**Enhanced relaxation rate of atom counting statistics in weakly interacting Rydberg lattices** — •Wildan Abdussalam^{1}, Laura Gil^{1}, Igor Lesanovsky^{2}, and Thomas Pohl^{1} — ^{1}Max Planck Institute for the Physics and Complex Systems — ^{2}School of Physics and Astronomy, The University of Nottingham

We study the dynamics of spin lattices with power-law interactions driven by coherence laser-coupling under decoherence processes. We determine and analyse the atom counting statistics induced by dephasing, due to both homogeneous and inhomogeneous laser phase noises, via master equation and quantum stochastic methods. We find that the relaxation rate of atom counting statistics for the homogeneous laser noise increases when the weakly Rydberg-Rydberg interaction is applied. Meanwhile, the relaxation rate remains the same in the case of inhomogeneous laser noise.
