Discrete Time Crystals — •Roderich Moessner — MPI-PKS, Dresden, Germany

Periodically driven ("Floquet") systems provide perhaps the simplest setting for studying quantum systems out of equilibrium. Their properties have turned out to be remarkably rich. In particular, the interplay of disorder and driving has given rise to an entirely new form of spatio-temporal ordering which has been given the name discrete time crystal.

This talk presents an introduction to the physics of Floquet systems and explains how non-equilibrium phases and their concomitant ordering arise.

This work was done in collaboration with Achilleas Lazarides, Arnab Das, Vedika Khemani, and Shivaji Sondhi. For an introductory review, see Nature Physics 13, 424-428 (2017).
