Algebraic Bethe Ansatz for spinor R-matrices
Vidas Regelskis
Abstract
We present a supermatrix realisation of q q -deformed spinor-spinor and spinor-vector R R -matrices. These R R -matrices are then used to construct transfer matrices for U_{q^2}(\mathfrak{so}_{2n+1}) U q 2 ( 𝔰 𝔬 2 n + 1 ) - and U_{q}(\mathfrak{so}_{2n+2}) U q ( 𝔰 𝔬 2 n + 2 ) -symmetric closed spin chains. Their eigenvectors and eigenvalues are computed.
