Free-electron Brewster radiation
Ruoxi Chen, Jialin Chen, Zheng Gong +7
Free-electron radiation offers an enticing route to create light emission at arbitrary spectral regime. However, this type of light emission is generally weak, which is intrinsical…
Non-Abelian nonsymmorphic chiral symmetries
Yi Yang, Hoi Chun Po, Vincent Liu +3
The Hofstadter model exemplifies a large class of physical systems characterized by particles hopping on a lattice immersed in a gauge field. Recent advancements on various synthet…
A general framework for scintillation in nanophotonics
Charles Roques-Carmes, Nicholas Rivera, Ali Ghorashi +12
Bombardment of materials by high-energy particles (e.g., electrons, nuclei, X- and -ray photons) often leads to light emission, known generally as scintillation. Scintillation i…
Observation of enhanced free-electron radiation from photonic flatband resonances
Yi Yang, Charles Roques-Carmes, Steven E. Kooi +6
Flatbands emerge from a myriad of structures such as Landau levels, Lieb and Kagome lattices, linegraphs, and more recently moire superlattices. They enable unique properties inclu…
A Brewster route to Cherenkov detectors
Xiao Lin, Hao Hu, Sajan Easo +10
The Cherenkov effect enables a valuable tool, known as the Cherenkov detector, to identify high-energy particles via the measurement of the Cherenkov cone. However, the sensitivity…
Three-dimensional non-Abelian generalizations of the Hofstadter model: spin-orbit-coupled butterfly trios
Vincent Liu, Yi Yang, John D. Joannopoulos +1
We theoretically introduce and study a three-dimensional Hofstadter model with linearly varying non-Abelian gauge potentials along all three dimensions. The model can be interprete…
