Query: Elementary Excitations in the Symmetric Spin--Orbital Model   Possible types of elementary excitations in the symmetric spin-orbital model
on the a square lattice are analyzed using a spherically symmetric
self-consistent approach. The excitation spectra are calculated. The behavior
of the corresponding correlation functions depending on the temperature and
parameters of the model is studied. A schematic phase diagram is plotted. It is
shown that the thermodynamics of the system is mainly determined by elementary
excitations with the entangled spin and orbital degrees of freedom.
