Revivals of photonic wavepackets induced by Curved Space |
Abstract: | We present the first study on the interplay between wave dynamics in lattices and the curvature of space, introducing General Relativity concepts to the rich physics of waves in periodic potentials. Our study describes these systems using the language of artificial gauge fields. We study phenomena associated with revivals of wavepackets induced by the curvature of space, and derive an analytical close-form condition for the revival of any wavepacket, regardless of its initial waveform. Our curved space system has unique features, which are fundamentally different from known revival phenomena in flat space. |
