Kay Malmstrom Lecture in Physics 2012 Lecture Dr. Wolfgang KetterleNobel Laureate and John D. MacArthur Professor of Physics, Massachusetts Institute of Technology Lecture Title: "When Freezing Cold is Not Cold Enough: New Forms of Matter Close to Absolute Zero Temperature"Wolfgang Ketterle has been the John D. MacArthur professor of physics at MIT since 1998. He leads a research group exploring the properties of ultracold gases. His research is in the field of atomic physics and laser spectroscopy and includes laser cooling and trapping, atom optics and atom interferometry, and studies of Bose-Einstein condensation and Fermi degeneracy. His observation of Bose-Einstein condensation in a gas in 1995 and the first realization of an atom laser in 1997 were recognized with the Nobel Prize in Physics in 2001 (together with E.A. Cornell and C.E. Wieman).Dr. Ketterle received a diploma (equivalent to master’s degree) from the Technical University of Munich (1982) and a Ph.D. in physics from the University of Munich (1986). He did postdoctoral work at the Max-Planck Institute for Quantum Optics in Garching and at the University of Heidelberg in molecular spectroscopy and combustion diagnostics. In 1990, he came to MIT as a postdoc and joined the physics faculty in 1993.His many honors include the Rabi Prize of the American Physical Society (1997), the Fritz London Prize in Low Temperature Physics (1999), the Benjamin Franklin Medal in Physics (2000), the Knight Commander’s Cross (Badge and Star) of the Order of Merit of the Federal Republic of Germany (2002), the MIT Killian Award (2004), a Humboldt research award (2009) and memberships in several Academies of Sciences. He holds Honorary Degrees from Gustavus Adolphus College, St. Peter (2005), the University of Connecticut (2007), and Ohio State University (2007).
