量子玻色气体的平均场极限与非线性Hartree方程

Mean-Field Limit of Quantum Bose Gases and Nonlinear Hartree Equation

Juerg Froehlich, Enno Lenzmann

摘要:

我们讨论了Hartree方程中出现的大系统的玻色子的平均场极限,并解释其重要性的非线性薛定谔方程类。我们特别感兴趣的是Hartree方程与聚焦非线性(有吸引力的两体相互作用)。本文给出了Hartree方程的严格结果:(1)从大玻色子系统的量子理论导出的Hartree方程;(2)Hartree孤子的存在性和稳定性;(3)Hartree方程的点粒子(牛顿)极限。一些开放的问题进行了说明。

英文摘要:

We discuss the Hartree equation arising in the mean-field limit of large systems of bosons and explain its importance within the class of nonlinear Schroedinger equations. Of special interest to us is the Hartree equation with focusing nonlinearity (attractive two-body interactions). Rigorous results for the Hartree equation are presented concerning: 1) its derivation from the quantum theory of large systems of bosons, 2) existence and stability of Hartree solitons, and 3) its point-particle (Newtonian) limit. Some open problems are described.
