@article{Sarkar2022SignaturesOD, title={Signatures of discrete time-crystallinity in transport through an open Fermionic chain}, author={Subhajit Sarkar and Yonatan Dubi}, journal={Communications Physics}, year={2022}, volume={5}, pages={1-9} }

Discrete time-crystals are periodically driven quantum many-body systems with broken discrete time translational symmetry, a non-equilibrium steady state representing self-organization of motion of quantum particles. Observations of discrete time-crystalline order are currently limited to magneto-optical experiments and it was never observed in a transport experiment performed on systems connected to external electrodes. Here we demonstrate that both discrete time-crystal and quasi-crystal…
