AIAA To Live Stream Two Sessions From Its Fluid Dynamics Conference
Sessions Celebrate 60 Years of the Air Force Office of Scientific Research, With Focus on Hypersonics, and Achievements in Fluid Dynamics Research and Technology
The first session, “Celebrating 60 Years of the Air Force Office of Scientific Research (AFOSR): Hypersonics into the 21st Century – Research Progress Since 2001 and Future Directions in Aerothermodynamics,” will be streamed from 1:00 p.m. to 5:00 p.m. (PDT). The session will review the history and progress of hypersonic flight and its technologies, and will also look at the possible future of the enterprise. Topics include: “The AFOSR Hypersonic Strategy”; “Hypersonic Boundary-Layer Laminar-Turbulent Transition”; and “Progress and Future Prospects for Particle-Based Simulation of Hypersonic Flow.” Other technical issues relevant to advancing the art of hypersonic flight will be discussed as well. Presenters include: John D. Schmisseur, program manager, aerothermodynamics and turbulence, AFOSR; Datta V. Gaitonde, John Glenn Professor of Mechanical and Aerospace Engineering, The Ohio State University; Steven P. Schneider, professor, aeronautics and astronautics, Purdue University; Helen L. Reed, professor, Department of Aerospace Engineering, Texas A&M University; and Graham V. Candler, McKnight Presidential Professor, McKnight University Professor, and Russell J. Penrose Professor, aerospace engineering and mechanics, University of Minnesota.

Researchers report first entanglement between light and an optical atomic coherence
Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of interacting atoms in two different states. The development could help pave the way for functional, multi-node quantum networks.

The research, done at the Georgia Institute of Technology, used a new type of optical trap that simultaneously confined both ground-state and highly-excited (Rydberg) atoms of the element ribidium. The large size of the Rydberg atoms – which have a radius of about one micron instead of a usual sub-nanometer size – gives them exaggerated electromagnetic properties and allows them to interact strongly with one another.

Ferroelectric-graphene-based system could lead to improved information processing
Researchers at MIT have proposed a new system that combines ferroelectric materials – the kind often used for data storage – with graphene, a two-dimensional form of carbon known for its exceptional electronic and mechanical properties. The resulting hybrid technology could eventually lead to computer and data-storage chips that pack more components in a given area and are faster and less power-hungry.
