Effective Lifshitz-Born-Infeld black holes from general covariance breaking
D. C. Moreira, A. S. Lemos, F. A. Brito
In this work we present an effective Lifshitz black hole solution with Born-Infeld electrodynamics and explore some of its properties. We discuss the mechanism for capturing the so…
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…
Effective Lifshitz black holes, hydrodynamics, and transport coefficients in fluid/gravity correspondence
D. C. Moreira, R. da Rocha
Effective Lifshitz black holes with arbitrary dynamical exponent are addressed in the fluid/gravity membrane paradigm. The transport and the response coefficients in the dual Lifsh…

D. C. Moreira, A. S. Lemos, F. A. Brito
In this work we use a general covariance breaking method to obtain a class of topological charged black holes whose background geometry asymptotically approaches Lifshitz spacetime…
Scalar fields and Lifshitz black holes from Derrick's theorem evasion
D. C. Moreira, F. A Brito, J. C. Mota-Silva
We study classical scalar fields in asymptotically Lifshitz spacetimes. By evading Derrick's theorem requiring the scalar potential to explicitly depend on the background coordinat…

D. Bazeia, D. A. Ferreira, D. C. Moreira
This work discuss the construction of braneworld solutions in modified gravity with Lagrange multipliers. We examine the general aspects of the model and present a first order form…

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…
