Simulating quantum Ising dynamics on Rydberg atom chain

Neutral atom array trapped in programmable optical tweezers with tunable interactions emerges as a promising quantum simulation platform for various quantum phenomenon, such as quantum phase transition, Kibble-Zurek mechanism, quantum spin liquid, and quantum many-body scars, etc. We investigate the low energy excitation and the dynamics in one-dimensional Rydberg atom chain with tuned Hamiltonians. In the region near or away from the critical point, interesting properties of emergent quasiparticle can be benchmarked with analytical and numerical simulations. Our research shows potential advantage in simulating many body dynamics with neutral atom simulator.
