Exact self-consistent gravitational shock wave in semiclassical gravity
We find a self-consistent [Formula presented]-gravitational shock wave solution to the semiclassical Einstein equations resulting from the [Formula presented] approach to the effective action. We model the renormalized matter stress-energy-momentum tensor by [Formula presented] massless scalar field...
