Formal Lecture

I was formally introduced to the noble gases in high school chemistry class, but they were a boring lot and we mostly ignored them. I don’t remember them even being mentioned during college or graduate school. My real affair began in the fall of 1958 at the Brookhaven National Laboratory. I had taken a postdoctoral appointment there to work with one of the foremost nuclear chemists in the country. In 1958 there was Glenn Seaborg in California, Nate Sugarman at the University of Chicago, and Gert Friedlander at Brookhaven. I had finished my PhD work on nuclear reactions at Oak Ridge, and applied to both Chicago and Brookhaven—California was just too far away—with Brookhaven as my clear favorite: it had the world’s biggest atom smasher, the Cosmotron, with 3 Bev of energy, while Chicago had only a few-hundred-Mev machine. So in the spring of 1958 I set off on my first interview trip, hitting Brookhaven first. One of the staff scientists took me around the lab, introducing me to the others. Whenever someone tried to ask me about my research, he shut them off, which I thought strange. And then at eleven o’clock we walked through a door and suddenly there was a room filled with the entire chemistry department looking at me, and my host stopped at the lectern just long enough to say, “Our speaker today is David Fisher, who will tell us about his work on the nuclear reactions induced by nitrogen on sulphur.” Everyone clapped politely, my host sat down, and I stood there like an idiot. I hadn’t had any idea I’d be expected to give a formal lecture to the greatest scientists I had ever met. I hadn’t prepared anything. I quickly considered my options. I could turn and flee through the door I had entered. I could drop dead. I could— There wasn’t anything else. Those were my only options. Or, oh yeah, I could begin to talk.

A full-spectrum solar energy system is being designed by a research team lead by Oak Ridge National Laboratory and the University of Nevada, Reno. [1,2] The benchmark collector/receiver and prototype thermophotovoltaic (TPV) array have been built [3], so the work performed here is to match the two systems together for optimal performance. It is shown that a hollow, rectangular-shaped non-imaging (NI) device only 23 cm long can effectively distribute the IR flux incident on the TPV array mounted behind the secondary mirror. Results of the ray-tracing analysis of the different systems tested are presented.

Abstract Thirty three years ago, because of the dramatic increase in the power and utility of computer simulations, The University of Georgia formed the first institutional unit devoted to the application of simulations in research and teaching: The Center for Simulational Physics. Then, as the international simulations community expanded further, we sensed the need for a meeting place for both experienced simulators and newcomers to discuss inventive algorithms and recent results in an environment that promoted lively discussion. As a consequence, the Center for Simulational Physics established an annual workshop series on Recent Developments in Computer Simulation Studies in Condensed Matter Physics. This year’s highly interactive workshop was the 32nd in the series marking our efforts to promote high quality research in simulational physics. The continued interest shown by the scientific community amply demonstrates the useful purpose that these meetings have served. The latest workshop was held at The University of Georgia from February 18-22, 2019. These Proceedings provide a “status report” on a number of important topics. This on-line “volume” is published with the goal of timely dissemination of the material to a wider audience. These Proceedings contain both invited papers and contributed presentations on problems in both classical and quantum condensed matter physics. The Workshop was prefaced by a special tutorial presented by colleagues from Oak Ridgr National Laboratory on a powerful software suite: OWL (Oak Ridge Wang-Landau). The first manuscript in this Proceedings is devoted to this tutorial material. The Workshop topics, as usual, ranged from hard and soft condensed matter to biologically inspired problems and purely methodological advances. We hope that readers will benefit from specialized results as well as profit from exposure to new algorithms, methods of analysis, and conceptual developments. D. P. Landau M. Bachmann S. P.

ABSTRACTThe advantages that silicon carbide (SiC) based power electronic devices offer are being realized by using prototype or experimental devices in many different power applications ranging from medium voltage to high voltage or for high temperature or high switching frequency applications. The main advantages of using SiC-based devices are reduced thermal management requirements and smaller passive components which result in higher power density. An overview of the SiC research effort at Oak Ridge National Laboratory (ORNL) and The University of Tennessee (UT) is presented in this paper.

