On the Coupling of Matter and Gravity to the Boundary of Space-Time
arXiv:2407.01259
Abstract
We show that under certain boundary conditions on the matter fields and on the fluctuations of the background metric the gravity-matter system can be coupled to the boundary of space-time through the stress-energy tensor. The connection of the formalism developed to the Casimir effect is discussed.
