Transport Properties with Gauss-Bonnet corrections using soft-wall model of holographic QCD

We study the renormalization group (RG) flow of transport coefficients of a 3+1 dimensional strongly coupled system using holography. Introducing Gauss-Bonnet corrections in the gravity system we study the behavior of ac conductivity and diffusion constant using the soft-wall model of the bottom-up approach. Further we show the dependence of transport coefficients on the chemical potential of the system. Keywords: Holographic QCD, Soft-wall model, Gauss-Bonnet corrections
