Black hole analogues in two-dimensional flows with constant shear
Alessia Biondi, Scott Robertson, Germain Rousseaux
We review the Analogue Gravity description of a unidirectional water wave system, assuming no prior knowledge of General Relativity or differential geometry. In so doing, we genera…

A diagrammatic approach to correlation functions in superfluids
Alessia Biondi, Maria Luisa Chiofalo, Massimo Mannarelli +1
Renaud Parentani has given a vast contribution to the development of gravitational analogue models as tools to explore various important aspects of general relativity and of quantu…

Effective-Field Theories of Analogue Gravity
Alessia Biondi
We develop a novel method for building a gravitational analog model for a flowing Bose-Einstein condensate. The analogue metric is obtained using effective field theory methods, in…
