Gravitacional field of a global defect
D. Bazeia, C. Furtado, A. R. Gomes
Global topological defects described by real scalar field in (3,1) dimensions coupled to gravity are analyzed. We consider a class of scalar potentials with explicit dependence wit…
First-order formalism and dark energy
D. Bazeia, C. B. Gomes, L. Losano +1
This work deals with cosmological models driven by real scalar field, described by standard dynamics in generic spherical, flat, and hyperbolic geometries. We introduce a first-ord…
Relaxing to a three dimensional brane junction
D. Bazeia, F. A. Brito, L. Losano
We suggest a mechanism which leads to 3+1 space-time dimensions. The Universe assumed to have nine spatial dimensions is regarded as a special nonlinear oscillatory system -- a kin…
Global Defects in Field Theory with Applications to Condensed Matter
D. Bazeia, J. Menezes, R. Menezes
We review investigations on defects in systems described by real scalar fields in (D,1) space-time dimensions. We first work in one spatial dimension, with models described by one…
Deformed defects with applications to braneworlds
D. Bazeia, L. Losano
In this work we investigate two distinct extensions of the deformation procedure introduced in former works on deformed defects. The first extension deals with the use of deformati…
Defect Structures in Field Theory
Dionisio Bazeia
This work contains a set of lectures on defect structures, mainly in models described by scalar fields in diverse dimensions.
Defect Structures in Lorentz and CPT Violating Scenarios
M. N. Barreto, D. Bazeia, R. Menezes
We investigate models described by real scalar fields, searching for defect structures in the presence of interactions which explicitly violate Lorentz and CPT symmetries. We first…
