Acceleration of Free Electrons by Photonic Time-Crystals
Lior Bar-Hillel, Alexey Gorlach, Ido Kaminer +1
We study the quantum interaction between free electrons and photons in a time-varying media, and find that periodic modulation exponentially amplifies electron-photon coupling with…

Long lived surface plasmons on the interface of a metal and a photonic time-crystal
Lior Bar-Hillel, Yonatan Plotnik, Ohad Segal +1
We predict the existence of surface plasmons polaritons at the interface between a metal and a periodically modulated dielectric medium, and find an unusual multi-branched dispersi…

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…
