Tunnelling across a trapped region and out of a black hole
Edward Wilson-Ewing
The quantum field theory for a massless scalar field on a two-dimensional non-singular black hole spacetime gives a non-vanishing probability for a particle to tunnel out of the bl…
Testing ER = EPR with Hydrogen
Irfan Javed, Edward Wilson-Ewing
According to the ER = EPR conjecture, entangled particles are connected by quantum wormholes. Under the assumption that some of the electric field surrounding an entangled charged…
Relational Observables in Group Field Theory
Luca Marchetti, Edward Wilson-Ewing
We construct relational observables in group field theory (GFT) in terms of covariant positive operator-valued measures (POVMs), using techniques developed in the context of quantu…
A low-redshift preference for an interacting dark energy model
Yuejia Zhai, Marco de Cesare, Carsten van de Bruck +2
We explore an interacting dark sector model in trace-free Einstein gravity where dark energy has a constant equation of state, , and the energy-momentum transfer potential is…
Dynamical homogenization in effective loop quantum cosmology
Edward Wilson-Ewing
The effective dynamics of loop quantum gravity for marginally bound Lemaître-Tolman-Bondi spacetimes predict that the big-bang singularity is resolved and replaced by a cosmic bou…
Static Planck stars from effective loop quantum gravity
Edward Wilson-Ewing
Effective loop quantum gravity dynamics are derived for spherically symmetric spacetimes with a perfect fluid matter content. For homogeneous spacetimes, the effective dynamics agr…
