薛定谔-泊松方程的线性牛顿微扰理论
Linear Newtonian perturbation theory from the Schrödinger-Poisson equations
摘要:
我们得到的耦合薛定谔-泊松方程的解决方案。这些解描述了在均匀膨胀的弗里德曼宇宙中冷暗物质密度扰动的演化。我们讨论了冷暗物质的无压流体,在一个波函数,一个经典的标量场,和量子标量场的描述之间的关系。我们确定的制度,在各种描述一致,他们不同。
英文摘要:
We obtain solutions to the coupled Schrödinger-Poisson equations. The solutions describe the evolution of cold dark matter density perturbations in an otherwise homogeneous expanding Friedmann universe. We discuss the relationships between descriptions of cold dark matter in terms of a pressureless fluid, in terms of a wavefunction, of a classical scalar field, and a quantum scalar field. We identify the regimes where the various descriptions coincide and where they differ.
