相对论性核物质的物态方程和输运系数

Equation of State and Transport Coefficients of Relativistic Nuclear Matter

Azwinndini Muronga

摘要:

为了定性地评价热而致密的核物质的时空演化,必须知道基本的状态方程和输运系数。在这项研究中,一个特定的状态方程进行了研究:π介子气体。经典的或标准的传输系数,即体积粘度,剪切粘度和热导率除以相应的耗散通量的弛豫时间,然后作为质量温度比的函数进行研究。

英文摘要:

In order to evaluate qualitatively the space-time evolution of hot and dense nuclear matter the underlying equation of state and transport coefficients must be known. In this study a specific equation of state is studied: the pion gas. The classical or standard transport coefficients, namely the bulk viscosity, shear viscsoity and thermal conductivity are devided by the relaxation times for the corresponding dissipative fluxes and then studied as functions of mass to temperature ratio.
