Monopolonium in confining phase
  This paper has been withdrawn by the author(s), due the following reasons. A similar system for a different purpose has already been studied in Phys.Rev.D60:083001,1999 (astro-ph/9904315). Moreover, our analysis was wrong because we have missed the large frictional forces that will rapidly damp out the energy in the oscillating monopolonium system.
