Single-particle localization in a two-dimensional Rydberg spin system

We study excitation transport in a two-dimensional system of randomly assembled spins with power-law hopping in two dimensions. This model can be realized in cold atom quantum simulators with Rydberg atoms. In these experiments, due to the Rydberg …

Glassy quantum dynamics of disordered Ising spins

We study out-of-equilibrium dynamics in the quantum Ising model with power-law interactions and positional disorder. For arbitrary dimension d and interaction range α≥d we analytically find a stretched exponential decay with stretch power β=d/α for …

Nonlinear absorption in interacting Rydberg EIT spectra on two-photon resonance

We experimentally investigate the nonlinear transmission spectrum of coherent light fields propagating through a Rydberg-EIT medium with strong atomic interactions. In contrast to previous investigations, which have largely focused on resonant …
