Genuine tripartite entanglement in Bhabha scattering with an entangled spectator particle
Zan Cao, Meng-Long Song, Xue-Ke Song +2
From the perspective of quantum information science, we investigate tree-level Bhabha scattering between an incident electron and a positron , where is initially entangl…
Tunable high-Chern-number Chern insulators in rhombohedral tetralayer graphene/hBN moiré superlattices
Chuanqi Zheng, Chushan Li, Ke Huang +17
Moiré superlattices based on rhombohedral multilayer graphene have emerged as a highly tunable platform for engineering correlated topological phases. Here, we systematically inve…
Moire driven edge reconstruction in Fractional quantum anomalous Hall states
Feng Liu, Hoi Chun Po, Xue-Yang Song
We investigate fractional edge modes in moire fractional quantum anomalous Hall states, focusing on the role of lattice momentum conservation and umklapp scattering. For the hierar…
Universal electrical transport of composite Fermi liquid to Metal transition in Moiré systems
Youxuan Wang, Rongning Liu, Feng Liu +1
We compute universal electrical transport near continuous transitions between a composite Fermi liquid (CFL) and a metallic phase in moire Chern bands, focusing on fillings $ν=-1/…
