Abstract:
In this talk, we generalize Witten's non-abelian bosonization in (1+1)-D to two and three spatial dimensions. Our theory applies to fermions with relativistic dispersion. The bosonized theories are non-linear sigma models with level-1 Wess-Zumino-Witten terms. We apply the bosonization results to the SU(2) gauge-matter theory of the Mott insulators in 1,2,3 spatial dimensions, and twisted bilayer graphene.
