Experimental Sciences & Mathematics

Maciej Lewenstein (Warsaw 1955) joined the Centre for Theoretical Physics of the Polish Academy of Sciences in Warsaw in 1980, did Ph.D. in Essen in 1983 with Fritz Haake and habilitated in 1986 in Warsaw. Postdocs at Universität Essen and at Harvard University with Roy J. Glauber (Nobel 2005), a faculty member of CEA in Saclay (1995-1998), and of the Leibniz University Hannover (1998-2005). In 2005 he moved to Catalonia as ICREA Research Professor to lead the quantum optics theory at the Institut de Ciències Fotòniques in Castelldefels. His interests include quantum optics, quantum physics, quantum information, many-body theory, attosecond science, and statistical physics. His other passion is jazz and avant-garde music - he is an acclaimed jazz writer and critic. At ICFO Maciej Lewenstein leads a 25 people team working on the mentioned subjects.


Research interests

Maciej Lewenstein is a theoretical physicist per se. His research interests are extremely diverse. He works on and contributes successfully to different branches of physics and other sciences. On one side he deals with purely mathematical questions related to foundations of physics, such as the nature of correlations in quantum systems. On the other extreme, Lewenstein has worked on models of human cognition and human voting behavior. Recently his interests mainly focus on quantum many body physics, quantum information theory, quantum optics, atomic physics, atto-nanophysics, quantum simulators, quantum open systems, statistical physics, Brownian motion theory and its applications to quantum physics, nano- and bio-photonics, applications of theoretical quantum chemistry to quantum many body physics, or machine learning for theoretical physics. In his research he uses extensively methods of the contemporary theoretical physics. At ICFO Maciej Lewenstein leads a 25 people team working on the mentioned subjects.
