1 Graduate Study in Physics and Astronomy at Rice University

2 Astronomy and Astrophysics Dufour, Hartigan, Johns-Krull, Oberlack Observational astrophysicists at Rice use infrared, optical and ultraviolet instruments on ground-based and space telescopes to study young stars and their collimated supersonic jets, the physics of emission nebulae, and the properties of starburst galaxies.

3 Astronomy and Astrophysics Baring, Fossati, Liang, I. Smith Members of the High-Energy Astrophysics group are involved in theoretical models and space-based experiments relating to compact objects, including gamma ray bursters, pulsars, and active galactic nuclei.

4 Space Physics Chan, Hill, Levy, Reiff, Toffoletto, Wolf Rice s space physicists investigate how the solar wind affects magnetized plasmas around the Earth during solar storms. Rice scientists are also analyzing the first spacecraft images of the Earth s magnetosphere. Satellite Image of the Earth s Plasmasphere (C. J. Pollock and J.-M. Jahn, SW Research Institute) Auroral Image (L. Frank Univ. of Iowa)

5 Space Physics Cloutier, Hill, Wolf Several members of the Space Physics group study magnetospheres and ionospheres around other planets, such as Venus, Mars, Jupiter and Saturn. A visible manifestation of mass loading (in ultraviolet light) is Jupiter s aurora (Note the magnetic footprint of Io.) The Io plasma torus is centrifugally unstable (like an inside-out Rayleigh- Taylor instability). [HST Image courtesy NASA & J. Clarke]

6 Atomic, Molecular and Optical Physics Dunning, Hulet, Killian, Lindsay, K. Smith The department has a diverse and active program in atomic, molecular, and optical physics. Research areas include ultracold trapped atoms and Bose- Einstein condensation. The figure shows a schematic diagram of the magnetic trap used to produce Bose-Einstein condensation of lithium atoms. The two lower figures are actual images of the trapped atoms. The cenral peak in the rightmost image is the Bose-Einstein condensate.

8 Nuclear and Particle Physics Bonner, Corcoran, Duck, Llope, Miettinen, Padley, Platner, Roberts, Stevenson, Yepes The High Energy and Nuclear Physics groups work closely together in a wide range of experiments. Equipment is built in Bonner lab and is sent to accelerator laboratories around the US and the World. The STAR (Solenoidal Tracker At RHIC) detector is used to study matter at extreme conditions produced in Nuclei Nuclei interactions. Rice has made important contributions in hardware and software.

9 Nuclear and Particle Physics Bonner, Corcoran, Duck, Llope, Miettinen, Padley, Platner, Roberts, Stevenson, Yepes The D0 experiment at Fermilab was one of the detectors that simultaneously discovered the top quark. Several members of the group have been involved in major upgrade to the detector. When it comes online, the Large Hadron Collider accelerator will be the world s highest energy facility. Several members of the group are helping to build triggering components of the detector.

10 Surface and Condensed Matter Physics Dunning, Hannon, Natelson, Nordlander, Rau, Rimberg, Si The Surface and Condensed Matter Physics group covers diverse areas including strongly correlated electrons, mesoscopic physics, magnetism, superconductivity, and surface physics.

11 Surface and Condensed Matter Physics Dunning, Hannon, Natelson, Nordlander, Rau, Rimberg, Si The Theoretical group is actively involved in studying many-body effects in solids, molecules, and atoms. The techniques use new types of algorithms that can be executed efficiently on computers with parallel architecture. Fermi surface of Vandium Oxide

13 Biophysics Huang The Biophysics group works on a new type of peptide antibiotics that act on cell membranes rather than proteins. The group has invented new ways of studying supramolecular structures formed by peptides in membranes using optical, X-ray and neutron techniques. Examples of neutron diffraction patterns

14 Biophysics Huang By using the techniques developed at Rice, the Biophysics group has been able to detect two types of pores formed by antimicrobial peptides. Barrel-stave model (alamethicin) Toroidal (wormhole) model (magainin)

15 Rice Campus Rice University is situated three miles from downtown Houston, nestled amidst a beautiful residential neighborhood, art museums, a world famous medical center, a city park and the Houston city zoo.

16 City of Houston A multifaceted international city, Houston is the fourth largest city in the U.S. and home to a diverse blend of ethnic groups and cultures. It s a center for the visual and performing arts, and international business hub, and home to the U.S. space program.
