Emergent spacetimes
Silke Weinfurtner
We discuss the possibility that spacetime geometry may be an emergent phenomenon. This idea has been motivated by the Analogue Gravity programme. These are systems where the kinema…

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…

Effective refractive index tensor for weak field gravity
Petarpa Boonserm, Celine Cattoen, Tristan Faber +2
Gravitational lensing in a weak but otherwise arbitrary gravitational field can be described in terms of a 3 x 3 tensor, the "effective refractive index". If the sources generating…
