Analogue models of gravity are physical systems that, in certain regimes, behave identically as gravitational systems. As shown by Unruh, fluid perturbations satisfy the same equations that a scalar field in a curved spacetime satisfy. This analogy predicts that typical gravitational phenomena, like Hawking radiation and superradiance, can be observed in Hydrodynamics or Condensed Matter. Recent experiments confirm this prediction. This Msc project will introduce the student to the field of Analogue Models of Gravity, with emphasis to the Hawking effect and the superradiant scattering. The final aim is to apply the aquired knowledge to a new problem in the field. (AU)
