Abstract
We investigate the thermoelectric effect for baryon rich plasma produced in heavy ion collision experiments. We estimate the associated Seebeck coefficient for the hadronic matter. Using kinetic theory within relaxation time approximation we calculate the Seebeck coefficient of a hadronic medium with a temperature gradient. The calculation is performed for hadronic matter modeled by hadron resonance gas model with hadrons and resonance states up to a cutoff in the mass as 2.25 GeV. We argue that the thermoelectric current produced by such effect can produce magnetic field in heavy ion collision experiments.
Highlights
Transport coefficients of strongly interacting matter under extreme conditions of temperature, density, and/or magnetic fields have been one of the most challenging interests in the field of strong interaction physics
In the context of relativistic heavy ion collision experiments (RHIC), these are important input parameters that enter in the dissipative relativistic hydrodynamics as well as transport simulations, that are being used to describe the evolution of the matter subsequent to a heavy ion collision
We have attempted to study the thermoelectric effect of a thermalized hadronic medium with a temperature gradient
Summary
Transport coefficients of strongly interacting matter under extreme conditions of temperature, density, and/or magnetic fields have been one of the most challenging interests in the field of strong interaction physics. The crucial parameter that enters in the time dependence of the magnetic field in the medium is the electrical conductivity, σel [12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30] These transport coefficients for quark matter can be estimated using different approaches like perturbative QCD, and different effective models (see [31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56]). We estimate the Seebeck coefficient of the multicomponent hadronic system within the HRG model
