Ground state energy and topological mass in spacetimes with nontrivial topology
Paulo J. Porfírio, Herondy F. Santana Mota, Gabriel Queiroz Garcia
In the present paper, we investigate the ground state energy of a massless scalar field and generation of topological mass by considering a quasi-periodically identified Minkowski…
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…
Fermions in Gödel-type background space-times with torsion and the Landau quantization
G. Q. Garcia, J. R. de S. Oliveira, K. Bakke +1
In this paper, we analyze Dirac fermions in Gödel-type background space-times with torsion. We also consider the Gödel-type spacetimes embedded in a topological defect background.…
