Scientific paper

In an SU(5) GUT model of phase transitions in the early universe, we show how the degeneracy between vacua with different spontaneously broken CP can be dynamically lifted by creating a bias through the formation of a heavy fermion pair condensate of fermions. The fermion condensate bias drives a transition to a unique vacuum state. The final resulting transition to a true vacuum eliminates the domain walls, solving the domain wall problem in a matter-antimatter domain cosmology.
