Atomically Sharp Internal Interface in a Chiral Weyl Semimetal Nanowire
Nitish Mathur, Fang Yuan, Guangming Cheng +7
Internal interfaces in Weyl semimetals (WSMs) are predicted to host distinct topological features that are different from the commonly studied external interfaces (crystal-to-vacuu…
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…
Emergent flat band and topological Kondo semimetal driven by orbital-selective correlations
Lei Chen, Fang Xie, Shouvik Sur +4
Flat electronic bands are expected to show proportionally enhanced electron correlations, which may generate a plethora of novel quantum phases and unusual low-energy excitations.…
Higher-Order Nodal Hinge States in Doped Superconducting Topological Insulator
Sayed Ali Akbar Ghorashi, Jennifer Cano, Enrico Rossi +1
Doped strong topological insulators are one of the most promising candidates to realize a fully gapped three-dimensional topological superconductor (TSC). In this letter, we revisi…
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…
