Emergent gravitational dynamics in Bose-Einstein condensates
Lorenzo Sindoni, Florian Girelli, Stefano Liberati
We discuss a toy model for an emergent non-relativistic gravitational theory. Within a certain class of Bose-Einstein condensates, it is possible to show that, in a suitable regime…
Analogue Models for Emergent Gravity
Stefano Liberati, Florian Girelli, Lorenzo Sindoni
Gravity stands out among the fundamental interactions because of its apparent incompatibility with having a quantum description. Moreover, thermodynamic aspects of gravitation theo…
Is the notion of time really fundamental?
Florian Girelli, Stefano Liberati, Lorenzo Sindoni
From the Physics point of view, time is now best described through General Relativity, as part of space-time which is a dynamical object encoding gravity. Time possesses also some…
Gravitational dynamics in Bose Einstein condensates
Florian Girelli, Stefano Liberati, Lorenzo Sindoni
Analogue models for gravity intend to provide a framework where matter and gravity, as well as their intertwined dynamics, emerge from degrees of freedom that have a priori nothing…
On the emergence of Lorentzian signature and scalar gravity
Florian Girelli, Stefano Liberati, Lorenzo Sindoni
In recent years, a growing momentum has been gained by the emergent gravity framework. Within the latter, the very concepts of geometry and gravitational interaction are not seen a…
Quantum reference frames and deformed symmetries
Florian Girelli, David Poulin
In the context of constrained quantum mechanics, reference systems are used to construct relational observables that are invariant under the action of the symmetry group. Upon meas…
