Накратко на български

Аналозите на черните дупки се изследват чрез поведението на вълни в течности, например във водни вълни. Това помага за разбирането на явления от фундаменталната физика и космологията, които в момента са недостъпни за наблюдение в открития космос.

From fluid dynamics to quantum gravity

Since the seminal work of Unruh, it is known that waves propagating in a moving fluid behaves as waves in a gravitational field, and in particular, that of a black hole. This allows us to mimic several black hole phenomena in laboratory setups. The domain exploiting this idea, called ?analogue gravity? has recently undergone a rapid expansion, due to several experimental results in different media, such as water waves, optical fibers or Bose-Einstein condensates. However, these experiments raise many new theoretical questions to be properly understood, as well as to conduct new ones. Understanding and performing such experiments are of great value for fundamental physics. These analogue in fluids allows us to study and observe phenomena that are currently out of reach in astrophysics. Observing them in a fluid confirm there robustness, giving us more confidence it must exist in the universe. But they also give us new insights and hints on the possible difficulties, or new effects that are currently not suspected. The aim of this project was to understand the theoretical aspects of the analogues of black hole effects and cosmology in fluids. We have focused on three main effects: Hawking radiation, black hole superradiance, and particle production in cosmology. The project has not only advanced the theoretical understanding of these effects, but it has also provided an experimental verification of superradiance using water waves.

Цел на проекта

Reconciling general relativity with quantum physics is the Holy Grail of theoretical physics. Today the major physical predictions involving both gravity and quantum fields, in the framework of quantum field theory in curved space-times, are black hole radiation and particle production in an expanding Universe. These phenomena are the corner stones of our present knowledge about the quantum nature of space-time, and it is of crucial importance to understand deeply their features and consequences in the quest for a quantum theory of gravity. Unfortunately, these features are still poorly understood, and are experimentally out of reach in astrophysics. This project will bring together an experienced researcher with expertise in Hawking radiation and black hole physics, with a world leader physicist in artificial space-times in fluid flows to tackle these questions in the innovative approach of analog gravity. Unlike in astrophysics, artificial black holes can be experimentally realized using fluids, showing both their classical and quantum properties. Because these fluids are well understood, both experimentally and theoretically, many conceptual questions can be explicitly addressed in such systems. By working in a world-leading group in the field at the University of Nottingham, the local expertise and mine will be the perfect match to tackle these questions.
