Decomposing Fractional Quantum Hall Wave Functions via Operator Contraction Multiplication
Dong-Hao Guan, Licheng Wang, Yuan Zhou +2
We develop a general algebraic scheme to decompose fractional quantum Hall (FQH) wave functions based on the operator contraction multiplication. By introducing fermionic and boson…
A Sc2C2@C88 cluster based ultra-compact multi-level probabilistic bit for matrix multiplication
Haoran Qi, Guohao Xi, Yuan-Biao Zhou +19
Information units are progressively approaching the fundamental physical limits of the integration density, including in terms of extremely small sizes, multistates and probabilist…
Alternative -picture of bosonic fractional Chern insulators at high filling factors in multiple flat-band systems
Licheng Wang, Dong-Hao Guan, Ai-Lei He +2
Most fractional quantum Hall states have been traditionally identified within a single energy band, such as the lowest Landau level or topological flat band. As more particles are…
Magnetically tuned topological phase in graphene nanoribbon heterojunctions
Wei-Jian Li, Da-Fei Sun, Sheng Ju +2
The interplay between topology and magnetism often triggers the exotic quantum phases. Here, we report an accessible scheme to engineer the robust topology by intr…
Topological flat bands in hyperbolic lattices
Dong-Hao Guan, Lu Qi, Yuan Zhou +2
Topological flat bands (TFBs) provide a promising platform to investigate intriguing fractionalization phenomena, such as the fractional Chern insulators (FCIs). Most of TFB models…
