Cascade of fractional quantum Hall states in 2D system
Zhimou Chen, Jiaojie Yan, Yuxuan Zhu +11
The observation of the fractional quantum Hall (FQH) effect in 2D electron gases ushered in investigations of topological phases driven by strong electron correlations. Their remar…
Correlated Quantum Phenomena in Confined Two-Dimensional Hexagonal Crystals
Xiang Liua, Zheng Taoa, Wenchen Luoa +1
Low-energy fermionic excitations in two-dimensional materials deviate from the conventional Schrödinger description and are instead governed by Dirac equations. Such Dirac fermions…
Skin effect in Non-Hermitian systems with spin
Wenna Zhang, Yutao Hu, Hongyi Zhang +6
The skin effect, where bulk modes collapse into boundary modes, is a key phenomenon in topological non-Hermitian systems, has been predominantly studied in spinless systems. Recent…
Interlayer excitons in double-layer transition metal dichalcogenides quantum dots
Xiang Liu, Zheng Tao, Wenchen Luo +1
Various properties of interlayer excitons in double-layer transition metal dichalcogenides quantum dots are analyzed using a low-energy effective Hamiltonian with Coulomb interacti…
fractional quantum Hall state in GaAs with Landau level mixing
Wenchen Luo, Muaath Abdulwahab, Xiang Liu +1
The Landau level mixing is the key in understanding the mysterious fractional quantum Hall effect in GaAs quantum well. Theoretical calculations with and without Landau level…
