标题： Causal and Stable Relativistic Hydrodynamic Fluctuations

摘要： 当两个核以接近光速的速度碰撞时，会形成一种称为夸克-胶子等离子体的流体状态。 对这种流体动力学的理解引发了对耗散相对论流体动力学的大量研究。 涨落-耗散定理表明，任何耗散的动力系统也会经历热涨落；然而，这种涨落通常不包含在夸克-胶子等离子体的建模中。 这项工作讨论了一种新的方法，用于确定流体力学框架是否与热涨落一致。 我们开发了一种新的方法来计算相对论流体动力学系统的噪声关联器，并将其应用于一般流体力学框架中的伊萨拉-斯图亚特理论。 显示英文摘要

摘要： When two nuclei collide close to the speed of light, a fluid state known as the quark-gluon plasma is formed. Attempts to understand the dynamics of this fluid have generated significant research into dissipative relativistic fluid dynamics. The fluctuation-dissipation theorem implies that any dissipative dynamical system will also experience thermal fluctuations; however, such fluctuations are not typically included in the modeling of the quark-gluon plasma. This work discusses a new method of determining whether a hydrodynamic framework is consistent with thermal fluctuations. We develop a new method for calculating the noise correlator of relativistic hydrodynamic systems and apply it to Israel-Stewart theory in a general hydrodynamic frame.
