报告摘要:This study investigates the 2-dimensional (2D) Gross-Pitaveskii-Poisson equations that model dipolar Bose-Einstein condensation. The new element introduced to these equations in this study is the construction of the modified cross-constrained minimization problem $\widetilde{d_{\mathcal{M}}}$ that is associated with the nonlocal kernel $\partial_{\mathbf{n}_{\perp} \mathbf{n}_{\perp}}-n_{3}^{2}\Delta$, resulting in the loss of $L^2$-norm scale invariance. We find modified cross-constrained manifolds and develop sharp criteria of blow-up and global existence as well as strong instability of standing waves. This work joint with Xiaoyu Zhou.
