contents Neutral Rydberg atoms trapped in optical tweezer arrays provide a platform for quantum simulation and computation. In this work, we investigate the Lamb-Dicke dynamics of coupled Rydberg atoms for different trapping frequencies. We model the atomic motion by both internal and motional degrees of freedom, in which the motional states arise due to the oscillation of each atom in optical tweezer traps due to the light-atom interaction. In this setup, the internal states are coupled to a laser light with a Rabi frequency, while each internal state of each atom is also harmonically trapped with a trap frequency that depends on the internal state. The impact of the coherent motion of the optical tweezers on the collective dynamics of the many-body Rydberg atoms is explored for varying Lamb-Dicke parameters and with different trap frequencies. We see the occurrence of dynamical phases e.g., Rabi oscillations in the decoupled limit, the limit torus phase for magic trapping, and the limit cycle phase as the trap frequency is further increased.
