Fractional Chern insulators in magic-angle twisted bilayer graphene
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +12
Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue toward manipulating non-abelian excitations. Early theoreti…
Thermodynamics of free and bound magnons in graphene
Andrew T. Pierce, Yonglong Xie, Seung Hwan Lee +6
Symmetry-broken electronic phases support neutral collective excitations. For example, monolayer graphene in the quantum Hall regime hosts a nearly ideal ferromagnetic phase at fil…
Unconventional sequence of correlated Chern insulators in magic-angle twisted bilayer graphene
Andrew T. Pierce, Yonglong Xie, Jeong Min Park +11
The interplay between strong electron-electron interactions and band topology can lead to novel electronic states that spontaneously break symmetries. The discovery of flat bands i…
