jincan Chen +1
Quantum coherence associated with the superpositions of two different sets of eigenbasis vectors has been regarded as essential in thermodynamics. It is found that coherent factors…
Finite-time quantum measurement cooling beyond the Carnot limit
Tong Fu, Jianying Du, Jingyi Chen +3
We proposed the finite-time cycle model of a measurement-based quantum cooler, where invasive measurement provides the power to drive the cooling cycle. Such a cooler may be regard…
The reverse flow and amplification of heat in a quantum-dot system
Jianying Du, Tong Fu, Jingyi Chen +2
We demonstrate that when a quantum dot is embedded between the two reservoirs described by different statistical distribution functions, the reverse flow and amplification of heat…
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…
