Ground-state energy eigenvalue calculation of the quantum mechanical well $V(x)={1/2}kx^{2}+λ{x^{4}}$ via analytical transfer matrix method
The analytical transfer matrix technique is applied to the Schrödinger equation of symmetric quartic-well potential problem in the form $V(x)={1/2}kx^{2}+λ{x^{4}}.$ This gives quantization condition from which we can calculate the ground-state energy eigenvalues numerically. We also compare the results with those obtained from numerical shooting method, perturbation theory, and WKB method.
