Hierarchy of Symmetry Breaking Correlated Phases in Twisted Bilayer Graphene
Robert Polski, Yiran Zhang, Yang Peng +8
Twisted bilayer graphene (TBG) near the magic twist angle of exhibits a rich phase diagram. However, the interplay between different phases and their dependence on tw…
Spectroscopic Signatures of Strong Correlations and Unconventional Superconductivity in Twisted Trilayer Graphene
Hyunjin Kim, Youngjoon Choi, Cyprian Lewandowski +7
Magic-angle twisted trilayer graphene (MATTG) has emerged as a novel moiré material that exhibits both strong electronic correlations and unconventional superconductivity. However,…
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
Youngjoon Choi, Hyunjin Kim, Yang Peng +9
Magic-angle twisted bilayer graphene (MATBG) exhibits a range of correlated phenomena that originate from strong electron-electron interactions. These interactions make the Fermi s…
Superconductivity without insulating states in twisted bilayer graphene stabilized by monolayer WSe
Harpreet Singh Arora, Robert Polski, Yiran Zhang +11
Magic-angle twisted bilayer graphene (TBG), with rotational misalignment close to 1.1, features isolated flat electronic bands that host a rich phase diagram of correlated…
