Perfect and controllable nesting in the small angle twist bilayer graphene
Maximilian Fleischmann, Reena Gupta, Florian Wullschläger +5
Parallel ("nested") regions of a Fermi surface (FS) drive instabilities of the electron fluid, for example the spin density wave in elemental chromium. In one-dimensional materials…
Deformation induced pseudo-magnetic fields in complex carbon architectures
R. Gupta, S. Maisel, F. Rost +6
We show that the physics of deformation in -, -, and -graphyne is, despite their significantly more complex lattice structures, remarkably close to that of graphene,…
Moiré ordered current loops in the graphene twist bilayer
D. Weckbecker, M. Fleischmann, R. Gupta +6
While a typical material exhibits field induced currents only at the boundary, a uniform out-of-plane magnetic field applied to two mutually rotated layers of graphene is shown to…
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…
Dislocation and node states in bilayer graphene systems
D. Weckbecker, R. Gupta, F. Rost +2
We investigate the electronic structure of realistic partial dislocation networks in bilayer graphene that feature annihilating, wandering, and intersecting partial lines. We find…
