Zero modes and geometric phase for 2D Weyl fermions on Lifshitz backgrounds
G. Q. Garcia, D. C. Moreira, E. Cavalcante +1
Here we investigate analytical properties of Weyl fermions in (2+1)-dimensional Lifshitz spacetimes. In particular, we are interested in obtaining geometric phases and verifying th…
Geometric Modeling of a Line of Alternating Disclinations: Application to Grain Boundaries in Graphene
A. M. de M. Carvalho, C. Furtado
We develop a conformal geometric model for grain boundaries in graphene based on a periodic line of alternating disclinations. Within the framework of (2+1)-dimensional gravity, we…
Geometric and Topological Aspects of Quadrupoles of Disclinations: Conformal Metrics and Self-Forces
A. M. de M. Carvalho, G. Q. Garcia, C. Furtado
We study the geometric and physical effects of quadrupolar configurations of disclinations using a conformal metric approach in dimensions. Two cases are considered: a line…
Contribution of Geometry and Non-Abelian Gauge Fields to Aharonov-Bohm Scattering of Massless Fermions in Graphene with Disclinations
M. J. Bueno, G. Q. Garcia, A. M. de M. Carvalho +1
This work examines the effect of disclinations on the scattering of quasipaticles in graphene with the presence of a topological defect. Using the tight-binding method, the electro…
