Query: Discrete time crystal in globally driven interacting quantum systems
  without disorder   Time crystals in periodically driven systems have initially been studied
assuming either the ability to quench the Hamiltonian between different
many-body regimes, the presence of disorder or long-range interactions. Here we
propose the simplest scheme to observe discrete time crystal dynamics in a
one-dimensional driven quantum system of the Ising type with short-range
interactions and no disorder. The system is subject only to a periodic kick by
a global magnetic field, and no extra Hamiltonian quenching is performed. We
analyze the emerging time crystal stabilizing mechanisms via extensive numerics
as well as using an analytic approach based on an off-resonant transition
model. Due to the simplicity of the driven Ising model, our proposal can be
implemented with current experimental platforms including trapped ions, Rydberg
atoms, and superconducting circuits.
