2D Topological Edge States in Periodic Space-Time Interfaces
Ohad Segal, Yonatan Plotnik, Eran Lustig +4
Topological edge states in systems of two (or more) dimensions offer scattering-free transport, exhibiting robustness to inhomogeneities and disorder. In a different domain, time-m…

Time-refraction and time-reflection above critical angle for total internal reflection
Lior Bar-Hillel, Alex Dikopoltsev, Amit Kam +4
We study the time-reflection and time-refraction of waves caused by a spatial interface with a medium undergoing a sudden temporal change in permittivity. We show that monochromati…

Topology of photonic time-crystals
Eran Lustig, Yonatan Sharabi, Mordechai Segev
We introduce topological phases in Photonic Time-Crystals. Photonic Time-Crystals are materials in which the refractive index varies periodically and abruptly in time. When the ref…
