Non-Hermitian dynamics and PT-symmetry breaking in interacting mesoscopic Rydberg platforms
The study simulates long-range interacting particles mapped onto non-Hermitian spin models exhibiting $\mathcal{PT}$ symmetry. The research reveals rich $\mathcal{PT}$-phase diagrams containing both symmetric and broken phases. Long-range interactions enable new $\mathcal{PT}$-symmetric regions, leading to novel phase transitions when system parameters are varied.
