Photonic Metamaterial Time Crystals and Timetronics

Light-driven nonreciprocal forces in an array of nano-opto-mechanical oscillators can underpin the functionality of Time Crystal, a many-body interacting system that exhibits a spontaneous mobilization transition to the robust state of oscillation under an infinitely small change of the external driving force. Such time crystals are a form of Active Matter with life-mimicking dynamics accompanied by the breaking of time translation symmetry, ergodicity, and local entropy decrease. This is of interest to optical “timetronics” – a data processing and communications technology relying on the unique functionalities of time crystals.
