Multi-Point Affine Bialgebras for AdS/CFT Integrability
Niklas Beisert, Egor Im, Hannes Malcha
In this work, we revisit the analytical structure of the classical affine Lie bialgebra underlying the integrable structures of AdS/CFT worldsheet scattering and the one-dimensiona…
Yangian Symmetry Escapes from the Fishnet
Niklas Beisert, Benedikt König
We investigate Yangian symmetry for the equations of motion and the action of the classical bi-scalar and supersymmetric fishnet models in four spacetime dimensions, and we subsequ…
Yangian Form-alism for Planar Gauge Theories
Niklas Beisert, Benedikt König
In this article, we reconsider the formulation of Yangian symmetry for planar N=4 supersymmetric Yang-Mills theory, and we investigate to what extent this symmetry lifts to the bet…
Infinite-Length Limit of Spectral Curves and Inverse Scattering
Niklas Beisert, Kunal Gupta
Integrability equips models of theoretical physics with efficient methods for the exact construction of useful states and their evolution. Relevant tools for classical integrable f…
Affine Classical Lie Bialgebras for AdS/CFT Integrability
Niklas Beisert, Egor Im
In this article we continue the classical analysis of the symmetry algebra underlying the integrability of the spectrum in the AdS_5/CFT_4 and in the Hubbard model. We extend the c…
Classical Lie Bialgebras for AdS/CFT Integrability by Contraction and Reduction
Niklas Beisert, Egor Im
Integrability of the one-dimensional Hubbard model and of the factorised scattering problem encountered on the worldsheet of AdS strings can be expressed in terms of a peculiar qua…
