TSTG II: Projected Hartree-Fock Study of Twisted Symmetric Trilayer Graphene
Fang Xie, Nicolas Regnault, Dumitru Călugăru +2
The Hamiltonian of the magic-angle twisted symmetric trilayer graphene (TSTG) can be decomposed into a TBG-like flat band Hamiltonian and a high-velocity Dirac fermion Hamiltonian.…

Open Momentum Space Method for Hofstadter Butterfly and the Quantized Lorentz Susceptibility
Biao Lian, Fang Xie, B. Andrei Bernevig
We develop a generic open momentum space method for calculating the Hofstadter butterfly of both continuum (Moiré) models and tight-binding models, whe…

The Landau Level of Fragile Topology
Biao Lian, Fang Xie, B. Andrei Bernevig
We study the Hofstadter butterfly and Landau levels of the twisted bilayer graphene (TBG). We show that the nontrivial fragile topology of the lowest two bands near the charge neut…
