Plasmonic Time Crystals
Joshua Feinberg, David E. Fernandes, Boris Shapiro +1
We study plasmonic time crystals, an extension of dielectric-based photonic time crystals to plasmonic media. Remarkably, we demonstrate that such systems may amplify both longitud…

Longitudinal optical phonons in photonic time crystals containing a stationary charge
Sihao Zhang, Junhua Dong, Huanan Li +2
Lorentzian-type media support optical phonons that oscillate with longitudinal polarization parallel to the wave direction, at a wave vector-independent frequency at which the perm…
