Simulation of Dynamical Quantum Phase Transition of the 1D Transverse Ising Model with a Double-chain Bose-Hubbard model (2003.02411v2)

Abstract: We propose a spinless Bose-Hubbard model in an one-dimensional (1D) double-chain tilted lattice at unit filling per cell. A subspace of this model can be faithfully mapped to the 1D transverse Ising model through superexchange interaction with second-order perturbation theory. At a valid parameter region, numerical results show good agreement of these two models both on energy spectrums and correlation functions. And we show that the dynamical quantum phase transition of the effective 1D transverse Ising model can be simulated. With carefully designed procedures for producing the dynamical quantum phase transition of the 1D transverse Ising model from a Mott insulator, the rate function of the recurrence probability to the ground-state manifold shows the same nonanalyticality at periodic time points as theory predicts. Our results may give some inspirations on simulating 1D transverse Ising model with superexchange interaction and exploring its dynamical quantum phase transition in experiment.
