Prethermal Time Crystals in Holographic Systems

This paper explores the emergence of prethermal time crystals in a hybrid quantum system, offering a novel perspective on time crystal behavior without fine-tuning. The study leverages a semi-holographic approach, connecting a perturbative sector with holographic degrees of freedom. The findings suggest that these time crystals can be observed through specific operator measurements and that black holes with planar horizons can exhibit both inhomogeneous and metastable time crystal phases. The work also hints at the potential for realizing such phases in non-Abelian plasmas.
