The Quantum Affine Origin of the AdS/CFT Secret Symmetry
Marius de Leeuw, Vidas Regelskis, Alessandro Torrielli
We find a new quantum affine symmetry of the S-matrix of the one-dimensional Hubbard chain. We show that this symmetry originates from the quantum affine superalgebra U_q(gl(2|2)),…
Coideal Quantum Affine Algebra and Boundary Scattering of the Deformed Hubbard Chain
Marius de Leeuw, Takuya Matsumoto, Vidas Regelskis
We consider boundary scattering for a semi-infinite one-dimensional deformed Hubbard chain with boundary conditions of the same type as for the Y=0 giant graviton in the AdS/CFT co…
The Bound State S-matrix of the Deformed Hubbard Chain
Marius de Leeuw, Takuya Matsumoto, Vidas Regelskis
In this work we use the q-oscillator formalism to construct the atypical (short) supersymmetric representations of the centrally extended Uq (su(2|2)) algebra. We then determine th…
