    04/15/15 - The American Physical Society, the world's largest physics society, will join Indiana University in providing a new path for underrepresented minorities to pursue a doctorate degree in physics.

    The College of Arts and Sciences' Department of Physics at IU Bloomington will receive nearly $180,000 over three years as a 2015-16 recipient of a site grant from the American Physical Society Bridge Program, which supports students who might otherwise not qualify for physics doctoral programs because they lack course requirements or lab experience. IU is one of only two new sites selected for the program across the country this year.

    The IU Graduate School and College of Arts and Sciences will provide additional support to extend the number of students accepted under the program from two to five students per year, and will fund the program for an additional two years beyond the award period.

    "Physics is a vocation that anyone can pursue and, historically, contributions in physics have come from all countries and all people," said Jon Urheim, professor in the Department of Physics, who will serve as director of the IU APS Bridge Program. "In this country, however, physics has lagged in terms of diversity, and we would like to be part of the effort to rectify the situation. Some of the discipline's greatest achievements result from the broadest possible range of perspectives and problem-solving. Increasing diversity not only benefits those who have a passion for physics but also the overall advancement of knowledge in the field."

    Underrepresented minorities comprise 35 percent of the college-age population but fewer than 20 percent of all bachelor's degree holders, according to the American Physical Society. They also comprise fewer than 10 percent of students with bachelor's degrees in physics and only about 5 percent of doctoral degrees awarded each year. The time between undergraduate and graduate school is where the largest number of underrepresented minorities decline to continue their pursuit of physics.

    "IU's selection as a site for this bridge program is an honor for the university, as well as the Department of Physics, and will surely help attract talented new students to IU and the field of physics from across the country," said James Wimbush, vice president for diversity, equity and multicultural affairs and dean of the University Graduate School. "We're eager to greet this new cohort of scholars when they join us next year."

    A total of 15 institutions applied for funding under the 2015-16 American Physical Society program grant, with only six invited to participate in the final selection process and only two receiving funding. The other successful recipient under this year's grant was the University of Central Florida. Additional APS Bridge Program sites, selected in previous years, are California State University Long Beach, Florida State University, The Ohio State University and University of South Florida.

    As a program site, IU is one of a select few institutions with access to top student applicants from across the country. The national bridge site program is highly competitive, with many talented students applying each year.

    "IU's selection as an APS Bridge Program site will deliver multiple benefits to the university and our students," said David Daleke, vice provost for graduate education and health sciences and associate dean of the University Graduate School. "The program will recruit highly motived students to our graduate physics program and will provide a support structure and mentorship to ensure their success in doctoral studies. We hope the program will not only help put IU at the top of the list nationwide among a talented and diverse pool of new applicants but will also contribute to the goal of increasing the number of underrepresented minority Ph.D. graduates in physics."

    The selected bridge program fellows will spend two years at IU in an individualized master's degree program pursuing additional coursework and research experiences to enhance their ability to compete in a doctoral physics program. Students enrolled in the program will receive a stipend of $20,000, partial tuition coverage and health benefits.

    Students accepted into the program will be able to select classes from the physics department's graduate and undergraduate curriculum, including many laboratory courses, potentially enabling a seamless transition to the IU doctoral program. Intensive mentoring of bridge program fellows will be a central element of the IU program. The department also plans to launch an enhanced version of its professional development program for graduate students enrolled through the bridge program.

    "Many of the support services being launched as part of the program will also benefit our existing students," Urheim said. "There is evidence that greater attention to mentoring leads to higher success rates for students pursuing doctorate degrees in physics."

    In addition to Urheim, Department of Physics members engaged in IU's successful application to the American Physical Society were Distinguished Professor Steven Gottlieb; assistant professors Lisa Kaufman and Babak Seradjeh; graduate student Fernanda Psihas; Rex Taylor, professor and chair of graduate admissions; and research scientist Garfield Warren.

    The first students accepted into the IU program will begin this fall.

    02/10/15 - It is a sad occasion for the entire Physics Department to announce the recent death (February 1, 2015) of Daniel W. Miller. Many of your will remember Dan fondly as an active member of the Physics Department, both as a careful teacher and as a researcher using two generations of cyclotrons at Indiana University. Dan also played a very significant role in IU Administration.

    Dan came to IU in 1951 and he remained an active member for nearly 40 years. In addition to teaching several generations of IU undergraduates, Dan's doctoral students carried out significant research projects using two generations of cyclotrons at IU and the Indiana University Cyclotron Facility (IUCF). When Dan was the acting chairman of the department, he coauthored (with input from several departments) a proposal to the National Science Foundation for an NSF Science Development Grant. This NSF grant had an extraordinary impact on the physical sciences program at Indiana University.

    Dan's research carried out on these two facilities have stood the test of time in their impact on the field of Nuclear Physics. In addition to serving as acting chair of the department, Dan also served as an associate dean of the College of Arts and Sciences and associate dean of Research and Advanced Studies. Dan was Chairman of the University Athletics Committee and served as faculty representative the Big Ten and the NCAA. Dan received a number of awards. He was perhaps most proud of his service on the Athletic Committee and especially of the Distinguished Service Award that he received from the President of Indiana University.

