When Xu Chuan was thinking about the mechanism and characteristics of the strongly correlated electronic system and the topological state of matter, the network had already exploded.

Not surprisingly, after he uploaded his paper on the theoretical framework of strongly correlated electronic systems to ARXIV, scholars who had kept an eye on the matter received ARXIV's prompts at the first time.

With the timely addition of server resources by the website staff, this time arxiv was able to withstand the swarming traffic.

Not only physicists, but also mathematicians, materials scientists, and even some netizens who can use ARXIV have downloaded the paper report.

Although there are not a few readers who can read this paper, this does not affect their lively discussion of this matter.

[It's out, it's out! Professor Xu's paper has been uploaded to ARXIV! 】

[Downloaded, but I can't read it at all, do you understand?] Come out and squeak, I wonder if he has solved this problem. 】

[If you can understand it, you probably are still gnawing on the paper, and probably no one will come out to answer your question.] 】

[However, according to Professor Xu's style, the paper he publicly uploaded to arxiv can basically be regarded as something that has been demonstrated, and if it is not solved to the point that it can be approved by everyone, he will not upload it.] 】

[Is this such an exaggeration, this is just an arxiv gathering ideas, not a journal.] What's more, even if it is a journal, there are times when it is retracted. Who can guarantee that their stuff will always be right? 】

[But have you ever seen what he uploaded, and did you miss it?] 】

【. 】

As soon as these words came out, there was a lot less controversy on the forums and websites.

Although professional physicists are still busy chewing on papers, they have not come out to express their opinions.

However, most people in the academic community are still relatively optimistic about whether the problem of strongly correlated electronic systems has been solved.

Without him, it was only because it was the famous Professor Xu who solved this problem and uploaded the paper.

Since his debut, almost all of his published papers have finally been resolved and confirmed.

At least until he makes a mistake, the academic community is happy to believe in the character of such a top scholar.

Of course, this does not mean that the academic community will abandon the repeated verification and review and easily accept the paper.

Whether it is for the sake of the personal reputation and morality of the examiner, or for the future of all mankind, not only the mathematical community, but also any academic person should maintain the utmost rigor in the face of any problem or conjecture that is being solved.

Aman Hotel Beijing, Summer Palace.

In his hotel room, Edward Witten was packing his bags and preparing to go to CERN for a meeting.

Although I chatted with Yang Zhenhuan for a while on the day of the seminar, I felt that what he said made sense, so I waited in China for a few more days.

But now that a week had passed, and there was still no movement on arxiv, he felt that it was almost time to go to CERN for a meeting.

After all, the problem of strong correlation electronic system is not so easy to solve, and it is not so easy to solve this problem in a few days.

Just then, there was a sharp knock on the door.

Putting down the trench coat in his hand, Witten got up and opened the door.

"Did you watch arxiv today?" Without waiting for him to speak, his old friend Deligne, who was standing at the door, asked suddenly.

Witten, who hadn't reacted yet, subconsciously shook his head and said, "Not today, what's wrong?" ”

As soon as the words fell, he seemed to remember something, and quickly asked in disbelief, "You mean?" Has he proven it? ”

Deligne nodded and said, "I just received a hint from Arxiv. ”

Hearing this, Witten's breathing suddenly became two minutes heavier, and he quickly returned to the room, and took out his notebook from the suitcase that had been packed.

Power on, wait.

Looking at the boot screen on the display, Witten couldn't help but take a deep breath, the originally short ten seconds would become especially long here.

But fortunately, there were no accidents in the middle, if this would have caused the computer to crash suddenly, he would have suffered a cerebral hemorrhage.

Smoothly connected to the Internet, Witten quickly opened the arxiv pre-printed website.

A piece of paper was impressively presented in front of his eyes.

With a quick click, he flipped through it carefully.

