Hyperdeterminant wavefunctions
Guan-Lin Lin, Di Xiao, Ying Ran
We systematically introduce hyperdeterminant wavefunctions as a variational-wavefunction-based theoretical framework for strongly correlated quantum states of matter, together with…
Composite Fermion Theory of Fractional Chern Insulator Stability
Xiaodong Hu, Ying Ran, Di Xiao
We develop a mean-field theory of the stability of fractional Chern insulators based on the dipole picture of composite fermions (CFs). We construct CFs by binding vortices to Bloc…
Optical Control of Integer and Fractional Chern Insulators
William Holtzmann, Weijie Li, Eric Anderson +9
Optical control of topology, particularly in the presence of electron correlations, is a fascinating topic with broad scientific and technological impact. Twisted MoTe bilayer…
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…
Hidden States and Dynamics of Fractional Fillings in tMoTe2 Moiré Superlattices
Yiping Wang, Jeongheon Choe, Eric Anderson +14
The fractional quantum anomalous Hall (FQAH) effect was recently discovered in twisted MoTe2 bilayers (tMoTe2). Experiments to date have revealed Chern insulators from hole doping…
