Interaction-driven Band Flattening and Correlated Phases in Twisted Bilayer Graphene
Youngjoon Choi, Hyunjin Kim, Cyprian Lewandowski +8
Flat electronic bands, characteristic of magic-angle twisted bilayer graphene (TBG), host a wealth of correlated phenomena. Early theoretical considerations suggested that, at the…
Spin-orbit-enhanced magnetic surface second-harmonic generation in SrIrO
K. L. Seyler, A. de la Torre, Z. Porter +6
An anomalous optical second-harmonic generation (SHG) signal was previously reported in SrIrO and attributed to a hidden odd-parity bulk magnetic state. Here we investigate…
Tracing out Correlated Chern Insulators in Magic Angle Twisted Bilayer Graphene
