Abstract
Using the exact Bethe ansatz solution, a one-dimensional correlated electron system coupled to the lattice is considered. Electrons belonging to two orbital bands interact via the exchange coupling. It is shown that the coupling to the lattice strains can produce a phase transition to the state in which the degeneracy in the orbital filling is removed. In such a state the formation of superconducting correlations is enhanced. The influence of the external magnetic field on the transition is studied.
