THE DUAL EMBEDDING METHOD IN D = 3

- E. Abreu, A. Mendes, C. Neves, W. Oliveira, F. Takakura, L. M. Xavier
- Physics
- 7 March 2007

Improving the beginning steps of a previous work, we settle the dual embedding method (DEM) as an alternative and efficient method for obtaining dual equivalent actions also in D = 3. We show that we… Expand

Metafluid dynamics as a gauge field theory

- A. Mendes, W. Oliveira, C. Neves, F. Takakura
- Physics
- 11 September 2001

In this paper, the analog of Maxwell electromagnetism for hydrodynamic turbulence, the metafluid dynamics, is extended in order to reformulate the metafluid dynamics as a gauge field theory. That… Expand

The effect of singular potentials on the harmonic oscillator

- C. Filgueiras, E. Silva, W. Oliveira, F. Moraes
- Physics
- 1 November 2010

Abstract We address the problem of a quantum particle moving under interactions presenting singularities. The self-adjoint extension approach is used to guarantee that the Hamiltonian is self-adjoint… Expand

Weyl ordering prescription for the quantum particle on the D-dimensional sphere

- J. Neto, W. Oliveira
- Physics
- 24 November 1998

The energy eigenvalues of the quantum particle constrained in a surface of the sphere of D dimensions embedded in a $R^{D+1}$ space are obtained by using two different procedures: in the first, we… Expand

QCD gauge symmetries through Faddeev-Jackiw symplectic method

- E. Abreu, A. Mendes, C. Neves, W. Oliveira, R. C. Silva
- Physics, Mathematics
- 22 April 2013

A bstractThe 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(3) gauge… Expand

Clebsch parameterization from the symplectic point of view [rapid communication]

- C. Neves, W. Oliveira
- Physics, Mathematics
- 7 October 2003

This Letter proposes an alternative systematic way to obtain a canonical Lagrangian formulation for rotational systems. This will be done in the symplectic framework and with the introduction of… Expand

Supersymmetrization of radiation damping

- A. Mendes, W. Oliveira, C. Neves, F. Takakura
- Physics
- 16 May 2005

We construct a supersymmetrized version of the model to the radiation damping introduced by the present authors (Mendes, Neves, Oliveira and Takakura 2005 Preprint hep-th/0503135). We discuss its… Expand

EQUIVALENCE BETWEEN DIFFERENT CLASSICAL TREATMENTS OF THE O(N) NONLINEAR SIGMA MODEL AND THEIR FUNCTIONAL SCHRÖDINGER EQUATIONS

- A. Deriglazov, W. Oliveira, G. Oliveira-Neto
- Physics
- 16 January 2002

In this work we derive the Hamiltonian formalism of the O(N) nonlinear sigma model in its original version as a second-class constrained field theory and then as a first-class constrained field… Expand

Ju l 2 01 3 Symmetry considerations on radiation damping

- E. Abreu, A. Mendes, W. Oliveira
- 2013

Abstract 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 to treat… Expand
