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…

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…
