Interlocked Time Crystal in Coupled Spin-1/2 Ensembles under Local Dissipation
Zhen-Huan Yang, Zhen-Tao Liang, Dan-Bo Zhang
The paper shows that coupling two spin‑½ ensembles with opposite pumping and decay can generate a synchronized, non‑equilibrium time‑crystalline phase, even though each ensemble al…

Spontaneous Macroscopic Quantum Synchronization in an Ensemble of Two-level Systems
Zhen-huan Yang, Dan-Bo Zhang
Spontaneous macroscopic quantum synchronization is an emergent phenomenon where an ensemble of quantum oscillators achieves global phase coherence through the interplay of interact…
