论文摘要
标准模型扩展(SME)是一个有效的视野理论框架,可将所有洛伦兹侵入现场操作员分类。研究了从最低重力中小型中小型中小型中小型企业到牛顿重力能的各向异性校正,并通过扰动方法和数值方法来求解刚性球体的旋转。 Nordtvedt在参数化的Newtonian形式主义中给出的众所周知的强迫进液解决方案被回收,并应用于两个观察到的孤立毫秒脉冲星,以在SME框架中对lorentz违反的系数设定界限。研究了一种不同的解决方案,描述了在违反洛伦兹的情况下在存在洛伦兹的存在下旋转的,并且研究了其对由中子星(NSS)发出的脉冲星信号和连续重力波(GWS)的后果。一旦将来牢固地识别出免费的NSS,该研究提供了洛伦兹违规的新测试。
The Standard-Model Extension (SME) is an effective-field-theoretic framework that catalogs all Lorentz-violating field operators. The anisotropic correction from the minimal gravitational SME to Newtonian gravitational energy for spheroids is studied, and the rotation of rigid spheroids is solved with perturbation method and numerical approach. The well-known forced precession solution given by Nordtvedt in the parameterized post-Newtonian formalism is recovered and applied to two observed solitary millisecond pulsars to set bounds on the coefficients for Lorentz violation in the SME framework. A different solution, which describes the rotation of an otherwise free-precessing star in the presence of Lorentz violation, is found, and its consequences on pulsar signals and continuous gravitational waves (GWs) emitted by neutron stars (NSs) are investigated. The study provides new possible tests of Lorentz violation once free-precessing NSs are firmly identified in the future.
