It is unfortunate that my first post of the New Year is about a sad news from Dec. of 2018. Prominent Standford physicist, Shoucheng Zhang passed away in early Dec. of an apparent suicide. He was only 55, and according to his family, has been suffering from bouts of depression. But what triggers this report is the possible connection between him and US-China relation, which, btw, is purely a rumor right now.
Zhang was originally recruited in 2008 under the Thousand Talents program — a CCP effort to attract top scientists from overseas to work in China — to conduct research at Tsinghua University in Beijing. Zhang was active in helping U.S.-trained Chinese researchers return home, and expressed his desire to help “bring back the front-lines of research to China” in a recent interview with Chinese news portal Sina.
Zhang’s venture capital firm Digital Horizon Capital (DHVC), formerly known as Danhua Capital, was recently linked to China’s “Made in China 2025” technology dominance program in a Nov. 30 U.S. Trade Representative (USTR) report. According to the report, venture capital firms like DHVC are ultimately aimed at allowing China to access vital technology from U.S. startups. Zhang’s firm lists 113 U.S. companies in its portfolio, most falling within emerging sectors that the Chinese government has identified as strategic priorities.
The “Made in China 2025” program combines economic espionage and aggressive business acquisitions to aid China’s quest to become a tech manufacturing superpower, the USTR report continues. The program was launched in 2015 and has been cited by the Trump administration as evidence that the Chinese government is engaged in a strategic effort to steal American technological expertise.
I have absolutely no knowledge on any of these. I can only mourn the brilliant mind that we have lost.
I first heard of "S.C. Zhang" when I was still working as a grad student in condensed matter physics, especially on the high-Tc superconductors. He published this paper in Science, authored by him alone, on the SO5 symmetry for the basis of a unified theory of superconductivity and antiferromagntism[1]. That publication created quite a shakeup in condensed matter theory world at that time.
It was a bit later that I learned that he came out of an expertise in elementary particle physics, and switched fields to go dabble into condensed matter (see, kids? I told you that various topics in physics are connected and interrelated!). Of course, his latest ground-breaking work was the initial proposal for topological insulators[2]. This was Nobel Prize-caliber work, in my opinion.
Besides that, I've often cited one of his writings when the issue of emergent phenomena comes up.[3] As someone with a training in high energy/elementary particle, he definitely had the expertise to talk about both sides of the coin: reductionism versus emergent phenomenon.
Whatever the circumstances are surrounding his death, we have lost a brilliant physicist. If topological insulators become the rich playground for physicists and engineers in the years to come, as it is expected to, I hope the world remembers his name as someone who was responsible for this advancement.

An error: Shoucheng had been at Stanford as a professor since '93 and earned his PhD in '87. His science article was seminal work produced as an assistant professor.
Yeah, so what's the "error"? I didn't say anything about his status during the times that I heard about him. I said *I* was a graduate student when I first heard about his SO5 symmetry proposal.
