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…

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…

Non-Abelian lattice gauge fields in the photonic synthetic frequency dimension
Dali Cheng, Kai Wang, Charles Roques-Carmes +4
Non-Abelian gauge fields provide a conceptual framework for the description of particles having spins. The theoretical importance of non-Abelian gauge fields motivates their experi…
