Naturalness in emergent spacetime
Stefano Liberati, Matt Visser, Silke Weinfurtner
Effective field theories (EFTs) have been widely used as a framework in order to place constraints on the Planck suppressed Lorentz violations predicted by various models of quantu…
Combining rotation curves and gravitational lensing: How to measure the equation of state of dark matter in the galactic halo
Tristan Faber, Matt Visser
We argue that combined observations of galaxy rotation curves and gravitational lensing not only allow the deduction of a galaxy's mass profile, but also yield information about th…
Analogue model for quantum gravity phenomenology
Silke Weinfurtner, Stefano Liberati, Matt Visser
So called "analogue models" use condensed matter systems (typically hydrodynamic) to set up an "effective metric" and to model curved-space quantum field theory in a physical syste…
Analogue quantum gravity phenomenology from a two-component Bose-Einstein condensate
Stefano Liberati, Matt Visser, Silke Weinfurtner
We present an analogue spacetime model that reproduces the salient features of the most common ansatz for quantum gravity phenomenology. We do this by investigating a system of two…
Necessary and sufficient conditions for big bangs, bounces, crunches, rips, sudden singularities, and extremality events
Celine Cattoen, Matt Visser
The physically relevant singularities occurring in FRW cosmologies had traditionally been thought to be limited to the "big bang", and possibly a "big crunch". However, over the la…
Massive Klein--Gordon equation from a BEC-based analogue spacetime
Matt Visser, Silke Weinfurtner
We extend the "analogue spacetime" programme by investigating a condensed-matter system that is in principle capable of simulating the massive Klein--Gordon equation in curved spac…