    We will especially miss Dan's wry smile, his great integrity, his collegiality as a member of our department and his extraordinary gift for organization.

    A memorial celebration service for the life of Daniel Weber Miller will be held on a date to be determined in the spring of 2015. Donations in Dan’s memory may be made to the IU Physics Department, the Bloomington WonderLab Science Discovery Museum, and the First Presbyterian Church of Bloomington. Online condolences may be given to the family at

    02/06/15 - IUB Professor of Physics Hal Evans has been appointed as “Phase-II Upgrade Technical Coordinator” for the United States contribution to the ATLAS experiment at CERN's Large Hadron Collider in Geneva Switzerland. He will be part of the group of five physicists leading the effort to develop the ATLAS Phase-II upgrade program in the U.S. The Phase-II upgrade of the ATLAS detector, scheduled to come online in 2025, will build on the recent discovery of the Higgs boson to search for new phenomena such as Supersymmetry and Dark Matter that will deepen our understanding of the fundamental structure of the universe. The U.S. part of the upgrade program, expected to require $250 million in funding, will involve more than 500 physicists, engineers, technicians, and students from nearly 50 U.S. universities and National Labs. Evans will concentrate on coordinating nation-wide efforts to develop the new technologies necessary to cope with the increasing intensity of proton-proton collisions produced by the Large Hadron Collider and will interface with the Department of Energy and the National Science Foundation to secure the funding necessary to do this work.

    IUB has a long history of involvement on the ATLAS experiment. Professor emeritus Harold Ogren led the group in the U.S. that built part of the existing ATLAS detector: the Transition Radiation Tracker. Sr. Research Scientist Fred Luehring, in collaboration with UITS, co-leads one of the five major ATLAS computing centers in North America: the Midwest Tier-2 center. The current IUB ATLAS group consists of Prof's Hal Evans, Sabine Lammers, and Rick Van Kooten; Research Scientists Fred Luehring and Daria Zieminska; postdoc Narei Lorenzo-Martinez; and graduate students KyungEon Choi, Aparajita Dattagupta, Alex Johnson, Rebecca Linck, and John Penwell.

    Statistics (from BNL Director's Review of US ATLAS Operations, Jan. 26-27, 2015) ATLAS: ~2,800 authors, 189 institutes, 38 countries, 381 publications US ATLAS: 550 authors (775 scientists and engineers), 45 institutes

    01/14/15 - Undergraduates Johnathon Lowery, Josh Foster, and Tom Dauer represented Indiana University Bloomington the in the 2014 University Physics Competition and were awarded a silver medal for their work on a problem titled "Circumbinary Planets”. Prof. Rick Van Kooten is the team’s advisor.

    From the Competition’s website: "The University Physics Competition is an international contest for undergraduate students, who worked in teams of up to three students at their home colleges and universities all over the world, and spent 48 hours during the weekend of November 14, 15, & 16, 2014, analyzing an applied scenario using the principles of physics, and writing a formal paper describing their work.”

    12/15/14 - IUB Physics faculty member Jorge José, and graduate student Di Wu have contributed to a study on the fine structure of movement patterns. Individuals move in unpredictable ways, with very short time fluctuations imperceptible to the naked eye. An IU-Rutgers collaboration has done a statistical modeling analysis of the kinematics of moving autistic individuals, at the millisecond time scale. The results led to defining quantitative predictive biomarkers about the severity of the condition as well as to filial links for more information, see

    11/19/14 - IUB Professor of Physics Mike Snow has won one of two awards for the 2014 NIST Precision Measurement Grant Competition. The award will support a project to perform absolute neutron flux measurements needed for precision measurement of the lifetime of the neutron. The scientific interest in precision measurements of the neutron lifetime is due to its direct influence on the amount of helium produced in the Big Bang. The Big Bang Theory (the real one, not the TV show) makes a precise prediction for the relative amounts of hydrogen and helium in the early universe before stars started to form. Work by many members of the IU astronomy department has also been devoted to this general topic. IUB Associate Professor of Physics Chen-Yu Liu is leading a different experimental effort to also measure the neutron lifetime with high precision. No faculty member from Indiana University has ever won this competition until this year. However it is interesting to note that one of the award winners of the competition when it was first started in 1970 was an IUB alumnus: James Faller, who was an IU undergraduate major of physics in the 1960s before going to Princeton for his PhD work. Faller later played a major role in the decision to put "corner cubes" on the Moon: decades later these cubes were used to make extremely precise measurements of the Earth-Moon distance good enough to conduct a powerful test Einstein's ideas of curved spacetime. Faller also conducted some of the most sensitive experiments to measure Newton's famous gravitational constant G (a number well-known to all physics students).

