- Abstract: We simulate the dynamics of Rydberg atoms resonantly exchanging energy via
two-, three-, and four-body dipole-dipole interactions in a one-dimensional
array. Using a simplified model of a realistic experimental system, we study
the initial state survival probability, the level spacing statistics, the
spread of entanglement, and the properties of the energy eigenstates. By
exploring a range of disorders and interaction strengths, we find regions in
parameter space where the three- and four-body dynamics exhibit nonergodic
behavior and either fail to reach thermodynamic equilibrium or do so slowly.
The interplay between the hopping and field-tuned interactions gives rise to
quantum many-body scar states, which play a critical role in slowing the
dynamics of the three- and four-body interactions.
