Gravitational 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...
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 کاملMagnetoatmospheric Oscillations in Flux Tubes
The present investigation is a continuation of earlier work by Hasan & Christensen-Dalsgaard (1992) and Banerjee, Hasan & Christensen-Dalsgaard (1995), who has examined the eeects of a weak vertical magnetic eld on the normal adiabatic modes of an isothermal atmosphere by combining a semi-analytic approach, based on asymp-totic dispersion relations, with numerical solutions. In the present stud...
متن کاملCharm production in flux tubes.
We argue that the non-perturbative Schwinger mechanism may play an important role in the hadronic production of charm. We present a flux tube model which assumes that the colliding hadrons become color charged because of gluon exchange, and that a single non-elementary flux tube is built up as they recede. The strong chromoelectric field inside this tube creates quark pairs (including charmed o...
متن کاملDomain 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...
