A Bose-Einstein condensate is an exotic state of matter which can occur e.g. when a gas of atoms is cooled to extremely low temperatures. The phenomenon was predicted in 1925 by Satyendra N. Bose and Albert Einstein and observed for the first time in 1995.  Bose-Einstein condensates provide a unique window into the nature of quantum mechanics and are therefore of great interest to physicists. However, their properties are still not fully understood.

During his PhD research, Mikkel Berg Christensen studied previously unobserved properties of Bose-Einstein condensates in a laboratory of the Ultracold Quantum Gases Group. His research led to the first experimental characterisation of the highly debated statistical property called the atom-number fluctuations in the Bose-Einstein condensate. These findings contribute to the frontier of our knowledge of many-body quantum phenomena.

The PhD study was completed at the Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.
