五次NLS作为三体相互作用玻色子气体的平均场极限

The quintic NLS as the mean field limit of a Boson gas with three-body interactions

Thomas Chen, Nataša Pavlović

摘要:

本文研究了$d=1,2$维中具有三体相互作用的玻色子气体的动力学。我们证明了在无限粒子数的极限下,$k$ -粒子边缘的BBGKY族收敛到一个极限(Gross-Pitaevskii(GP))族,并证明了解的存在唯一性. GP族的因式分解的解决方案被证明是由一个五次非线性薛定谔方程的解决方案。我们的证明是基于和扩展的方法Erdös-Schlein-Yau,Klainerman-Machedon和Kirkpatrick-Schlein-Staffilani。

英文摘要:

We investigate the dynamics of a boson gas with three-body interactions in dimensions $d=1,2$. We prove that in the limit of infinite particle number, the BBGKY hierarchy of $k$-particle marginals converges to a limiting (Gross-Pitaevskii (GP)) hierarchy for which we prove existence and uniqueness of solutions. Factorized solutions of the GP hierarchy are shown to be determined by solutions of a quintic nonlinear Schrödinger equation. Our proof is based on, and extends, methods of Erdös-Schlein-Yau, Klainerman-Machedon, and Kirkpatrick-Schlein-Staffilani.
