energy level statistics in Rydberg Composites — •Andrew Hunter, Matthew Eiles, Alex Eisfeld, and Jan M Rost — Max Planck Institute for the Physics of Complex Systems

Rydberg Composites are a new class of Rydberg matter consisting of a single Rydberg atom interfaced with a dense environment of neutral ground state atoms organized in a lattice [1]. The properties of the Rydberg composite are directly linked to the discrete symmetry of the occupied sites in the lattice with characteristic but unusual footprints of quantum chaos in the energy level statistics of the composite. We have developed techniques to identify these effects and present a systematic study of broken lattice symmetry and the transition to full chaos as atoms are removed from the lattice. We also describe how these statistics change with decreasing lattice constant with a transition to a continuous environment when the Rydberg electron can no longer resolve the lattice spacing.
