    "abstract": "We investigate effects of staggered magnetic field on thermal entanglement in\nthe anisotropic XY model. The analytic results of entanglement for the two-site\ncases are obtained. For the general case of even sites, we show that when the\nanisotropic parameter is zero, the entanglement in the XY model with a\nstaggered magnetic field is the same as that with a uniform magnetic field.",
