R. R. Cuzinatto, P. J. Pompeia, M. de Montigny, F. C. Khanna

摘要:

在$(4+1)$维伽利略框架下研究了具有一般协变性的局部伽利略不变引力理论的弱场近似。额外的自由度使我们能够得到波动场的泊松方程、扩散方程和薛定谔方程。与通常的$(3+1)$维广义相对论相比,这种方法的一个优点是,它允许我们选择一个可以容纳拉格朗日方法的场方程的波动场,以修改牛顿动力学(MOND),称为水拉格朗日(AQUAL)。本文研究了薛定谔方程的波动解。

英文摘要:

We examine the weak-field approximation of locally Galilean invariant gravitational theories with general covariance in a $(4+1)$-dimensional Galilean framework. The additional degrees of freedom allow us to obtain Poisson, diffusion, and Schrödinger equations for the fluctuation field. An advantage of this approach over the usual $(3+1)$-dimensional General Relativity is that it allows us to choose an ansatz for the fluctuation field that can accommodate the field equations of the Lagrangian approach to MOdified Newtonian Dynamics (MOND) known as AQUAdratic Lagrangian (AQUAL). We investigate a wave solution for the Schrödinger equations.
