EAS Professors were among a small group of Caltech scientists and engineering who have won federal grants for research in quantum computing, and quantum networks. Professor Nadj-Perge (lead PI) along with co-PIs Professors Marco Bernardi and Andrei Faraon as well as co-investigator Professor Julia Greer have received funding for the program ”Quantum States in Layered Heterostructures Controlled by Electrostatic Fields and Strain," which is administered within the U.S. Department of Energy's Basic Energy Sciences division. Professor Austin Minnich is a co-PI of the program, "Quantum simulation of materials and molecules using quantum computation," which is part of the National Science Foundation's Research Advanced by Interdisciplinary Science and Engineering (RAISE)-Transformational Advances in Quantum Systems (TAQS) effort.

Xiaoyue Ni, a materials science graduate student working with Professor Julia Greer, has shown that metals undergo permanent deformation even prior to yielding—the threshold at which a material under strain becomes permanently deformed. "What Xiaoyue's data are showing is that from the first moment you start deforming it, the dislocations start being active," Greer says. Now that we know how to do this, we can probe a variety of different classes of materials. [Caltech story]

Researchers in the lab of Julia R. Greer, Professor of Materials Science and Mechanics, have recently found that diatom shells have the highest specific strength—the strength at which a structure breaks with respect to its density—of any known biological material, including bone, antlers, and teeth.

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."

In celebration of Women’s History Month, influential women leaders from the Jet Propulsion Laboratory (JPL) and Caltech gathered at the JPL von Karman auditorium. Present at the event, entitled Women Making History, were the 2015 honorees for Women@JPL as well as Caltech faculty and staff. It was an opportunity for women at different stages of their career to meet and network. EAS faculty were represented by Professors Bordoni, Greer, and Hunt.  The JPL Advisory Council for Women was the lead organizer of the event.

Professor Julia Greer’s work on nanolattices is part of the 2015 MIT Technology Review’s 10 Breakthrough Technologies List. The list identifies the ten milestones from the past year that solve difficult problems or create powerful new ways of using technology. Professor Greer was selected for her work on nanomaterials and specifically “materials whose structures can be precisely tailored so they are strong yet flexible and extremely light.” [Learn more]
