Maciej Lewenstein graduated from Warsaw University and completed his Ph.D. at the University of Essen. He was a faculty member of the Centre for Theoretical Physics of the Polish Academy of Sciences until 1995, and then joined the Service des Photons, Atomes et Molécules of the Commissariat à l’Énergie Atomique (CEA) in France. In 1998 he moved to the University of Hanover, and since 2005 he has been the head of the quantum optics theory group at the Institute of Photonic Sciences (ICFO) in Castelldefels, Spain, and a Professor at the Catalan Institution for Research and Advanced Studies (ICREA). His interests include the quantum physics of cold atoms and other many-body systems, quantum information theory and mathematical physics and attosecond physics. He is an APS Fellow and a recipient of both the Humboldt Research Award and the European Research Council Advanced Grant.
A Bose-Einstein condensate (BEC) can dramatically collapse and explode when the interactions between the atoms are sufficiently strong and attractive. Now, scientists have imaged the anisotropic, clover-leaf shape of such a collapsing gas when the attractive atomic interactions are strongly dipolar.
