Fractional Mimetic Dark Matter Model in Fractional Action-like Variational Approach
C. F. L. Godinho, I. V. Vancea
In this paper, we propose a new model of fractional mimetic dark matter based on the fractional action-like variational approach FALVA implementation of fractionality. The model is…
Gravitoelectromagnetic knot fields
Adina Crisan, Cresus Godinho, Ion Vancea
We construct a class of knot solutions of the gravitoelectromagnetic (GEM) equations in vacuum in the linearized gravity approximation by analogy with the Rañada-Hopf fields. For t…
Variational Procedure for Higher-Derivative Mechanical Models in a Fractional Integral Framework
C. F. L. Godinho, Nelson Panza, J. A. Helayël Neto
We present both the Lagrangian and Hamiltonian procedures for treating higher-order equations of motion for mechanical models by adopting the Riemann-Liouville Fractional integral…
Extension and Applications of a Variational Approach with Deformed Derivatives
J. Weberszpil, J. A. Helayël-Neto
We have recently presented an extension of the standard variational calculus to include the presence of deformed derivatives in the Lagrangian of a system of particles and in the L…
Gauge invariant actions for the noncommutative phase-space relativistic particle
Everton M. C. Abreu, Cresus F. L. Godinho
Our main interest here is to analyze the gauge invariance issue concerning the noncommutative relativistic particle. Since the analysis of the constraint set from Dirac's point of…
Torsion Effects and LLG Equation
Cristine N. Ferreira, Cresus F. L. Godinho, J. A. Helayël Neto
Based on the non-relativistic regime of the Dirac equation coupled to a torsion pseudo-vector, we study the dynamics of magnetization and how it is affected by the presence of tors…
