Thermo-electric transport in non-extensive QCD matter in presence of magnetic field

Abstract

We investigate the thermo-electric response of a magnetized non-extensive quark-gluon plasma within the framework of kinetic theory using the relaxation time approximation (RTA). The interactions among the partons are incorporated through a quasi-particle model, where the medium-dependent quark mass is obtained from the poles of the resummed hard-thermal-loop (HTL) propagator. Our results show that non-extensive effects suppress the Seebeck coefficient both in the absence and in the presence of an external magnetic field. In contrast, the Nernst coefficient, which arises only in the presence of a magnetic field, is found to be significantly enhanced by non-extensivity. These findings demonstrate that deviations from equilibrium can substantially modify the thermo-electric transport properties of the quark gluon plasma.
