Black hole analogues in two-dimensional flows with constant shear
Alessia Biondi, Scott Robertson, Germain Rousseaux
We investigate the gravitational analogy for shallow water waves propagating on a unidirectional background flow with constant shear. Generalizing the standard irrotational treatme…

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…

Vortical scattering channel in an aquatic space-time
Alessia Biondi, Scott Robertson, Germain Rousseaux
Effective field theory descriptions of surface waves on flowing fluids have tended to assume that the flow is irrotational, but this assumption is often impractical due to boundary…
