Back-reaction in canonical analogue black holes
Stefano Liberati, Giovanni Tricella, Andrea Trombettoni
We study the back-reaction associated with Hawking evaporation of an acoustic canonical analogue black hole in a Bose-Einstein condensate. We show that the emission of Hawking radi…
The information loss problem: an analogue gravity perspective
Stefano Liberati, Giovanni Tricella, Andrea Trombettoni
Analogue gravity can be used to reproduce the phenomenology of quantum field theory in curved spacetime and in particular phenomena such as cosmological particle creation and Hawki…
Towards a Gordon form of the Kerr spacetime
Stefano Liberati, Giovanni Tricella, Matt Visser
It is not currently known how to put the Kerr spacetime metric into the so-called Gordon form, although the closely related Kerr-Schild form of the Kerr metric is well known. A Gor…
Vorticity in analogue spacetimes
Stefano Liberati, Sebastian Schuster, Giovanni Tricella +1
Analogue spacetimes can be used to probe and study physically interesting spacetime geometries by constructing, either theoretically or experimentally, some notion of an effective…
