Towards 't Hooft parameter corrections to charge transport in strongly-coupled plasma

Understand

We study R-charge transport in a wide class of strongly-coupled supersymmetric plasmas at finite temperature with 't Hooft coupling corrections.

• To achieve this, we use the gauge/string duality and include the full set of order(\alpha'^3) corrections to the supergravity backgrounds given at zeroth order by the direct product of the AdS-Schwarzschild black hole with a five-dimensional compact Einstein manifold.
• On general grounds, the reduction leads to a large number of higher derivative operators, which we reduce using the symmetries of the solution.
• We are left with a universal set of operators whose coefficients can in principle be fixed by carrying out an explicit compactification.
