用薛定谔方法超越单流
Beyond single-stream with the Schrödinger method
摘要：
在基于Vlasov-Poisson方程的相空间描述下，研究了无碰撞暗物质的大尺度结构形成。我们提出了薛定谔方法，最初由Widrow和Kaiser（1993）作为基于薛定谔泊松方程的数值技术，作为一种分析工具，它优于常见的标准无压流体模型。虽然尘埃模型失败，并在壳层交叉处产生奇点，但薛定谔方法包含多流甚至维里化。
英文摘要：
We investigate large scale structure formation of collisionless dark matter in the phase space description based on the Vlasov-Poisson equation. We present the Schrödinger method, originally proposed by Widrow and Kaiser (1993) as numerical technique based on the Schrödinger Poisson equation, as an analytical tool which is superior to the common standard pressureless fluid model. Whereas the dust model fails and develops singularities at shell crossing the Schrödinger method encompasses multi-streaming and even virialization.
