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…
Topological nature of non-Hermitian degenerate bands in structural parameter space
Olivia Y. Long, Cheng Guo, Shanhui Fan
In photonics, band degeneracies at high-symmetry points in wavevector space have been shown to exhibit rich physical phenomena. However, obtaining degenerate bands away from such p…
Tunable Magnetless Optical Isolation with Twisted Weyl Semimetals
Vladislav Chistyakov, Viktar S. Asadchy, Shanhui Fan +2
Weyl semimetals hold great promise in revolutionizing nonreciprocal optical components due to their unique topological properties. By exhibiting nonreciprocal magneto-optical effec…
Universal and ultrafast quantum computation based on free-electron-polariton blockade
Aviv Karnieli, Shai Tsesses, Renwen Yu +4
Cavity quantum electrodynamics (QED), wherein a quantum emitter is coupled to electromagnetic cavity modes, is a powerful platform for implementing quantum sensors, memories, and n…
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…
On-chip optical twisted bilayer photonic crystal
Haoning Tang, Beicheng Lou, Fan Du +6
Recently, moiré engineering has been extensively employed for creating and studying novel electronic materials in two dimensions. However, its application in nanophotonic systems h…
