Abstract
To understand the interplay of spin, orbital and lattice degrees of freedom in colossal magneto-resistance manganites we numerically diagonalize an SU(2) symmetric spin-orbital model coupled to dynamic Jahn-Teller and Holstein-type phonons. For a four site cluster we demonstrate how the coupling to the lattice changes the order of spins, orbitals and charges, and the correlations between them.
