-First Chinese physicist honored with the 2024 Oliver E. Buckley Prize for Condensed Matter Physics

Professor Qikun Xue of Tsinghua University and Professor Ashvin Vishwanath of Harvard University won the award for their groundbreaking advances in topological quantum materials research.

BEIJING, Oct. 26, 2023 /PRNewswire/ -- Professor Qikun Xue, an academician of the Chinese Academy of Sciences, professor of Tsinghua University and president of Southern University of Science and Technology, has been awarded the Oliver E. Buckley Condensed Matter Physics Prize 2024, being the first physicist of Chinese nationality to obtain this honor. Together with Professor Ashvin Vishwanath of Harvard University, he was recognized "for their innovative theoretical and experimental studies on the collective electronic properties of materials that reflect topological aspects of their band structure."

Professor Xue commented, "This achievement is the fruit of China's steady growth in scientific and technological strength and long-term accumulation of basic scientific research since China's reform and opening up began four decades ago. This honor belongs to every researcher of the team, and to all Chinese scientists."

Since 2009, Professor Xue has led a collaborative research effort with research groups from Tsinghua University, the Institute of Physics of the Chinese Academy of Sciences, and Stanford University to address the formidable challenge of experimentally realizing the Hall effect. quantum anomalous (QAH). Overcoming numerous obstacles and setbacks, at the end of 2012 they achieved an important scientific milestone by becoming the first in the world to experimentally observe the QAH effect in magnetic topological insulators.

Professor Xue's groundbreaking discoveries have significantly advanced the field of physics, opening new avenues for global condensed matter research. The practical implications are equally promising, as the QAH effect and its dissipationless edge states have the potential to revolutionize low-energy electronic devices in the future.

In addition to topological quantum materials, Professor Xue also promotes scientific research and development in the fields of superconductivity and high-temperature superconductivity, which have also received continuous attention from generations of physicists for more than a hundred years.

In 2012, Professor Xue, leading a research team from the Department of Physics, Tsinghua University, discovered high-temperature superconductivity in a single unit cell FeSe film grown on a SrTiO substrate. This discovery, reported in a paper published in 2012, challenged the common understanding of high-temperature superconductivity and proposed a unique and innovative perspective, manifesting the exploratory spirit of Chinese scientists.
