Inlo-pub-02/02 Monopoles from Instantons

نویسنده

  • FALK BRUCKMANN
چکیده

The relation between defects of Abelian gauges and instantons is discussed for explicit examples in the Laplacian Abelian gauge. The defect coming from an instanton is pointlike and becomes a monopole loop with twist upon perturbation. The interplay between magnetic charge, twist and instanton number – encoded as a Hopf invariant – is investigated with the help of a new method, an auxiliary Abelian fibre bundle.

We study spherically and axially symmetric monopoles of the SU(2) EinsteinYang-Mills-Higgs-dilaton (EYMHD) system with a new coupling between the dilaton field and the covariant derivative of the Higgs field. This coupling arises in the study of (4+ 1)dimensional vortices in the Einstein-Yang-Mills (EYM) system. [email protected] [email protected]

We consider Ward’s generalized self-duality equations for U(2r) Yang-Mills theory on R and their Moyal deformation under self-dual noncommutativity. Employing an extended ADHM construction we find two kinds of explicit solutions, which generalize the ’t Hooft and BPST instantons from R to noncommutative R. The BPST-type configurations appear to be new even in the commutative case.

Instantons and Monopoles in Maximal Abelian Projection of SU (2) Gluodynamics

We show that the instantons induce the abelian monopoles in the Maximal Abelian Projection of SU(2) gluodynamics. As an example we consider the case of one instanton and the case of a set of instantons arranged along a straight line. The abelian monopoles which are induced by instantons may play some role in the confinement scenario. ∗E–mail address: [email protected]
