New results on twinlike models
D. Bazeia, R. Menezes
In this work we study the presence of kinks in models described by a single real scalar field in bidimensional spacetime. We work within the first-order framework, and we show how…
Twinlike Models for Self-Dual Maxwell-Higgs Theories
D. Bazeia, E. da Hora, R. Menezes
In this work we present a theoretical framework that allows for the existence of coherent twinlike models in the context of self-dual Maxwell-Higgs theories. We verify the consiste…
Conductance peaks in open quantum dots
J. G. G. S. Ramos, D. Bazeia, M. S. Hussein +1
We present a simple measure of the conductance fluctuations in open ballistic chaotic quantum dots, extending the number of maxima method originally proposed for the statistical an…
Presence of asymmetric noise in multi-terminal chaotic cavities
A. L. R. Barbosa, J. G. G. S. Ramos, D. Bazeia
This work deals with chaotic quantum dot connected to two and four leads. We use standard diagrammatic procedure to integrate on the unitary group, to study the main term in the se…
Spin Accumulation Encoded in Electronic Noise for Mesoscopic Billiards with Finite Tunneling Rates
J. G. G. S. Ramos, A. L. R. Barbosa, D. Bazeia +1
We study the effects of spin accumulation (inside reservoirs) on electronic transport with tunneling and reflections at the gates of a quantum dot. Within the stub model, the calcu…
Twinlike Models in Scalar Field Theories
D. Bazeia, J. D. Dantas, A. R. Gomes +2
This work deals with the presence of defect structures in models described by real scalar field in a diversity of scenarios. The defect structures which we consider are static solu…
3D black holes on a 2-brane in 4D Minkowski space
D. Bazeia, F. A. Brito, F. G. Costa
We investigate three-dimensional black hole solutions in the realm of pure and new massive gravity in 2+1 dimensions induced on a 2-brane embedded in a flat four-dimensional spacet…
Multi-sine-Gordon Models
D. Bazeia, L. Losano, J. M. C. Malbouisson +1
This work deals with the presence of defect structures in generalized sine-Gordon models. The models are described by periodic potentials, with substructure having one, two, three…
Compact vortex in a generalized Born-Infeld model
D. Bazeia, E. da Hora, D. Rubiera-Garcia
We study vortexlike solutions in a generalized Born-Infeld model. The model is driven by two distinct parameters, one which deals with the Born-Infeld term, and the other, which co…
Crossover of thermal to shot noise in chaotic cavities
A. L. R. Barbosa, J. G. G. S. Ramos, D. Bazeia
We study the crossover between thermal and shot-noise power in a chaotic quantum dot in the presence of non-ideal contacts at finite temperature. The result explicitly demonstrates…
New scalar field models and their defect solutions
D. Bazeia, M. A. Gonzalez Leon, L. Losano +1
In this work we introduce new scalar field models and study the defect solutions they may engender. The investigation is based on the deformation procedure, which greatly simplify…
