Impact of (magneto-)thermoelectric effect on diffusion of conserved charges in hot and dense hadronic matter
arxiv(2024)
摘要
We investigate the thermoelectric effect, which describes the generation of
an electric field induced by temperature and conserved charge chemical
potential gradients, in the hot and dense hadronic matter created in heavy-ion
collisions. Utilizing the Boltzmann kinetic theory within the repulsive
mean-field hadron resonance gas model, we evaluate both the diffusion
thermopower matrix and diffusion coefficient matrix for the baryon number
(B), electric charge (Q), and strangeness (S).The Landau-Lifshitz frame
is enforced in the derivation. We find that the thermoelectric effect hinders
the diffusion processes of multiple conserved charges, particularly reducing
the coupling between electric charge and baryon number (strangeness) in baryon
(strangeness) diffusion. Based on the fact that the repulsive mean-field
interactions between hadrons have a significant effect on the diffusion
thermopower matrix and diffusion coefficient matrix in the baryon-rich region,
we extend the investigation to include the impact of the magnetic field,
analyzing the magneto-thermoelectric effect on both the diffusion coefficient
matrix and the Hall-like diffusion coefficient matrix. The sensitivity of the
magnetic field-dependent diffusion thermopower matrix and
magneto-thermoelectric modified diffusion coefficient matrix to the choices of
various transverse conditions is also studied.
