Chapter 478 What Kind of Monster Did We Accept as a Student?
While Xu Chuan was thinking about the mechanism and characteristics of the generation of strongly correlated electron systems and topological states, the Internet was already in an uproar.
As expected, after he uploaded the paper on the theoretical framework of strongly correlated electron systems to arxiv, scholars who kept paying attention to this matter received arxiv's prompts at the first time.
With the website staff adding server resources in a timely manner, arxiv was able to withstand the influx of traffic this time.
Not only physicists, but also mathematicians, material scientists and even some netizens who use arxiv have downloaded this paper report.
Although only one in a hundred readers can understand this paper, this does not affect their heated discussion of this matter.
[It's out! Professor Xu's paper has been uploaded to arxiv! ]
[Downloaded, but I can't understand it at all. Does anyone understand it? Come out and say something. I just want to know if he has solved this problem. ]
[Those who can understand it are probably still reading the paper now. Probably no one will come out to answer your question. 】
【However, according to Professor Xu's style, the papers he publicly uploaded to arxiv can basically be regarded as things that have been proven. If he has not solved it to the point where everyone can agree, he will not upload it. 】
【Is it so exaggerated? This is just an arxiv that gathers ideas, not a journal. What's more, even if it is a journal, there will be times when the paper is retracted. Who can guarantee that their things are always right? 】
【But have you ever seen anything he uploaded that was wrong? 】
【.】
As soon as this was said, the debates on the forums and websites suddenly decreased a lot.
Although professional physicists are still busy working on papers and have not come out to express their opinions.
But most people in the academic community are still relatively optimistic about whether the problem of strongly correlated electron systems has been solved.
No other reason, just because the one who solved this problem and uploaded the paper was the famous Professor Xu.
Since his debut, almost all of his published papers have been solved and confirmed.
At least before he made a mistake, the academic community was still willing to believe in the character of such a top scholar.
Of course, this does not mean that the academic community will abandon repeated verification and review and easily accept this paper.
Whether it is for the personal reputation and morality of the reviewer or for the future of all mankind, not only the mathematical community, but any academic community should maintain the most rigorous attitude to face any problem or conjecture that is being solved.
Beijing, Yihe Aman Hotel.
In the hotel room, Edward Witten was packing his luggage and preparing to go to CERN for a meeting.
Although he talked with Yang Zhenning for a while on the day of the seminar, he felt that what he said made sense and waited for a few more days in China.
But now a week has passed, and there is still no movement on arxiv. He thinks it is almost time to go to CERN for a meeting.
After all, the problem of strongly correlated electron system is not so easy to solve. It is not so easy to solve this problem in a few days.
At this moment, there was a hurried knock on the door.
Putting down the windbreaker in his hand, Witten got up and opened the door.
"Have you read arxiv today?" Before he could speak, his old friend Deligne, who was standing at the door, asked suddenly.
Witten, who hadn't reacted yet, shook his head subconsciously and said, "Not today, what's wrong?"
As soon as he finished speaking, he seemed to remember something and asked quickly in disbelief, "You mean? He has proved it?"
Deligne nodded and said, "I just received a reminder from arxiv."
Hearing this, Witten's breathing suddenly became heavier. He quickly returned to the room and took out his notebook from the packed suitcase.
Turn on the computer and wait.
Looking at the boot screen on the display, Witten couldn't help but take a deep breath. The short ten seconds became particularly long at this moment.
But fortunately, there was no unexpected situation in the middle. If the computer suddenly crashed at this moment, he would really have a cerebral hemorrhage.
Successfully connected to the network, Witten quickly opened the arxiv preprint website.
A paper appeared in front of him.
Quickly clicked it and he read 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 screen, Witten was silent for a while before replying, "From the paper, I can't find any flaws or problems, at least for now. His logic is quite self-consistent."
"And theoretically, the way to explain the strong electron correlation system from the dimension is indeed a feasible way. I have been thinking about it these days. It's just that physics and mathematics are different, especially in the more practical field of condensed matter physics, which often requires a lot of experimental results to prove."
"Just like the standard model, it took decades to fill in before it gradually became perfect."
After a pause, he continued, "Even so, the theory of physics may be overturned. After all, with the development of science and technology, we will one day update more advanced theories to replace the standard model."
