2n维带电流体的高阶导数修正

Higher Derivative Corrections to Charged Fluids in 2n Dimensions

Nabamita Banerjee, Suvankar Dutta, Akash Jain

摘要:

本文研究了$2n$ -维($n\geq 2$)中直到次导导数阶的反常带电流体。只有规范异常的影响是重要的,在这个顺序。利用欧几里德配分函数形式,我们找到了不同的子领先阶输运系数出现在奇偶偶和奇部门的流体的约束。我们引入了一种新的机制来计算任意阶导数的不同流体数据。我们表明,只有独立的标量数据的知识是足够的,找到的约束。在附录中,我们进一步扩展这种分析,以获得流体数据在次-次领先的顺序(其中规范和重力异常的贡献)的宇称奇流体。

英文摘要:

We study anomalous charged fluid in $2n$-dimensions ($n\geq 2$) up to sub-leading derivative order. Only the effect of gauge anomaly is important at this order. Using the Euclidean partition function formalism, we find the constraints on different sub-leading order transport coefficients appearing in parity-even and odd sectors of the fluid. We introduce a new mechanism to count different fluid data at arbitrary derivative order. We show that only the knowledge of independent scalar-data is sufficient to find the constraints. In appendix we further extend this analysis to obtain fluid data at sub-sub-leading order (where both gauge and gravitational anomaly contribute) for parity-odd fluid.
