Institute of Condensed Matter Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA.

Wen Xiaogang sat at his desk while drinking coffee while browsing the New York Times' latest report on China's electromagnetic space launch system and aerospace aircraft project.

In recent years, Sino-U.S. Trade frictions have intensified. Previously, the United States could still take advantage of its advantages in the field of science and technology. Even the technological landscape has reversed.

Nowadays, although the United States still dominates many high-precision fields, there is no strategic product like Jinlong Battery that can compete with China.

Before the Sino-US trade war, China was in a tactical offensive and strategic offensive, and the United States was in a strategic defensive and tactical offensive.

Now, the United States has no capital to tactically compete with China.

A golden dragon battery directly differentiated the western society originally led by the United States.

Even those Chinese students who come to study in the United States now have a high national pride. In the past years, the return rate of foreign students after graduation has mostly remained at 70 to 80%. Until now, the proportion of returning students has exceeded 90%. .

In a sense, American colleges and universities have become the cradle of China's top scientists and engineers, as American graduates of science and technology are declining.

In addition, universities in China are also making further efforts. Last year, Peking University sent someone to contact them. If they hadn't already joined the U.S., and taught at MIT for decades, their children and grandchildren would already be used to American life. I'm afraid Wen Xiaogang agreed early.

However, in recent days, media reports on Sino-US Jinlong battery project negotiations have gradually diminished, replaced by China's plans to launch electromagnetic orbital launch systems and air and space aircraft projects.

Of course, most of the media in the United States ridicule and think that this plan is impossible at all.

At this point, Americans have considerable confidence. As the world's leading space power, the United States has a very strong accumulation of space technology. The Apollo moon landing program, the space shuttle program ...

Even the Soviet Union during the Cold War could barely compete with the United States.

Therefore, when this plan from China reached the United States, NASA experts publicly stood up and said that Pang Xuelin was whimsical.

Human beings have not yet fully tapped the potential of chemically powered rockets, but have invested resources in so-called electromagnetic ejection space launch systems. It is simply putting the cart before the horse.

Even Wen Xiaogang himself is not optimistic about this project of Pang Xuelin. In his opinion, let alone say that the production of superconductors required for electromagnetic ejection orbits and the low temperature liquid nitrogen used to maintain superconductors requires an astronomical amount of capital. digital.

Even with China's economic strength, this plan is not possible.

Of course, if Pang Xuelin could find a real-temperature superconductor in the true sense, it would be another story.

However, as a top international condensed matter physicist, Wen Xiaogang does not think that with the current level of research on superconductors in physics, humans can find real temperature superconductors in a short period of time.

Just when Wen Xiaogang was drinking coffee, he looked at the webpage with some boredom.

Bang bang ——

The knock on the door suddenly sounded.

"Come in."

Wen Xiaogang said.

With a click, the door lock was opened.

A 60-year-old man of Chinese descent came in. He was wearing a delicate casual suit, and his hair was meticulously combed behind his head.

"Patrick, why are you here?"

Wen Xiaogang froze slightly.

Patrick Lee, Chinese name Li Yada, MIT William and Emma Rogers Professor of Physics, a leading figure in condensed matter physics, in the fields of disordered electronic systems, mesoscopic physics, condensed matter physics, low temperature micro components There are many outstanding contributions.

Li Yada was born in Xiangjiang and has long been a U.S. citizen. His qualifications at MIT are even older than Wen Xiaogang.

Both are top condensed matter physicists and are the deputy directors of the MIT Condensed Matter Physics Institute.

Li Yada said with a dignified expression, "Wen, hurry up on the arXiv preprint site."

"what's wrong?"

Wen Xiaogang froze slightly.

Li Yada said: "Just two hours ago, the super genius in China just uploaded a paper on condensed matter physics. In this paper, he used mathematical methods to solve the problem of the correlation between superconducting states and quantum fluctuations, and constructed A mathematical model of superconductors. His theory can explain not only conventional superconductors that follow the BSC theory, but even heavy fermion compounds, copper oxide superconductors, iron-based high-temperature superconductors, and even graphene two-dimensional electronic systems. Superconductors are perfectly in line with his theory, in other words, he has found the ultimate secret of superconductivity. "

"what?"

Wen Xiaogang was taken aback and looked at Li Yada incrediblely.

Li Yada said: "This is what Professor Wardessa of Princeton University just called to tell me. You should know about Wardessa's temperament, he will not talk casually."

Wen Xiaogang nodded, no longer hesitated, opened the arXiv website directly, and found Pang Xuelin's thesis.

Later, he downloaded and printed the paper, and Patrick and read it carefully.

Time passes by every minute.

One hour, two hours, three hours ...

Without knowing it, it was getting dark.

It wasn't until a harsh ringing of the phone rang that Wen Xiaogang and Li Yada were awake from meditation.

Wen Xiaogang looked at his mobile phone. It turned out that his wife called and asked him why he didn't go home for dinner.

Wen Xiaogang coped with a few words casually, and then looked at Li Yada: "Patrick. What do you think of Pang Xuelin's theory?"

Li Yada said: "It's hard to say now, but from the experimental data and theory, this set of theories is likely to solve the problem of the formation mechanism of the superbody for a century, and it is of great significance to find new superconducting materials in the future.

Wen Xiaogang nodded, pondered for a moment, and said, "Patrick, I'm going back to China."

"You go to China?"

Li Yada looked up in surprise and looked at Wen Xiaogang.

Wen Xiaogang said: "You should have read the report that China proposed to establish an electromagnetic launch space launch system and an aerospace aircraft project not long ago?"

Li Yada nodded and frowned, "You mean, Pang Xuelin suddenly uploaded this thesis, and it wasn't all about it."

