Moiré metals and continuum models beyond a single valley
Matthew Albert, Andrew Klekovkin-Hardy, Valentin Crépel
We derive continuum models of moiré materials valid over the full monolayer Brillouin zone, as required for metals whose large Fermi surfaces are not confined to a single valley. T…
Dispersion of Anyon Bloch Bands
Kishore Iyer, Andreas Feuerpfeil, Valentin Crépel +2
Fractional Chern insulators (FCIs) are zero magnetic field analogs of fractional quantum Hall states. While the electrons forming an FCI are not subject to an external magnetic fie…
High-throughput discovery of moiré homobilayers guided by topology and energetics
Naoto Nakatsuji, Jennifer Cano, Valentin Crépel
Van der Waals heterostructures promise on-demand designer quantum phases through control of monolayer composition, stacking, twist angle, and external fields. Yet, experimental eff…
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…
