Rabi lattice models with discrete gauge symmetry: Phase diagram and implementation in trapped-ion quantum simulators
journal contribution
posted on 2023-06-08, 22:39 authored by Pedro Nevado, Diego PorrasWe study a spin-boson chain that exhibits a local Z2 symmetry. We investigate the quantum phase diagram of the model by means of perturbation theory, mean-field theory, and the density matrix renormalization group method. Our calculations show the existence of a first-order phase transition in the region where the boson quantum dynamics is slow compared to the spin-spin interactions. Our model can be implemented with trapped-ion quantum simulators, leading to a realization of minimal models showing local gauge invariance and first-order phase transitions.
