Background and Research Interests
Magnus Lipp’s research interests focus on the behavior of materials under extreme conditions of pressure and temperature which might result in their transformation to new crystallographic phases or into whole new forms of matter with outstanding properties or cause them to disintegrate into their elemental constituents. One central theme concerns the possibility of storing/releasing energy in these new substances, energy that was expended in generating the transformation resulting in meta-stable, possibly energetic materials. The dramatic changes in their properties can be probed using light of any energy, for examples, Raman, luminescence, or non-linear spectroscopy such as CARS, as well as x-ray diffraction and spectroscopy.
Magnus received a MS in general physics from the Technical University of Munich, Germany, in 1986. He obtained his PhD from the University of Delaware in 1992, where he investigated multi-photon excitations of ionic crystals under pressure (advisor William B. Daniels). He joined LLNL as a staff member in 2000.
