N=2 supersymmetric radiation damping problem on a noncommutative plane
Everton M. C. Abreu, Albert C. R. Mendes, Wilson Oliveira
It is well known that a direct Lagrangian description of radiation damping is still missing. In this paper a specific approach of this problem was used, which is the standard way t…
Hidden symmetries in the two-dimensional isotropic antiferromagnet
S. A. Leonel, A. C. R. Mendes, W. Oliveira +2
We discuss the two-dimensional isotropic antiferromagnet in the framework of gauge invariance. Gauge invariance is one of the most subtle useful concepts in theoretical physics, si…
Symmetry considerations on radiation damping
Everton M. C. Abreu, Albert C. R. Mendes, Wilson Oliveira
It is well known that a direct Lagrangian description of radiation damping is still missing. In this paper we will use a specific approach of this problem which is the standard way…
Analytical and numerical analysis of a rotational invariant D=2 harmonic oscillator in the light of different noncommutative phase-space configurations
Everton M. C. Abreu, Mateus V. Marcial, Albert C. R. Mendes +1
In this work we have investigated some properties of classical phase-space with symplectic structures consistent, at the classical level, with two noncommutative (NC) algebras: the…
QCD gauge symmetries through Faddeev-Jackiw symplectic method
Everton M. C. Abreu, Albert C. R. Mendes, Clifford Neves +2
The interactions between gluons are important in theories such as quantum chromodynamics. Therefore, to rediscover new features of well known methods in order to investigate the SU…
Obtaining gauge invariant actions via symplectic embedding formalism
E. M. C. Abreu, J. Ananias Neto, A. C. R. Mendes +2
The concept of gauge invariance is one of the most subtle and useful concepts in modern theoretical physics. It is one of the Standard Model cornerstones. The main benefit due to t…
