Comment on failure of excited-state energy calculation of analytical transfer matrix method for the potential V(x) = 1/2 KX2 + λx4

Comment on failure of excited-state energy calculation of analytical transfer matrix method for the potential V(x) = 1/2 KX2 + λx4

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 substantia...
