Geodesic bound of the minimum energy expense to achieve membrane separation within finite time
Jin-Fu Chen, Ruo-Xun Zhai, C. P. Sun +1
To accomplish a task within limited operation time typically requires an excess expense of energy, whose minimum is of practical importance for the optimal design in various applic…
Hierarchical structure of fluctuation theorems for a driven system in contact with multiple heat reservoirs
Jin-Fu Chen, H. T. Quan
For driven open systems in contact with multiple heat reservoirs, we find the marginal distributions of work or heat do not satisfy any fluctuation theorem, but only the joint dist…
Optimizing Brownian heat engine with shortcut strategy
Jin-Fu Chen
Shortcuts to isothermality provide a powerful method to speed up quasistatic thermodynamic processes within finite-time manipulation. We employ the shortcut strategy to design and…
Speeding up quantum adiabatic processes with dynamical quantum geometric tensor
Jin-Fu Chen
For adiabatic controls of quantum systems, the non-adiabatic transitions are reduced by increasing the operation time of processes. Perfect quantum adiabaticity usually requires th…
