Abstract
We obtain holographic realizations for systems that have strong similarities to Mott insulators and supersolids after examining the ground states of EinsteinMaxwellscalar systems The real part of the AC conductivity has a hard gap and a discrete spectrum only We add momentum dissipation to resolve the δfunction in the conductivity due to translational invariance We develop tools to directly calculate the Drude weight for a large class of solutions and to support our claims Numerical RG flows are also constructed to verify that such saddle points are IR fixed points of asymptotically AdS4 geometriesThis 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
