Integrable model of bosons in a four-well ring with anisotropic tunneling
A. P. Tonel, L. H. Ymai, A. Foerster +1
We introduce an integrable, four-well ring model for bosons where the tunneling couplings between nearest-neighbour wells are not restricted to be equal. We show how the model may…
Grassmanian and Bosonic Thirring Models with Jump Defects
A. R. Aguirre, J. F. Gomes, L. H. Ymai +1
In this paper we discuss the Lax formulation of the Grassmanian and Bosonic Thirring models in the presence of jump defects. For the Grassmanian case, the defect is described by Bä…
Nonautonomous mixed mKdV-sinh-Gordon hierarchy
J. F. Gomes, G. R. de Melo, L. H. Ymai +1
The construction of a nonautonomous mixed mKdV/sine-Gordon model is proposed by employing an infinite dimensional affine Lie algebraic structure within the zero curvature represent…
Thirring Model with Jump Defect
A. R. Aguirre, J. F. Gomes, L. H. Ymai +1
The purpose of our work is to extend the formulation of classical affine Toda Models in the presence of jump defects to pure fermionic Thirring model. As a first attempt we constru…
Permutability of Backlund Transformations for N=2 Supersymmetric Sine-Gordon
J. F. Gomes, L. H. Ymai, A. H. Zimerman
The permutability of two Backlund transformations is employed to construct a non linear superposition formula and to generate a class of solutions for the N=2 super sine-Gordon mod…
A Class of Soliton Solutions for the N=2 Super mKdV/Sinh-Gordon Hierarchy
H. Aratyn, J. F. Gomes, L. H. Ymai +1
Employing the Hirota's method, a class of soliton solutions for the N=2 super mKdV equations is proposed in terms of a single Grassmann parameter. Such solutions are shown to satis…
