Two-Dimensional Topological Edge States in Periodic Space-Time Interfaces

Author(s): Ohad Segal, Yonatan Plotnik, Eran Lustig, Yonatan Sharabi, Moshe-Ishay Cohen, Alexander Dikopoltsev, and Mordechai Segev Topological edge states in systems of two (or more) dimensions offer scattering-free transport, exhibiting robustness to inhomogeneities and disorder. In a different domain, time-modulated systems, such as photonic time crystals, offer nonresonant amplification drawing energy from the modulation. Co… [Phys. Rev.
