Dowling has been elected a Fellow of the American Physical Society (APS) by the Division of Atomic, Molecular, and Optical Physics (DAMOP) in recognition of his "major contributions to quantum optics as it pertains to the development of the theory of atomic emission rates and nonlinear switching in photonic crystals, as well as seminal contributions to quantum metrology and imaging, especially the invention of quantu lithography."

  • RESEARCH NEWS! -

    The ATIC Collaboration has discovered an excess of electrons in the cosmic rays at 300-800 GeV. This may be the first observation of a nearby source of particle acceleration from an as yet unidentified astrophysical object or it could be a signature of the annihilation of a Kaluza-Klein dark matter particle of mass about 620 GeV. The finding is reported in "An Excess of Cosmic Ray Electrons at Energies of 300-800 GeV" by John Wefel, Greg Guzik, Joachim Isbert et al. in Nature 456, 362 (2008) and is featured in Nature News & Views p. 329 as well as being the subject of a NASA press release and in The Advocate. ATIC was largely constructed at LSU and the excess in the spectrum was discovered in data collected during ATIC's first two Antarctic balloon flights. More information about the ATIC experiment can be found here.

  • Research News! - D. Uskov and A. R. P. Rau: Geometric phases and Bloch-sphere constructions for SU(N) groups with a complete description of the SU(4) group", Phys. Rev. A 78, 022331 (2008), provides a geometrical view of two-spin quantum systems. The quantum system of a pair of spins (qubits) lies at the heart of quantum computing, quantum cryptography and related areas of current research. This paper develops a geometrical picture for the time evolution of such systems that closely parallels a similar picture, called the Bloch sphere, which has been very influential over the decades for the quantum mechanics of a single spin in magnetic fields. This latter picture of a unit vector rotating on a sphere provides both basic insight into magnetic resonance and guides its applications in chemistry, biology and medical magnetic resonance imaging. Extension to two (or more) spins provides analogous geometrical objects, albeit of higher dimension, including spheres of larger dimension. The quantum evolution is mapped into that of real vectors rotating on such geometrical manifolds.

  • RESEARCH NEWS ! - By replacing a few percent of iron atoms with manganese in the semiconductor ferrosilicon (FeSi), John DiTusa, former student Ncholu Manyala, and colleagues have demonstrated a possible method for systematically inducing non-Landau Fermi liquid behavior in doped semiconductors. ("Doping a semiconductor to create an unconventional metal", Nature 454, 976, 2008). See also the News and Views article "Materials Science: A metal left spinning", Nature 454, 951 (2008). The effect is apparently due to too few mobile electrons to compensate for the spins of unpaired electrons on the impurity atoms. The behavior can be turned on or off by applying a magnetic field at low temperature. More information.

  • Ph.D. student, Jennifer Andrews has been awarded a NASA Graduate Student Researchers Program (GSRP) Fellowship for her thesis research on "A Multi-Wavelength Study of Dust Production in Type II Supernovae."

  • RESEARCH NEWS ! - Three papers by the theoretical and experimental gravity group have been highlighted by the editorial board of the journal Classical and Quantum Gravity this year: [1] In "Rotating collapse of stellar iron cores in general relativity" (Class. Quantum Grav. 24, S139 2007), B. Zink, E. Schnetter, and colleagues present the results of simulations of the collapse of rotating stellar iron cores, focusing on the gravitational wave emission during the collapse, core bounce, and post-bounce phases. [2] In "Late-time tails in the Kerr spacetime" (Class. Quantum Grav. 25, 072001, 2008), Jorge Pullin and colleagues describe the decay with time of perturbation fields outside a black hole. [3] In "Search for gravitational-wave bursts in LIGO data from the fourth science run" (Class. Quantum Grav. 24, 5343, 2007), the LIGO Science Collaboration (including R. Amin, L. Blackburn, J. Giaime, G. Gonzalez, C. Hanna, W. Johnson, A. Rodriguez, J. Slutsky, and M. Sung at LSU) describe the results of the fourth science run with the LIGO and GEO 600 gravitational wave detectors. With significantly lower noise and greater sensitivity than previous runs, no positive signals from supernova or binary black hole merger events were detected. The theoretical gravity group has made the Classical and Quantum Gravity highlights list every year since the groupt started at LSU in 2001!

