Introduction to Semiclassical Methods for the Schrödinger Operator with a Large Electric Potential
In this chapter, we present one of the basic techniques for analyzing the ground state energy (also called lowest eigenvalue or principal eigenvalue) of a Schrödinger operator in the case when the electric potential V has nondegenerate minima, in the limit of large coupling constant B. This problem turns out to be a semiclassical problem.
