Photonic Time-Crystals
Photonic Time-Crystals (PTCs) are materials in which the refractive index varies periodically and abruptly in time. They conserve momentum but not energy, and display momentum bands separated by gaps. The fundamentals of PTCs will be presented, with an emphasis on light-matter interactions ranging from light emission by atoms and free electrons to superluminal k-gap solitons and recent experiments on time-refraction at optical frequencies.
