Non-Hermitian dynamics and $\mathcal{P}\mathcal{T}$-symmetry breaking in interacting mesoscopic Rydberg platforms

José A. S. Lourenço, Gerard Higgins, Chi Zhang +2

We simulate the dissipative dynamics of a mesoscopic system of long-range interacting particles which can be mapped into non-Hermitian spin models with a $\mathcal{P}\mathcal{T}$ symmetry. W…
