论文摘要
三明治引力波在边界处的步骤函数在全球范围内给出。线性化的爱因斯坦 - 韦尔方程在Rosen坐标中精确求解。根据三明治波的几何形状和组成,中微子的能量摩孔本身会重新分配。在测试场水平上,由于背景不会改变,因此中微子的能量密度尤其会显示出越过三明治波时正极和负极的变化。这可能揭示了有关宇宙学中弱相互作用中微子的事实。
Sandwich gravitational waves are given globally in terms of step functions at the boundaries. Linearized Einstein-Weyl equations are solved exactly in this background in Rosen coordinates. Depending on the geometry and composition of the sandwich wave, the neutrino's energy-momentum redistributes itself. At the test field level, since the background will not change, the neutrino's energy density in particular will show variations between positive and negative extrema when crossing the sandwich wave. This may reveal facts about the weakly interacting neutrinos in cosmology.
