Superdielectrics: Disorder-induced perfect screening in insulators
Ilia Komissarov, Tobias Holder, Raquel Queiroz
We study the relationship between the quantities that encode the insulating properties of matter: the ground-state quantum metric, the average localization length, and the electric…

Functional approach to superfluid stiffness: Role of quantum geometry in unconventional superconductivity
Maximilian Buthenhoff, Tobias Holder, Michael M. Scherer
Nontrivial quantum geometry of electronic bands has been argued to facilitate superconductivity even for the case of flat dispersions where the conventional contribution to the sup…
