Query: Finite Temperature Correlators in the Schwinger Model   We discuss the correlation function of hadronic currents in the Schwinger
model at finite temperature $T$. We explicitly construct the retarded
correlator in real time and obtain analytical results for the Euclidean
correlator on a torus. Both constructions lead to the same finite temperature
spectral function. The spatial screening lengths in the mesonic channels are
related to the dynamical meson mass $m=e/\sqrt{\pi}$ and not $2\pi T$ even in
the infinite temperature limit. The relevance of our results for the finite
temperature problem in four dimensions is discussed.
