CHINA-BEIJING-ULTRATHIN OPTICAL CRYSTAL-INVENTION (CN)

(231219) -- BEIJING, Dec. 19, 2023 (Xinhua) -- Researchers use equipment to prepare optical crystal and test wavelength conversion at a lab in Peking University, Beijing, capital of China, Dec. 15, 2023. A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology. The research findings were recently published in the journal Physical Review Letters.

    (240624) -- BEIJING, June 24, 2024 (Xinhua) -- Xue Qikun walks in Tsinghua University in Beijing, capital of China, Oct. 17, 2017. Xue Qikun won China's top sci-tech award for the year 2023 Monday. Xue is a distinguished scientist of condensed matter physics, who has achieved multiple scientific breakthroughs. His team made the first experimental observation of the quantum anomalous Hall effect. They also discovered interface-enhanced high-temperature superconductivity in the heterostructure system, which opened up a new direction of research in the field of high-temperature superconductivity.
