相互作用玻色子系统多体哈密顿演化的先验估计

Apriori Estimates for Many-Body Hamiltonian Evolution of Interacting Boson System

Manoussos G. Grillakis, Dionisios Margetis

摘要:

研究了波函数服从玻色对称性下N体薛定谔方程的多粒子系统的演化。系统哈密顿量描述了在没有外部势的情况下两两粒子的相互作用。我们推导出先验色散估计,表示粒子相互作用的整体排斥性质。这些估计适用于与粒子数N无关的广泛的两体相互作用势。我们讨论了应用这些估计BBGKY层次的约化密度矩阵分析Elgart,鄂尔多斯,Schlein和丘。

英文摘要:

We study the evolution of a many-particle system whose wave function obeys the N-body Schroedinger equation under Bose symmetry. The system Hamiltonian describes pairwise particle interactions in the absence of an external potential. We derive apriori dispersive estimates that express the overall repulsive nature of the particle interactions. These estimates hold for a wide class of two-body interaction potentials which are independent of the particle number, N. We discuss applications of these estimates to the BBGKY hierarchy for reduced density matrices analyzed by Elgart, Erdos, Schlein and Yau.
