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…
Moiré edge states in twisted graphene nanoribbons
M. Fleischmann, R. Gupta, D. Weckbecker +4
The edge physics of graphene based systems is well known to be highly sensitive to the atomic structure at the boundary, with localized zero mode edge states found only on the zigz…
