Magnetic-field response of generalized Wigner crystals in twisted MoTe
F. K. Wolff, S. Jiao, H. Park +9
We report a magnetotransport study of fractional hole-filling states in the layer-polarized regime of a twisted MoTe homobilayer. A perpendicular magnetic field suppresses the…
HyperDet Wavefunction: A Phase-Agnostic Ansatz for Strongly Correlated Systems
Xiaodong Hu, Guan-Lin Lin, Ying Ran +1
Competing phases of strongly correlated systems are often described by trial wavefunctions built on phase-specific assumptions. We propose the \emph{hyperdeterminant (HyperDet) wav…
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…
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…
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…
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…
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…
Hyperdeterminants and Composite fermion States in Fractional Chern Insulators
Xiaodong Hu, Di Xiao, Ying Ran
Fractional Chern insulators (FCI) were proposed theoretically about a decade ago. These exotic states of matter are fractional quantum Hall states realized when a nearly flat Chern…
Disorder in the non-linear anomalous Hall effect of -symmetric Dirac fermions
Rhonald Burgos Atencia, Di Xiao, Dimitrie Culcer
The study of the non-linear anomalous Hall effect (NLAHE) in -symmetric systems has focussed on intrinsic mechanisms. Here we show that disorder contributes…
