Advancing Future Quantum Science Efforts

08-27-20

Five new Department of Energy centers will apply quantum information science to emerging technologies. The centers will develop cutting-edge quantum technologies for use in a wide range of possible applications including scientific computing; fundamental physics and chemistry research; and the design of solar cells and of new materials and pharmaceuticals. Caltech faculty will participate in four of the new science centers: the Quantum Systems Accelerator, led by the Lawrence Berkeley National Laboratory, also known as Berkeley Lab; the Quantum Science Center, led by Oak Ridge National Laboratory; Q-NEXT, led by Argonne National Laboratory; and the Co-design Center for Quantum Advantage, led by Brookhaven National Laboratory.

AI for a Better Prediction COVID-19 Model

08-25-20

A team of Caltech students, led by Professor Yaser Abu-Mostafa, have developed a tool to predict the impact of COVID-19 using artificial intelligence (AI). While many models to predict the spread of a disease already exist, few if any incorporate AI, which makes predications based on observations of what is actually happening as opposed to what the model's designers think should happen. AI has the power to discover patterns hidden in data that the human eye might not recognize. [Caltech story]

Collecting Hot Carriers: New Process Harvests Excited Quasiparticles

08-12-20

Professor Harry Atwater has developed a way to eke more energy out of solar power by collecting freshly charged particles before they have an opportunity to cool off. This fundamental research could one day help scientists harvest energy from the sun more efficiently than by the natural photosynthesis used by plants. "If hot carriers, transporting more energy, could be captured, we would be able to wring three to four times as much energy from solar power," says Atwater. [Caltech story]

A Pathway to Longer-Lasting Lithium Batteries

08-06-20

The energy density of batteries have been a major challenge for consumer electronics, electric vehicles, and renewable energy sources. Professor Julia R. Greer has made a discovery that could lead to lithium-ion batteries that are both safer and more powerful. Findings provide guidance for how lithium-ion batteries, one of the most common kinds of rechargeable batteries, can safely hold up to 50 percent more energy. "Every power-requiring application would benefit from batteries with lithium instead of graphite anodes because they can power so much more," says Greer. "Lithium is lightweight, it doesn't occupy much space, and it's tremendously energy dense." [Caltech story]

Dabiri Receives Waterman Award from the National Science Foundation

08-05-20

The National Science Foundation (NSF) honors John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, with the 2020 Alan T. Waterman Award. The Alan T. Waterman Award is given to an outstanding young U.S. scientist or engineer along with a medal and other recognition. "This year's scientific pioneers are innovators who are creatively addressing some of the most challenging scientific questions," said NSF Director Sethuraman Panchanathan. "John Dabiri has looked to the fluid mechanics of sea life for inspiration to build better wind farms that appear to boost efficiency with a much smaller footprint." [NSF story] [Caltech story

Ari Rosner Develops Tool That Configures Socially-Distanced Students In Classrooms

07-31-20

Mechanical engineering student Ari Rosner, has developed an interactive Excel worksheet powered by advanced algorithms to help schools with social distancing in classrooms. Schools can plug a room’s dimensions and social distancing parameters into the worksheet, and the most efficient configuration of students for a designated classroom would automatically be mapped out. Rosner’s model situates students in rows or in a hexagonal pattern, depending on a room’s shape, in order to safely maximize space. "I cried when I saw how this worked," said Rachael Burton, the development director at a small private school in Brooklyn, New York. "I knew Ari’s mathematical chart could save our lives."

Superconducting Twisted Bilayer Graphene—Magic not Needed?

07-16-20

A new study shows that superconductivity in twisted bilayer graphene can exist away from the magic angle when coupled to a two-dimensional semiconductor. "Our observations were quite unexpected. It implies that we only scratched the surface of graphene twistronics. These are exciting times for the field," says Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science.
