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…
The field induced magnetic dipolar interaction for general boundary conditions
Sheng-Wen Li, Li-Ping Yang
By properly considering the propagation dynamics of the dipole field, we obtain the full magnetic dipolar interaction between two quantum dipoles for general situations. With the h…
Duality Symmetry of Quantum Electrodynamics and Magnetic Charges
Li-Ping Yang, Dazhi Xu
The duality symmetry between electricity and magnetism hidden in classical Maxwell equations suggests the existence of dual charges, which have usually been interpreted as magnetic…
Quantum sensing of photonic spin density
Farid Kalhor, Li-Ping Yang, Leif Bauer +1
Photonic spin density (PSD) in the near-field gives rise to exotic phenomena such as photonic skyrmions, optical spin-momentum locking and unidirectional topological edge waves. Ex…