On the side, Deligne waited in the room for nearly half an hour before asking, "How is it?" ”

Looking at the paper on the computer monitor, Witten was silent for a while before replying: "Judging from the paper, I can't find it, at least for now, I can't find any flaws and problems, his logic is quite self-consistent." ”

"And theoretically, a way to explain strong electron correlation systems in terms of dimensions is indeed a feasible path, and I've been thinking about it these days. It's just that physics and mathematics are different, especially in a more practical field such as condensed matter physics, which often requires a lot of experimental results to demonstrate. ”

"It's like a standard model, it took decades to fill in before it became perfect."

After a pause, he continued: "Even if this is the case, it is possible for the theories of the physics world to be overturned. After all, with the development of technology, we will one day update more advanced theories to replace the Standard Model. ”

Deligne didn't expect that much, he thought for a moment and asked, "That is, for now, you are more optimistic that he has done it?" ”

Hearing this, Witten nodded and said, "If you only evaluate this paper, yes." ”

Hearing this, Deligne took a deep breath, was silent for a moment, and then sighed: "Witten, what kind of monster did you say we accepted as a student a few years ago?" ”

Professor Witten thought for a moment, shook his head, and said, "I don't know, but it's certain that he has already gone further than the two of us, whether it's mathematics or physics." ”

After a slight pause, he smiled and said, "Speaking of which, I'm glad I became his mentor with you in the first place, if I miss it, I will definitely regret it now." ”

"By the way, is he still in the hotel?"

Deligne: "It should still be there, although I haven't seen him appear in restaurants and other places in the past two days, it shouldn't be possible for him to run back to Jinling." ”

Hearing this, Witten immediately got up: "Let's go, talk to him." ”

Deligne: "You'd better print out the paper first, and then it's over, what can you talk about?" ”

Hearing this, Witten patted his head in annoyance, quickly sat back in front of the computer, and connected to the hotel's public printer.

With the papers, the two quickly rushed to the room where Xu Chuan lived.

Seeing the arrival of Deligne and Witten, Zheng Hai, who was in charge of security, didn't pay much attention to it, after all, there were many people who came to find Xu Chuan these days.

But before that, Xu Chuan confessed that unless he took the initiative to come out, no one would see him.

Although he knew the two professors, Deligne and Witten, until these two were Xu Chuan's former mentors, he stopped them outside the door.

"Professor Deligne, Professor Witten, I'm sorry, Academician Xu is studying the problem, he has explained before, unless he comes out himself, no one will be seen."

With apologies, Zheng Hai stopped the two at the door.

Deligne didn't care, he knew very well that their student's current status, no matter what country he put in, belonged to the kind that was protected.

Nodding, he spoke: "I know, but the problem has been solved, and it has been posted on arxiv today, please help contact me." ”

Hearing this, Zheng Hai was slightly surprised, did he get it done so quickly? Aren't they all saying that this is a difficult question?

But I didn't think much about it, after all, it was Academician Xu, and it was nothing to create some miracles.

Nodding, he spoke, "Then please wait a moment for the two professors." ”

As he spoke, he picked up the phone and called Xu Chuan.

If it was someone else, maybe he would have shirked it and waited for Xu Chuan to come out.

However, these two, he can't refuse, after all, they are Xu Chuan's former mentors.

In the hotel room, Xu Chuan's mobile phone, who was pondering a quantum computer, rang, and after connecting it, he quickly got up and walked to the door.

"Mentor? You haven't been back? ”

Looking at Deligne and Witten standing at the door, Xu Chuan was a little embarrassed, he really didn't expect these two people to be here.

After all, it's been almost a week.

"Originally, I was packing my luggage, but I didn't expect to wait for the last day, it's really surprising that you can solve this problem in such a short time." Witten said with a smile.

Xu Chuan smiled and said, "It's not short, in fact, I've been studying it for a long time before that." Let's sit down first, now I have time to talk. ”

On the other side, the United States.

When Xu Chuan met with the two mentors, Professor Schmuel Heath of the University of Rochester held a freshly printed copy of the material that still smelled of ink in his hand and read it carefully.

As a top professor in the field of superconducting materials, his achievements in the field of condensed matter physics are naturally also top-notch.

In particular, strongly correlated electronic systems have been widely used in the field of superconductivity.

