Phase transitions of bosonic fractional quantum Hall effect in topological flat bands
Tian-Sheng Zeng
We study the phase transitions of bosonic fractional quantum Hall (FQH) effect in different topological lattice models under the interplay of onsite periodic potential and…
Bosonic Halperin fractional quantum Hall effect at filling factor
Tian-Sheng Zeng, Liangdong Hu, W. Zhu
Quantum Hall effects with multicomponent internal degrees of freedom facilitate the playground of novel emergent topological orders. Here, we explore the correlated topological pha…
Quantum Hall effects of exciton condensate in topological flat bands
Tian-Sheng Zeng, D. N. Sheng, W. Zhu
Tunable exciton condensates in two dimensional electron gas systems under strong magnetic field exhibits anomalous Hall transport owing to mutual Coulomb coupling, and have attract…
Continuous phase transition between bosonic integer quantum Hall liquid and trivial insulator: evidences for deconfined quantum criticality
Tian-Sheng Zeng, D. N. Sheng, W. Zhu
The deconfined quantum critical point, a prototype Landau-forbidden transition, could exist in principle in the phase transitions involving symmetry protected topological phase, ho…
Topological characterization of hierarchical fractional quantum Hall effects in topological flat bands with SU() symmetry
Tian-Sheng Zeng, D. N. Sheng, W. Zhu
We study the many-body ground states of SU() symmetric hardcore bosons on the topological flat-band model by using controlled numerical calculations. By introducing strong intra…
Quantum Anomalous Hall Phase Stabilized via Realistic Interactions on a Kagome Lattice
Yafei Ren, T. -S. Zeng, W. Zhu +1
We study the quantum phases of spinless fermion at one-third filling on a Kagome lattice featuring a quadratic band touching Fermi point. In the presence of weak first and second n…
