摘要:We discuss quantum mechanical aspects of non abelian monopoles in relation to the phenomena
of confinement and dynamical symmetry breaking. In supersymmetric theories there are three
types of confining vacua have been found: (i) abelian dual superconductor; (ii) weakly-coupled
nonabelian dual superconductor; and (iii) strongly-coupled, nonabelian Argyres-Douglas vacua.
The last class of systems occur very generally in supersymmetric theories; they are characterized
by strongly-coupled nonabelian monopoles and dyons: confinement and dynamical symmetry
breaking are caused by the condensation of monopole composites, rather than by condensation of
single weakly-coupled monopoles. There are strong constraints on which kind of monopoles can
appear as the infrared degrees of freedom, related to the proper realization of the global symmetry
of the theory. Drawing analogies to some of the phenomena found here, we make a speculation
on the ground state of the standard QCD.
