Abstract
A model consisting of d+1dimensional gravity coupled to spacetime filling charged branes is used to study the effects of backreaction The charged black holes arising from this simple model reflect the nonlinearity of the gauge field and are thermodynamically stable By analysing fluctuations of the system we corroborate that at low values of the temperature or large chemical potential backreaction effects from the branes are dominant We also provide a generalisation of the Iqbal and Liu strategy to calculate the DC conductivity in which a mass term for the gauge field fluctuation is included This mass term gives the value of the residue of the pole at zero frequency in the imaginary part of the AC conductivity as well as the running of the DC conductivity with the bulk radiusThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
