Abstract

The infinite time evolving block decimation in the presentation of infinite matrix product states based on machine learning is adopted to research a two-leg spin diagonal coupled setback ladder model. In order to deeply research the topological order and quantum phase transition of the model, odd string correlation and even string correlation are introduced, and the fidelity, local order parameters, odd string correlation and even string correlation order parameters are calculated. String correlations exhibit different behaviors. Based on the characteristics of the string correlation, the phase diagram of the ground state sequence parameters of the two-leg spin diagonal coupled setback ladder model is given. In addition, the results of phase transition point, continuous phase transition and order parameter detected by fidelity are consistent.
