Thermoelectric behavior of hot collisional and magnetized QCD medium from an effective kinetic theory

Abstract

In this paper, we study the thermoelectric behavior of the quark-gluon plasma within the framework of an effective kinetic theory. We adopt a quasiparticle model to incorporate the effects of a thermal medium. The thermoelectric response of the medium is quantified in terms of the Seebeck and Nernst coefficient. Utilizing the relaxation time approximation and Bhatnagar-Gross-Krook collision kernels in an effective Boltzmann equation, we compute the dependence of the Seebeck coefficients on collision temperature and quark chemical potential. We furthermore explore the magnetic field dependence of the thermoelectric effects in a weakly and strongly magnetized medium. The thermoelectric response of a hot QCD medium is shown to be most prominent at low temperatures close to the transition temperature.