  • RESEARCH NEWS ! - The binary pulsar system PSR J0737-3039A/B consists of two closely spaced neutron stars in an edge-on configuration such that one pulsar eclipses the other once in every 2.45 hr orbit. The spin of one compact rotating star couples with the orbital angular momentum and the spin of the other, analogous to spin-orbit and spin-spin coupling in an atomic system, providing a test of general relativity in the strong-field regime. The relativistic spin precession of pulsar B has now been measured to be about 4.80/year, R. Breton et al., Science 321, 104, 2008 , in agreement with the prediction of 5.10/yr made by B. Barker and R.F. O'Connell, Phys. Rev. D12, 329 (1975), within an observational uncertainty of 13%. See also R.F. O'Connell , http://arxiv.org/abs/0804.3806 (2008) which reviews both strong and weak-field tests. The terminology spin-orbit and spin-spin in the gravitational context was introduced by R.F. O'Connell, in Experimental Gravitation:Proceedings of Course 56 of the International School of Physics "Enrico Fermi," B. Bertotti, Ed. (Academic Press, New York, 1974), p. 496.

  • RESEARCH NEWS ! - The Auger Collaboration (including Jim Matthews, Alexei Dorofeev, Javier Gonzalez at LSU, and Megan McEwan, Roger McNeil, and Rishi Meyhanden formerly in the department) has published evidence for a cutoff at the high end of the cosmic ray spectrum. Auger previously showed that the arrival directions of cosmic rays at energies above 6 x 1019 eV were correlated with the directions of Active Galactic Nuclei -- i.e., that the highest energy cosmic rays are extragalactic in origin. Now, at the same energy, Auger has demonstrated the presence of the predicted GZK cutoff due to the interaction of extragalactic protons with the cosmic microwave background. The scientific article appears in Physical Review Letters 101, 061101 (2008). A commentary by Mike Cherry appears on the APS Physics Viewpoint web site.

  • RESEARCH NEWS ! - LSU and Florida State University (FSU) are collaborating to develop the Array for Nuclear Astrophysics Studies with Exotic Nuclei (ANASEN). ANASEN combines three different types of detectors to achieve an efficient and selective instrument for studies of nuclear reactions induced by low intensity beams of exotic nuclei. Solid-state and gaseous detector technologies are being developed with state-of-the-art electronics systems to provide accurate measurements of the energies and trajectories of charged ions over a large angular range. Students at LSU and FSU will develop and test detector elements that will be combined into a completed array and used in experiments with beams of exotic nuclei at the Fox Superconducting Accelerator Laboratory at FSU. ANASEN will allow new direct measurements of nuclear reaction cross sections that are important for understanding stellar explosions like X-ray bursts and the structure of short-lived nuclei. ANASEN will also be a portable instrument that will be moved to the National Superconducting Cyclotron Laboratory at Michigan State University and potentially to other laboratories. LSU and FSU students will have a unique opportunity to conduct leading research in nuclear physics and nuclear astrophysics with ANASEN at major national accelerator facilities. Students will also gain invaluable hands-on experience in forefront instrumentation and techniques that are important for various fields from health care to national security. ANASEN is funded by the by the National Science Foundation's Major Research Instrumentation Program and by LSU and FSU, and led at LSU by Jeff Blackmon.

  • RESEARCH NEWS ! - The LIGO collaboration (including the LSU group led by Profs. Joe Giaime, Gabriela Gonzalez, Bill Hamilton, and Warren Johnson), has presented upper limits on gravitational wave emission from the Crab pulsar, giving an upper limit on gravitational wave emission that beats indirect limits inferred from the spin-down and braking index of the pulsar and the energetics of the nebula. The scientific paper can be found here. A popular writeup can be found here.

  • RESEARCH NEWS ! - Titanium dioxide (TiO2) has a number of uses in catalysis, photochemistry, and sensing that are linked to the reducibility of the oxide. Usually, bridging oxygen (Obr) vacancies are assumed to cause the Ti 3d defect state in the TiO2 band gap. Phil Sprunger and colleagues from the Interdisciplinary Nanoscience Center, Department of Physics and Astronomy, and Institute for Storage Ring Facilities at the University of Aarhus in Denmark propose that Ti interstitials in the near-surface region may be largely responsible for the defect state in the band gap. Based on data from high-resolution scanning tunneling microscopy and photoelectron spectroscopy measurements, they argue that these donor-specific sites play a key role in and may dictate the ensuing surface chemistry. Density functional theory calculations support the experimental observations. The scientific paper was published in Science 320, 1755 (2008).

