Skyrmions 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 کاملSkyrmions 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 کاملAnomalies and Fermion Zero Modes on Strings and Domain Walls
We show that the mathematical relation between non-abelian anomalies in 2n dimensions, the parity anomaly in 2n + 1 dimensions, and the Dirac index density in 2n + 2 dimensions can be unders tood in terms of the physics of fermion zero modes on strings and domain walls. We show that the Dirac equation possesses chiral zero modes in the presence of strings in 2n +2 dimensions (such as occur in a...
متن کاملDynamics of Strings between Domain Walls
Configurations of vortex-strings stretched between or ending on domain walls were previously found to be 1/4 BPS states. Among zero modes of string positions, the center of mass of strings in each region between two adjacent domain walls is shown to be non-normalizable whereas the rests are normalizable. We study dynamics of vortex-strings stretched between separated domain walls by using two m...
متن کاملSpontaneous and Induced Decay of Metastable Strings and Domain Walls
We consider decay of metastable topological configurations such as strings and domain walls. The transition from a state with higher energy density to a state with lower one proceeds through quantum tunneling or through thermally catalyzed quantum tunneling (at sufficiently small temperatures). The transition rate is calculated at zero temperature including the preexponential factor and also at...
