Laudatio

For his original and outstanding contributions to dynamics
of loosely bound nuclei and resonances
in Bose Einstein condensates

Prof. Dr. Mahir S. Hussein

has been awarded the Martin-Gutzwiller-Fellowship 2007/2008
of the Max Planck Institute for the Physics of Complex Systems.

Mahir S. Hussein is a world wide authority in theoretical nuclear physics and has made important contributions to ultracold atomic physics.

In the course of his scientific career, starting with a PhD from MIT in Cambridge, he has developed an unusual broad interest in and knowledge of theoretical physics documented by remarkable contributions to quantum chaos, laser driven charged particle acceleration, fundamental scattering theory and threshold physics.

Among his wide spread research interests, two fields stand out where he made his most important and recognized contributions. The first is the theory and dynamics of exotic nuclei, more specifically their break-up and fusion properties in loosely bound systems, as demonstrated, e.g., in a Physical Review Letter from 1992 on "Near barrier fusion on Li_11 with heavy spherical and deformed targets" and recently summarized in a review article for Physics Report in 2006.

His second well recognized line of research is the dynamics of Bose Einstein condensates. He entered this field in the end of the 1990s. Together with
E. Timmermanns he pointed out in 1999 peculiar properties of condensates related to the transition from an atomic to a molecular condensate, a pioneering paper in the research on molecular condensates. In the same year Mahir Hussein published together with colleagues at the Institute of Theoretical Atomic and Molecular Physics in Cambridge an article on "Feshbach Resonances in Bose Einstein Condensates" which has become the standard reference in the field.

The topic Feshbach resonances closes a circle back to Mahir Hussein's scientific origin in nuclear physics. His research achievements are an impressive proof how successful and gratifying cross fertilization between different fields can be if advanced by a scientist with the rare intellectual strength and horizon to do so.
