Construction of exact Riemannian instanton solutions
L. Bonora, C. P. Constantinidis, L. A. Ferreira +1
We give the exact construction of Riemannian (or stringy) instantons, which are classical solutions of 2d Yang-Mills theories that interpolate between initial and final string conf…
Confinement and soliton solutions in the SL(3) Toda model coupled to matter fields
A. G. Bueno, L. A. Ferreira, A. V. Razumov
We consider an integrable conformally invariant two dimensional model associated to the affine Kac-Moody algebra SL(3). It possesses four scalar fields and six Dirac spinors. The t…
Infinite symmetries in the Skyrme model
L. A. Ferreira, J. Sanchez-Guillen
We show that the Skyrme theory possesses a submodel with an infinite number of local conserved currents. The constraints leading to the submodel explore a decomposition of SU(2) wi…
Confinement, solitons and the equivalence between the sine-Gordon and massive Thirring models
Harold Blas, L. A. Ferreira
We consider a two-dimensional integrable and conformally invariant field theory possessing two Dirac spinors and three scalar fields. The interaction couples bilinear terms in the…
Exact static soliton solutions of 3+1 dimensional integrable theory with nonzero Hopf numbers
H. Aratyn, L. A. Ferreira, A. H. Zimerman
In this paper we construct explicitly an infinite number of Hopfions (static, soliton solutions with non-zero Hopf topological charges) within the recently proposed 3+1-dimensional…
Integrable theories in any dimension: a perspective
Orlando Alvarez, L. A. Ferreira, J. Sanchez Guillen
We review the developments of a recently proposed approach to study integrable theories in any dimension. The basic idea consists in generalizing the zero curvature representation…
