远离平衡态的相对论流体的非线性约束

Nonlinear Constraints on Relativistic Fluids Far From Equilibrium

Fabio S. Bemfica, Marcelo M. Disconzi, Vu Hoang, Jorge Noronha, Maria Radosz

摘要:

新的限制,必须持有以色列-斯图尔特一样的流体动力学理论是因果关系远离平衡。这些理论中的因果关系,局部存在性和唯一性的解决方案是足够的条件。我们的研究结果保持在完整的非线性制度,考虑到体积和剪切粘度(在零化学势),没有任何简化的对称性或近平衡的假设。我们的研究结果提供了根本的限制,在流体动力学远离平衡的粘性修正的大小。

英文摘要:

New constraints are found that must necessarily hold for Israel-Stewart-like theories of fluid dynamics to be causal far away from equilibrium. Conditions that are sufficient to ensure causality, local existence, and uniqueness of solutions in these theories are also presented. Our results hold in the full nonlinear regime, taking into account bulk and shear viscosities (at zero chemical potential), without any simplifying symmetry or near-equilibrium assumptions. Our findings provide fundamental constraints on the magnitude of viscous corrections in fluid dynamics far from equilibrium.
