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…
Higher-Order Topological Superconductivity in Twisted Bilayer Graphene
Aaron Chew, Yijie Wang, B. Andrei Bernevig +1
We show that introducing spin-singlet or spin-triplet superconductivity into twisted bilayer graphene induces higher-order topological superconductivity. -protected corner…
Survival of the fractional Josephson effect in time-reversal-invariant topological superconductors
Christina Knapp, Aaron Chew, Jason Alicea
Time-reversal-invariant topological superconductor (TRITOPS) wires host Majorana Kramers pairs that have been predicted to mediate a fractional Josephson effect with periodici…
