| Applications of instantons to compute quantum-mechanical problems with spinless particles are shown. Effectivness and correctness of this method as a non-perturbative method is compared with the variational method applied to the potential of the triple-well shape. Limits of applicability of instanton solutions to compute energy of the ground state are also considered. |
