On December 1, 2018 (October 24, 2018 lunar calendar), Professor Zhang Shousheng, an American Chinese physicist, passed away. On December 1, 2018 local time, Zhang Shousheng, an American Chinese physicist, tenured professor at Stanford University, academician of the American Academy of Sciences, foreign academician of the Chinese Academy of Sciences, and winner of the 2017 People's Republic of China International Science and Technology Cooperation Award, Professor Zhang Shousheng passed away at the age of 55. Zhang Shousheng's main contributions include research in the fields of topological insulators, quantum spin Hall effect, spintronics, and high-temperature superconductivity. In 2007, his discovery of the "quantum spin Hall effect" was named one of the "top ten important scientific breakthroughs in the world" by Science magazine. Zhang is also the founder of Danhua Capital. Danhua Capital said in an email that Professor Zhang Shousheng passed away abruptly on December 1, 2018. Danhua Capital is still operating normally. Professor Zhang's family and Danhua Capital employees are in great grief. Zhang Shousheng's family did not disclose the cause of death. Danhua Capital officials also said they were unaware. Danhua Capital Email Danhua Capital Email Zhang Shousheng is a professor of physics at Stanford University, a member of the National Academy of Sciences, a member of the American Academy of Arts and Sciences, and a foreign member of the Chinese Academy of Sciences. In 1983, he received a bachelor's degree from the Free University of Berlin, Germany, and a doctorate from the State University of New York at Stony Brook in 1987. From 1987 to 1989, he served as a postdoctoral researcher at the Santa Barbara Institute for Theoretical Physics in the United States. From 1989 to 1993, he served as a senior researcher at the IBM Almaden Research Center. In 1993, he was employed by the Department of Physics of Stanford University. His main research areas are condensed matter physics, with a focus on topological insulators. He has achieved a large number of world-class original innovations in high-temperature superconductivity, quantum Hall effect, spintronics, and strongly correlated electronic systems. For his pioneering research on the quantum spin Hall effect and topological insulators, he won the European Physics Prize in 2010, the Oliver Buckley Prize of the American Physical Society in 2012, the Dirac Medal and Prize of the International Center for Theoretical Physics under UNESCO in 2012, and the Frontier Prize in Physics (PhysicsFrontierPrize) in 2013. He took the stage to accept the award with the famous physicist Hawking. He won the BenjaminFranklinMedal in 2014. Zhang Shousheng's angel-funded Stanford University startup VMWare is a leader in the cloud computing industry, with a market value of up to $48 billion. For many years, Professor Zhang Shousheng has worked hard to promote scientific and technological exchanges between China and the United States. In 2013, he founded Danhua Capital, which focuses on investing in innovative companies from Stanford University and Silicon Valley. Its investment directions include artificial intelligence, big data, augmented/virtual reality, genetic medicine and other industries. The new theoretical research on the "Quantum Spin Hall Effect" proposed by the leadership team of Chinese professor Zhang Shousheng was included in one of the major scientific discoveries of Science magazine in 2007.
