Stephen E Nagler

Corporate Research Fellow

Stephen E. Nagler is a Corporate Research Fellow of Oak Ridge National Laboratory, and is also affiliated with the University of Tennessee, Knoxville Department of Materials Science and Engineering.  His primary research interest is in condensed matter physics, especially quantum materials.  He makes extensive use of neutron scattering techniques, emphasizing inelastic scattering to investigate the dynamics of materials, and also has long experience with high resolution and time resolved x-ray scattering.  Some examples of the research topics on which he has published include fractional excitations in  one-dimensional quantum magnets, phase transitions in two dimensions, non-equilibrium behavior of alloys and polymers, quantum criticality, novel superconductors, frustrated magnetism and quantum spin liquids. Dr. Nagler was involved in the conceptual development of several instruments at ORNL’s Spallation Neutron Source and was the Principal Investigator for the SEQUOIA chopper spectrometer.  Previous to that he was a founding member of the MR-CAT group that developed instrumentation at the Advanced Photon Source.  

Dr. Nagler received his Ph.D. in Physics from the University of Toronto in 1982 and moved that year to the IBM Thomas J. Watson Research Center in Yorktown Heights, NY. In 1984 he joined the faculty of the University of Florida, where he received a National Science Foundation Presidential Young Investigator award in 1986. Dr. Nagler served as a Professor of Physics at Florida until moving to ORNL in 1995.   At ORNL he was a group leader and later acting director of the HFIR Center for Neutron Scattering prior to its merger into the Neutron Sciences Directorate, and also served as the director of the former Quantum Condensed Matter Division. Dr. Nagler has been a Visiting Professor at the Clarendon Laboratory, University of Oxford, UK, the Weizmann Institute of Science, Israel, and Risø Laboratory in Denmark.  He is a Fellow of the American Physical Society, the American Association for the Advancement of Science and the Neutron Scattering Society of America.  Among other activities he has served as a member of the editorial board of the journal Physical Review Letters and as a member of the executive committee of the Division of Condensed Matter Physics of the American Physical Society.
