Query: Dissipative time crystal in an atom-cavity system: Influence of trap and
  competing interactions   While the recently realized dissipative time crystal in a laser-pumped
atom-cavity system in the experiment of Ke{\ss}ler et al. [Phys. Rev. Lett.
127, 043602 (2021)] is qualitatively consistent with a theoretical description
in an idealized limit, here, we investigate the stability of this dissipative
time crystal in the presence of an inhomogeneous potential provided by a
harmonic trap, and competing short- and infinite-range interactions. We note
that these features are ubiquitous in any realization of atom-cavity systems.
By mapping out the dynamical phase diagram and studying how it is modified by
the harmonic trap and short-range interactions, we demonstrate the persistence
of long-lived dissipative time crystals beyond the idealized limit. We show the
emergence of metastable dissipative time crystals with and without
prethermalization plateaus for tight harmonic confinement and strong contact
interaction, respectively.
