High school first time takes an exam, took an examination of whole class reciprocal the first, finally however with entire school achievement of the first the university entrance exam is taken an examination of together south big physics is; Adjourn from the doctor, be in to recently again periodical of international tip learning " natural " on publish an article, this " SARS " learn bully, what revealing to us just is actual strength " counterattack " .
Recently, nanjing university 10 thousand virtuous key link group " flue type is searched " uncover secret nearly 10 thousand kinds of develop attack material is in " natural " print is published. And this article the first author, be counterattack of this actual strength " SARS " learn bully -- Nanjing university physics Tang Feng of courtyard doctor graduate student.
How to search a kind of develop to attack material? Previously, in the sea of library of of all kinds material, a kind " fishing rod " can " angle " give a kind of develop to attack material, "The person that wish swallows the bait " ; Now, "One magnify flue " OK catch the whole lot in an action, efficiency rises greatly. On Feburary 28, international learning periodical " natural " print with " use symmetry index to undertake develop attacks material is searched in the round " for the problem, published this one important research -- the scientific research group that Yuan Moxian key link teachs Nanjing university physics and co-worker of university of its Ha Fo, systematically large-scale searched whole material database, obtain a large number of develop to attack material clew, established develop to attack for the foundation with this material gene library.
10 thousand virtuous key link group Nature paper
In recent years, develop attacks the forward position heat that quanta condition is physics and material science domain. Award awarded Nobel physics 3 scientists 2016, with commending they discover corporeal develop attacks photograph and attack to change in develop the academic contribution that the respect makes. Attack to appear as new develop, people discovery, develop attacks the queer thing sex that material has groovy material to do not have, there is very large latent capacity in the respect such as electron, information and semiconductor technology.
Current, the scientist basically attacks through computational develop invariant searchs all sorts of develop to attack, efficiency of this kind of method is inferior, so foregone develop attacks material number is very limited. Consequently, develop new academic method, efficient search ideal, the develop that has economic value attacks data system is having fundamental scientific value and wide applied perspective. 10 thousand virtuous key link teach a group to bury head study, attack in search develop eventually this domain implementation breaks through material: Be based on symmetrical index theory, developed new efficient search develop to attack the academic method of material.
Develop of search of use symmetry index attacks the algorithmic flow chart of material
10 thousand virtuous key link introduce, specific for, developed namely very efficient forecast develop to attack the plan of material. University of academician of the Chinese Academy of Sciences, Nanjing teachs Xing Dingyu to express, "So efficient plan, suit to undertake to crystal library carpet type is searched very much, get develop attacks thereby material gene library. " he thinks, develop attacks material gene library will bring great advantage to experimental physicist in future, the research in the future is OK and dedicated the material in gene library, and need not resemble previously in that way " look for a needle in the ocean " .
10 thousand virtuous key link are taught and doctoral student Tang Feng discusses an issue
It is reported, a series of jobs that 10 thousand virtuous key link teach a group only then in August 2017, most begin to plan to search very novel at that time high-ranking develop to attack dielectric. According to this one efficient search develop to attack the academic method of material, 10 thousand virtuous key link teach a group to be opposite all material that be not magnetism whether develop attacks undertake classified, discovering the material of nearly 50% is develop attacks material. Then, 10897 kinds of develop that they predict computation attack material (contain Fermi there is the system that can take point of intersection near energy level) crystal structure information and electron can be taken put on the website, offer reference of person of the same trade and research. They still chose face of nearly 1000 Fermi to perhaps can take the system with nearer from Fermi face point of intersection completely quite, the research with further prophecy will be probable the ideal develop that digs disinter to suit to apply actually from which attacks material.
"The develop that gives out in the article attacks material gene library, hopeful brings vibrant follow-up test or further academic exploration. The efficient develop that they put forward attacks material search method also suits other system, if sound is subsystem, smooth subsystem, magnetic material. Can anticipate, extensive search and a kind of trend that forecast material to will become science of agglomeration condition physics, material, to relevant domain development will have urge action actively. " Xing Dingyu expresses.
The Tang Feng of doctoral graduate student of laboratory of state of Nanjing small structure is the first author. Science of artificial small structure and technology innovate in coordination assistance of Yao barge engineer undertakes large-scale computation and construction develop attack material website.
Accepting when interviewing, tang Feng told about him once exam of high school first time took an examination of past of first of whole class reciprocal, the condition reveal everything that graduation delay, special angst worries about before also graduating him doctor. He expresses, "It is the most important to do scientific research is to accumulate " , "If people says you are no good this, I feel you should prove to look to him, actually you actually very row " .
