    • Departmental Colloquium : Magnetic Resonance Imaging with Hyperpolarized 13C, Dr. Jeremy Gordon

      When: Thursday, April 24, 2014 4:00 pm - 5:00 pm Where: Physics Auditorium (Rm. 202)

      Magnetic resonance imaging (MRI) of 13C nuclei holds the potential to probe pathology at a molecular level. These pathological changes often times precede or occur in the absence of changes in anatomy and can therefore provide valuable insight into the treatment of malignant diseases. Unfortunately, signal from endogenous 13C is indistinguishable from noise due to low receptivity, sub millimolar in-vivo concentrations, and scan time limitations.

      Recent advances now allow for >10,000 fold signal enhancement of 13C nuclei via a technique referred to as dynamic nuclear polarization (DNP), enabling the use of 13C labeled molecules to probe metabolic function non- invasively and in real-time. Nevertheless, MR imaging of hyperpolarized 13C compounds is more challenging than conventional 1H MRI, due in large part to the nature of the hyperpolarized magnetization and the need to generate images of both the substrate and the metabolic products. In this talk we will discuss the principles of hyperpolarization, the basics of MRI with hyperpolarized 13C compounds, and some of the applications of this new and exciting technique.

    • Mathematical Physics Seminar : Diagrams with divergent integrals, Robert Varley

      When: Tuesday, April 22, 2014 4:40 pm - 5:30 pm Where: Physics Building Conference Room (204B)
    • NanoSEC Seminar : Optical Metamaterials: Beyond the Linear Regime, Prof. Wenshan Cai

      When: Friday, April 18, 2014 4:00 pm - 5:00 pm Where: Riverbend Research South Laboratory Auditorium

      Metamaterials are commonly viewed as artificially-structured media capable of realizing arbitrary effective parameters, in which metals and dielectrics are delicately combined to facilitate the index contrast and plasmonic response required for a particular purpose. We aim to drive beyond this limited vision and explore the use of optical metamaterials as a generalizable platform for optoelectronic information technology: Metals will provide tailored plasmonic behavior as before, but will serve double duty by providing electrical functions including voltage input, carrier injection/extraction, and heat sinking, and dielectrics will consist of functional elements such as Kerr materials, electrooptic polymers, and p-n junctions. In this talk I will discuss our preliminary results on several topics in this category, including the electrically induced harmonic generation and optical rectification of light in a perfect metamaterial absorber, the nonlinear spectroscopy and imaging from a chiral metamaterial, and the backward phase-matching in an optical metamaterial where the fundamental and frequency- doubled waves possess opposite indices of refraction.

    • Observatory Open House : Observatory Open House, Dr. Robin Shelton and Dr. Loris Magnani

      When: Thursday, April 17, 2014 8:30 pm - 10:00 pm Where: 4th floor of the Physics bldg. or Physics Auditorium (rm. 202) if cloudy

      The Observatory Open House will be on Thursday, April 17, 2014, beginning at 8:30pm and ending at 10:00pm. If the weather is clear, then we will use the 24 inch telescope in the dome on top of the building to see the sky, especially Jupiter. If the weather is cloudy, then Dr. Loris Magnani will give a lecture in the physics auditorium (room 202). The topic of his lecture will be "The Dark Side of Astronomy:  Dark Energy and Dark Matter".  

      If the sky is clear, then visitors should go to the 4th floor of the Physics Building, where they will ascend the staircase that leads to the dome. Visitors do not need to arrive exactly at 8:30pm or before 8:30pm -- we will be open during the whole 8:30pm to 10:00pm timeframe.


    • Mathematical Physics Seminar : Perturbative QFT and its diagrams, Robert Varley

    • Ying Wai Li is the recipient of two prestigious UGA Graduate Student awards in 2013

      • Graduate Student Excellence-in-Research Award, 2013
      Initiated in 1999 to recognize the quality and significance of graduate student scholarship, these awards may be given in five areas: Fine Arts, Humanities and Letters, Life Sciences, Mathematical and Physical Sciences, and  Applied Studies.

      • Robert C. Anderson Memorial Award, 2013
      This award is given to recent Ph.D.s for outstanding research at the University or immediately after graduating. It is named for the late Robert C. Anderson, who served as UGA’s vice president for research and president of the University of Georgia Research Foundation, Inc.

      Ying Wai Li, a doctoral graduate in physics, was an outstanding graduate student researcher while at UGA, and her many accomplishments led to her current postdoctoral fellowship at Oak Ridge National Laboratory. For her PhD research project, Li worked at the interface between physics, computational science and biochemistry. She carried out very detailed simulations of the hydrophobic-polar protein folding model, which examines how proteins become functional in space. Her painstaking work led to the identification of a small number of “universal classes” of protein folding behavior. Understanding the folding behavior of proteins under diverse conditions is key to interpreting their functional properties, and Li developed a number of novel approaches to speed up the simulations and to permit her to access system sizes necessary to reveal the relevant physics. Her work explores and maps new territory, and the conclusions she has drawn may lead to new design principles for proteins or peptides used in nanotechnology and a range of real-world applications.

    • Astronomy Professor Loris Magnani to present first of six lectures in UGA's Origins Lecture Series

      Astronomy professor Loris Magnani will present the first lecture as part of UGA's Origins Lecture Series. This series of six lectures explores the origin of life, Earth, and the universe itself. All lectures in this series are intended for general audiences. Dr. Magnani will be discussing the origin of the universe at the UGA Chapel On Wednesday, January 23 at 7:00 pm. From his Origins Lecture Page:

      In this lecture I will describe how Einstein laid the foundations for  the Big Bang Theory with his Theory of General Relativity and how these ideas were  used to understand the expansion of the Universe in the 1930s.  We will look at the predictions made by the classical theory and how some startling discoveries made in the last 20 years have been incorporated into the theory.  In the process we will see how theories develop with time and new information, how particle physics has impacted cosmology and what are some of the major challenges facing the Big Bang Theory today.

      About the Origins Lecture Series:

      Since mankind’s earliest days the story of our origins has been one of fascination and inspiration.  In an effort to share that story six of UGA’s leading scientists have come together to present the latest scientific findings on everything from our humble beginnings on the plains of east Africa to the formation of the universe itself.  The Origins Lecture Series is intended for the entire Athens community.  In clear and plain language these talks are geared for those who want to know more about who we are, how we got here, and possibly, where we are going.
