NAMBU-JONA-LASINIO VERSION OF MAGNETIC MONOPOLE PHYSICS WITH DUAL DIRAC STRINGS

We propose a model where a condensate of monopole-antimonopole pairs l eads to confinement. Magnetic monopoles are considered as massless fer mion fields interacting via local four-monopole interaction of the Nam bu-Jona-Lasinio kind leading to monopole condensation. Condensation of magnetic monopole currents and any derivative of them are obtained. I t is shown that the bosonized version of this Monopole Nambu-Jona-Lasi nio (MNJL) model is reducing to London's theory of dual superconductiv ity within Dirac's extension of Maxwell's Electrodynamics. The affinit y of the MNJL-model with Compact Quantum Electrodynamics is discussed.
