Holographic charge diffusion in non relativistic branes
arXiv:1412.0911 · doi:10.1016/j.physletb.2015.03.045
Abstract
In this paper, based on the principles of gauge/gravity duality and considering the so called \textit{hydrodynamic} limit we compute various charge transport properties for a class of strongly coupled non relativistic CFTs corresponding to fixed point whose dual gravitational counter part could be realized as the consistent truncation of certain non relativistic branes in the non extremal limit. From our analysis we note that unlike the case for the AdS black branes, the charge diffusion constant in the non relativistic background scales differently with the temperature. This shows a possible violation of the universal bound on the charge conductivity to susceptibility ratio in the context of non relativistic holography.
