  • CREOL Special Colloquium: Dr. Moti Segev - Photonic Time-Crystals

    CREOL: 102 and Virtual

    Abstract: Photonic Time Crystals (PTCs) are dielectric media whose refractive index is modulated periodically in time at time scales of an optical cycle. These systems conserve momentum but not energy, and are characterized by momentum bands and bandgaps, where the amplitudes of their eigenmodes can increase (or decrease) exponentially. I will introduce the fundamentals of PTCs, discuss the topological features …
