Conductivity at finite 't Hooft coupling from AdS/CFT

We use the AdS/CFT correspondence to study the DC conductivity of massive N=2N=2 hypermultiplet fields in an N=4SU(Nc)N=4SU(Nc) super Yang–Mills theory plasma in the large NcNc and finite 't Hooft coupling. We also discuss general curvature-squared and Gauss–Bonnet corrections on the DC conductivity.
