We investigate magnetic instabilities in charge-neutral twisted bilayer graphene close to so-
called" magic angles" using a combination of real-space Hartree-Fock and dynamical mean …

Construction of low-energy symmetric Hamiltonians and Hubbard parameters for twisted multilayer systems using ab initio input

A Davydov, K Choo, MH Fischer, T Neupert - Physical Review B, 2022 - APS
A computationally efficient workflow for obtaining the low-energy symmetric tight-binding
Hamiltonians for twisted multilayer systems is presented in this work. We apply this scheme …
