AbstractQuantum many-body scars are notable as nonthermal, low-entanglement states that exist at high energies. Here, we use attractively interacting dysprosium gases to create scar states that are stable enough to be driven into a strongly nonlinear regime while retaining their character. We measure how the kinetic and total energies evolve after quenching the confining potential.

Abstract We explore the effect of tunable integrability-breaking dipole-dipole interactions in the equilibrium states of highly magnetic one-dimensional (1D) Bose gases of dysprosium at low temperatures. We experimentally observe that in the strongly correlated Tonks-Girardeau regime, rapidity and momentum distributions are nearly unaffected by the dipolar interactions.
