An algebraic approach to the Hubbard model [PDF]
Phys. Lett. A. 380 (2016) 645-653, 2015 We study the algebraic structure of an integrable Hubbard-Shastry type lattice model associated with the centrally extended su(2|2) superalgebra. This superalgebra underlies Beisert's AdS/CFT worldsheet R-matrix and Shastry's R-matrix. The considered model specializes to the one-dimensional Hubbard model in a certain limit.

Coideal Quantum Affine Algebra and Boundary Scattering of the Deformed Hubbard Chain [PDF]
J.Phys.A A45 (2012) 065205, 2011 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 correspondence. We show that the recently constructed quantum affine algebra of the deformed Hubbard chain has a coideal subalgebra which is consistent with the reflection ...

Nested algebraic Bethe ansatz for open spin chains with even twisted Yangian symmetry [PDF]
Ann. Henri Poincare 20 (2019), 339-392, 2017 We present a nested algebraic Bethe ansatz for a one dimensional open spin chain whose boundary quantum spaces are irreducible $\mathfrak{so}_{2n}$- or $\mathfrak{sp}_{2n}$-representations and the monodromy matrix satisfies the defining relations of the Olshanskii twisted Yangian $Y^\pm(\mathfrak{gl}_{2n})$.

Nested algebraic Bethe ansatz for orthogonal and symplectic open spin chains [PDF]
, 2019 We present a nested algebraic Bethe ansatz for one-dimensional open so(2n)- and sp(2n)-symmetric spin chains with diagonal boundary conditions and described by the extended twisted Yangian. We use a generalization of the Bethe ansatz introduced by De Vega and Karowski which allows us to relate the spectral problem of a so(2n)- or sp(2n)-symmetric open ...

Nested algebraic Bethe ansatz for deformed orthogonal and symplectic spin chains [PDF]
, 2019 We construct exact eigenvectors and eigenvalues for $U_q(\mathfrak{sp}_{2n})$- and $U_q(\mathfrak{so}_{2n})$-symmetric closed spin chains by means of a nested algebraic Bethe ansatz method. We use a fusion procedure to construct higher-dimensional Lax operators.
