Query: On the relativistic KMS condition for the P(\phi)_2 model   The relativistic KMS condition introduced by Bros and Buchholz provides a
link between quantum statistical mechanics and quantum field theory. We show
that for the $P(\phi)_2$ model at positive temperature, the two point function
for fields satisfies the relativistic KMS condition.
