Discrete Time Crystals in the spin-s Central Spin Model
Hillol Biswas, Sayan Choudhury
We propose periodic driving protocols to realize discrete time crystals (DTCs) in a spin-s central spin model. Interestingly, we identify parameter regimes, where eternal period-do…

The Floquet central spin model: A platform to realize eternal time crystals, entanglement steering, and multiparameter metrology
Hillol Biswas, Sayan Choudhury
We propose and characterize protocols to engineer exact quantum revivals, discrete time crystals (DTCs), and entanglement oscillations in the periodically driven central spin model…
