On bound states of Schrödinger equation with vanishing magnetic potential
摘要
In this paper, we study the existence of a bound state solution for the stationary Schrödinger equation, which includes both a magnetic potential and an electric potential. Under certain assumption about the exponential decay of the combined magnetic and electric potentials, the existence of a least energy solution is established. Additionally, we provide a weaker sufficient condition for the existence of a bound state solution. Our approach is mainly based on the variational method.
