Achieve Nature and Science twins in two years ——
Recently, a Ph.D. at the University of Electronic Science and Technology of China was a bit of a fire.
His name is Yang Chao, and he published his first Science paper in late 2019 as a work, which solved the problem of quantum metal states that has been unresolved for three decades.

For a while, netizens could not help but sigh:
It could have relied on appearance, but had to rely on talent.
From the team of academician Li Yanrong
Chao Yang is a 2016 doctoral student majoring in materials science and engineering in the School of Electronic Science and Engineering, University of Electronic Science and Technology of China, whose main research direction is superconducting quantum phase transformation.
His Nature paper this year is titled "Signatures of a strange metal in a bosonic system."
It was mainly he and other researchers who first discovered and confirmed boson exotic metals in high-temperature superconductors.
Popular science time (from the official WeChat of the University of Electronic Science and Technology):
Elementary particles in the universe are divided into two types: fermions and bosons.
Fermion subsystem materials are mainly used in the electronics industry and devices, but due to high energy consumption, physical size is close to the limit and other factors, it has faced bottlenecks.
Boson devices represented by high-temperature superconductors are expected to solve these problems.
What is Exotic Metal?
Unlike ordinary metals, its resistivity is proportional to temperature, and it exists in copper-based high-temperature superconductors, which is a new state of matter with high quantum entanglement between electrons.
Thirty years ago, scientists discovered fermion exotic metals, but the existence of boson exotic metals is a long-standing scientific problem.
Internationally renowned theoretical physicist and academician of the American Academy of Sciences Chandra M. Varma commented on the discoveries of Yang Chao and others as:
A major breakthrough in condensed matter physics.
Nature reviewers called it:
Transformative results leading the development of quantum theory.
In more detail, this achievement has high theoretical value for future research on low-energy superconducting quantum computing, as well as extremely highly sensitive quantum detection technology.
Yang Chao's 2019 Science paper was titled "Intermediate bosonic metallic state in the superconductor-insulator transition."
The study is also the first time that the existence of quantum metallic states has been fully confirmed in high-temperature superconducting nanoporous films, ending more than 30 years of debate on the existence of quantum metal states and their formation mechanisms in international academic circles.
At the same time, it provides the possibility of realizing microelectronic devices in extremely low temperature working environments and the next generation of new single-photon detector devices.
This achievement has won many awards such as the "Top Ten Scientific and Technological Progress of Chinese Universities" in 2019 and the Excellent Paper Special Prize of the First Sichuan-Chongqing Science and Technology Academic Conference.
Yang Chao was also invited to Stanford University, Brown University, University of Washington and other universities for academic exchanges and public academic reports because of this achievement.
Of course, Yang Chao is not alone, behind it is the powerful team of academician Li Yanrong of the State Key Laboratory of Electronic Thin Films and Integrated Devices of the University of Electronic Science and Technology of China.
Academician Li Yanrong is also a co-author of these two papers.
Academician Li graduated from the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, won the second prize of the National Technological Invention Award in 2003 and 2007, and published more than 290 PAPERS included in SCI.
He is also the former president of the University of Electronic Science and Technology of China and the current president of Sichuan University.
The corresponding authors of both papers are Professor Xiong Jie.
Dr. Xiong graduated from the University of Electrical Sciences with a major in physical chemistry of materials, and has been engaged in research at the Superconductivity Center and the Center for Integrated Nanotechnology at Los Alamos National Laboratory in the United States.
My sophomore year began to be exposed to scientific research
What kind of courage does Yang Chao personally have to make such achievements?
He graduated from Shuangliu Tanghu Middle School in Sichuan Province, and according to the "Famous School Observation", Yang Chao has been exposed to scientific research since his sophomore year.
At that time, he knew little about the field of materials, but he was very interested, and his mind was full of new ideas.
Interest and curiosity drove him all the way to the present. However, he described the "marathon" of scientific research as not a flat "plastic track", but like entering the jungle to find a path to cross.
Encountering difficulties on the road, especially those that cannot be solved in the short term, the more patience and perseverance are needed.
As in his science paper, Yang Chao said that the research progress was more difficult than expected: "There are many times when I feel that what I am looking for is close at hand, but in fact it is far away. ”
It took him three years, during which time he confirmed various conjectures step by step with experiments, and pushed them back and forth 5 times to finally complete this masterpiece.
