In addition, we will see how it has influenced various aspects of daily life, and what the future prospects are. Without a doubt, Meron (physics) is a fascinating topic worth exploring in depth.

Half-instanton solution of Yang–Mills theory

A meron or half-instanton is a Euclidean space-time solution of the Yang–Mills field equations. It is a singular non-self-dual solution of topological charge 1/2. The instanton is believed to be composed of two merons.^[1]

A meron can be viewed as a tunneling event between two Gribov vacua.^[2] In that picture, the meron is an event which starts from vacuum, then a Wu–Yang monopole emerges, which then disappears again to leave the vacuum in another Gribov copy.
