Spin texture in weak topological insulators: the role of bulk states and band bending
F. Rost, R. Gupta, S. Sharma +2
We derive the spin texture of a weak topological insulator via a supersymmetric approach that includes the roles of the bulk gap edge states and surface band bending. We find the s…
Bulk-to-surface misorientation and the spin texture of topological insulators
N. Klier, F. Rost, R. Gupta +3
Weak topological insulators possess a symmetry related set of Dirac-Weyl cones in the surface Brillouin zone, implying misorientation between the principle axis of the low energy m…
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,…
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…
