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…