Walter Greiner (29 October 1935 - 6 October 2016) was a German theoretical physicist. His scientific research interests include the thematic areas of atomic physics, heavy ion physics, nuclear physics, elementary particle physics (particularly quantum electrodynamics and quantum chromodynamics). He is most known in Germany for his series of books in theoretical physics, but he is also well known around the world. Greiner was born on October 29, 1935, in Neuenbau, Sonnenberg, Germany. He studied physics at the University of Frankfurt (Goethe University in Frankfurt Am Main), receiving in this institution a BSci in physics and a Master’s degree in 1960 with a thesis on plasma-reactors, and a PhD in 1961 at the University of Freiburg under Hans Marshal, with a thesis on the nuclear polarization in [Formula: see text]-mesic atoms. During the period of 1962 to 1964 he was assistant professor at the University of Maryland, followed by a position as research associate at the University of Freiburg, in 1964. Starting in 1965, he became a full professor at the Institute for Theoretical Physics at Goethe University until 2003. Greiner has been a visiting professor to many universities and laboratories, including Florida State University, the University of Virginia, the University of California, the University of Melbourne, Vanderbilt University, Yale University, Oak Ridge National Laboratory and Los Alamos National Laboratory. In 2003, with Wolf Singer, he was the founding Director of the Frankfurt Institute for Advanced Studies (FIAS), and gave lectures and seminars in elementary particle physics. He died on October 6, 2016 at the age of 80. Walter Greiner was an excellent teacher, researcher, friend. And he was a great supporter of the series of events known by the acronyms IWARA - International Workshop on Astronomy and Relativistic Astrophysics, STARS - Caribbean Symposium on Cosmology, Gravitation, Nuclear and Astroparticle Physics, and SMFNS - International Symposium on Strong Electromagnetic Fields and Neutron Stars. Walter Greiner left us. But his memory will remain always alive among us who have had the privilege of knowing him and enjoy his wisdom and joy of living.

First Time

The additive manufacturing integrated energy (AMIE) demonstration utilized three-dimensional (3D) printing as an enabling technology in the pursuit of construction methods that use less material, create less waste, and require less energy to build and operate. Developed by Oak Ridge National Laboratory (ORNL) in collaboration with the Governor's Chair for Energy and Urbanism, a research partnership of the University of Tennessee (UT) and ORNL led by Skidmore, Owings & Merrill LLP (SOM), AMIE embodies a suite of innovations demonstrating a transformative future for designing, constructing, and operating buildings. Subsequent, independent UT College of Architecture and Design studios taught in collaboration with SOM professionals also explored forms and shapes based on biological systems that naturally integrate structure and enclosure. AMIE, a compact microdwelling developed by ORNL research scientists and SOM designers, incorporates next-generation modified atmosphere insulation (MAI), self-shading windows, and the ability to produce, store, and share solar power with a paired hybrid vehicle. It establishes for the first time, a platform for investigating solutions integrating the energy systems in buildings, vehicles, and the power grid. The project was built with broad-based support from local industry and national material suppliers. Designed and constructed in a span of only 9 months, AMIE 1.0 serves as an example of the rapid innovation that can be accomplished when research, design, academic, and industrial partners work in collaboration toward the common goal of a more sustainable and resilient built environment.

Beam Deposition

Ion beam processing of materials has a tradition at Oak Ridge National Laboratory that is as old as the laboratory itself. Consequently, when we began looking for a competitive way to participate in the excitement and new physics beginning to emerge from the fabrication and study of artificially structured materials, it was natural to look for a growth technique that incorporated ion beam processing. Our division, the Solid State Division, has a variety of ion implantation and ion beam analysis accelerators which are integrated with pulsed-laser sources into ultrahigh vacuum (UHV) surface analysis and processing chambers. These facilities allow us to do ion beam and laser processing of materials in UHV at temperatures from liquid helium to several hundred degrees centigrade and to study these alterations in situ by a variety of ion beam (ion scattering, ion channeling, nuclear reactions, etc.) and surface analysis (low energy electron diffraction, Auger, etc.) techniques. Since isotope separation has been done continually at ORNL for almost 45 years, the idea and advantages for altering this technique to do materials fabrication in UHV were immediately obvious. In the following article we will briefly review the history of the ion beam deposition (IBD) concept, describe our preliminary apparatus, and point out the inherent advantages of IBD for fabricating and studying artificially structured materials. Recent results obtained by IBD will be presented.
