What variations did the vice president of Tsinghua University discover that rewrites physics?

Hello, the scientific research team led by Mr. Xue Qikun, Vice President of Tsinghua University, has discovered the "quantum anomalous Hall effect" for the first time in recorded human history, which has a completely different physical nature from the known quantum Hall effect and is a new quantum effect. (Encyclopedia related entry: In 2013, an experimental team led by Academician Xue Qikun of Tsinghua University and composed of the Department of Physics of Tsinghua University and the Institute of Physics of the Chinese Academy of Sciences observed the quantum anomalous Hall effect for the first time.)

The results of this study were published on March 14, 2013 in the journal Science. The existing quantum Hall effect requires a very strong magnetic field, "the equivalent of 10 magnets the size of a computer, which is not only bulky, but also expensive, and not suitable for personal computers and laptops." ”）

The significance of this discovery at present is that quantum Hall states can be realized in zero magnetic fields without any external magnetic field, which is easier to be applied to electronic devices required by people in daily life, and can be used to prepare high-speed electronic devices with low energy consumption.

The current difficulty is that the actual implementation also needs to be at extremely low temperatures, which cannot be directly used in daily electronic devices, and efforts are being made to increase the lower temperature limit.

In July 2017, at Tsinghua Lecture Hall, Shi Yigong gave a lecture on the theme of "The Beauty of Structure" to more than 200 foreign students. From Rong Hong, the "father of Chinese students", to the new discovery of gravitational waves in 2016, he gave a wonderful speech, which caused lasting and warm applause from the audience.

It has always been Shi Yigong's wish to let the world see China.

On August 14, 2016, the 31st National Youth Science and Technology Innovation Competition opened in Shanghai, and Shi Yigong, vice chairman of the China Association for Science and Technology and academician of the Chinese Academy of Sciences, shared his scientific research experience and growth insights at the opening ceremony to encourage young people to devote themselves to the cause of science.

Shi Yigong said that this sense of responsibility for the motherland is related to personal experience. When he was in his third year of college, his father died in a car accident, and Shi Yigong suffered a big blow. Far away in a foreign country, he never forgot his father, who graduated from Harbin Institute of Technology, and during the Cultural Revolution to the countryside, he never spared no effort to help his neighbors and villagers, and never gave up his ideal return heart and mind.

This decided that he would resign as a tenured professor at Princeton University and return to China.

I just want to stay in China and make a difference in China. Shi Yigong said.

After returning to China, in order to make the most advanced achievements and improve the country's relevant science and technology to the world-class level, Shi Yigong raced against time, working in the laboratory for more than ten hours a day, sometimes only sleeping 4 hours a day. After returning to China for ten years, my hard work has finally paid off handsomely!

Tsinghua University's life science research level has achieved a huge leap forward, and it can wrestle with world-renowned universities. Shi Yigong said proudly.

He told the young people: "In today's big picture, your generation has a heavy responsibility. I encourage you to take the world as your own responsibility, pursue the most cutting-edge science and create the most advanced technology without hesitation, and make your own contributions to the rise of China and human civilization! ”

to bring change to China" is Shi Yigong's original intention to never change.

Academician Xue Qikun: We have discovered superconducting materials that can allow radar to see 200 kilometers more.

It is understood that Shi Yigong's wife is also an undergraduate student of the Department of Biology of Tsinghua University and a doctor from Johns Hopkins University, and they have a pair of dragon and phoenix fetal daughters.

Academician Gu Binglin has long been committed to the research of physics and materials science and the cultivation of high-level talents, and has made many important achievements in the direction of condensed matter physics. He has published more than 220 academic papers, including more than 200 SCIs. He has won many awards such as the Ho Liang Ho Li Science and Technology Progress Award, the second prize of the National Natural Science Award, the first prize of the Natural Science Award of Chinese Universities, the second prize of the Science and Technology Progress Award of the Ministry of Education (State Education Commission) for four times, the second prize of the Beijing Science and Technology Progress Award, the State Science and Technology Commission's "Important Contribution to the Work of the Seventh Five-Year Plan Period", and the special prize of Baosteel Education ** Outstanding Teacher.

Academician Gu Binglin has trained more than 20 doctoral students, one of whom has won the National Excellent Doctoral Degree Award, six of whom have won the Tsinghua University Outstanding Doctoral Degree Award, four of whom have been rated as "Outstanding Doctoral Graduates of Tsinghua University", and two of whom have been awarded the "Top Ten Outstanding Graduate Students of Tsinghua University".
