Emergence of Gravitational Potential and Time Dilation from Non-interacting Systems Coupled to a Global Quantum Clock
Ashmeet Singh, Oliver Friedrich
We study gravitational back-reaction within the Page-Wootters formulation of quantum mechanics by treating time as a quantum degree of freedom. Our model introduces a distinction b…

Toolkit for Scalar Fields in Universes with finite-dimensional Hilbert Space
Oliver Friedrich, Ashmeet Singh, Olivier Doré
The holographic principle suggests that the Hilbert space of quantum gravity is locally finite-dimensional. Motivated by this point-of-view, and its application to the observable U…
