Nonlinear Schrodinger equation with chaotic, random, and nonperiodic nonlinearity
W. B. Cardoso, S. A. Leao, A. T. Avelar +2
In this paper we deal with a nonlinear Schrödinger equation with chaotic, random, and nonperiodic cubic nonlinearity. Our goal is to study the soliton evolution, with the strength…
Modulation of breathers in cigar-shaped Bose-Einstein condensates
W. B. Cardoso, A. T. Avelar, D. Bazeia
We present new solutions to the nonautonomous nonlinear Schroedinger equation that may be realized through convenient manipulation of Bose-Einstein condensates. The procedure is ba…
Supersymmetric extensions of k-field models
D. Bazeia, R. Menezes, A. Yu. Petrov
We investigate the supersymmetric extension of k-field models, in which the scalar field is described by generalized dynamics. We illustrate some results with models that support s…
New family of sine-Gordon models
D. Bazeia, L. Losano, R. Menezes +1
This work deals with a new family of models, which includes the sine-Gordon model and the double-sine-Gordon, triple-sine-Gordon and so on. The investigation is based on a deformat…
Lump-like Structures in Scalar-field Models
A. T. Avelar, D. Bazeia, W. B. Cardoso +1
In this work we investigate the presence of lump-like solutions in models described by a single real scalar field. We take advantage of a procedure recently used to describe explic…
Extended solutions via the trial-orbit method for two-field models
A. R. Gomes, D. Bazeia
In this work we investigate the presence of defect structures in models described by two real scalar fields. The coupling between the two fields is inspired on the equations for a…
Impact of Lorentz violation on the dynamics of inflation
P. P. Avelino, D. Bazeia, L. Losano +2
This work deals with the dynamics of inflation in the context of a scalar-vector-tensor theory of gravity exhibiting spontaneous Lorentz violation at early times. We describe a fir…
Bright and Dark Solitons in a Periodically Attractive and Expulsive Potential with Nonlinearities Modulated in Space and Time
A. T. Avelar, D. Bazeia, W. B. Cardoso
This work deals with soliton solutions of the nonlinear Schroedinger equation with a diversity of nonlinearities. We solve the equation in a potential which oscillates in time betw…
