Аннотация
The analytical transfer matrix method is applied to the quantum mechanical bound-state problem potential with V(x) = (1/2)kx 2 + λx 4. It is found that numerical values of phase contribution are unstable when compared with standard methods like numerical WKB approximation, this leads to substantial errors in excited-state energy calculation.
