从多体系统量子动力学推导立方非线性薛定谔方程

Derivation of the Cubic Non-linear Schrödinger Equation from Quantum Dynamics of Many-Body Systems

Laszlo Erdos, Benjamin Schlein, Horng-Tzer Yau

摘要:

严格证明了具有短尺度排斥对相互作用的三维相互作用玻色系统的单粒子密度矩阵在适当的标度极限下收敛于立方非线性薛定谔方程的解.将结果推广到所有正整数$k$的$k$ -粒子密度矩阵.

英文摘要:

We prove rigorously that the one-particle density matrix of three dimensional interacting Bose systems with a short-scale repulsive pair interaction converges to the solution of the cubic non-linear Schrödinger equation in a suitable scaling limit. The result is extended to $k$-particle density matrices for all positive integer $k$.
