中文摘要	we study the effects of the dzyaloshinski-moriya (dm) anisotropic interaction on the ground-state properties of the heisenberg xy spin chain by means of the fidelity susceptibility, order parameter, and entanglement entropy. our results show that the dm interaction could influence the distribution of the regions of quantum phase transitions and cause different critical regions in the xy spin model. meanwhile, the dm interaction has effective influence on the degree of entanglement of the system and could be used to increase the entanglement of the spin system.
