Flux tube solutions in Kaluza-Klein theory

Spherically symmetric, vacuum solutions in five- and seven-dimensional Kalu za-Klein theory are obtained. These solutions are Bur tubes with constant c ross sectional size, located between (+) and (-) Kaluzn-Klein 'electrical' and 'magnetic' charges disposed, respectively, at r = +/-infinity and fille d with constant Kaluza-Klein 'electrical' and 'magnetic' fields. These obje cts are surprisingly similar to the flux tubes which form between two monop oles in type II superconductors and also the hypothesized colour field flux tube that is thought to form between two quarks in the QCD vacuum.
