Phase diagram of two-orbital model in one-dimensional and T ~0 including Jahn-Teller phonons, obtained with Monte Carlo techniques [[90]]. S-F labels a spin-ferromagnetic configuration. O-F, O-AF, and O-D denote a state where the orbital degrees of freedom are ordered uniformly, staggered or they are disordered, respectively; PS indicates a phase separated state, and AF in an antiferromagnetic state. The Hund-coupling is JH = 8, the Heisenberg coupling between localized classical spins JAF = 0.05, both in units of the hopping amount the same orbitals.
