Excitonic contributions to dark matter-electron scattering
Nora Taufertshöfer, Vanessa Zema, Riccardo Catena +2
We determine whether excitonic effects affect predictions of dark matter (DM)-electron scattering rates by calculating the energy- and momentum-dependent energy-loss function, incl…

Electronic structure of liquid xenon in the context of light dark matter direct detection
Riccardo Catena, Luca Marin, Marek Matas +2
We present a description of the electronic structure of xenon within the density-functional theory formalism with the goal of accurately modeling dark-matter-induced ionisation in…

A general upper bound on the light dark matter scattering rate in materials
Riccardo Catena, Michał Iglicki
Combining an effective theory description of spin-1/2 dark matter (DM)-electron interactions in materials with linear response theory provides a powerful framework to model the sca…
