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 ...
Integrable theories and loop spaces: fundamentals, applications and new developments
(World Scientific PublishingSingapore, 2009)
We review our proposal to generalize the standard two-dimensional flatness construction
of Lax–Zakharov–Shabat to relativistic field theories in d + 1 dimensions. The fundamentals
from the theory of connections on loop ...
S-matrices and quantum group symmetry of k-deformed sigma models
(2016-10-21)
Recently, two kinds of integrable deformations of the string world sheet theory in the gauge/gravity correspondence have been constructed (Delduc et al 2014 Phys. Rev. Lett. 112 051601; Hollowood et al 2014 J. Phys. A: ...
Some aspects of self-duality and generalised BPS theories
(SpringerHeidelberg, 2013-08)
If a scalar eld theory in (1+1) dimensions possesses soliton solutions obeying rst order BPS equations, then, in general, it is possible to nd an in nite number of related eld theories with BPS solitons which obey closely ...
Spin chain integrability in non-supersymmetric Wilson loops
(Springer, 2018-12)
We study the 1-loop dilatation operator for insertions of composite operators in a generalized Wilson loop in N = 4 super Yang-Mills, which interpolates between the supersymmetric Wilson-Maldacena loop and the ordinary ...
Two-dimensional solutions for Born-Infeld fields
(Springer, 2013-08)
The non-linear second order Born-Infeld equation is reduced to a simpler first order complex equation, which can be trivially solved for the coordinates as functions of the field. Each solution is determined by the choice ...
The concept of quasi-integrability: a concrete example
(SPRINGER, 2011)
We use the deformed sine-Gordon models recently presented by Bazeia et al [1] to take the first steps towards defining the concept of quasi-integrability. We consider one such definition and use it to calculate an infinite ...
Adding flavour to the S-matrix bootstrap
(2018-12-01)
We explore the S-matrices of gapped, unitary, Lorentz invariant quantum field theories with a global O(N) symmetry in 1+1 dimensions. We extremize various cubic and quartic couplings in the two-to-two scattering amplitudes ...
