Mid-Term Report Summary - SELFCOMPLETION (UV-Completion through Bose-Einstein Condensation: A Quantum Model of Black Holes)

The nature is intrinsically quantum. Nevertheless, in many instances the nature is described in the language of classical physics. For example, gravitational fields produced by macroscopic objects, such as, stars, galaxies or black holes, are described by the solutions of Einstein's gravitational equations, which are classical. The same applies to many objects in quantum field theory, such as, the solitons (non-linear waves) and other non-perturbative objects.

One of the main focuses of the project was to understand the underlying quantum description of these objects. This is extremely important both for understanding the quantum effects for seemingly-classical situations, as well as, for understanding the role of the classical objects in high energy quantum processes.

For instance, it is well accepted that black holes are formed in very high energy collisions of quantum particles, but it has never been understood previously how the transition from a two-particle quantum state to a macroscopic size classical black hole takes place.

The quantum portrait of black hole in form of multi-particle state, developed by the authors of the project, allowed - for the first time - to understand what is the correct quantum picture of the black hole formation in particle collisions. It turns out that this is represented by a transition from a two energetic quanta to many soft ones. The study of this process reveals a lot of interesting connections and new result.

It opened up a completely new avenues for the exploration of other classical object in form of multi-particle quantum states, including the universe itself. The cosmological spaces have always been treated classically and it was assumed that this is a good approximation to physical reality. The results of the project show that quantum effects can be extremely important on large enough time scales and dramatically change existing views on the fate of the cosmological spaces.
