STABILITY OF STANDING WAVES FOR A NONLINEAR SCHRÖDINGER EQUATION UNDER AN EXTERNAL MAGNETIC FIELD.

In this paper we study the existence and orbital stability of ground states for logarithmic Schrödinger equation under a constant magnetic field. For this purpose we establish the well-posedness of the Cauchy Problem in a magnetic Sobolev space and an appropriate Orlicz space. Then we show the existence of ground state solutions via a constrained minimization on the Nehari manifold. We also show that the ground state is orbitally stable. [ABSTRACT FROM AUTHOR]
