三角形反常的流体动力学

Hydrodynamics with Triangle Anomalies

Dam T. Son, Piotr Surowka

摘要:

我们考虑流体动力学制度的理论与量子异常的全球电流。我们表明,迄今为止被丢弃的项中的守恒电流不仅是允许的对称性,但实际上是所需的三角形异常和热力学第二定律。这一项导致了许多新的效应,其中之一是在非零化学势的旋转流体中的手性分离。新的动力学系数可以通过反常系数和状态方程以独特的方式表达。我们简要地讨论了物理情况下,包括重离子碰撞,这个新的流体动力学项的相关性。

英文摘要:

We consider the hydrodynamic regime of theories with quantum anomalies for global currents. We show that a hitherto discarded term in the conserve current is not only allowed by symmetries, but is in fact required by triangle anomalies and the second law of thermodynamics. This term leads to a number of new effects, one of which is chiral separation in a rotating fluid at nonzero chemical potential. The new kinetic coefficients can be expressed, in a unique fashion, through the anomalies coefficients and the equation of state. We briefly discuss the relevance of this new hydrodynamic term for physical situations, including heavy ion collisions.
