This article will summarize selected aspects of the semiclassical theory of gravity, which involves a classical gravitational field coupled to quantum matter fields. Among the issues which will be discussed are the role of quantum effects in black hole physics and in cosmology, the effects of quantum violations of the classical energy conditions, and inequalities which constrain the extent of such violations. We will also examine the first steps beyond semiclassical gravity, when the effects of spacetime geometry fluctuations start to appear.

  1. Structure and statistical properties of the semiclassical Einstein equations

    gr-qc 2024-12 conditional novelty 6.0 of 10

    Two standard derivations of semiclassical gravity are equivalent as partial classical limits, so the equation predicts only the expectation value of the Einstein tensor.

  2. Casimir Effect in Stochastic Semi-Classical Gravity

    quant-ph 2025-01 reject novelty 2.0 of 10

    The paper rederives the known Fermi-coordinate gravitational correction to the Casimir force, F/A = -g E_C, but does not derive the claimed stochastic semi-classical gravity correction.
