Is particle creation by the gravitational field consistent with energy conservation?

High Energy Physics - Theory 2007-05-23 v1 General Relativity and Quantum Cosmology

Abstract

If particle creation is described by a Bogoliubov transformation, then, in the Heisenberg picture, the raising and lowering operators are time dependent. On the other hand, this time dependence is not consistent with field equations and the conservation of the stress-energy tensor. Possible physical interpretations and resolutions of this inconsistency are discussed.
