标题： Testing Chern-Simons modified gravity with orbiting superconductive gravity gradiometers --- The non-dynamical formulation

摘要： 高精度超导重力梯度仪（SGG）是相对论实验的强大工具。 在本文中，我们推导了非动态Chern-Simons修正引力中的潮汐信号，这些信号可以通过围绕地球运行的SGG进行测量。 我们发现，通过适当定向多轴SGG，可以从不同轴的组合数据中分离出Chern-Simons修正的潮汐信号。 此外，对于三轴SGG，这种组合数据是总潮汐矩阵的迹，它在SGG轴旋转下保持不变，因此不受轴指向误差的影响。 沿着近圆形轨道，可以同时独立地测试破坏宇称的Chern-Simons修正以及测量保宇称度规理论中的引力磁性部分。 还包括对噪声源的初步分析。 显示英文摘要

摘要： High precision Superconductivity Gravity Gradiometers (SGG) are powerful tools for relativistic experiments. In this paper, we work out the tidal signals in non-dynamical Chern-Simons modified gravity, which could be measured by orbiting SGGs around Earth. We find that, with proper orientations of multi-axes SGGs, the tidal signals from the Chern-Simons modification can be isolated in the combined data of different axes. Furthermore, for three-axes SGGs, such combined data is the trace of the total tidal matrix, which is invariant under the rotations of SGG axes and thus free from axis pointing errors. Following nearly circular orbits, the tests of the parity-violating Chern-Simons modification and the measurements of the gravitomagnetic sector in parity-conserving metric theories can be carried out independently in the same time. A first step analysis on noise sources is also included.
