Density response of holographic metallic IR fixed points with translational pseudo-spontaneous symmetry breaking
Abstract The density response of charged liquids contains a collective excitation known as the plasmon. In holographic systems with translational invariance the origin of this collective excitation is traced back to the presence of zero-sound. Using a holographic model in which translational symmetr...
