Dynamics of fractionalization in quantum spin liquids

I will present the theory of dynamical spin response for the Kitaev honeycomb model, discussing exact results for the structure factor — which shows signatures of spin fractionalization into emergent quasiparticles: Majorana fermions and fluxes of Z2 gauge field — in gapped and gapless, Abelian and non-Abelian quantum spin-liquid (QSL) phases.
