Oleg Asipchuk, Christopher Leonard, Shijun Zheng

AI总结:

本文研究一类无界电磁势下 L^2-临界磁非线性薛定谔方程,证明了基态解的存在性与稳定性,并通过构造涡旋型函数给出各向异性调和势下的非存在性结果,推广了已有工作并补充了数值实验。

摘要:

对于一类无界电磁势,我们证明了 L^2-临界磁非线性薛定谔方程(mNLS)基态解(g.s.s.)的存在性与稳定性。随后,通过在具有各向异性调和势的 RNLS 背景下构造一列涡旋型函数,我们给出了非存在性结果。这些结果推广了文献 [3] 和 [20] 中的相应结论。旋转 NLS 在各向同性调和势下的情形最近已在文献 [10] 中得到处理。本文还包含了阈值附近基态轮廓的数值结果。

英文摘要:

We show the existence and stability of ground state solutions (g.s.s.) for $L^2$-critical magnetic nonlinear Schrödinger equations (mNLS) for a class of unbounded electromagnetic potentials. We then give non-existence result by constructing a sequence of vortex type functions in the setting of RNLS with an anisotropic harmonic potential. These generalize the corresponding results in [3] and [20]. The case of an isotropic harmonic potential for rotational NLS has been recently addressed in [10]. Numerical results on the ground state profile near the threshold are also included.
