Stacking-Induced Large-Chern-Number Quantum Anomalous Hall Phases
H. Minh Lam, V. Nam Do
We investigate the interaction between quantum anomalous Hall (QAH) phases hosted by two atomically thin hexagonal lattices and demonstrate the emergence of topological phases with…
Optical activity and transport in twisted bilayer graphene: the essence of spatial dispersion effects
S. Ta Ho, V. Nam Do
This study investigates optical activity and quantum transport in twisted bilayer graphene (TBG) systems, demonstrating that the former results from spatial dispersion effects. The…
A brief review of mathematical foundation for analyzing topological characteristics of quantum electronic states and matter phases
V. Nam Do
We briefly review the advanced mathematical language of fiber bundle structures and how they can be used to classify two-level quantum systems based on the analysis of the topologi…
Theory for constructing effective models for electrons in generic bilayer graphene
H. Minh Lam, V. Nam Do
We present and discuss in detail practical techniques in formulating effective models to describe the dynamics of low-energy electrons in generic bilayer graphene. Starting from a…
Chiral correlation of drag currents inducing optical activity of twisted bilayer graphene
S. Ta Ho, V. Nam Do
The mechanisms of optical activity and quantum transport of twisted bilayer graphene are studied. The formation of unique electron states in the bilayer systems is studied using an…
Electronic band crossing in sliding bilayer graphene: Tight-binding calculations and symmetry group representation analysis
V. Nam Do
Dirac points are found to emerge due to the crossing of bands in the electronic structure of bilayer graphene for configurations in which the alignment between two hexagonal lattic…
