The Klein-Gordon equation in the spacetime of a charged and rotating black hole
V. B. Bezerra, H. S. Vieira, André A. Costa
This work deals with the influence of the gravitational field produced by a charged and rotating black hole (Kerr-Newman spacetime) on massive scalar fields. We obtain an exact sol…
On Solving Manufacturing Cell Formation via Bicluster Editing
Rian G. S. Pinheiro, Ivan C. Martins, Fábio Protti +3
This work investigates the Bicluster Graph Editing Problem (BGEP) and how it can be applied to solve the Manufacturing Cell Formation Problem (MCFP). We develop an exact method for…
Finite temperature fermionic condensate and currents in topologically nontrivial spaces
S. Bellucci, E. R. Bezerra de Mello, A. A. Saharian
We investigate the finite temperature fermionic condensate and the expectation values of the charge and current densities for a massive fermion field in a spacetime background with…
Kink-antikink collisions for twin models
A. R. Gomes, R. Menezes, K. Z. Nobrega +1
In this work we consider kink-antikink collisions for some classes of -dimensional nonlinear models. We are particularly interested to investigate in which aspect the presen…
A Note on Asymmetric Thick Branes
D. Bazeia, R. Menezes, Roldao da Rocha
In this work we study asymmetric thick braneworld scenarios, generated after adding a constant to the superpotential associated to the scalar field. We study in particular models w…
Interfaces with internal structures in generalized rock-paper-scissors models
P. P. Avelino, D. Bazeia, L. Losano +2
In this work we investigate the development of stable dynamical structures along interfaces separating domains belonging to enemy partnerships, in the context of cyclic predator-pr…
Remarks about the correspondence between and Brans-Dicke gravity
J. P. Morais Graça, Valdir B. Bezerra
We discuss the correspondence between metric gravity and Brans-Dicke theory with a potential, by working out an example that reconfirms this equivalence.
On the effective potential, Horava-Lifshitz-like theories and finite temperature
C. F. Farias, M. Gomes, J. R. Nascimento +2
We calculate the one-loop effective potential at finite temperature for the Horava-Lifshitz-like QED and Yukawa-like theories for arbitrary values of the critical exponent and the…
Deformed self-dual magnetic monopoles
D. Bazeia, R. Casana, M. M. Ferreira +2
We develop a deformation method for attaining new magnetic monopole analytical solutions consistent with generalized Yang-Mills-Higgs model introduced recently. The new solutions f…
Quadratic Palatini gravity and stable black hole remnants
Francisco S. N. Lobo, Gonzalo J. Olmo, D. Rubiera-Garcia
We present a four-dimensional Planck-scale corrected quadratic extension of General Relativity (GR) where no a priori relation between metric and connection is imposed (Palatini fo…
Planck scale physics and topology change through an exactly solvable model
Francisco S. N. Lobo, Jesus Martinez-Asencio, Gonzalo J. Olmo +1
We consider the collapse of a charged radiation fluid in a Planck-suppressed quadratic extension of General Relativity (GR) formulated à la Palatini. We obtain exact analytical sol…
From Brans-Dicke gravity to a geometrical scalar-tensor theory
T. S. Almeida, M. L. Pucheu, C. Romero +1
We consider an approach to Brans-Dicke theory of gravity in which the scalar field has a geometrical nature. By postulating the Palatini variation, we find out that the role played…
Fermionic vacuum polarization in compactified cosmic string spacetime
S. Bellucci, E. R. Bezerra de Mello, A. de Padua +1
We investigate the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor for a charged massive fermionic field in the geometry of a cosmic…
Electric Polarization Induced by Gravity in Fat Branes
F. Dahia, Alex de Albuquerque Silva, C. Romero
In the fat brane model, also known as the split fermion model, it is assumed that leptons and baryons live in different hypersurfaces of a thick brane in order to explain the proto…
Horava-Lifshitz Gravity Effects on Casimir Energy in Weak Field Approximation and Infrared Regime
C. R. Muniz, V. B. Bezerra, M. S. Cunha
We calculate the renormalized vacuum energy of a massless scalar field confined between two nearby parallel plates formed by ideal uncharged conductors, placed tangentially to the…
Braneworld solutions for F(R) models with non-constant curvature
D. Bazeia, A. S. Lobao, R. Menezes +2
This work deal with braneworld scenarios with generalized gravity. We investigate models where the potential of the scalar field is polynomial or nonpolynomial. We obtain exact and…
Optimal Hardy-Littlewood type inequalities for polynomials and multilinear operators
Nacib Albuquerque, Frédéric Bayart, Daniel Pellegrino +1
In this paper we obtain quite general and definitive forms for Hardy-Littlewood type inequalities. Moreover, when restricted to the original particular cases, our approach provides…
Geonic black holes and remnants in Eddington-inspired Born-Infeld gravity
Gonzalo J. Olmo, D. Rubiera-Garcia, Helios Sanchis-Alepuz
We show that electrically charged solutions within the Eddington-inspired Born-Infeld theory of gravity replace the central singularity by a wormhole supported by the electric fiel…
Radiation trapping and Lévy flights in atomic vapours: an introductory review
Martine Chevrollier
Multiple scattering is a process in which a particle is repeatedly deflected by other particles. In an overwhelming majority of cases, the ensuing random walk can successfully be d…

Weliton S. Martins, Thierry Passerat de Silans, Marcos Oriá +1
We demonstrate and interpret a technique of laser-induced formation of thin metallic films using alkali atoms on the window of a dense-vapour cell. We show that this intriguing pho…
