We demonstrate a photonic analog of twisted bilayer graphene that has ultra-flat photonic bands and exhibits extreme slow light behavior. Our twisted bilayer photonic device, which has an operating wavelength in C-band of the telecom window, uses two crystalline silicon photonic crystal slabs ...
In quantum mechanics, wavefront dislocations have been predicted in connection to the Aharonov–Bohm effect8,9, and they have been observed recently in the electron density of graphene as a manifestation of the wave-function Berry phase10,11. In parallel, topology also spread in condensed matter...

In particular, the recent discovery of superconductivity in magic-angle twisted bilayer graphene [4] has triggered another wave of research in moiré 2D materials [5,6,7,8,9,10,11,12,13,14,15,16,17,18]. Twisted moiré photonic crystal is an optical analog of twisted 2D materials while ...
