2022年5月13日，beat365官方网站學術論壇2022年春季學期第三講（總第十五講）在線上成功舉行。德國斯圖加特大學Jörg Wrachtrup教授應邀做了題為“二維和三維材料中的自旋相關的量子物理”（Quantum Physics with Spins in 2D and 3D Materials）的學術報告。本次論壇由beat365量子材料科學中心教授、輕元素先進材料研究中心主任江穎主持。本次講座ZOOM會議室上線100餘人，通過蔻享學術平台觀看直播的觀衆逾4000人次。

Jörg Wrachtrup教授着重闡述了基于金剛石氮-空位色心（NV center）的量子傳感技術的原理，及其在二維和三維材料中關于電子/核自旋探測與調控的應用。首先，NV可以直接通過熒光強度讀取其自旋量子态，得益于NV優異的相幹性，研究者可以在室溫大氣下實現單個電子/核自旋和元電荷的探測靈敏度；将金剛石針尖結合原子力顯微鏡系統，可實現二維磁性材料的納米尺度磁成像，并突破傳統磁光探測技術的空間分辨極限，例如，該技術清楚地揭示了轉角CrI3的摩爾磁序。進一步，借助先進的相幹操縱和量子算法，通過NV色心可以實現單層氮化硼材料的納米級核磁共振探測。最後，Wrachtrup教授詳細介紹了利用NV色心實現原子核自旋超極化的工作原理，展示其在二維自旋系統（如氮化硼的核自旋網絡）中的應用，并對其在未來實現基于自旋網絡的量子模拟進行了展望。

報告結束後，參會師生圍繞納米尺度核磁共振和原子核自旋超極化等工作踴躍提問，Jörg Wrachtrup教授一一給予了深入淺出的解答。

報告人簡介：

Jörg Wrachtrup, professor and director of the 3rd Institute of Physics (since 2000) and the Center for Applied Quantum Technology (since 2016), both of the University of Stuttgart, as well as Max Planck fellow at the MPI for Solid State Research Stuttgart, has pioneered the field of single-spin physics by initiating the very first single electron and subsequently the first single nuclear spins experiments. By combining optics and spin resonance, he discovered defects in insulators, most notably defects in diamond, as a valuable system for quantum information processing in a novel type of quantum sensor for electric and magnetic fields. He and his group pioneered application of these novel sensor techniques. His current research interest is geared towards application of quantum enhanced sensing in biomedical as well as material sciences.

Professor Wrachtrup has published more than 300 papers in refereed journals with numerous Nature and Science papers, plus reviews in both journals over the past years. In 2011 and 2017, he was awarded two Advanced Research Grants of the European Research Council, in 2012 he received the Leibniz Prize of the German Science Foundation, the Bruker Prize in 2013 and the Max Planck Research Award in 2014. Jörg Wrachtrup has been awarded the Europhysics Prize Award of the European Physical Society and the Gold medal of the International Society for Electron Spin Resonance in 2020. He is a member of the Berlin Brandenburg Academy of Science and has continuously been listed as a “Highly Cited Researcher” since 2014.
