Abstract

A family of deformed AdS(4)-Reissner-Nordstrom black branes, governed by a free parameter, is derived using the ADM formalism, in the context of the membrane paradigm. Their newevent horizons, the Hawking temperature and other aspects are scrutinized. AdS/ CFT nearhorizon methods are then implemented to compute the shear viscosity-to-entropy ratio for the deformed AdS(4)-Reissner-Nordstrom metric. The Killing equation is shown to yield new values for the free parameter and the shear viscosity-toentropy ratio is used to derive a reliable range for the tidal charge. (AU)
