We investigate the quantum integrability of the Landau–Lifshitz (LL) model and solve the long-standing problem of finding the local quantum Hamiltonian for the arbitrary n-particle sector. The particular difficulty of the LL model quantization, which arises due to the ill-defined operator product, is dealt with by simultaneously regularizing the operator product and constructing the self-adjoint extensions of a very particular structure. The diagonalizibility difficulties of the Hamiltonian of… 

Thermodynamics of the quantum su(1, 1) Landau–Lifshitz model

We present the thermodynamics of the quantum su(1, 1) Landau–Lifshitz model, following our earlier exposition of the quantum integrability of the theory, which is based on the construction of

It is shown, following the analogous computations for the non-linear Schrodinger model, that the three-particle S-matrix is factorizable in the first non-trivial order.
