Aspects of quantum geometry in photonic time crystals
Karthik Subramaniam Eswaran, Ali Emami Kopaei, Krzysztof Sacha
We develop a geometric description of quantum light in photonic time crystals on the SU(1,1) coherent-state manifold. In a projective picture, the evolution of each mode appears as…
Towards Timetronics with Photonic Systems
Ali Emami Kopaei, Karthik Subramaniam Eswaran, Arkadiusz Kosior +5
Periodic driving of particles can create crystalline structures in their dynamics. Such systems can be used to study solid-state physics phenomena in the time domain. In addition,…
Anderson Localization in Photonic Time Crystals
Karthik Subramaniam Eswaran, Ali Emami Kopaei, Krzysztof Sacha
Solutions of the wave equations for time-independent disordered media can exhibit Anderson localization where instead of wave propagation we observe their localization around diffe…
Temporal localization of optical waves supported by a copropagating quasiperiodic structure
Majid Yazdani-Kachoei, Krzysztof Sacha, Boris A. Malomed
Research on time crystals concerns the spontaneous breaking of translational symmetry in time, as well as the realization of phenomena and phases known from solid-state physics in…
