Experimental observation of energy-band Riemann surface
Dali Cheng, Heming Wang, Janet Zhong +3
Non-Hermiticity naturally arises in many physical systems that exchange energy with their environment. The presence of non-Hermiticity leads to many novel topological physics pheno…

Lorentz-Drude dipoles in the radiative limit and their modeling in finite-difference time-domain methods
Heming Wang, Shanhui Fan
The Lorentz-Drude model for electric dipoles is a classical framework widely used in the study of dipole dynamics and light-matter interactions. Here we focus on the behaviors of L…

Creating high-dimensional topological physics using a single ring resonator
Dali Cheng, Heming Wang, Charles Roques-Carmes +2
In spaces of three or more dimensions, there exists topological physics of significant richness that has no lower-dimensional counterparts. To experimentally explore high-dimension…
