Query: Lattice Landau gauge gluon propagator at finite temperature: non-zero
  Matsubara frequencies and spectral densities   The lattice Landau gauge gluon propagator at finite temperature is computed
including the non-zero Matsubara frequencies. Furthermore, the
K\"all\'en-Lehmann representation is inverted and the corresponding spectral
density evaluated using a Tikhonov regularisation together with the Morozov
discrepancy principle. Implications for gluon confinement are discussed.
