我们考虑Gross-Pitaevskii方程的半经典极限。为了考虑无穷远处的非平凡边界条件,我们在Zhidkov空间而不是Sobolev空间中工作。对于通常的三次非线性,我们得到了当普朗克常数趋于零时波函数的点向描述,只要极限系统中不出现奇点。对于三次五次非线性,我们证明了用解析数据处理可能是得到类似结果的必要和充分条件。©2008 Elsevier Masson SAS。版权所有。
We consider the semi-classical limit for the Gross–Pitaevskii equation. In order to consider non-trivial boundary conditions at infinity, we work in Zhidkov spaces rather than in Sobolev spaces. For the usual cubic nonlinearity, we obtain a point-wise description of the wave function as the Planck constant goes to zero, so long as no singularity appears in the limit system. For a cubic-quintic nonlinearity, we show that working with analytic data may be necessary and sufficient to obtain a similar result.© 2008 Elsevier Masson SAS. All rights reserved.
