在本文中,通过使用紧致性方法,我们研究了具有调和势的对数薛定格方程的柯西问题。然后,我们解决了基态解的存在性,作为 Nehari 流形上作用的最小化。最后,我们显式地计算了基态(高斯型解)并显示了它们的轨道稳定性。
In this paper, by using a compactness method, we study the Cauchy problem of the logarithmic Schr\"{o}dinger equation with harmonic potential. We then address the existence of ground states solutions as minimizers of the action on the Nehari manifold. Finally, we explicitly compute ground states (Gausson-type solution) and we show their orbital stability.
