  • Stern, Allen (American Physical Society, 1989-04-17)
    We perform the canonical quantization for a system of non-Abelian chiral bosons. We show that unlike in the Wess-Zumino-Witten model, the left- and right-handed current densities do not simultaneously span Kac-Moody algebras ...
  • Stern, Allen (American Physical Society, 2000-08-14)
    We show how to map the Belavin-Polyakov instantons of the O(3)-nonlinear σ model to a dual theory where they then appear as nontopological solitons. They are stationary points of the Euclidean action in the dual theory, ...
