New non-perturbative de Sitter vacua in -complete cosmology
Carmen A. Núñez, Facundo Emanuel Rost
The -complete cosmology developed by Hohm and Zwiebach classifies the invariant theories involving metric, -field and dilaton that only depend on…
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}\…
