Non-uniform quantum geometry stabilizes generalized Wigner crystals
Nicolás Morales-Durán, Tobias M. R. Wolf, Jingtian Shi +3
Moiré materials host fractional Chern insulators and electron crystals in close proximity, but the mechanism selecting between them remains an open question. We address this compet…
Efficient prediction of topological superlattice bands with spin-orbit coupling
M. Nabil Y. Lhachemi, Valentin Crépel, Jennifer Cano
We develop a symmetry indicator framework to efficiently predict the topology of superlattice-induced minibands with spin-orbit coupling. Our algorithm requires input only from the…
Inducing topological flat bands in bilayer graphene with electric and magnetic superlattices
Daniel Seleznev, Jennifer Cano, David Vanderbilt
It was recently argued that Bernal stacked bilayer graphene (BLG) exposed to a 2D superlattice (SL) potential exhibits a variety of intriguing behaviors [Ghorashi et al., Phys. Rev…
Topological Kondo semimetal and insulator in AB-stacked heterobilayer transition metal dichalcogenides
Daniele Guerci, Kevin P. Lucht, Valentin Crépel +3
Recent experiments reported the realization of a heavy Fermi liquid in AB-stacked MoTe/WSe heterobilayers. In this paper we show that the AB-stacked heterobilayer configura…
Efficient prediction of superlattice and anomalous miniband topology from quantum geometry
Valentin Crépel, Jennifer Cano
Two dimensional materials subject to long-wavelength modulations have emerged as novel platforms to study topological and correlated quantum phases. In this article, we develop a v…
