研究由N个全同玻色子组成的、兼具吸引两体与排斥三体相互作用的均匀二维玻色气体,借助哈特利理论推导其平均场极限对应的非线性薛定谔泛函,聚焦系统与两体相互作用的行为。
AI 中文摘要
我们考虑由N个全同玻色子组成的均匀玻色气体,其占据无限二维空间,该气体同时存在吸引两体相互作用与排斥三体相互作用。借助中间哈特利理论,我们严格推导了均匀三次-五次非线性薛定谔泛函,将其作为该模型的平均场极限,研究聚焦于系统与两体相互作用相关的行为。
英文摘要
We consider a homogeneous Bose gas composed of $N$ identical bosons occupying an infinite two-dimensional space. This gas exhibits both an attractive two-body interaction and a repulsive three-body interaction. Via the intermediate Hartree theory, we rigorously derive the homogeneous cubic-quintic nonlinear Schroedinger functional as the mean-field limit of the model. Our investigation focuses on the system's behavior in relation to the two-body interaction.
