The Critical Behavior of Quantum Stirling Heat Engine
Yuan-Sheng Wang, Man-Hong Yung, Dazhi Xu +2
We investigate the performance of a Stirling cycle with a working substance (WS) modeled as the quantum Rabi model (QRM), exploring the impact of criticality on its efficiency. Our…
Coherence-Assisted Superradiant Laser with Hz Linewidth and W Power
Guohui Dong, Yao Yao, Peng Zhang +1
The superradiant laser, based on the clock transition between the electric ground state S and the metastable state P of fermionic alkaline-earth(-like) atoms, has b…
Efficient measurement of the time-dependent cavity field through compressed sensing
Fang Zhao, Qing Zhao, Dazhi Xu
We propose a method based on compressed sensing (CS) to measure the evolution processes of the states of a driven cavity quantum electrodynamics system. In precisely reconstructing…
Quantum theory of photonic vortices and quantum statistics of twisted photons
Li-Ping Yang, Dazhi Xu
The topological charge of a photonic vortex is an essential quantity in singular optics and the critical parameter to characterize the vorticity of twisted light. However, the defi…
Nonadiabatic evolution and thermodynamics of a time-dependent open quantum system
Dan Wang, Dazhi Xu
We investigate the dynamic evolution and thermodynamic process of a driven quantum system immersed in a finite-temperature heat bath. A Born-Markovian quantum master equation is fo…
Magnetically Induced Optical Transparency With Ultra-Narrow Spectrum
Guohui Dong, Dazhi Xu, Peng Zhang
Magnetically induced optical transparency (MIOT) is a technique to realize the narrow transmission spectrum in a cavity quantum electric dynamics (cavity QED) system, which is demo…
