Specialised Seminar: "From integer partition to Bose-Einstein condensate and its fluctuation" by Krzysztof Pawłowski (CFT, PAS, PL)
Join us for a specialised QUBITS Seminar, where Professor Krzysztof Pawłowski (Center for Theoretical Physics, Polish Academy of Sciences) will explore how a classic problem in number theory connects to ultracold gases, introducing Bose–Einstein condensation, atom-number fluctuations, and their implications for quantum technologies.

About the talk
The seemingly simple mathematical problem of partitioning a natural number into its summands remained unsolved until the 20th-century work of Hardy and Ramanujan. This problem is now fundamentally linked to the observed properties of ultra-cold gases.
This presentation will explain that connection, introduce the phenomenon of Bose- Einstein condensation, and discuss the fluctuations in the number of atoms that constitute it. The talk will conclude with a brief overview of matter-wave applications in quantum technologies and the potential impact of these fluctuations on such systems.
About the speaker
Professor Krzysztof Pawłowski is a theoretical physicist at the Center for Theoretical Physics of the Polish Academy of Sciences (CFT, PAS). His research is in ultracold gases, with a focus on quantum dipolar droplets, statistics of Bose–Einstein condensates, and entangled states in Bose–Einstein condensates.
He received his PhD degree in Warsaw in 2012 and has held postdoctoral positions in Stuttgart and at Laboratoire Kastler Brossel in Paris. He became an Associate Professor in 2015 and a CFT Professor in 2019.
