Scientists observed semi-Dirac fermion for the first time, and scientists from Pennsylvania State University and Columbia University joined hands to observe a special kind of quasi-particle-semi-Dirac fermion for the first time. Such quasi-particles have mass when moving in one direction, but lose mass when moving in the other direction. The researchers said that in-depth research on these quasi-particles is expected to promote the development of next-generation batteries, sensors and other technologies.

Shanghai thought that unnamed fund researchers bluntly said that the era of monetary fund lying and winning is over. A person from a fund company in South China said that the continuous decline in the yield of money funds means that the impact of rates is becoming more and more important. Since the beginning of this year, many money funds have announced fee reductions. Wang Menghan, an analyst at Zheshang Securities, said that compared with similar products, the advantages of money funds are tax exemption, liquidity and stable net value. Among them, for institutional customers, there are still tax exemption and liquidity demands, so there is little demand for reducing the holdings of money funds. However, for non-institutional investors, because the stability of the net value of the money fund will be obviously weakened, there is a demand to reduce the holdings of the money fund. (SSE)
