Spontaneous chiral-symmetry breaking in three-dimensional QED.
A detailed analysis is given of chiral-symmetry breaking in the large-flavor (N) limit of quantum electrodynamics in (2+1) dimensions. Analytical and numerical solutions of the homogeneousExpand

Chiral hierarchies and flavor-changing neutral currents in hypercolor.
Dynamical chiral-symmetry breaking in asymptotically free theories with a slowly running coupling is analyzed. When the confinement scale ..lambda.. is much less than the cutoff M beyond which theExpand

Spontaneous breaking of parity in (2+1)-dimensional QED.
The spontaneous generation of parity- (P) and time-reversal- (T) violating masses in (2+1)-dimensional QED is studied in the large-N limit, where N is the number of two-component complex fermions.Expand

Fractional angular momentum in the O(3) nonlinear sigma model coupled to an Abelian gauge field with a topological mass is studied semiclassically. The results are suggestive of a phase transition inExpand
