A team, lead by Simon Billinge, has discovered an unusual form of electronic order in a new family of unconventional superconductors. The finding, described in Nature Communications, establishes an unexpected connection between this new group of titanium-oxypnictide superconductors and the more familiar cuprates and iron-pnictides, providing scientists with a new family of materials from which they can gain deeper insights into the mysteries of high-temperature superconductivity.
Five APAM faculty members (Chris Marianetti, Michael Mauel, Adam Sobel, Latha Venkataraman, and Chris Wiggins), made presentations during the SEAS 150th Anniversary Symposium on Friday, November 14, from 2:00-4:00 PM, in Roone Arledge Auditorium in Lerner Hall. Nov. 14 Symposium Showcases 150 Years of Innovation, Then and Now
"The agreement between President Barack Obama and President Xi Jinping of China to reduce greenhouse gas emissions is the most important advance in the several decades-long history of international climate negotiations. It has been greeted with rage by those in Congress whose positions on the science are denialist or evasive ("I am not a scientist"). Their criticisms are specious and predictable. But while most climate scientists I know are still sharing a period of joy following its announcement, some substantive criticisms of the agreement have also been raised. I want to address two of them here."
“We live in an age where computational science is becoming a nascent interdisciplinary field and the advent of computing technology is rapidly transforming how mathematics get used in applications. What has intrigued me the most in my research are the challenging questions that have strong practical motivations and demand new mathematical and computational tools for their solutions,” says Qiang Du, the Fu Foundation Professor of Applied Mathematics.
Ever since the dawn of the electronic age, science has been on a quest for miniaturization, making transistors smaller in order to integrate many into a circuit and further miniaturizing to build microprocessors. The potential for further miniaturization is predicated on physics: The tiniest transistors must still be large enough to control the on or off flow of electrons. The smallest transistors that can be envisioned consist of just a few atoms or a small molecule. The potential for making such small electronic circuits has captivated Latha Venkataraman, associate professor of applied physics.
