Makoto Natsuume, Takashi Okamura
TL;DR
This paper calculates new transport coefficients for causal hydrodynamics in M2 and M5-branes using a Kubo-like formula, confirming relaxation times with previous sound mode results.
Contribution
It introduces new transport coefficients for M-theory branes using a specific Kubo-like approach, advancing the understanding of hydrodynamics in these systems.
Findings
Transport coefficients for M2 and M5-branes derived.
Relaxation times match previous sound mode calculations.
Supports the validity of the Kubo-like formula in this context.
Abstract
We obtain new transport coefficients of causal hydrodynamics for the M2 and the M5-brane using a Kubo-like formula proposed by Baier, Romatschke, Son, Starinets, and Stephanov (arXiv:0712.2451 [hep-th]). The relaxation times agree with the ones obtained from the "sound mode" in our paper (arXiv:0712.2916 [hep-th]).
