Non-self-dual and self-dual SU(2) calorons
Non-self-dual and self-dual SU(2) calorons
New static regular axially symmetric solutions of SU(2) Euclidean Yang-Mills theory are constructed numerically. They represent calorons having trivial Polyakov loop at spatial infinity. The solutions are labeled by two integers m, n. It is shown that besides the known, charge one self-dual periodic instanton solution, there are other non-self …
