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…
