Final Activity Report Summary - ANALOGUE GRAVITY (Gravitational physics from the analogue gravity perspective)
The main outcome of this one-year period has been the publication of an extensive review article (to appear in 'Living Reviews on Relativity') on analogue gravity. In this article, it is described the present state of the art of the research area pointing out which are in our view the most interesting problems to be addressed now on. We (me and my collaborators) have tried to write the article in a manner as pedagogical as possible, making the article useful as an introduction to the field for new graduate students.
Apart from this article, I have published another paper analysing the causal properties of a catalogue of spacetime geometries containing horizons selected because their naturalness from the point of view of acoustic systems. These geometries are from the point of view of acoustics equivalent to the characterisation of different black holes by their mass and charge. The analysis on this paper provide new insights about the most appropriate ways to reproduce different aspects of black hole physics in laboratory. In addition, it shows from a condensed matter perspective what is the meaning of analytical extensions of geometry.
