Description

We give an overview over new applications of gauge/gravity, in particular to systems in which a rho meson condensate forms. This can happen both at finite isospin density or in an external magnetic field. We discuss the hydrodynamic properties of these spatially anisotropic systems, in which the shear viscosity becomes a tensor. The non-helicity-two components of this tensor are non-universal and temperature dependent at leading order in N and lambda, while preserving the 1/4 pi bound. -- For the external B field, the rho meson condensate is spatially modulated, forming a triangular lattice. This is similar to recent results found using effective field theory and lattice calculations.
