Plasmons in Holographic Graphene
For strongly correlated systems, holography is an ideal framework for computing plasmon properties. We identify all these self-sourced collective modes in holographic Maxwell theories via a specific choice of boundary condition. This method's potential to improve holographic models of e.g. graphene is demonstrated by computing the 2D-plasmon dispersion, which naturally connects to regions in parameter space accessible to conventional methods. Beyond that, this method also allows to compute the dynamical charge response of strange metals, which could be compared to experiments using (M-EELS).
