Since holography yields exact results, even in situations where perturbation theory is not applicable, it an ideal framework for modeling strongly correlated systems. We extend previous holographic methods to take the dynamical charge response into account and use this perform first computation of dispersion relation plasmons. As strange metals can be measured using new technique momentum-resolved electron energy-loss spectroscopy (M-EELS), plasmon properties are next milestone verifying predictions from models states matter.