Science
 RESEARCH NEWS ! - The Auger experiment has announced the first correlation of ultra-high energy (1020 eV) cosmic ray arrival directions with extragalactic sources. Based on a sample of data taken between 2004 and 2007, Auger sees evidence for their highest energy events coming from the directions of nearby active galactic nuclei. The scientific article appears in Science.
ATIC
 RESEARCH NEWS ! - The ATIC cosmic ray balloon experiment is featured on LSU's home page as part of LSU's Antarctic research program. ATIC is preparing for its third flight to measure the composition and energy spectrum of high energy cosmic ray nuclei and electrons. Details and the latest news regarding the current flight campaign can be found here.
Gemini
 RESEARCH NEWS ! - At the 209th meeting of the American Astronomical Society in Seattle, Washington, astronomers announced findings of unusually high levels of the oxygen isotope 18O in two extremely rare types of stars. This breakthrough has led astronomers to believe that the origin of these odd stars could be the merging of white dwarf stars, the burnt-out remnants of normal stars like the Sun. Read the entire article in our Fall 2007 departmental newsletter. For more information, The Gemini Observatory website press release can be found here. The Gemini press release recorded more hits (more than 50,000) in the first three months after its release than any previous Gemini press release.
Auger Ezra
 RESEARCH NEWS ! - "The Pierre Auger Observatory: Measuring the Highest Energy Cosmic Rays" - In July 2007, the initial Auger results were presented at the 30th International Cosmic Ray Conference in Mexico. The data indicated a clear cutoff in the spectrum near 1020 eV, a result known as the "GZK cutoff" and expected due to interactions of high energy cosmic ray protons with the cosmic microwave background. The Auger Collaboration consists of over 200 scientists from more than 20 countries. The group participating from LSU is led by Prof. James Matthews and includes Prof. Roger McNeil, postdocs Alexei Dorofeev and Javier Gonzalez, graduate student Megan McEwen, and undergraduate students Rachel Mannino and Brittan Farmers. Prof. Matthews has been a part of the project since it was first conceived in 1992. More information about Auger can be found by visiting Nature.com, Science Magazine, or the Auger Observatory website. Read the entire article in our Fall 2007 departmental newsletter.

  • RESEARCH NEWS ! - "The Relativistic Turducken Approach to Stuffing a Black Hole" - Erik Schnetter, Manuel Tiglio, and Peter Diener from LSU's Physics and Astronomy Department and the Center for Computation and Technology, working together with colleagues from the Universidad Michoacana de San Nicolas de Hidalgo in Mexico, North Carolina State University, the University of Southampton in Britain, and the Albert Einstein Institute in Germany, have shown how to stuff a black hole. The result is that their "turducken" approach to stuffing a back hole may lead to useful methods of simulating the behavior of real black holes irrespective of many of the unobservable details of how the interior stuffing is arranged. A preprint of the paper can be found on the web. More information can be found in the article in our Fall 2007 departmental newsletter.
  • RESEARCH NEWS ! - "Medical Physics is a fundamental science concerned with improving people's lives," said Dr. Polad Shikhaliev, who joined the LSU faculty in January, 2007 as an Assistant Professor in its joint Medical Physics Program with Mary Bird Perkins Cancer Center. "Medical Physics has a direct impact on people's health, helping cure breast cancer. As a medical physicist, I conduct research with detector technology to find cancer earlier". Dr. Shikhaliev's current research is focused on developing a new breast CT system that will allow detecting breast cancer at its very early stages. Breast CT, as proposed by Dr. Shikhaliev, should be able to detect breast lesions as small as 2-3 mm, compared to 10mm, which is often the case in current mammography x-rays. He also expects his research to acquire the CT scan with less radiation dose to the breast than current low-risk mammography techniques and with no pain or discomfort.

  • Prof. Bradley Schaefer has just won a share of the 2007 Gruber Cosmology Prize as a particiapant in the discovery that the expansion of the Universe is accelerating, not decelerating as expected. By measuring the brightnesses of a large number of very distant supernovae, two competing teams -- the Supernova Cosmology Project and the High-z Supernova Search team -- simultaneously determined that the expansion of our Universe is accelerating, a surprising result since confirmed by several independent methods. The conclusion is that approximately 70% of the mass/energy of our Universe is due to a previously unknown 'force' now called 'Dark Energy'. The $500,000 prize money will be shared amongst the co-authors of the original papers, with the award ceremony being held on 7 September 2007 at Trinity College in Cambridge.
