The 2009 Christmas party showcased the true spirit of the Department of Physics and Astronomy. Each year, faculty, staff, and students join for an hour of music and refreshments, but 2009 brought us something new:
Neutrino Events Detected for First Time in T2K Experiment
November 24, 2009
Physicists from the T2K neutrino collaboration announced today that they have detected the first events generated by the neutrino beam at the J-PARC accelerator laboratory in Tokai, Japan. This detection marks the beginning of the operational phase of the T2K experiment, a ~500 physicist, 12-nation collaboration to measure new properties of the ghostly neutrino.
UR Physicists Determine Mass Difference between Top and Antitop Quarks
October 6, 2009
A team of physicists in the Department has performed the first direct measurement of the mass difference between a quark and its antimatter partner (antiquark). Quarks are the fundamental particles that make up protons and neutrons, the stuff that regular matter is made of. Before antimatter was discovered, Paul Dirac introduced it as a requirement of the laws of quantum mechanics and Einstein's relativity. Scientists have been producing and studying antimatter such as antiprotons, antineutrons and antielectrons (or positrons) for many decades. All antimatter particles are supposed to have the same masses and lifetimes as their matter partners, but with opposite electric charges. Indeed, the masses and lifetimes of antimatter particles have been measured and found to be identical to their normal matter counterparts. Even more complicated objects such as pions, kaons, light nuclei, and hydrogen atoms appear to agree with this matter and antimatter "symmetry."

In consultation with the Chair of Undergraduate Awards Committee, Gregory's instructors in PHY 141, 142, 143, and 237 selected him for the honor, which includes a copy of The Feynman Lectures in Physics volumes, a paid membership in the AAPT, and a subscription to Physics Today.
Emil Wolf Proposes Method to Determine the Phases of X-ray Beams Diffracted by Crystals
September 23, 2009
In a recent Physical Review Letters paper, Wilson Professor of Optical Physics and Theoretical Physics Emil Wolf introduces a technique that overcomes the long-standing difficulties relating to measuring phases of diffracted x-ray beams in structure determination of crystals. The current methods incorrectly assume that x-rays are monochromatic, and as Wolf points out in a recent physicsworld.com article, this type of beam is not found in nature and cannot be created in the lab. He proposes that physicists use spatially coherent x-rays that can be produced in the lab and that they measure beam correlation functions to obtain missing structural data.
Professor Adam Frank's Science Writing Makes National Collection
July 7, 2009
Adam Frank, Professor of Astrophysics at the University of Rochester, is a computational scientist whose research group develops state of the art supercomputer codes to study star formation and stellar death. He is also a popular science writer who has written numerous articles for national magazines as well as a recent book on Science and Religion. Now one of Frank's magazine articles has garnered the national honor of being included in "The Best American Science and Nature Writing 2009" published by Houghton Mifflin. Each year the "Best of" editors read hundreds of articles on science and nature from sources ranging from the New Yorker to Natural History. Of those articles only a handful are selected for the book.

NASA Spitzer Space Telescope Moves from Cryogenic to "Warm" Mission
May 29, 2009
The NASA Spitzer Space Telescope's cryogenic mission is over. At approximately 2:30 PM EDT on Friday, 15 May 2009, precisely as expected, the last of the facility's liquid-helium coolant evaporated. The telescope and instruments began quickly to warm up from the temperature, 1.5 degrees above absolute zero, at which they have been kept for the 5.7-year duration of the mission. The temperature is expected to level off at about 30 degrees above absolute zero, at which the observatory's Infrared Spectrograph and Multiband Imaging Photometer, and half of the detector arrays in the Infrared Array Camera, can no longer function.

Continue ReadingWeak value measurements by a strong duo
April 23, 2009
Assistant Professor Andrew Jordan and Associate Professor John Howell teamed up this past year with collaborators to make three strong advances related to weak value measurements and slow light. First, they discovered that gravity can push slow light down by about 1 Angstrom in the lab. Second, they demonstrated an optical pi cross-phase modulation jump. And third, they were able to measure extremely small (560-femtoradian) shifts of an optical beam. Much of this work merged Jordan's theoretical research with weak value measurements and Howell's experimental research with slow light and optical systems.
