Abstract
The magnetic monopole
condensate is calculated in the dual Monopole Nambu-Jona-Lasinio model
with dual Dirac strings suggested in [1,2] as a functional of the
dual Dirac string shape. The calculation is carried out in the tree
approximation in the scalar monopole-antimonopole collective excitation
field. The integration over quantum fluctuations of the dual-vector
monopole-antimonopole collective excitation field around the Abrikosov
flux line and string shape fluctuations are performed explicitly. We
claim that there are important contributions of quantum and string shape
fluctuations to the magnetic monopole condensate.
