Weyl corrections to holographic conductivity
Adam Ritz, John Ward
For conformal field theories which admit a dual gravitational description in anti-de Sitter space, electrical transport properties, such as conductivity and charge diffusion, are d…
Dyon dynamics near marginal stability and non-BPS states
Adam Ritz, Arkady Vainshtein
We derive the general form of the moduli-space effective action for the long-range interaction of two BPS dyons in N=2 gauge theories. This action determines the bound state struct…
Universal conductivity and central charges
Pavel Kovtun, Adam Ritz
We discuss a class of critical models in d>1+1 dimensions whose electrical conductivity and charge susceptibility are fixed by the central charge in a universal manner. We comment…
Black holes and universality classes of critical points
Pavel Kovtun, Adam Ritz
We argue that there exists an infinite class of conformal field theories in diverse dimensions, having a universal ratio of the central charge c to the normalized entropy density c…
