非线性有质量引力理论中的单极子解

近年来，非线性有质量引力理论引起了广泛的关注．它不仅能在小尺度上屏蔽第五种力，又能在大尺度上引起宇宙的加速膨胀．另一方面，引力场与Kalb—Ramond场耦合具有单极子解．这使得洛伦兹破缺具有了可观测效应．本研究计算了非线性有质量引力与Kalb．Ramond场耦合的情形，结果与广义相对论的结果大不相同．在外部解无法回到广义相对论情形，且其形式与Schwazchild度规很相似．这使得光线偏转效应被大大的降低了．

The monopole solution in nonlinear massive gravity

Recently, nonlinear massive gravity is under discussed. Nonlinear massive gravity can not only screen the fifth force on small distance, but also make acceleration on cosmological scales. On the other hand, there exsits monopole solutions in the mini- mal model coupled to Einstein gravity for Kalb-Ramond field. We can use this method to test Lorentz symmetry breaking. This pa- per calculates the solution of nonlinear massive gravity coupled to Kalb-Ramond field. We find it is different from the situation of Einstein gravity coupled Kalb-Ramond field. The solution cannot reproduce general gravity solution in the massless limit, and it is in the similitude of the Schwazchild which lowers the departure of ray.
