论文摘要

以色列 - 斯图尔特理论与一阶因果关系和稳定的流体动力学之间的确切对应关系是针对零巴里昂密度零的增强不变的大型案例,以及剪切和散装扇区中使用的恒定松弛时间。为相对论的大量气体给出了依赖温度调节剂的明确表达式。应用了一阶方法中已知的稳定性和因果关系条件,并发现其中一个在这种情况下被侵犯了。

Exact correspondence between Israel-Stewart theory and first-order causal and stable hydrodynamics is established for the boost-invariant massive case with zero baryon density and the same constant relaxation times used in the shear and bulk sectors. Explicit expressions for the temperature dependent regulators are given for the case of a relativistic massive gas. The stability and causality conditions known in the first-order approach are applied and one finds that one of them is violated in this case.
