A fractional quantum Hall factory on quantum processors: constant-depth preparation of clustered non-Abelian states
Cheng Xu, Ching Hua Lee, Hong-Hao Tu +1
Non-Abelian anyons arise as exotic excitations in fractional quantum Hall (FQH) matter and have proved very elusive to realize in conventional platforms. In this work, we show that…
Stable magic angle in twisted Kane-Mele materials
Cheng Xu, Yong Xu, Wenhui Duan +1
We propose that flat bands and van Hove singularities near the magic angle can be stabilized against angle disorder in the twisted Kane-Mele model. With continuum model and maximal…
Multiple Chern bands in twisted MoTe and possible non-Abelian states
Cheng Xu, Ning Mao, Tiansheng Zeng +1
We investigate the moiré band structures and possible even denominator fractional quantum Hall state in small angle twisted bilayer MoTe, using combined large-scale local basis…
Transfer learning relaxation, electronic structure and continuum model for twisted bilayer MoTe
Ning Mao, Cheng Xu, Jiangxu Li +6
Large-scale moiré systems are extraordinarily sensitive, with even minute atomic shifts leading to significant changes in electronic structures. Here, we investigate the lattice re…
Maximally Localized Wannier Orbitals, Interaction Models and Fractional Quantum Anomalous Hall Effect in Twisted Bilayer MoTe2
Cheng Xu, Jiangxu Li, Yong Xu +2
We investigate the moiré band structures and the strong correlation effects in twisted bilayer MoTe for a wide range of twist angles, employing a combination of various techniq…
