Engineered Near-Perfect Back-Scattering on Surface of Topological Insulator with Non-Magnetic Impurities
J. Fransson, A. M. Black-Schaffer, A. V. Balatsky
We show how to engineer enhanced skew scattering and gap-like opening in the surface state of three-dimensional topological insulators using only non-magnetic impurities. Enhanced…
Unconventional proximity-induced superconductivity in bilayer systems
Fariborz Parhizgar, Annica M. Black-Schaffer
We study the proximity-induced superconducting state in a general bilayer -- conventional -wave superconductor hybrid structure. For the bilayer we include a general parabolic d…
Spontaneous gap generation on the surface of weakly interacting topological insulators using nonmagnetic impurities
Annica M. Black-Schaffer, Dmitry Yudin
Strong nonmagnetic impurities on the surface of three-dimensional topological insulators (TIs) generate localized resonance peaks close to the Dirac point. We show that this result…
Chiral d-wave superconductivity on the honeycomb lattice close to the Mott state
Annica M. Black-Schaffer, Wei Wu, Karyn Le Hur
We study superconductivity on the honeycomb lattice close to the Mott state at half-filling. Due to the sixfold lattice symmetry and disjoint Fermi surfaces at opposite momenta, we…
Chiral d-wave superconductivity in doped graphene
Annica M. Black-Schaffer, Carsten Honerkamp
A highly unconventional superconducting state with a spin-singlet -wave, or chiral d-wave, symmetry has recently been proposed to emerge from electron-elect…
Dirac materials
T. O. Wehling, A. M. Black-Schaffer, A. V. Balatsky
A wide range of materials, like d-wave superconductors, graphene, and topological insulators, share a fundamental similarity: their low-energy fermionic excitations behave as massl…
