Matter Under
Extreme Conditions
Research on
matter under extreme conditions include high-pressure physics, shock
compression, and physical acoustics. Students are exposed to interdisciplinary
research that emphasizes a fundamental understanding of materials
subjected to static and dynamic pressures.
Dr.
Zbigniew Dreger uses diamond-anvil cells to apply large static
pressures to organic crystals. He uses optical techniques
such as Raman spectroscopy and impulsive stimulated thermal
scattering to investigate changes in solids caused by extreme
stress.

Dr.
Yogendra Gupta is the Director of the Institute for Shock
Physics, a multidisciplinary research organization with an
emphasis on shock wave and high pressure research on materials.
State-of-the-art computational and experimental facilities
are used to investigate phenomena over a significant range
of length and time scales. |

Dr.
Phil Marston
performs research in physical acousitcs and optics. One topic
is the radiation pressure of high-amplitude sound and its
applications to bubble and droplet dynamics and to the dynamics
of of fluids in low gravity. The image at right was taken
9 April, 2003, by cosmonaut Nikolas Budarin aboard the ISS
in near-zero gravity conditions. It shows an air bubble inside
a water droplet on a plant in the "space garden." |

Dr.
Matt McCluskey investigates semiconductors under large
pressures. His group uses infrared spectroscopy combined with
diamond-anvil cells to probe defects in semiconductors, and
studies the optical changes of semiconductors under shock
compression. |
