Optical parametric free-electron--photon quantum interaction
Zetao Xie, Zehai Pang, Yi Yang
Optical parametric processes underpin quantum photonics, while free-electron--photon interactions offer agile pathways to generate nontrivial quantum photonic states. These threads…

Topological quantum walk in synthetic non-Abelian gauge fields
Zehai Pang, Omar Abdelghani, Marin Soljačić +1
We theoretically introduce synthetic non-Abelian gauge fields for topological quantum walks. The photonic mesh lattice configuration is generalized with polarization multiplexing t…

Synthetic non-Abelian Electric Fields and Spin-Orbit Coupling in Photonic Synthetic Dimensions
Bengy Tsz Tsun Wong, Zehai Pang, Yi Yang
We theoretically propose a scheme to synthesize photonic non-Abelian electric field and spin-orbit coupling (SOC) in the synthetic frequency dimension based on a polarization-multi…
