introduction
- how to identify the standard objects of quantum integrable systems (transfer matrices, Baxter's \(Q\)-operators, etc.) with elements of classical nonlinear integrable difference equations (\(\tau\)-functions, Baker-Akhiezer functions, etc.).
dictionary
- The functional relation for commuting quantum transfer matrices of quantum integrable models is shown to coincide with the classical Hirota bilinear difference equation.
- This equation is equivalent to the completely discretized classical 2D Toda lattice with open boundaries.
- Elliptic solutions of Hirota's equation give a complete set of eigenvalues of the quantum transfer matrices.
- The elliptic solutions relevant to the Bethe ansatz are studied.
- The nested Bethe ansatz equations for \(A_{k−1}\)-type models appear as discrete time equations of motions for zeros of classical \(\tau\)-functions and Baker-Akhiezer functions.
- Determinant representations of the general solution to the bilinear discrete Hirota equation are analysed and a new determinant formula for eigenvalues of the quantum transfer matrices is obtained.
Baxter \(Q\)-operator
- Eigenvalues of Baxter's \(Q\)-operator are solutions to the auxiliary linear problems for the classical Hirota equation.
- Difference equations for eigenvalues of the \(Q\)-operators which generalize Baxter's three-term \(T-Q\)-relation are derived
- Hirota bilinear method
- T-system
- Determinant solutions of T-systems
- Octahedral recurrence
- Difference L-operators and TT-relations
