Emergent synchronization mode in coupled Rydberg atomic chains

Weilun Jiang·Nov 15, 2025

We report a new oscillatory form in the two coupled dissipative Rydberg atomic chains by modulating its spacing. Such oscillation has $π$-phase difference between two neighboring sites, which distinguishes itself from antiferromagnetic-type synchroni...
