Three Penn State faculty members have been elected as Fellows of the American Physical Society

UNIVERSITY PARK, Pa. – Three Penn State faculty members have been elected as Fellows of the American Physical Society (APS), the world’s largest organization dedicated to physics. The new group of fellows includes Anna Stasto, a professor of physics from Penn State; Zhaoxing Liu, professor of physics; and Adri Van Duyne, Distinguished Professor of Mechanical Engineering.

The APS Fellowship Program honors members who have advanced knowledge through original research and publication, who have made significant and innovative contributions to the application of physics to science and technology, or who have made significant contributions to the teaching of physics or to the opportunities and activities of the association, according to the APS website. . Each year the Society elects no more than one-half of 1% of its current membership to the rank of Fellow.

Stasto and Liu are both from the Eberly College of Science.

“This is a huge problem,” said Mauricio Terrones, chair of the Department of Physics at George A. and Margaret M. Downsborough, Evan Pugh University Professor and Professor of Chemistry, Materials Science and Engineering: “I am delighted that Anna and Shaoxing will be recognized with this honor.” “We are very fortunate and proud to have scholars of this caliber in the department. Their election as APS Fellows could not be more deserving.”

Mary Fricker, department chair and professor of mechanical engineering and chair of the Department of Engineering at Reiss and director of Penn State’s Center for Bioinstruments, expressed similar sentiments regarding Van Duyne.

“Professor Van Duyne is one of the world’s leading experts in the field of molecular dynamics simulations,” Fricker said. “It is great to see his significant research contributions recognized by the American Physical Society.”

Anna Stasto

Stasto, a professor of physics, was elected for his outstanding contributions to quantum chromodynamics — the theory behind the strong force in physics, which links fundamental particles known as quarks to protons, neutrons and other particles — at high energies and for the scientific status of future electron-ion colliders.

Stasto studies particle physics, with a particular focus on strong interaction theory and astroparticle and neutrino physics. She is particularly interested in studying the high-energy limits of quantum chromodynamics, where new phenomena related to large densities of quarks and gluons are expected to be observed. In the past, she has conducted research related to the so-called deep inelastic scattering of electrons onto protons, a process that has been investigated experimentally at the Circular Electron Hadron Collider in Germany. The results of her theoretical analyzes have been successfully applied to a variety of topics, including studies of the structure and function of protons; Production of heavy quarks. And produce jets of particles. She also studied the mechanisms of producing neutrinos, which are very light particles with no charge, and investigated the spread of neutrinos across the Earth. She has also been active in developing the scientific case for future electron-ion colliders.

Stasto received the US Department of Energy’s Distinguished Young Investigator Award in Nuclear Physics and was also awarded an Alfred P. Sloan Research Fellowship in recognition of her work as a young scientist involved in cutting-edge research, both in 2009.

Before joining Penn State as an assistant professor in 2008, Stasto was a research associate at Penn State from 2006 to 2008. She was a research associate at Brookhaven National Laboratory from 2004 to 2006, and was a postdoctoral fellow at the German Electron Synchrotron. (DESY) in Hamburg, Germany, from 2002 to 2004. Stasto received a master’s degree in physics from the Jagiellonian University in Poland in 1996 and a joint doctorate in theoretical physics at the Polish Academy of Sciences and Durham University in the United Kingdom. She obtained a qualification certificate in theoretical physics from the Polish Academy of Sciences in 2005.

Zhaoxing Liu

Liu, a professor of physics, was elected for his contributions to theoretical studies of topological insulators — a class of quantum materials in which electric currents flow across surfaces — and the anomalous quantum Hall effect — a phenomenon in which the current does not lose energy as it travels along the edge of the material.

Liu is a theorist in condensed matter physics, and his current research focuses on a large variety of topological states of matter, including topological insulators, anomalous quantum Hall states, topological crystalline insulators, and topological superconductors, and exploring exotic physical phenomena in these materials. In particular, he is interested in the relationship between symmetry and topological states, the interaction effect and topological and geometric effects in topological materials. Liu’s group combines theoretical studies with advanced computational methods and collaborates closely with experimental groups. He is also interested in searching for new materials with exotic properties that could have applications in electronic devices.

Before joining Penn State’s Eberly College of Science, Liu was a postdoctoral researcher with an Alexander von Humboldt Fellowship at the University of Würzburg in Germany. He also worked as a visiting scholar at Stanford University and the University of Hong Kong in China. Liu received his PhD in Physics and Bachelor’s degree in Basic Science from Tsinghua University, China, in 2009 and 2003, respectively.

Adri Van Duyn

Van Duyne, a Distinguished Professor of Mechanical Engineering, was elected for his invention and development of the Reactive Force Field (ReaxFF) potential—a powerful computational tool for exploring, developing, and optimizing the properties of materials at the atomic scale that has greatly contributed to the development of the classical reaction field of atomic simulation and bridging the gap between And experience.

Van Duyne is a leading expert in large-scale atomic modeling of a wide range of materials. The ReaxFF method he invented has been used by scientists around the world in more than 1,000 peer-reviewed publications and has been cited more than 50,000 times.

ReaxFF provides a computationally efficient alternative to simulations using quantum mechanical principles – which are extremely accurate, but also very computationally intensive. The ReaxFF framework allows for more practical simulations of the molecular dynamics found in chemically reactive materials and molecules. With this knowledge, researchers can better understand the materials they study at the nanoscale and ultimately improve their use.

The ReaxFF method has provided insights into many areas, including combustion, materials, biomaterials, polymers, batteries, and fuel cells. Van Duin is currently pursuing a project with ReaxFF centered around additive manufacturing, commonly referred to as 3D printing. In this project, Van Duyne used ReaxFF to study and optimize interactions between chromium oxide nanoparticles and a type of binding solution, which is essentially the “glue” that holds the nanoparticles together. By investigating these interactions at the nanoscale, researchers hope to build stronger 3D-printed components.

Van Duyne earned his PhD, a degree similar to a bachelor’s degree, from the University of Amsterdam and his PhD from Delft University of Technology in the Netherlands, followed by postdoctoral appointments at the University of Newcastle upon Tyne in the UK and California. Institute of Technology. He held courtesy appointments at Penn State in Chemistry, Chemical Engineering, Materials Science and Engineering, Engineering Science, and Mechanics. Van Duin is also the co-founder and CTO of RxFF_Consulting LLC, a consulting firm working on ReaxFF training and applications.
