Signature-change events in emergent spacetimes with anisotropic scaling
Silke Weinfurtner, Angela White, Matt Visser
We investigate the behaviour of quantum fields coupled to a spacetime geometry exhibiting finite regions of Euclidean (Riemannian) signature. Although from a gravity perspective th…

Trans-Planckian physics and signature change events in Bose gas hydrodynamics
Silke Weinfurtner, Angela White, Matt Visser
We present an example of emergent spacetime as the hydrodynamic limit of a more fundamental microscopic theory. The low-energy, long-wavelength limit in our model is dominated by c…

Asymptotics of the dispersion interaction: analytic benchmarks for van der Waals energy functionals
John F. Dobson, Angela White, Angel Rubio
We show that the usual sum of contributions from elements separated by distance can give \emph{qualitatively} wrong results for the electromagnetically non-retarded va…
