    "abstract": "The thermal entanglement of two spin-1 atoms with nonlinear couplings in\noptical lattices is investigated in this paper. It is found that the nonlinear\ncouplings favor the thermal entanglement creating. The dependence of the\nthermal entanglement in this system on the linear coupling, the nonlinear\ncoupling, the magnetic field and temperature is also presented. The results\nshow that the nonlinear couplings really change the feature of the thermal\nentanglement in the system, increasing the nonlinear coupling constant\nincreases the critical magnetic field and the threshold temperature.",
