Introduction
You can think of this Chapter as a renement of what you have learned already.
It is a quite beautiful (and useful!) renement.
In many problems the actual dynamics of a system are not completely kn

Three-Well System
A potential with three wells in sequence connes a physical object to exist in a combination of three
discrete states. The energy for this system includes self energy E0 , as well as energy from interaction
between nea
