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…

Efficient prediction of topological superlattice bands with spin-orbit coupling
M. Nabil Y. Lhachemi, Valentin Crépel, Valentin Crépel +1
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…

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…
