Interplay of excitation hopping and electron-spin dynamics in Rydberg aggregates with spin-orbit coupling — •Karsten Leonhardt1, Sebastian Wüster1,2, and Jan-Michael Rost1 — 1Max Planck Institute for the Physics of Complex Systems — 2Indian Institute of Science Education and Research, Bhopal
Atoms became viable candidates of analog quantum simulators for condensed matter many-body Hamiltonians due to tremendous advances in cooling, trapping and selective manipulations. The key are (off)-resonant excitations to Rydberg states, which induce strong, long-range interactions whereby the atomic systems exhibit coherent dynamics between many-body states on mesoscopic time and length scales. So far the focus was on demonstrating implementations of Ising-type Hamiltonians [1,2] realized through van der Waals interactions of identical Rydberg (dressed) states, and, spin-exchange Hamiltonians realized through resonant dipole-dipole interactions between different Rydberg states [3,4]. Here we discuss implications arising from spin-orbit coupling, which enable the interplay of orbital angular momentum excitation hopping and electron-spin-flip dynamics.
