Experimental identification of quantum spin liquids remains a challenge, asthe pristine nature is to be seen in asymptotically low temperatures. We heretheoretically show that the precursor of quantum spin liquids appears in thespin dynamics in the paramagnetic state over a wide temperature range. Usingthe cluster dynamical mean-field theory and the continuous-time quantum MonteCarlo method, which are newly developed in the Majorana fermion representation,we calculate the dynamical spin structure factor, relaxation rate in nuclearmagnetic resonance, and magnetic susceptibility for the honeycomb Kitaev modelwhose ground state is a canonical example of the quantum spin liquid. We findthat dynamical spin correlations show peculiar temperature and frequencydependence even below the temperature where static correlations saturate. Theresults provide the experimentally-accessible symptoms of the fluctuatingfractionalized spins evincing the quantum spin liquids.
