On the conformal limit of a QED-inspired model
O Oliveira, T Frederico, W de Paula
A conformal invariant QED-inspired model is solved for a general covariant linear gauge using the Dyson-Schwinger equations for the propagators assuming a pure vector like interact…
Axion stars in MGD background
R. Casadio, R. da Rocha
The minimal geometric deformation (MGD) paradigm is here employed to survey axion stars on fluid branes. The finite value of the brane tension provides beyond-general relativity co…
Hamiltonian analysis and positivity of a new massive spin-2 model
Alessandro L. R. dos Santos, Denis Dalmazi, Wayne de Paula
Recently a new model has been proposed to describe free massive spin-2 particles in dimensions in terms of a non symmetric rank-2 tensor and a mixed symmetry tensor $B…
Supersymmetry and Fermionic Modes in an Oscillon Background
R. A. C. Correa, L. P. R. Ospedal, W. de Paula +1
The excitations referred to as oscillons are long-lived time-dependent field configurations which emerge dynamically from non-linear field theories. Such long-lived solutions are o…
Configurational Entropy as a tool to select a physical Thick Brane Model
M. Chinaglia, W. T. Cruz, R. A. C. Correa +2
We analise braneworld scenarios via a configurational entropy (CE) formalism. Braneworld scenarios have drawn attention mainly due to the fact that they can explain the hierarchy p…
Motivations for AdS/QCD from 10D supergravity solutions
Wayne de Paula
We discuss some attempts for the construction of gravity duals of QCD-like theories. It is analysed some properties of solutions of 10D Type IIB supergravity theory that attempt to…
Lorentz Violation and Topologically Trapped Charge Carriers in 2D Materials
R. A. C. Correa, W. de Paula, A. de Souza Dutra +1
The full spectrum of two-dimensional fermion states in a scalar soliton trap with a Lorentz breaking background is investigated in the context of the novel 2D materials, where the…
Cosmological scenarios from multiquintessence
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +2
In this work we derive and analyse cosmological scenarios coming from multi-component scalar field models. We consider a direct sum of a sine-Gordon with a Z2 model, and also a com…
Advances in solving the two-fermion homogeneous Bethe-Salpeter equation in Minkowski space
W. de Paula, T. Frederico, G. Salmè +1
Actual solutions of the Bethe-Salpeter equation for a two-fermion bound system are becoming available directly in Minkowski space, by virtue of a novel technique, based on the so-c…
Configurational entropy as a bounding of Gauss-Bonnet braneworld models
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +2
Configurational entropy has been revealed as a reliable method for constraining some parameters of a given model [Phys. Rev. D \textbf{92} (2015) 126005, Eur. Phys. J. C \textbf{76…
On Exact Symmetries and Massless Vectors in Holographic Flows and other Flux Vacua
Massimo Bianchi, Wayne de Paula
We analyze the isometries of Type IIB flux vacua based on the Papadopolous-Tseytlin ansatz and identify the related massless bulk vector fields. To this end we devise a general ans…
