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…
