Query: Second-order transport, quasinormal modes and zero-viscosity limit in
  the Gauss-Bonnet holographic fluid   Gauss-Bonnet holographic fluid is a useful theoretical laboratory to study
the effects of curvature-squared terms in the dual gravity action on transport
coefficients, quasinormal spectra and the analytic structure of thermal
correlators at strong coupling. To understand the behavior and possible
pathologies of the Gauss-Bonnet fluid in $3+1$ dimensions, we compute
(analytically and non-perturbatively in the Gauss-Bonnet coupling) its
second-order transport coefficients, the retarded two- and three-point
correlation functions of the energy-momentum tensor in the hydrodynamic regime
as well as the relevant quasinormal spectrum. The Haack-Yarom universal
relation among the second-order transport coefficients is violated at second
order in the Gauss-Bonnet coupling. In the zero-viscosity limit, the
holographic fluid still produces entropy, while the momentum diffusion and the
sound attenuation are suppressed at all orders in the hydrodynamic expansion.
By adding higher-derivative electromagnetic field terms to the action, we also
compute corrections to charge diffusion and identify the non-perturbative
parameter regime in which the charge diffusion constant vanishes.
