Supersymmetric modified Airy-function method and its application to the Schrödinger potential V(x) = x6 − 3x2
Tóm tắt
A supersymmetric version of the modified Airy-function method is developed. Explicit calculations for eigenvalues are obtained for the Schrödinger potential V(x) = x6 − 3x2. Comparison is made with exact numerical results as well as those of the Wentzel–Kramers–Brillouin (WKB), supersymmetric WKB (SWKB), and modified Airy-function approximation methods.
