Super-WZNW with reductions to supersymmetric and fermionic integrable models
(Elsevier B.V., 2009-11-11)
A systematic construction for an action describing a class of supersymmetric integrable models as well as for pure fermionic theories is discussed in terms of the gauged WZNW model associated to half integer graded affine ...
Type-II super-Backlund transformation and integrable defects for the N=1 super sinh-Gordon model
(Springer, 2015-06-18)
A new super-Backlund transformation for the N = 1 supersymmetric sinhGordon equation is constructed. Based on this construction we propose a type-II integrable defect for the supersymmetric sinh-Gordon model consistent ...
Soliton spectrum of integrable models with local symmetries
(2002-07-01)
The soliton spectrum (massive and massless) of a family of integrable models with local U(1) and U(1) ⊗U(1) symmetries is studied. These models represent relevant integrable deformations of SL(2,ℝ) ⊗U(1) n-1-WZW and SL(2,ℝ) ...
The concept of quasi-integrability for modified non-linear Schrodinger models
(SPRINGERNEW YORK, 2012)
We consider modifications of the nonlinear Schrodinger model (NLS) to look at the recently introduced concept of quasi-integrability. We show that such models possess an in finite number of quasi-conserved charges which ...
Integrability vs supersymmetry: Poisson structures of the pohlmeyer reduction
(Springer, 2011-11-01)
We construct recursively an infinite number of Poisson structures for the supersymmetric integrable hierarchy governing the Pohlmeyer reduction of superstring sigma models on the target spaces AdS(n) x S(n), n = 2, 3, 5. ...
Some properties of (3+1) dimensional vortex solutions in the extended CPN Skyrme-Faddeev model
(Societa Italiana di Fisica - SIFBologna, 2011-12)
We look at properties of vortex solutions of the extended CPN Skyrme-Faddeev model. We show that only holomorphic solutions of the CPN model are also solutions of the Skyrme-Faddeev model. As the total energy of these ...
Numerical and analytical tests of quasi-integrability in modified sine-Gordon models
(SpringerHeidelberg, 2014-01)
Following our attempts to define quasi-integrability in which we related this concept to a particular symmetry of the two-soliton function we check this condition in three classes of modified sine-Gordon models in (1+1) ...
N=1 super sinh-Gordon model with defects revisited
(Springer, 2015-02-26)
The Lax pair formalism is considered to discuss the integrability of the N = 1 supersymmetric sinh-Gordon model with a defect. We derive associated defect matrix for the model and construct the generating functions of the ...
Supersymmetry flows, semi-symmetric space sine-Gordon models and the Pohlmeyer reduction
(Springer, 2011-03-01)
We study the extended supersymmetric integrable hierarchy underlying the Pohlmeyer reduction of superstring sigma models on semi-symmetric superspaces F/G. This integrable hierarchy is constructed by coupling two copies ...
