Stability of standing waves for logarithmic Schrödinger equation with attractive delta potential

preprint2016arXivOpen access

Abstract

We consider the one-dimensional logarithmic Schrödinger equation with a delta potential. Global well-posedness is verified for the Cauchy problem in H1(R) and in an appropriate Orlicz space. In the attractive case, we prove orbital stability of the ground states via variational approach.
