Phase transitions in one-dimensional Hubbard model with degeneracy
A. V. Vedyaev, M. E. Zhuravlev, V. A. Ivanov
Abstract:
A solution in quadratures of the doubly orbitally degenerate Hubbard chain with
strong correlations of the electrons in one orbital is obtained by means of the
spin-symmetrized Bethe–Gaudin–Yaug ansatz. The correlation gap in the
dielectric phase is due to both interorbital Coulomb repulsion of the electrons
and their Hund exchange interaction. The possibilities of a Mort transition are
investigated.
