Baxter Q-operators from a Schwinger-Boson construction of the master T-operator and the mKP hierarchy
Zengo Tsuboi
The master T-operator is a generating function for transfer matrices and a tau-function of the modified KP (mKP) hierarchy. It is conventionally introduced through a Schur-function…
Character Formulas for Kirillov-Reshetikhin Modules via Folding of Supercharacters of
Zengo Tsuboi
We derive decomposition formulas for supercharacters of quantum affine ortho-symplectic superalgebras and twisted quantum affine superalgebras into supercharacters of their finite-…
Boson-Fermion correspondence, QQ-relations and Wronskian solutions of the T-system
Zengo Tsuboi
It is known that there is a correspondence between representations of superalgebras and ordinary (non-graded) algebras. Keeping in mind this type of correspondence between the twis…
Folding QQ-relations and transfer matrix eigenvalues: towards a unified approach to Bethe ansatz for super spin chains
Zengo Tsuboi
Extending the method proposed in [arXiv:1109.5524], we derive QQ-relations (functional relations among Baxter Q-functions) and T-functions (eigenvalues of transfer matrices) for fu…
