Superconducting gap symmetry of the noncentrosymmetric superconductor W3Al2C
R. Gupta, T. P. Ying, Y. P. Qi +2
A detailed zero-field and transverse-field muon spin relaxation/rotation (SR) experiemnts have been carried out on the recently discovered non-centrosymmetric superconductor W$_…
Superconducting subphase and substantial Knight shift in
R. Gupta, T. Saunderson, S. Shallcross +3
Recent nuclear magnetic resonance experiments measuring the Knight shift in have challenged the widely accepted picture of chiral pairing in this superconductor. Here w…
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…
A general relation between stacking order and Chern index: a topological map of minimally twisted bilayer graphene
S. Theil, M. Fleischmann, R. Gupta +4
We derive a general relation between the stacking vector describing the relative shift of two layers of bilayer graphene and the Chern index. We find $C = ν- \text{sign}\…
