Topological phases of graphene-Kagome systems
A. B. Felix de Souza, L. Spreafico, D. Faria +1
The growing skill in the synthesis processes of new materials has intensified the interest in exploring the properties of systems modeled by more complex lattices. Two-dimensional…
Switching valley filtered current directions in multi-terminal graphene systems
Vanessa Torres, Daiara Faria, Andrea Latgé
Valley filtering processes have been explored in different graphene-based configurations and scenarios to control transport responses. Here we propose graphene multi-terminal set-u…
Valley polarization braiding in strained graphene
D. Faria, C. León, L. R. F. Lima +2
Previous works on deformed graphene predict the existence of valley-polarized states, however, optimal conditions for their detection remain challenging. We show that in the quantu…
Gap engineering in strained fold-like armchair graphene nanoribbons
V. Torres, C. Leon, D. Faria +1
Strain fold-like deformations on armchair graphene nanoribbons (AGNRs) can be properly engineered in experimental setups, and could lead to a new controlling tool for gaps and tran…
Tuning the pseudospin polarization of graphene by a pseudo-magnetic field
Alexander Georgi, Peter Nemes-Incze, Ramon Carrillo-Bastos +16
One of the intriguing characteristics of honeycomb lattices is the appearance of a pseudo-magnetic field as a result of mechanical deformation. In the case of graphene, the Landau…
Strained fold assisted transport in graphene systems
R. Carrillo-Bastos, C. León, D. Faria +3
Deformations in graphene systems are central elements in the novel field of {\it straintronics}. Various strain geometries have been proposed to produce specific properties but the…
Induced Matter Brane Gravity and Einstein Static Universe
Y. Heydarzade, F. Darabi
We investigate stability of the Einstein static universe against the scalar, vector and tensor perturbations in the context of induced matter brane gravity. It is shown that in the…
Fano resonances in hexagonal zigzag graphene rings under external magnetic flux
D. Faria, R. Carrillo-Bastos, N. Sandler +1
We study transport properties of hexagonal zigzag graphene quantum rings connected to semi-infinite nanoribbons. Open two-fold symmetric structures support localized states that ca…
Demonstrations of magnetic phenomena: Measuring the air permeablity using tablets
Vitor O. M. Lara, Dayanne F. Amaral, Daiara Faria +1
We use a tablet to determine experimentally the dependencies of the magnetic field (B) on the electrical current and on the axial distance from a coil (z). Our data shows a good pr…
Gaussian deformations in graphene ribbons: flowers and confinement
R. Carrillo-Bastos, D. Faria, A. Latgé +2
The coupling of geometrical and electronic properties is a promising venue to engineer conduction properties in graphene. Confinement added to strain allows for interplay of differ…
Currents and pseudomagnetic fields in strained graphene rings
D. Faria, A. Latge, S. E. Ulloa +1
We study the effects of strain on the electronic properties and persistent current characteristics of a graphene ring using the Dirac representation. For a slightly deformed graphe…
