Incommensurate-Stabilized Fractional Chern Insulator in Alternating Twisted Trilayer Graphene
Moru Song, Kai Chang
Fractional Chern insulators (FCIs) typically emerge in topological flat bands and are regarded as lattice analogs of fractional quantum Hall states. Conventionally, the flat-band w…

Emergence of Cascading Flat Bands in Breathing Superlattices
Moru Song, Jingyu Hu, Lina Shi +2
Flat bands have become a pillar of modern condensed matter physics and photonics owing to the vanishing group velocity and diverging density of states. Here, we present a paradigma…

Fractional Chern Insulators Transition in Non-ideal Flat Bands of Twisted Mono-bilayer Graphene
Moru Song, Kai Chang
Fractional Chern insulators (FCIs) in ideal flat bands with Chern number are commonly understood as color-entangled states constructed from copies of the lowest Landau leve…
