Graphene-based topological insulator in the presence of a disclination submitted to a uniform magnetic field
J. R. S. Oliveira, G. Q. Garcia, P. J. Porfírio +1
In this paper we investigate quasiparticles in graphene-based topological insulator with a wedge disclination in the presence of a uniform magnetic field. In particular, we conside…

Graphene wormhole trapped by external magnetic field
G. Q. Garcia, P. J. Porfírio, D. C. Moreira +1
In this work we study the behavior of massless fermions in a graphene wormhole and in the presence of an external magnetic field. The graphene wormhole is made from two sheets of g…

Weyl fermions in a family of Gödel-type geometries with a topological defect
G. Q. Garcia, J. R. de S. Oliveira, Claudio Furtado
In this paper we study Weyl fermions in a family of Gödel-type geometries in Einstein general relativity. We also consider that these solutions are embedded in a topological defect…
