Minimal Energy Cost to Initialize a Quantum Bit with Tolerable Error
Yu-Han Ma, Jin-Fu Chen, C. P. Sun +1
Landauer's principle imposes a fundamental limit on the energy cost to perfectly initialize a classical bit, which is only reached under the ideal operation with infinite-long time…
Quantum-classical correspondence principle for heat distribution in quantum Brownian motion
Jin-Fu Chen, Tian Qiu, H. T. Quan
Quantum Brownian motion, described by the Caldeira-Leggett model, brings insights to understand phenomena and essence of quantum thermodynamics, especially the quantum work and hea…
Geodesic path for the minimal energy cost in shortcuts to isothermality
Geng Li, Jin-Fu Chen, C. P. Sun +1
Shortcut to isothermality is a driving strategy to steer the system to its equilibrium states within finite time, and enables evaluating the impact of a control promptly. Finding o…
Efficiency statistics of a quantum Otto cycle
Zhayu Fei, Jin-Fu Chen, Yu-Han Ma
The stochastic efficiency [G. Verley et al., Nat. Commun. 5, 4721 (2014)] was introduced to evaluate the performance of energy-conversion machines in micro-scale. However, such an…
A microscopic theory of Curzon-Ahlborn heat engine
Y. H. Chen, Jin-Fu Chen, Zhaoyu Fei +1
Abstract The Curzon-Ahlborn (CA) efficiency, as the efficiency at the maximum power (EMP) of the endoreversible Carnot engine, has a significant impact on finite-time thermodynamic…
Extrapolating the thermodynamic length with finite-time measurements
Jin-Fu Chen, C. P. Sun, Hui Dong
The excess work performed in a heat-engine process with given finite operation time τis bounded by the thermodynamic length, which measures the distance during the relaxation along…
