Quantum Nonabelian Monopoles
There are several reasons to be interested in quantum, nonabelian monopoles. First, if confinement of QCD is a sort of dual superconductor, it is likely to be one of nonabelian variety. Then the effective degrees of freedom involve nonabelian, and not, better understood abelian monopoles. Second, the phenomenon of confinement has to do with fully quantum mechanical, and not semi-classical, beha...
متن کاملNonabelian Monopoles and Confinement: New Prospects
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...
متن کاملOn the Stability of Gravitating Nonabelian Monopoles
The behaviour of magnetic monopole solutions of the Einstein-YangMills-Higgs equations subject to linear spherically symmetric perturbations is studied. Using Jacobi’s criterion some of the monopoles are shown to be unstable. Furthermore the numerical results and analytical considerations indicate the existence of a set of stable solutions. ∗e-mail: [email protected]
متن کاملNonabelian Monopoles and the Vortices that Confine Them
Nonabelian magnetic monopoles of Goddard-Nuyts-Olive-Weinberg type have recently been shown to appear as the dominant infrared degrees of freedom in a class of softly broken N = 2 supersymmetric gauge theories in which the gauge group G is broken to various nonabelian subgroups H by an adjoint Higgs VEV. When the low-energy gauge group H is further broken completely by e.g. squark VEVs, the mon...
متن کاملMassless and Massive Monopoles Carrying Nonabelian Magnetic Charges
The properties of BPS monopoles carrying nonabelian magnetic charges are investigated by following the behavior of the moduli space of solutions as the Higgs field is varied from a value giving a purely abelian symmetry breaking to one that leaves a nonabelian subgroup of the gauge symmetry unbroken. As the limit of nonabelian unbroken symmetry is reached, some of the fundamental abelian monopo...
