The Nature published two of Cao Yuan’s papers on Graphene in a row again in May 2020. This was not the first time that Cao Yuan shocked the world in this way. As early as 2018, Nature also published two papers on graphene with Cao Yuan as the first author. Immediately after the papers was published, it caused a huge response in the entire physics community. At that time, some reports claimed that "Cao Yuan solved the problem that plagued the world for 107 years."
On May 6, London time, in the latest issue of Nature magazine, a Chinese teenager published two papers in a row, drawing the world's attention. This talented young man is Cao Yuan. If you are a technology enthusiast, you must be familiar with his name! Cao Yuan, who was born in 1996, was admitted to the Junior Class of the University of Science and Technology of China at the age of 14 and was selected into the Yan Jici Physics Class. After graduating, he went to the United States to pursue a doctorate degree at MIT. Among the top ten scientific figures in the world released by Nature in 2018, he was only 22 years old at that time, but ranking first in the list!
In the latest issue of Nature, Cao Yuan, and his doctoral tutor Pablo Jarillo-Herrero, published two Nature papers in succession, introducing new breakthroughs in the study of magic angle graphene.
Nature is recognized as one of the three top scientific journals in the world. The kill rate is as high as 90%, which is equivalent to 10 scientists submitting papers together, but only 1 person may be selected. So we believe Cao Yuan's paper is not the kind of paper that just mixes graphene with some crap to measure properties and dare to show around.
In the first paper, Cao Yuan and his colleagues extended the characteristics of the magic angle to other two-dimensional research systems by controlling the torsion angle. The results of this study have played an important role in exploring the related phase states of twist angle and electric field control in the multiplanar twisted superlattice.
Cao Yuan is the first author of this paper and corresponding author with the tutor. Here the corresponding author is usually a professor or the team leader. Cao Yuan became a corresponding author, indicating that he is one of the main creative contributors to the paper.
In another paper, Cao Yuan was the first author of the article alongside two other authors. Cao Yuan and his colleagues studied the distribution information of the twist angle.
The research object of this article is changed to hexagonal boron nitride (hBN) encapsulated MATBG. A nanometer-scale tip-scanning superconducting quantum interference device (SQUID-on-tip) was used to obtain a tomographic image of the Landau level in the quantum Hall state, and a local θ change map was drawn.
It can be said that the appearance of these two papers locks Cao Yuan's important position in the field of graphene once again!
The Nature also published two of Cao Yuan’s papers on Graphene in 2018.
Actually this was not the first time that Cao Yuan shocked the world in this way.
As early as 2018, Nature also published two papers on graphene with Cao Yuan as the first author. Immediately after the papers was published, it caused a huge response in the entire physics community. At that time, some reports claimed that "Cao Yuan solved the problem that plagued the world for 107 years."
Why can Cao Yuan's papers conquered the discerning judges of the scientific journal Nature, and published two papers in row? That story will have to start from 100 years ago.
At that time, due to the resistance of traditional conductors, there was always a lot of energy loss during the transmission from the power stations to the users. If you can solve this problem, it is equivalent to saving a lot of resources for all the world! In order to find out a conductor that minimizes energy loss, scientists have been distressed for more than 100 years.
In 1911, Dutch physicist Heike Kamerlingh Onnes discovered that when mercury is cooled to -269 ℃, the resistance will be reduced to zero and energy consumption will be fully minimized. This is the first time humans discovered the existence of super-conductors! In 1913, Onnes also found that tin and lead have superconductivity, and won the Nobel Prize in the same year.

By 1986, German physicists Bernoz and Mueller discovered a copper oxide, which can reach the superconducting state at about -140 ℃, temperature was much higher than before. Therefore, Mueller and Bernoz also won the 1987 Nobel Prize in Physics. Although there were new discoveries in the field of superconductivity, none of the materials can leave the laboratory and jump into the practical usage.

Even Nobel Prize winner Robert Laughlin once said: Physicists have been wandering in darkness (superconducting research) for 30 years.

But it doesn't matter, a breakthrough appeared soon! August 2017 was the historical time! Cao Yuan and his team discovered a way to make graphene superconducting. As long as the two layers of graphene are rotated to a specific "magic angle" (1.1°), they can conduct electrons with zero resistance and immediately exhibit superconducting properties.
This news detonated the world instantly. Nature would certainly not miss to notice Cao Yuan's discovery. Within a day, Nature published two of Cao Yuan's papers on graphene superconductivity. At that time, some netizens commented: Nature should be honored to publish the paper of Cao Yuan's team. After all, when received the manuscript, Nature couldn't wait to typeset it before posting it online.
Cao Yuan was a talented boy since childhood
He has always been a genius in the eyes of others.
In 1996, Cao Yuan was born in Chengdu, Sichuan. He was very smart since he was a child. As soon as the teacher asked a question, he could answer it before the words ended. Later the family moved to Shenzhen. He also liked to study electronic products and often sneaked to Huaqiang North Commercial Area in Shenzhen. He would also buy a lot of electronic components to study electronic circuits.
He was not only an electronic geek, but also liked to do chemical experiments. Because of curiosity, he once stole his mother's silver bracelet and ran to the school's laboratory to try to synthesize silver nitrate with nitric acid. After knowing this, his headmaster didn't criticize him, and thought he was a rare talent.
It took Cao Yuan only two years to finish junior and high school education, and then attended the junior class of the Chinese University of Science and Technology with a score of 699 in the college entrance examination. And in 2010, when he was 14 years old, he was selected for the most outstanding "Yan Jici Physics Talent Class". The main goal of this class is to cultivate high-level elite talents with a solid physical foundation, proficiency in physical research methods, a passion for physical science research, and continuing to work in physics or related fields after graduation.
Even in the genius youth class, Cao Yuan is still outstanding. He often asked some strange questions to discuss with the professors. Even Professor Ding Zejun from the School of Physics, known as "Physical Madman", praised him: "A very smart guy." Another professor Zeng Changgan also greatly appreciated Cao Yuan: "(During his undergraduate studies), he also published a PRB theory article in our laboratory. At that time, I thought he was too brilliant."

He was also exchanged to the University of Michigan and Oxford University. In 2014, under the recommendation of his tutor, he went to the Massachusetts Institute of Technology for further study. In this way, four years later, he became the youngest Chinese to publish a paper in Nature.
Today, hundreds of world-class scholars are trying to extend Cao Yuan’s research achievements. Once succeeded, hundreds of billions of dollars will be saved in the world's energy industry. Nature introduced him in the annual article as: "An outstanding scientist who has pioneered a whole new field of research." Some reports said that he "may become the youngest Nobel Prize winner". Faced with these outside praises, Cao Yuan himself behaved very calm. In an interview, he said everyone in the project team is very smart.
No wonder only 2 years after the publication of the previous two papers, the 24-year-old genius boy returned with another 2 papers and further study results, shocking the world again. Giving him a little more time, we believe that Cao Yan may be able to change the world with his latest achievements.
