具有各向异性可切换二次型陷阱的二维三次非线性薛定谔方程的坍缩估计和严格推导

Collapsing Estimates and the Rigorous Derivation of the 2d Cubic Nonlinear Schrödinger Equation with Anisotropic Switchable Quadratic Traps

Xuwen Chen

摘要:

本文研究了各向异性可开关二次型势阱下的二维和三维多体薛定谔方程。我们推广并改进了Klainerman-Machedon [24]和Kirkpatrick-Schlein-Staffilani [23]中的塌缩估计。结合Carles [3]中广义透镜变换的各向异性版本,我们通过修改的Elgart-Erdös-Schlein-Yau过程严格推导了具有各向异性可切换二次陷阱的2d立方NLS。对于3D的情况下,我们建立了相应的Gross-Pitaevskii层次的唯一性,而无需假设的因式分解的初始数据。

英文摘要:

We consider the 2d and 3d many body Schrödinger equations in the presence of anisotropic switchable quadratic traps. We extend and improve the collapsing estimates in Klainerman-Machedon [24] and Kirkpatrick-Schlein-Staffilani [23]. Together with an anisotropic version of the generalized lens transform in Carles [3], we derive rigorously the cubic NLS with anisotropic switchable quadratic traps in 2d through a modified Elgart-Erdös-Schlein-Yau procedure. For the 3d case, we establish the uniqueness of the corresponding Gross-Pitaevskii hierarchy without the assumption of factorized initial data.
