Quantum thermal diode with additional control by auxiliary atomic states
Qin Zhang, Zi-chen Zhang, Yi-jia Yang +2
A quantum thermal diode, similar to an electronic diode, allows for unidirectional heat transmission. In this paper, we study a quantum thermal diode composed of two two-level atom…

Dual effects of Lamb Shift in Quantum Thermodynamical Systems
Zi-chen Zhang, Chang-shui Yu
The Lamb shift as an additional energy correction induced by environments usually has a marginal contribution and hence is neglected. We demonstrate that the Lamb shift, which modi…

The hidden negative differential thermal conductance
Zi-chen Zhang, Chang-shui Yu
Negative differential thermal conductance (NDTC), a hallmark of nonlinear quantum thermal transport, plays a critical role in the design of quantum thermal devices such as thermal…
