Quantum systems with multiple degenerate classical harmonic minima exhibit new non-perturbative phenomena which are not present for the double-well and periodic potentials. The simplest characteristic example of this family is the triple-well potenti... Read More about Bions and Instantons in Triple-well and Multi-well Potentials.
