Domain Walls and Flux Tubes
We present a new vortex solution made of a domain wall compactified into a cylinder and stabilized by the magnetic flux within. When the thickness of the wall is much less than the radius of the vortex some precise results can be obtained, such as the tension spectrum and profile functions. This vortex can naturally end on the wall that has created it, making the simplest junction between a wal...
متن کاملQuantum Fusion of Strings (Flux Tubes) and Domain Walls
We consider formation of composite strings and domain walls as a result of fusion of two elementary objects (elementary strings in the first case and elementary walls in the second) located at a distance from each other. The tension of the composite object T2 is assumed to be less than twice the tension of the elementary object T1, so that bound states are possible. If in the initial state the ...
متن کاملDomain Walls and Flux Tubes in N = 2 SQCD: D-Brane Prototypes
This paper could have been entitled “D branes and strings from flesh and blood.” We study field theoretic prototypes of D branes/strings. To this end we consider (2+1)-dimensional domain walls in (3+1)-dimensional N = 2 SQCD with SU(2) gauge group and Nf = 2 flavors of fundamental hypermultiplets (quarks). This theory is perturbed by a small mass term of the adjoint matter which, in the leading...
متن کاملFlow instabilities of magnetic flux tubes III. Toroidal flux tubes
Context. The stability properties of toroidal magnetic flux tubes are relevant for the storage and emergence of magnetic fields in the convective envelope of cool stars. In addition to buoyancyand magnetic tension-driven instabilities, flux tubes are also susceptible to an instability induced by the hydrodynamic drag force. Aims. Following our investigation of the basic instability mechanism in...
متن کاملGravitational Flux Tubes
By studying multidimensional Kaluza-Klein theories, or gravity plus U(1) or SU(2) gauge fields it is shown that these theories possess similar flux tube solutions. The gauge field which fills the tube geometry of these solutions leads to a comparision with the flux tube structures in QCD. These solutions also carry a “magnetic” charge, Q, which for the SU(2) Einstein-Yang-Mills (EYM) system exh...
