Atomic Fractals in Metallic Glasses

09-18-15

Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues including graduate student David Chen have shown that metallic glasses has an atomic-level structure although it differs from the periodic lattices that characterize crystalline metals. "Our group has solved this paradox by showing that atoms are only arranged fractally up to a certain scale," Greer says. "Larger than that scale, clusters of atoms are packed randomly and tightly, making a fully dense material, just like a regular metal. So we can have something that is both fractal and fully dense."

Professor Bernardi Wins the Psi-K Volker Heine Young Investigator Award

09-11-15

Marco Bernardi, Assistant Professor of Applied Physics and Materials Science, has won the 2015 Psi-K Volker Heine Young Investigator Award. The award is given in recognition of an individual’s outstanding computational work in condensed-matter, materials, or nanoscience research involving electronic structure calculations. Professor Bernardi has received it for his research in first principles electronic structure calculations of the ultrafast dynamics of excited electrons in materials. His research is addressing the question of “how does an excited electron lose its energy?” which is central in a variety of fields ranging from condensed matter physics to electrical engineering and energy. Bernardi has developed and applied calculations to study the dynamics of out-of-equilibrium charge carriers, also known as hot carriers, in semiconductors and metals. [Learn more]

New, Ultrathin Optical Devices Shape Light in Exotic Ways

09-03-15

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, and colleagues have created silicon nanopillars devices capable of manipulating light in ways that are very difficult or impossible to achieve with conventional optical components. The devices are precisely arranged into a honeycomb pattern to create a "metasurface" that can control the paths and properties of passing light waves. Professor Faraon describes, "this new technology is very similar to the one used to print semiconductor chips onto silicon wafers, so you could conceivably manufacture millions of systems such as microscopes or cameras at a time."

Keith-schwab
Seeing Quantum Motion

08-31-15

Keith Schwab, Professor of Applied Physics, has found a way to observe and control the quantum motion of an object that is large enough to see. Schwab's group has learned how to cool the motion of small micrometer-scale objects to produce the quantum ground state. This quantum motion is theoretically an intrinsic part of the motion of all objects. Schwab and his colleagues designed a device that would allow them to observe this quantum motion and then manipulate it. The ability to control quantum noise could one day be used to improve the precision of very sensitive measurements, such as those designed to search for signs of gravitational waves. [Caltech Story]

Ravichandran
New EAS Division Chair Announced

08-03-15

Guruswami Ravichandran, John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering; Director, Graduate Aerospace Laboratories, has been selected as the new chair of the Division of Engineering and Applied Science (EAS) effective September 1, 2015. "I believe, based on the evaluation of the search committee and on my own interactions with him, that Ravi not only has the judgment, energy, and vision to lead the division creatively and effectively, but that he will also be an outstanding advocate for the division," said Edward Stolper, Carl and Shirley Larson Provostial Chair and William E. Leonhard Professor of Geology, in an announcement to the EAS faculty. Professor Ravichandran commented, "During my tenure, I would like to see that we attract the best faculty and students to EAS and the Institute who will enable interdisciplinary activities across Caltech and contribute to frontiers of engineering science and technology. I would like to see a more diverse body of students and faculty, who will enrich EAS and the Institute, and I would like to see EAS be at the forefront of technological revolution based on our unique ability to drive advances through basic research.” [Caltech Release]
