不同条件下Mathisson方程的公共解

On common solutions of Mathisson equations under different conditions

Roman Plyatsko, Oleksandr Stefanyshyn

摘要:

在研究自旋粒子在引力场中可能的高度相对论性运动的背景下,我们分析了史瓦西场中的圆轨道,这些运动可以用Mathisson方程在不同的补充条件下描述。这些轨道最清楚地表明了引力自旋轨道相互作用对粒子运动的影响。结果表明,在Frenkel-Mathisson和Tulczynge-Dixon条件下的Mathisson方程在$r=3M(1+δ), |δ|\ll 1$区域具有描述高度相对论性圆轨道的公共解.这些轨道本质上不同于同一区域的测地线圆轨道,特别是粒子在相应轨道上的能量值。

英文摘要:

In the context of investigations of possible highly relativistic motions of a spinning particle in the gravitational field, which can be described by the Mathisson equations under different supplementary condition, we analyze the circular orbits in a Schwarzschild field. The very orbits most clearly demonstrate the effect of the gravitational spin-orbit interaction on the particle's motion. It is shown that the Mathisson equations under the Frenkel-Mathisson and Tulczyjew-Dixon conditions have the common solutions describing the highly relativistic circular orbits in the region $r=3M(1+δ), |δ|\ll 1$. These orbits essentially differ from the geodesic circular orbits in the same region, particularly by the value of the particle's energy on the corresponding orbits.
