Bpst instanton
In studying quantum field theory (QFT), the vacuum structure of a theory may draw attention to instantons. Just as a double-well quantum mechanical system illustrates, a naïve vacuum may not be the true vacuum of a field theory. Moreover, the true vacuum of a field theory may be an "overlap" of several topologically inequivalent sectors, so called "topological vacua". A well understood and illustrative example of an instanton and its interpretation can be found in … WebOne can imagine an instanton with index to quantify tunneling between topological vacua and . If Q = 1, the configuration is named BPST instanton after its discoverers Alexander Belavin, Alexander Polyakov, Albert S. Schwartz and Yu. S. Tyupkin. The true vacuum of the theory is labelled by an "angle" theta and is an overlap of the topological ...

WebPerhaps the logic is the following (Note, I infer this logic from sentences and there may be something deeper they mean. This is what I want to discuss in this post). Since the instanton action is ocassionally independent of $\tau$, when we continue back, formally substitute $\tau=it$, we still have such an exponential suppression. WebNote that in the limit , the gauge sector approaches one of the pure-gauge transformation , which is the same as the pure gauge transformation to which the BPST instanton approaches as at =, hence establishing the connection between the …
