What we observe is not nature in itself but nature exposed to our method of questioning.

Hello, my name is Aleksas Mazeliauskas. I am a theoretical physicist working on many-body phenomena emerging from interactions of a small number of particles in high-energy hadron collisions and ultracold quantum gases.
Since 2022 I have been leading an Emmy Noether Research Group at the Institute for Theoretical Physics at Heidelberg University. As of 2024, I am a project leader at the Collaborative Research Center ISOQUANT.
My group’s research focuses on the microscopic understanding of the emergent collective phenomena in systems of varying sizes and at varying energy scales. I am especially interested in the question of thermalisation and hydrodynamic behaviour in isolated quantum systems.
Check out my research projects, publications and profiles of my group members. See the news announcements for open positions and my blog for occasional posts about my life as a researcher.