    09/03/13 - In search for dark matter components, IU physicists edge closer by watching radiation shifts

    Work is a collaboration with Northrop Grumman, University of Wisconsin


    Sept. 4, 2013

    BLOOMINGTON, Ind. -- Nuclear magnetic resonance -- that phenomenon where nuclei of certain atoms, when in a magnetic field, take in and give off measurable amounts of electromagnetic radiation -- is everywhere.

    Indiana University Health Proton Therapy Center uses a type of it to visualize nuclei of atoms inside the human body, and chemists like IU's David Giedroc use nuclear magnetic resonance to determine protein structure. Its radio frequency range of between 40 and 50 megahertz is akin to that of short wave amateur radio. Even water, when you zoom in on the single proton found in the nuclei of its two hydrogen atoms, produces a measureable nuclear magnetic resonance signal.

    Two isotopes of xenon gas were placed inside a 2-millimeter glass vapor cell and then polarized inside a magnetic field in a search for nuclear magnetic resonance frequency shifts. The test station is also used by Northrop Grumman in developing sub-atomic gyroscopes.

    Now, a team of physicists at IU Bloomington that has been hunting for nuclear magnetic resonance frequency shifts 100 billion times smaller as part of a search for new particles in nature that are very weakly coupled to matter, has never been closer to confirming whether the predicted particles do exist. Print-Quality Photo

    Led at IU by College of Arts and Sciences' Department of Physics professor W.M. Snow in collaboration with researchers at Northrop Grumman Corp. and the University of Wisconsin, the team this week announced a new set of nuclear magnetic resonance frequency shift measurements in two polarized isotopes of the noble gas xenon. The new results provide the highest level of sensitivity to date for the possible presence of exotic new particles with masses in the sub-electron volt range (less than the mass of a single neutron, proton or electron).

    These new predicted particles -- called WISPs, or weakly interacting sub-electron volt particles, by some theorists -- include one particular hypothetical elementary particle called an axion that could be a component of dark matter or dark energy in the universe.

    "If eventually found to be present, these axion particles would exert a force between a normal hunk of matter and spin-polarized matter in which the nuclei of the atoms are all set up to spin in the same direction, similar to the protons in your body used in magnetic resonance imaging," Snow said. "If present, the axion force would change the precession frequencies of the two xenon isotopes differently."

    The experiment used a test apparatus for a new type of navigation system being developed by Northrop Grumman that employs spin-polarized nuclei -- in this case the xenon isotopes 129Xe and 131Xe -- as atomic-scale gyroscopes that always point in the same direction. Applications for use of the new navigation technology are likely to emphasize small size and low power requirements, including personal and unmanned vehicle navigation in GPS-denied and GPS-challenged locations.

    IU nuclear physicist W.M. "Mike" Snow The team's final results improved on the precision of the search by two orders of magnitude for WISP-induced forces with ranges near 1 millimeter, and Snow said they expect that the sensitivity of this technique can be increased by at least two more orders of magnitude. As such, they are now preparing special nonmagnetic materials made of an alloy of gallium and indium as a precaution against the effects from magnetic fields that could also affect the xenon nuclei. And as their tests become more precise, the odds of witnessing the two isotopes respond differently to the axion force become greater.

    "A Laboratory Search for a Long-Range T-odd, P-odd Interaction From Axion-Like Particles Using Dual Species Nuclear Magnetic Resonance With Polarized 129Xe and 131Xe Gas," appeared as an "Editor's Selection" in this month's Physical Review Letters. Co-authors with Snow were C.B. Fu, E. Smith and H. Yan, all of IU Bloomington and the IU Center for Exploration of Energy and Matter, M. Bulatowicz, R. Griffith, M. Larsen and J. Mirijanian, all of Northrop Grumman, and T.G. Walker, University of Wisconsin.

    Funding for the research came from Northrup Grumman, the U.S. Department of Energy and the National Science Foundation.

    IU physics department faculty Rick Van Kooten, Steve Gottlieb, Lisa Kaufman, Rex Tayloe, Jon Urheim, and Mark Messier are leaders in an effort of 700 physicists in Minneapolis this week to explore and plan the future direction of particle physics for the next decade. The American Physical Society is organizing the meeting, known as the "Snowmass Community Summer Study 2013", this week at the University of Minnesota.

    The individual topics of study are organized into frontiers according to their method of study. High-energy physicist Van Kooten, is leading an effort within the "Energy Frontier" to assess future investigations of the recently discovered Higgs particle. Gottlieb, high-energy theorist is a leader of the "Computing Frontier" that considers the computing needs of future experiments and theoretical calculations. Within the "Intensity Frontier" where the world's most powerful proton beams are used to create neutrinos, Lisa Kaufman and Rex Tayloe are leading groups studying the fundamental nature of the neutrino and neutrino oscillations. Neutrino physicist John Urheim, is an expert panelist discussing the LBNE neutrino oscillation experiment. In addition, employing his skills speaking about physics, Mark Messier, spokesperson of the NOvA neutrino experiment, is participating in a "physics slam" competition, held on Friday night in the University of Minnesota ice arena.
