Large scale theoretical investigation of the phase diagram of twisted bilayer MoTe at fractional fillings: agreements and contradictions with current experiments
Heqiu Li, Jiabin Yu, Xiaodong Xu +2
We present a comprehensive exact-diagonalization study of interaction-driven phases in twisted bilayer MoTe across experimentally relevant twist angles (--…
Giant and Helical Exciton Dipole from Berry Curvature in Flat Chern Bands
Kaijie Yang, Huiyuan Zheng, Xiaodong Xu +2
We show that excitons forming between moiré flat Chern bands possess a substantial electric dipole moment comparable to the moiré lattice parameter times the elementary charge ($\s…
Spinless and spinful charge excitations in moiré Fractional Chern Insulators
Miguel Gonçalves, Juan Felipe Mendez-Valderrama, Jonah Herzog-Arbeitman +5
Fractionally charged elementary excitations, the quasi-electron and quasi-hole, are one of the hallmarks of the fractional Chern insulator (FCI). In this work, we observe that spon…
Observation of High-Temperature Dissipationless Fractional Chern Insulator
Heonjoon Park, Weijie Li, Chaowei Hu +13
The fractional quantum anomalous Hall effect has recently been experimentally observed in zero-field fractional Chern insulators (FCI). However, an outstanding challenge is the pre…
When Could Abelian Fractional Topological Insulators Exist in Twisted MoTe (and Other Systems)
Yves H. Kwan, Glenn Wagner, Jiabin Yu +6
Using comprehensive exact diagonalization calculations on twisted bilayer MoTe (MoTe), as well as idealized Landau level models also relevant for…
Ferromagnetism and Topology of the Higher Flat Band in a Fractional Chern Insulator
Heonjoon Park, Jiaqi Cai, Eric Anderson +18
The recent observation of the fractional quantum anomalous Hall effect in moiré fractional Chern insulators provides an opportunity to investigate zero magnetic field anyons. To po…
