Grainger College of Engineering Seminars & Speakers

Analogue models of gravity allow us to test in the laboratory phenomena that occur in regions of space with high curvature. After the seminal paper by Unruh, that showed that sound waves propagating in a fluid perceive an effective curved spacetime, different models have emerged in the context of fluid mechanics. Recent developments in this field led to the first observations of Hawking radiation and superradiance. However, these experiments have also shown that the theoretical models being considered are not enough to describe the systems under study, making it necessary to consider the role played by other effects, such as dispersion and vorticity. In this seminar we will consider the theoretical and experimental advances in the field of gravitational analogs in fluids, focusing on the effect of the vorticity in these models.
