Abstract
We calculate the photon dispersion relations generated by the quark loop in a quark-gluon plasma with the color background condensate = const. It is found that both transversal and longitudinal modes are exited. They have a gap at low momenta and are stable in high temperature approximation. The background fields act as imaginary chemical potentials and decrease the photon frequencies compared to the case of zero background. The comparison with QED plasma with chemical potential is discussed.
