Localized Excitons and Landau-Level Mixing in Time-Reversal Symmetric Pairs of Chern Bands
Guopeng Xu, Nemin Wei, Inti Sodemann Villadiego +1
We study Landau-level mixing in a time-reversal-symmetric Hamiltonian composed of two sets of Landau levels with opposite magnetic field, relevant to moiré minibands in twisted hom…

Topological excitonic insulators in electron bilayers modulated by twisted hBN
Yongxin Zeng, Allan H. MacDonald, Nemin Wei
Equilibrium interlayer exciton condensation is common in bilayer quantum Hall systems and is characterized by spontaneous phase coherence between isolated layers. It has been predi…
