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…
