New progress in antiferromagnetic spin transport theory
Science and Technology Daily (reporter Wu Changfeng) On June 12, the reporter learned from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences that Shao Dingfu, a researcher and collaborator of the Institute of Solid State of the Chinese Academy of Sciences, predicted that the spin neutral current in the antiferromagnetic material would carry a special "Nair spin current", and based on this effect, a theoretical scheme of high-performance fully electrically controlled antiferromagnetic tunnel junction was proposed. The relevant research results were recently published in the Physical Review Letters...
The "splitting" phonon exhibits quantum properties
Science and Technology Daily (reporter Zhang Jiaxin) A few days ago, a team led by Professor Andrew Cleland of the Pritzker School of Molecular Engineering (PME) of the University of Chicago used a device called an acoustic beam splitter to "split" phonons, thereby demonstrating their quantum properties. They demonstrated that beam splitters can be used to induce a special quantum superposition state of a phonon and further generate interference between two phonons...
Shenzhen Virtual power plant basically has the function of physical power plant
Our report (Yang Jingjing) recently, Shenzhen Power Supply Bureau of China Southern Power Grid, in conjunction with the South Power Grid Research Institute, used 5G special chip technology to verify the frequency modulation technology of Virtual power plant for the first time in China, which marks that Virtual power plant in Shenzhen basically has the function of a physical power plant, which will help to improve the city's power security capability and new energy consumption capacity.Since China Southern Power Grid built the Virtual power plant management platform in Shenzhen at the end of 2021, it has repeatedly used the platform at key nodes to ensure power and electricity balance in Shenzhen...
