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…

Quantum Critical Dynamics Induced by Topological Zero Modes
Ilia Komissarov, Tobias Holder, Raquel Queiroz
We investigate the low-frequency ac transport in the Su-Schrieffer-Heeger (SSH) chain with chiral disorder near the topological delocalization transition. Our key finding is that t…

Doped moiré magnets: renormalized flat bands and excitonic phases
Ilia Komissarov, Onur Erten, Pouyan Ghaemi
We explore the phase diagram of a twisted bilayer of strongly interacting electrons on a honeycomb lattice close to half-filling using the slave boson mean-field theory. Our analys…
