  A new two-dimensional black hole model, based on the "R=T" relativistic
theory, is introduced, and the quantum massless scalar field is studied in its
classical gravitational field. In particular infrared questions are discussed.
The two-point function, energy-momentum tensor, current, Bogoliubov
transformations and the mean number of created particles for a given test
function are computed. I show that this black hole emits massless scalar
particles spontaneously. Comparison with the corresponding field theory in a
thermal bath shows that the spontaneous emission is everywhere thermal, i.e.
not only near the horizon.
