Modified black hole solution with a background Kalb-Ramond field
L. A. Lessa, J. E. G. Silva, R. V. Maluf +1
We study the gravitation effects on a static and spherically symmetric spacetime due to the vacuum expectation value (VEV) of a Kalb-Ramond field. The Kalb-Ramond VEV is a backgrou…
Bipartite-Finsler symmetries
J. E. G. Silva, R. V. Maluf, C. A. S. Almeida
In this work, we study the symmetries of a Lorentz violating bipartite-Finsler spacetime. By using the Finslerian Killing equation for the bipartite-Finsler metric, we analyze how…
The Casimir effect for the scalar and Elko fields in a Lifshitz-like field theory
R. V. Maluf, D. M. Dantas, C. A. S. Almeida
In this work, we obtain the Casimir energy for the real scalar field and the Elko neutral spinor field in a field theory at a Lifshitz fixed point (LP). We analyze the massless and…
Maxwell electrodynamics modified by a CPT-odd dimension-five higher-derivative term
Manoel M. Ferreira, Letícia Lisboa-Santos, Roberto V. Maluf +1
In this paper, we consider an electrodynamics of higher derivatives coupled to a Lorentz-violating background tensor. Specifically, we are interested in a dimension-five term of th…
