Vacuum Periodicity in a Yang-Mills Quantum Theory

We propose a description of the vacuum in Yang-Mills theory and arrive at a physical interpretation of the pseudoparticle solution and the attendant violation of symmetries. The...

Fractional charge and zero modes for planar systems in a magnetic field

Attention is drawn to a relation between the recently discovered three-dimensional chiral anomaly and fermion zero modes. Application to planar systems of electrons in an extern...

Solitons with fermion number ½

We study the structure of soliton-monopole systems when Fermi fields are present. We show that the existence of a nondegenerate, isolated, zero-energy, $c$-number solution of th...

Zero modes of the vortex-fermion system
