摘要
We investigate a four-parameter class of quasi-exactly solvable double-well potentials. We present an analytical solution for this class of double-well potentials in terms of the confluent Heun functions. It is shown that under specific values of the potential parameters, certain eigenenergies and eigenfunctions can be found exactly in an explicit form. In addition, these exact analytical solutions are used to construct exact localized solutions for the nonlinear Schrodinger equation with a double-well self-defocusing nonlinearity.
