Semiclassical gravity describes the effective interactions of quantum matter with classical gravity at scales between those of classical and quantum gravity. It offers important insights but also highlights tensions in gravity-quantum unification. Important predictions rely on semiclassical gravity arguments, such black hole radiation (and evaporation) and the formation of structure in cosmology.

However, the mathematical and conceptual foundations of semiclassical gravity are poorly understood. This PhD project will support the goals of EPSRC Fellowship Grant EP/Y014510/1 in carrying out a rigorous study of the foundations of this theory, using state-of-the-art mathematical techniques in quantum physics and gravity, and characterising semiclassical gravity's regime of applicability with full precision.

You will be working with Dr Benito A Juárez Aubry and Prof Chris Fewster in the Department of Mathematics.
