Quantum correlations of localized atomic excitations in a disordered atomic chain

The atom-waveguide interface mediates significant and long-range light-matter interactions through guided modes. In this one-dimensional system, we theoretically investigate the excitation localization of multiple atomic excitations under strong position disorder. Deep in side, obtain time evolutions quantum correlations via Kubo cumulant expansions, which arise initially become finite leveled afterward, overtaking those without This indicates two distinct regimes time: before onset localization, disorder engage disturbance correlations, is followed by disorder-assisted buildup that maintain at a later stage owing to absence diffusion. crossing pushed further for longer-range characteristic timescale needed sustain them. We also explore effect directionality couplings resonant dipole-dipole interactions, can drive system toward delocalized side when it chiral or large interaction strengths. time-evolved give insights into studies few-body phenomenon nonequilibrium dynamics open systems.
