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…
A Quantum Affine Algebra for the Deformed Hubbard Chain
Niklas Beisert, Wellington Galleas, Takuya Matsumoto
The integrable structure of the one-dimensional Hubbard model is based on Shastry's R-matrix and the Yangian of a centrally extended sl(2|2) superalgebra. Alcaraz and Bariev have s…
