• Title: Entanglement generation in weakly-driven arrays of multilevel atoms via dipolar interactions
• Authors: Sanaa Agarwal, A. Piñeiro Orioli, J. K. Thompson, A. M. Rey,
• Abstract summary: We show that in the weakly driven low excitation regime, multilevel atoms, in contrast to two-level atoms, can become strongly entangled. The entanglement manifests as the growth of collective spin-waves in the ground state manifold, and survives even after turning off the drive.

• Abstract: We investigate the driven-dissipative dynamics of 1D and 2D arrays of multilevel atoms interacting via dipole-dipole interactions and trapped at subwavelength scales. Here we show that in the weakly driven low excitation regime, multilevel atoms, in contrast to two-level atoms, can become strongly entangled. The entanglement manifests as the growth of collective spin-waves in the ground state manifold, and survives even after turning off the drive. We propose to use the $\sim 2.9~\mu$m transition between $\rm ^3{\rm P}_2 \leftrightarrow \, ^3{\rm D}_3$ in $\rm ^{88}Sr$ with $\rm 389~nm$ trapping light as an ideal experimental platform for validating our predictions and as a novel quantum interface for the exploration of complex many-body phenomena emerging from light-matter interactions.
