Altermagnetic Routes to Majorana Modes in Zero Net Magnetization
Sayed Ali Akbar Ghorashi, Taylor L. Hughes, Jennifer Cano
We propose heterostructures that realize first and second order topological superconductivity with vanishing net magnetization by utilizing altermagnetism. Such platforms may offer…
Chiral model of twisted bilayer graphene realized in a monolayer
Valentin Crépel, Aaron Dunbrack, Daniele Guerci +2
We demonstrate that a single layer of graphene subject to a superlattice potential nearly commensurate to a supercell exactly maps to the chiral model of…
Intrinsically-multilayer moiré heterostructures
Aaron Dunbrack, Jennifer Cano
We introduce trilayer and multilayer moiré heterostructures that cannot be viewed from the ``moiré-of-moiré" perspective of helically-twisted trilayer graphene. These ``intrinsical…
Multilayer graphene with a superlattice potential
Sayed Ali Akbar Ghorashi, Jennifer Cano
Bernal stacked bilayer graphene subject to a superlattice potential can realize topological and stacked flat bands [1]. In the present work, we extend the study of a superlattice p…
Real space representation of topological system: twisted bilayer graphene as an example
Jiawei Zang, Jie Wang, Antoine Georges +2
We construct a Wannier basis for twisted bilayer graphene that is projected only from the Bloch functions of the twisted bilayer flat bands. The and symme…
Symmetry indicators in commensurate magnetic flux
Yuan Fang, Jennifer Cano
We derive a framework to apply topological quantum chemistry in systems subject to magnetic flux. We start by deriving the action of spatial symmetry operators in a uniform magneti…
