Many-Body Superconductivity in Topological Flat Bands
Jonah Herzog-Arbeitman, Aaron Chew, Kukka-Emilia Huhtinen +2
In a flat band superconductor, bosonic excitations can disperse while unpaired electrons are immobile. To study this strongly interacting system, we construct a family of multi-ban…
Magnetic Bloch Theorem and Reentrant Flat Bands in Twisted Bilayer Graphene at Flux
Jonah Herzog-Arbeitman, Aaron Chew, B. Andrei Bernevig
Bloch's theorem is the centerpiece of topological band theory, which itself has defined an era of quantum materials research. However, Bloch's theorem is broken by a perpendicular…
Revisiting flat band superconductivity: dependence on minimal quantum metric and band touchings
Kukka-Emilia Huhtinen, Jonah Herzog-Arbeitman, Aaron Chew +2
A critical result in superconductivity is that flat bands, though dispersionless, can still host nonzero superfluid weight due to quantum geometry. We show that the derivation of t…
