论文摘要
导电介质中的热梯度和/或化学势梯度可以导致电场，这种效果称为热电效应或塞贝克效应。在重离子碰撞的背景下，我们估计了Nambu-Jona Lasinio（NJL）模型中夸克物质的热电传输系数。我们估计热和密集夸克物质的热导率，电导率和塞贝克系数。这些系数是在松弛时间近似中使用相对论玻尔兹曼传输方程计算的。夸克的放松时间是从NJL模型中的Quark-Quark和Quark-Antiquark散射中估计的。
A thermal gradient and/or a chemical potential gradient in a conducting medium can lead to an electric field, an effect known as thermoelectric effect or Seebeck effect. In the context of heavy-ion collisions, we estimate the thermoelectric transport coefficients for quark matter within the ambit of the Nambu-Jona Lasinio (NJL) model. We estimate the thermal conductivity, electrical conductivity, and the Seebeck coefficient of hot and dense quark matter. These coefficients are calculated using the relativistic Boltzmann transport equation within relaxation time approximation. The relaxation times for the quarks are estimated from the quark-quark and quark-antiquark scattering through in-medium meson exchange within the NJL model.
