Following an idea of Gaiotto, a symplectic representation of a complex Lie group G defines a complex Lagrangian subvariety inside the moduli space of G-Higgs bundles. The talk will discuss the case of G=SL(2) and its link with determinant divisors, or equivalently Brill-Noether loci, in the moduli space of semistable SL(2)-bundles.
