Multiferroicity and Topology in Twisted Transition Metal Dichalcogenides
Ahmed Abouelkomsan, Emil J. Bergholtz, Shubhayu Chatterjee
Van der Waals heterostructures have recently emerged as an exciting platform for investigating the effects of strong electronic correlations, including various forms of magnetic or…
Topological and stacked flat bands in bilayer graphene with a superlattice potential
Sayed Ali Akbar Ghorashi, Aaron Dunbrack, Ahmed Abouelkomsan +3
We show that bilayer graphene in the presence of a 2D superlattice potential provides a highly tunable setup that can realize a variety of flat band phenomena. We focus on two regi…
Quantum Metric Induced Phases in Moiré Materials
Ahmed Abouelkomsan, Kang Yang, Emil J. Bergholtz
We show that, quite generally, quantum geometry plays a major role in determining the low-energy physics in strongly correlated lattice models at fractional band fillings. We ident…
