Proposal for realizing Heisenberg-type quantum-spin models in Rydberg atom quantum simulators
ORAL
Abstract
We propose a method for experimentally realizing Heisenberg-type quantum-spin models in Rydberg-atom quantum simulators. In Rydberg-atom quantum simulators, the Heisenberg model has been realized experimentally using Floquet-engineering techniques [1,2]. In contrast to these works, our starting point is the XXZ model, which can be realized using a pair of Rydberg states, nS1/2 and (n+1)S1/2. We show that the anisotropy parameter of the XXZ model can be tuned by applying a uniform magnetic field and, in particular, that it changes drastically near the Forster resonance points [3]. We find that the spin-1/2 Heisenberg model can be realized for various parameters of alkali atoms. In addition, spin-1 Heisenberg-type quantum-spin models can also be realized in Rydberg-atom quantum simulators.
