Instanton constituents in the O(3) model at finite temperature

arXiv:0707.0775 · doi:10.1103/PhysRevLett.100.051602

Abstract

It is shown that instantons in the O(3) model at finite temperature consist of fractional charge constituents and the (topological) properties of the latter are discussed.
