Charge density response and fake plasmons in holographic models with strong translation symmetry breaking
Abstract We study the charge density response in holographic models with explicit trans- lation symmetry breaking which is relevant in IR. In particular, we focus on Q-lattices and the Bianchy VII helix. We show that the hydrodynamic sound mode is removed from the spectrum due to the strong momentum...
