Abstract
I have presented a study of exact dynamical correlation functions in different phases of a model QSL with the objective to look for discernible signatures of the emergent fractionalized quasiparticles in response functions directly accessible in standard experiments. The main result is the identification of salient features—qualitative and quantitative—of the Majorana fermions and gauge fluxes emerging in the Kitaev honeycomb lattice model. For the first time, my thesis provides such exact calculations of dynamical correlation functions of a 2D QSL. The resulting characteristic signatures of fractionalization, which is a hallmark of a topologically ordered phase, are visible as fingerprints betraying the presence of a QSL in future INS, ESR, and Raman scattering experiments.