For example, it can explain the pseudo-energy gap and charge spin separation of copper-based superconductors, use the Hubbard model or t-J model to describe the interaction of electrons, and determine the specific source of the mechanism of some superconducting materials.

Of course, although the strong correlation model has made some progress in the study of superconductor superconductivity, it still faces challenges in describing other superconducting materials and experimental phenomena.

By combining the strong correlation model with other theories, as well as using advances in computational methods and experimental techniques, future research is expected to reveal the nature of superconductivity in the strong correlation model.

Therefore, after the news of the report on the problem of strongly correlated electronic systems came out, Schmuel Hiss immediately logged on to ARXIV and paid attention to related fields.

"It is interesting to explain the strongly correlated electronic system from the dimensional space, and divide different strong electron correlated systems according to different dimensional spaces."

"Judging from the paper, this logic is quite perfectly self-consistent, but whether the specific experimental data will be included in this framework remains to be verified by experiments."

After reading the paper in his hand in its entirety, he breathed a sigh of relief and prepared to do it again.

On the side, his assistant and student saw that he had finished reading, and couldn't wait to ask, "Professor, Professor Xu, did he do it?" Can strongly correlated electronic systems really be unified? ”

Hearing the student's inquiry, Schmuel Hiss raised his head, thought for a moment, shook his head and said, "I don't know. ”

After a slight pause, he added: "To be precise, I haven't fully understood this paper yet." ”

Hearing this answer, the student looked confused, what is the situation?

You must know that his professor has the title of the father of superconductivity in the United States, and his research on condensed matter and strongly correlated electronic systems is definitely the top.

Even a paper that he can't read, can anyone prove that Professor Xu's stuff is right?

Looking at the astonishment and surprise on the student's face, Schmuel Hiss knew what he was thinking, smiled, and said, "This is not a complete field of physics, in this paper, there are more mathematical methods involved. And I don't have a deep understanding of mathematics. So it takes a while to understand. ”

With a remark, he lowered his head and flipped through it again.

Reading it once was not enough for him to fully comprehend this brilliant paper.

However, when he read the paper, he always felt that there were some places in this article that were unusually familiar, as if he had seen it somewhere.

Puzzled, he read it several times in a row, until the paper did not know how many times he turned to the report in the field of superconducting materials, and Professor Schmuel Hiss stared at a formula on the article and suddenly understood where the familiarity came from.

KL-66 material!

A few months ago, the same person who wrote the unified framework for strongly correlated electronic systems also wrote a research paper on the magnetic levitation mechanism of the KL-66 material in South Korea.

Nearly all researchers in the field of materials have seen the paper, and it has succeeded in directly knocking South Korea's KL-66 material back from room-temperature superconductors to conventional materials, ending a dispute that could have lasted two or three months or more.

As one of the founders of high-temperature superconducting materials, he naturally read that paper and left a deep impression on him at that time.

In addition to proving that the magnetic levitation effect of KL-66 material does not originate from the superconducting mechanism, in that paper, it is clear that the author is hiding something.

Later, he thought about it and never understood what Professor Xu was hiding, and it was not until today, after seeing this paper on the unified framework of strongly correlated electronic systems, that he understood what was hidden in that paper.

"I see, from that time, he was aware of the path and direction behind the strong diamagnetic mechanism of KL-66 material."

Muttering to himself, Schmuel Hiss sighed and shook his head.

Suddenly, he remembered something again, and the whole person was stunned for a moment.

If he remembers correctly, it seems that it has only been four or five months since the KL-66 material, right?

In four or five months, it took a little too much to find a unified framework for the strongly correlated electronic system through the strong diamagnetic mechanism of KL-66 material?

Thinking about it, he couldn't help but swallow his saliva. To be honest, this speculation really scared him a bit.

He preferred to believe that the one had been studying it for a long time before this, rather than just four or five months of breakthroughs.

After all, strongly correlated electronic systems have always been the forefront and hottest research direction of condensed matter physics, and they are not an unpopular field.

It's been decades, and no one has broken through, and he did it in four or five months, which is really a bit too scary.
