Identifier: http://hdl.handle.net/1959.14/1181044
Description: Jacobson's thermodynamic derivation of the Einstein equations was originally applied only to local Rindler horizons. But at least some parts of that construction can usefully be extended to give meani ... More

Identifier: http://hdl.handle.net/1959.14/1192698
Description: We propose an experiment to test the effects of gravity and acceleration on quantum entanglement in space-based setups. We show that the entanglement between excitations of two Bose–Einstein condensat ... More

Description: Even if a probability distribution is properly normalizable, its associated Shannon (or von Neumann) entropy can easily be infinite. We carefully analyze conditions under which this phenomenon can occ ... More

Identifier: http://hdl.handle.net/1959.14/1183134
Description: We discuss the subtle relationship between massive gravity and bimetric gravity, focusing particularly on the manner in which massive gravity may be viewed as a suitable limit of bimetric gravity. The ... More

Identifier: http://hdl.handle.net/1959.14/1184362
Description: We develop the "generalized Gordon ansatz" for the ghost-free versions of both massive and bimetric gravity, an ansatz which is general enough to include almost all spacetimes commonly considered to b ... More

Description: Ever since the work of von Ignatowsky circa 1910 it has been known (if not always widely appreciated) that the relativity principle, combined with the basic and fun- damental physical assumptions of l ... More

Identifier: http://hdl.handle.net/1959.14/1184352
Description: We consider the effective stress-energy tensors for the foreground and background sectors in ghost-free bimetric gravity. By considering the symmetries of the theory, we show that the foreground and b ... More

Identifier: http://hdl.handle.net/1959.14/1183170
Description: We show that N = 1-supersymmetric BF theory in 3D leads to a supersymmetric spin foam amplitude via a lattice discretization. Furthermore, by analysing the supersymmetric quantum amplitudes, we show t ... More
