Skyrmions and domain walls in ( 2 + 1 ) dimensions
We study classical solutions of the vector O(3) sigma model in (2 + 1) dimensions, spontaneously broken to O(2) × Z2. The model possesses Skyrmion-type solutions as well as stable domain walls which connect different vacua. We show that different types of waves can propagate on the wall, including waves carrying a topological charge. The domain wall can also absorb Skyrmions and, under appropri...
متن کاملSkyrmions from instantons inside domain walls.
Some years ago, Atiyah and Manton described a method to construct approximate Skyrmion solutions from Yang-Mills instantons. Here we present a dynamical realization of this construction using domain walls in a five-dimensional gauge theory. The non-Abelian gauge symmetry is broken in each vacuum but restored in the core of the domain wall, allowing instantons to nestle inside the wall. We show ...
متن کاملDomain Walls and Solitons in Odd Dimensions
We discuss a consistency condition for the existence of smooth soliton solutions which interpolate between vacua in odd-dimensional theories. In particular we apply this analysis to a wide class of supergravities to rule out the existence of smooth domain walls interpolating between supersymmetric vacua. Normale Supérieure.
متن کاملDomain walls from ten dimensions
We write down the general conditions for N = 1 supersymmetric four– dimensional domain walls, deriving them from a ten–dimensional point of view using generalized complex geometry. In cases where the compactification allows for a truncation to a finite number of fields, we make contact with a four–dimensional effective description. In the context of the AdS/CFT correspondence, the equations can...
متن کاملStatic skyrmions in (2+1) dimensions
In the spirit of previous papers, but using more general field configurations, the non-linear O(3) model in (2+1)-D, modified by the addition of both a potential-like term and a Skyrme-like term, is considered. The instanton solutions are numerically evolved in time and some of their stability properties studied. They are found to be stable, and a repulsive force is seen to exist among them. Th...
