The dual Meissner effect in SU(2) Landau gauge
Tsuneo Suzuki, Katsuya Ishiguro, Yoshihiro Mori, Toru Sekido
Abstract
The dual Meissner effect is observed without monopoles in quenched SU(2) QCD with Landau gauge-fixing. Abelian as well as non-Abelian electric fields are squeezed. Magnetic displacement currents which are time-dependent Abelian magnetic fields play a role of solenoidal currents squeezing Abelian electric fields. Monopoles are not always necessary to the dual Meissner effect. The squeezing of the electric flux means the dual London equation and the massiveness of the Abelian electric fields as an asymptotic field. The mass generation of the Abelian electric fields is related to a gluon condensate <AaμAaμ>≠ 0 of mass dimension 2.
