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…
