Realization of Topological Mott Insulator in a Twisted Bilayer Graphene Lattice Model
Bin-Bin Chen, Yuan Da Liao, Ziyu Chen +4
Magic-angle twisted bilayer graphene has recently become a thriving material platform realizing correlated electron phenomena taking place within its topological flat bands. Severa…
Correlated Insulating Phases in the Twisted Bilayer Graphene
Yuan Da Liao, Xiao Yan Xu, Zi Yang Meng +1
We review analytical and numerical studies of correlated insulating states in twisted bilayer graphene, focusing on real-space lattice models constructions and their unbiased quant…
Towards the hidden symmetry in Coulomb interacting twisted bilayer graphene: renormalization group approach
Oskar Vafek, Jian Kang
We develop a two stage renormalization group which connects the continuum Hamiltonian for twisted bilayer graphene at length scales shorter than the moire superlattice period to th…
Topological and nematic superconductivity mediated by ferro-SU(4) fluctuations in twisted bilayer graphene
Yuxuan Wang, Jian Kang, Rafael M. Fernandes
We propose an SU(4) spin-valley-fermion model to investigate the superconducting instabilities of twisted bilayer graphene (TBG). In this approach, bosonic fluctuations associated…
Correlation-induced insulating topological phases at charge neutrality in twisted bilayer graphene
Yuan Da Liao, Jian Kang, Clara N. Breiø +5
Twisted bilayer graphene (TBG) provides a unique framework to elucidate the interplay between strong correlations and topological phenomena in two-dimensional systems. The existenc…
Non-Abelian Dirac node braiding and near-degeneracy of correlated phases at odd integer filling in magic angle twisted bilayer graphene
Jian Kang, Oskar Vafek
We use the DMRG to study the correlated electron states favored by the Coulomb interaction projected onto the narrow bands of twisted bilayer graphene within a spinless one-valley…
