Eigenenergy braids in 2D photonic crystals
Janet Zhong, Charles C. Wojcik, Dali Cheng +1
We consider non-Hermitian energy band theory in two-dimensional systems, and study eigenenergy braids on slices in the two-dimensional Brillouin zone. We show the consequences of r…

Multi-dimensional band structure spectroscopy in the synthetic frequency dimension
Dali Cheng, Eran Lustig, Kai Wang +1
The concept of synthetic dimensions in photonics provides a versatile platform in exploring multi-dimensional physics. Many of these physics are characterized by band structures in…
