A non-perturbative theory of effective Hamiltonians: example of moiré materials
F. Rost, R. Gupta, M. Fleischmann +7
We demonstrate that there exists a continuum Hamiltonian that is formally the operator equivalent of the general tight-binding method, inheriting the associativi…

Electron-phonon scattering and in-plane electric conductivity in twisted bilayer graphene
N. Ray, M. Fleischmann, D. Weckbecker +3
We have surveyed the in-plane transport properties of the graphene twist bilayer using (i) a low-energy effective Hamiltonian for the underlying electronic structure, (ii) an isotr…

Going beyond k.p theory: a general method for obtaining effective Hamiltonians in both high and low symmetry situations
N. Ray, F. Rost, D. Weckbecker +5
We provide a method for the generation of effective continuum Hamiltonians that goes beyond the well known k.p method in being equally effective in both high, and low (or no) symme…
