Universal optimization efficiency and bounds of Carnot-like heat engines and refrigerators under shortcuts to isothermality
Yanchao Zhang, Shuang Wang
Based on a quantum thermodynamic protocol for shortcut to isothermality that smoothly modify the system-reservoir interaction can significantly speed up an isothermal process while…
Inverse currents in Coulomb-coupled quantum dots
Yanchao Zhang, Zhenzhen Xie
The inverse current, i.e., induced current is opposite to applied force, has recentlybeen found in a classical one-dimensional interacting Hamiltonian system [Phys. Rev.Lett. 124,…
Optimization performance of quantum Otto heat engines and refrigerators with squeezed thermal reservoirs
Yanchao Zhang
We consider a quantum Otto cycle operating between two squeezed thermal reservoirs. The influences of the squeezing degree on the optimization performance of quantum Otto heat engi…
Quantum coherence thermal transistors
Shanhe Su, Yanchao Zhang, Bjarne Andresen +1
Coherent control of self-contained quantum systems offers the possibility to fabricate smallest thermal transistors. The steady coherence created by the delocalization of electroni…
