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,…
Thermal rectification and negative differential thermal conductivity based on a parallel-coupled double quantum-dot
Yanchao Zhang, Shanhe Su
We investigate the heat flow transport properties of a parallel-coupled double quantum-dot system connected to two reservoirs with a temperature bias in the Coulomb blockade regime…
Suspended photonic crystal membranes in AlGaAs heterostructures for integrated multi-element optomechanics
Sushanth Kini Manjeshwar, Karim Elkhouly, Jamie M. Fitzgerald +6
We present high-reflectivity mechanical resonators fabricated from AlGaAs heterostructures for use in free-space optical cavities operating in the telecom wavelength regime. The me…
Accurately heat flow distribution based on a triple quantum dot
Yanchao Zhang
We theoretically propose a simple setup based on a three terminal triple quantum dot in the Coulomb blockade regime as a heat flow allocator to spatially separate heat flows along…
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…
Thermometry based on Coulomb-coupled quantum dots
Yanchao Zhang, Jincan Chen
A theoretical proposal that Coulomb-coupled quantum dots can be used as quantum probes to determine the temperature of a sample (i.e., an electronic reservoir) is proposed. Through…
Coulomb-coupled quantum-dot thermal transistors
Yanchao Zhang, Zhimin Yang, Xin Zhang +3
A quantum-dot thermal transistor consisting of three Coulomb-coupled quantum dots coupled to respective electronic reservoirs by tunnel contacts is established. The heat flows thro…
