Threshold singularities in the correlators of the one-dimensional models
A. A. Ovchinnikov
We calculate the threshold singularities in one-dimensional models using the universal low-energy formfactors obtained in the framework of the non-linear Luttinger liquid model. We…

Baxter Q- operator and functional relations
A. A. Ovchinnikov
We obtain the Baxter Q-operators in the invariant integrable models as a special limits of the quantum transfer matrices corresponding to different spins in the a…
