Fermions in random gauge fields and chiral-symmetry breaking

Random superpositions of gauge fields such that a fermion can propagate in them along the same one-dimensional trajectory in four-dimensional space over arbitrary distances without reduction of the amplitude are considered. Conditions are found under which such structures possess a finite density of...

Zusammenfassung:Random superpositions of gauge fields such that a fermion can propagate in them along the same one-dimensional trajectory in four-dimensional space over arbitrary distances without reduction of the amplitude are considered. Conditions are found under which such structures possess a finite density of fermion zero modes. The possibility of chiral-symmetry breaking in these configurations of gauge fields is explored.
