SYMMETRIC TRIPLE WELL WITH NON-EQUIVALENT VACUA: INSTANTONIC APPROACH

We show that for the triple well potential with non-equivalent vacua, instantons generate for the low lying energy states a singlet and a doublet of states rather than a triplet of equal energy spacing. Our energy splitting formulas are also confirmed numerically. This splitting property is due to t...

Zusammenfassung:We show that for the triple well potential with non-equivalent vacua, instantons generate for the low lying energy states a singlet and a doublet of states rather than a triplet of equal energy spacing. Our energy splitting formulas are also confirmed numerically. This splitting property is due to the presence of non-equivalent vacua. A comment on its generality to multi-well is presented.
