Phys. Rev. D 81, 044039 (2010) [11 pages]Dynamics and entanglement in spherically symmetric quantum gravityReceived 16 March 2009; published 26 February 2010 The gravity-scalar field system in spherical symmetry provides a natural setting for exploring gravitational collapse and its aftermath in quantum gravity. In a canonical approach, we give constructions of the Hamiltonian operator, and of semiclassical states peaked on constraint-free data. Such states provide explicit examples of physical states. We also show that matter-gravity entanglement is an inherent feature of physical states, whether or not there is a black hole. © 2010 The American Physical Society URL:
