Special integrals of motion in quantum integrable systems
S. V. Kryukov
We investigate quantum integrals of motion in the sine-Gordon, Zhiber-Shabat and similar systems. When the coupling constants in these models take special values a new quantum symm…

Notes about equivalence between Sine-Gordon theory (free fermion point) and the free fermion theory
S. V. Kryukov
The space of local integrals of motion for the Sine-Gordon theory (the free fermion point) and the theory of free fermions in the light cone coordinates is investigated. Some impor…
