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…
Color-suppression of non-planar diagrams in bosonic bound states
J. H. Alvarenga Nogueira, Chueng-Ryong Ji, E. Ydrefors +1
We study the suppression of non-planar diagrams in a scalar QCD model of a meson system in space-time dimensions due to the inclusion of the color degrees of freedom. As a pr…
Relativistic quantum dynamics of scalar bosons under a full vector Coulomb interaction
Luis B. Castro, Luiz P. de Oliveira, Marcelo G. Garcia +1
The relativistic quantum dynamics of scalar bosons in the background of a full vector coupling (minimal plus nonminimal vector couplings) is explored in the context of the Duffin-K…
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…
