Johann Rafelski

Johann Rafelski (born 19 May 1950) is a German-American theoretical physicist. He is a professor of physics at the University of Arizona in Tucson, guest scientist at CERN (Geneva), and has been LMU-Excellent Guest Professor at the Ludwig Maximilian University of Munich in Germany.

Rafelski's current research interests center around investigation of the vacuum structure of QCD and QED in the presence of strong fields; study of the QCD vacuum structure and deconfinement with strange particle production in deconfined quark–gluon plasma formed in relativistic heavy ion collisions; the formation of matter out of quark–gluon plasma in the hadronization process, also in the early Universe; considering antimatter formation and annihilation. He has also contributed to the physics of table top muon-catalyzed fusion and the ascent of ultrashort laser light pulses as a new tool in this domain of physics. He contributed to understanding of neural nets and artificial intelligence showing importance of neural plasticity and "sleep". Provided by Wikipedia
