Query: Signatures of discrete time-crystallinity in transport through quantum
  dot arrays   Discrete time-crystals are periodically driven quantum many-body systems with
broken discrete-time translational symmetry. Measurements of time-crystallinity
are currently limited to optical experiments due to the conception that the
presence of an environment destroys the time-crystal behavior. We demonstrate
that a periodically driven quantum dot array attached to electrodes exhibits
both stable and meta-stable discrete time-crystal and quasi-crystal behaviors.
These behaviors are manifested in spin-current measurable in transport set-up.
The present-day availability of quantum dot arrays with electrically
controllable sites makes our findings experimentally verifiable.
