Abstract

We calculate the shear \ensuremathη(T) and bulk viscosities \ensuremathζ(T) as well as the electric conductivity \ensuremathσ_e(T) and heat conductivity \ensuremathκ(T) within the Nambu--Jona-Lasinio model for three flavors as a function of temperature as well as the entropy density s(T), pressure P(T), and speed of sound c_s²(T). We compare the results with other models such as the Polyakov--Nambu--Jona-Lasinio (PNJL) model and the dynamical quasiparticle model (DQPM) and confront these results with lattice QCD data whenever available. We find the NJL model to have a limited predictive power for the thermodynamic variables and various transport coefficients above the critical temperature, whereas the PNJL model and DQPM show acceptable results for the quantities of interest.