Wen Xiaogang nodded: "We cannot treat Professor Pang Xuelin as an ordinary scientist. I suspect he has found a technical route to realize normal temperature superconductors in the true sense."

"It's unlikely."

Li Yada didn't dare to believe each other.

Wen Xiaogang smiled and said, "Patrick, don't forget, one of the greatest mathematicians in history and the youngest Nobel Prize winner in chemistry. Does he have fewer miracles? If this paper is nothing If there is a big problem, it is no accident. Ten or twenty years later, Pang Xuelin will have another Nobel Prize in physics. We cannot overestimate such a young man. "

Wen Xiaogang, paused, continued: "But this is not the main purpose I want to find him."

"Then why are you?"

Li Yada curious.

Wen Xiaogang said: "I have spent most of my life in the field of condensed matter physics and superconductivity. I hope that in my lifetime I can see real room temperature superconductors appear in front of my eyes. I will not let this go opportunity."

...

At the same time, similar scenes and similar conversations have taken place in major superconductor research institutions around the world.

Pang Xuelin can guess the shock this paper brought to the condensed matter physics community.

In fact, it didn't take long for his paper to be uploaded to the arXiv website, and he received numerous inquiries.

Some are from the top, some are from academia, and some are from the media.

Fortunately, he didn't know much about condensed matter physics.

Therefore, his ears were quiet for a short time.

Of course, the media's report on this paper is also full of enthusiasm, even with a variety of exaggerated titles.

"The superconducting era is coming, and the new energy revolution triggered by Jinlong Battery welcomes new help ..."

"CRRC stated that it will build a vacuum superconducting maglev train on the Beijing-Shanghai Line in the future. This project is expected to end the dominance of civil airliners in long-distance transportation ..."

"China is about to usher in a power transmission and transformation revolution. The emergence of superconductors will save China more than 20% of its energy ..."

...

Of course, while discussing superconducting materials, more people turned their attention to the project of electromagnetic ejection space launch system.

On the birthday of Pang Xuelin two days ago, he posted a Weibo on the Internet and declared that he was the promoter of this project.

Then this Weibo set off another wave of controversy online.

Even with Pang Xuelin's initiative to endorse, supporters and opponents are almost evenly matched.

Among the many objections, the most important issue is the technical difficulties of this project.

Everyone believes that a prerequisite for the electromagnetic ejection space launch system is to find room temperature superconductors. If there is no room temperature superconductor, the cost of this project will be an astronomical figure. Can it be technically successful? Whether strength can support such a super project is a question.

Because of this, after Pang Xuelin posted the Weibo, many opponents stood up and asked Pang Xuelin about this issue.

They think that Pang Xuelin is doing a good job, and pushing the technology DYJ is not good for the country.

Who would have thought that only a few days later, Pang Xuelin's hand was a dissertation and fell on the faces of many opponents.

After this paper came out, almost all major media around the world are reporting on the significance of this paper.

Top scholars in the condensed matter physics community have also spoken in succession, affirming Pang Xuelin's significant contribution in this field.

Supporters of Pang Xuelin, who were suppressed by opposition voices a few days ago, also launched counterattacks.

"Don't you think Professor Pang can't do it? Look, this is Professor Pang's answer!"

"Do you think the top executives are all stupid? If you don't have a certain degree of confidence, how can you easily decide to set up such a heavyweight project?"

"My supervisor highly valued Professor Pang's thesis and thought that he unified the many superconducting theories in the current genre and fundamentally solved the problem of the formation of superconducting mechanisms. As long as a team finds a new generation based on this thesis, Superconducting materials, then the Nobel Prize in Physics will be in the pocket of Professor Pang Xuelin. "

...

"I admit that Professor Pang is awesome, but theory is theory, and reality is reality. A complete set of theories requires a decade of time to truly generalize in reality and achieve productivity *. From the nineteenth century In the first half, Faraday discovered the law of electromagnetic induction, and it took more than half a century to start the electrical revolution for human beings. From the breakthrough of the transistor theory of the tube to the information revolution, almost half a century has passed. Even if someone really passed Professor Pang's thesis found room temperature superconductors, but can it be industrially produced? Can it be applied on a large scale? What will the price of this superconductor be? The various issues involved here are not at all within a short time. May be resolved ... "

"Hey, although I think you have some truth, I still support Professor Pang ~ lightnovelpub.net ~ Professor Pang has let us down from fame to the present? Please do n’t apply the standard of ordinary people Come to Professor Pang, will you? "

Pang Xuelin naturally will not disturb in the accident world.

At this time, he was walking along the artificial lake of Qiantang Laboratory with Li Changqing and Cao Yuan.

The core area of ​​the Qiantang Laboratory is mostly Chinese-style buildings, surrounded by traditional Chinese-style gardens. The environment is beautiful, quiet and elegant.

"Professor Li, Professor Cao, the synthesis of new superconducting materials will be handed to you, and I will be the shopkeeper."

Pang Xuelin said with a smile.

Li Changqing laughed aside: "Professor Pang, rest assured, you have helped us do this. Even the atomic structure of superconducting materials has been pointed out to us. If we can't do it again, it really is I have lived in vain for so many years. "

"Professor Li is right."

Cao Yuan nodded and smiled: "Yes, Professor Pang. Where are you going to publish the paper on arXiv?"

arXiv is just a preprinted website without formal peer review. Such a thesis has no academic value in a short time.

It is because Pang Xuelin's fame is so great that his dissertation will attract so much attention after being transmitted to arXiv.

Pang Xuelin smiled and said, "I am going to set up a brand new comprehensive academic journal in the name of Jiangcheng Institute of Advanced Studies, and use this paper to make the first shot for this journal. ="

"Establishing a New Comprehensive Journal?"

Cao Yuan and Li Lichangqing looked at each other with surprise.
