Laszlo Erdos, Horng-Tzer Yau

摘要:

本文研究了N玻色粒子通过平均场库仑势相互作用的时间演化。假设初始状态是一个乘积波函数。我们表明,在任何有限时间的关联函数分解的限制$N \to \infty$。此外,极限单粒子密度矩阵满足非线性Hartree方程.关键的成分是关联函数的BBGKY族的唯一性和一个新的先验估计的多体薛定谔方程。

英文摘要:

We consider the time evolution of N bosonic particles interacting via a mean field Coulomb potential. Suppose the initial state is a product wavefunction. We show that at any finite time the correlation functions factorize in the limit $N \to \infty$. Furthermore, the limiting one particle density matrix satisfies the nonlinear Hartree equation. The key ingredients are the uniqueness of the BBGKY hierarchy for the correlation functions and a new apriori estimate for the many-body Schrödinger equations.