Deligne didn't think so much. He thought for a while and asked, "That is to say, for now, you are more optimistic that he has done it?"
Hearing this, Witten nodded and said, "If I only evaluate this paper, yes."
Hearing this, Deligne took a deep breath, was silent for a while, and then sighed: "Witten, what kind of monster did we accept as a student a few years ago?"
Professor Witten thought about it, shook his head and said, "I don't know, but what is certain is that he has already gone further than the two of us, whether it is mathematics or physics."
After a slight pause, he smiled and said, "Speaking of which, I am glad that I became his mentor with you. If I missed it, I would definitely regret it now."
"By the way, is he still in the hotel now?"
Deligne: "He should still be there. Although I haven't seen him appear in the restaurant and other places these two days, he should not be able to run back to Jinling."
Hearing this, Witten immediately stood up: "Let's go and talk to him."
Deligne: "You should print out the paper first. If you go there like this, what can you talk about?"
Hearing this, Witten slapped his head in annoyance, quickly sat back in front of the computer, and connected to the hotel's public printer.
With the paper, 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, did not care too much, after all, many people came to see Xu Chuan these days.
But before that, Xu Chuan explained that unless he took the initiative to come out, he would not see anyone.
Although he knew Professors Deligne and Witten, and knew that they were Xu Chuan's former mentors, he still stopped them at the door.
"Professor Deligne, Professor Witten, I'm sorry, Academician Xu is studying the problem. He has explained before that unless he comes out, he will not see anyone."
With an apology, Zheng Hai stopped the two at the door.
Deligne didn't care either. He knew very well the current status of their student. No matter which country he was placed in, he was protected.
Nodding, he said: "I know, but the problem has been solved. It has been posted on arxiv today. Please help contact him."
Hearing this, Zheng Hai was slightly surprised. Didn't it get done so quickly? Didn't everyone say that this problem was difficult?
But he didn't think much about it. After all, he was Academician Xu, and creating a miracle was nothing.
He nodded and said, "Then please wait for a moment, professors."
Then he picked up the phone and called Xu Chuan.
If it were anyone else, he might refuse and wait for Xu Chuan to come out.
But he couldn't refuse these two, after all, they were Xu Chuan's former mentors.
In the hotel room, Xu Chuan's cell phone rang while he was thinking about quantum computers. After answering the call, he quickly got up and walked to the door.
"Mentor? You haven't been back yet?"
Looking at Deligne and Witten standing at the door, Xu Chuan was a little embarrassed. He didn't expect that these two people were still here.
After all, it's been almost a week.
"I was packing my luggage, but I didn't expect to wait until 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 have been studying it for a long time before this. Come in and sit down first. Now I have time to talk slowly."
On the other side, the United States.
When Xu Chuan met with his two mentors, Professor Shmuel Heath of the University of Rochester was holding a freshly printed document that still smelled of ink and reading it carefully.
As a top professor in the field of superconducting materials, his achievements in the field of condensed matter physics are naturally top-notch.
In particular, the strongly correlated electron system has 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, determine the specific source of the mechanism of some superconducting materials, and so on.
Of course, although the strongly correlated model has made some progress in the study of superconducting phenomena in superconductors, it still faces challenges in describing other superconducting materials and experimental phenomena.
By combining the strongly correlated model with other theories and taking advantage of the progress of computational methods and experimental techniques, future research is expected to reveal the essence of superconducting phenomena in the strongly correlated model.
So after the news of the report on the problem of the strongly correlated electron system came out, Shmuel Heath logged on to arxiv as soon as possible and paid attention to related fields.
"It's interesting to explain the strongly correlated electron system from the perspective of dimensional space and to divide different strongly correlated electron systems according to different dimensional spaces."
"From the paper, the logic is quite perfect and self-consistent, but the specific experimental data and whether they will be included in this framework need to be verified by experiments in the future."
After reading the paper in his hand carefully, he breathed a sigh of relief and prepared to read it again.
On the side, his assistant and student saw that he had finished reading it, and asked impatiently: "Professor, did Professor Xu do it? Can the strongly correlated electron system really be unified?"
Hearing the student's question, Shmuel Heath raised his head, thought for a while, 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 was confused. What's going on?
You should know that his professor is known as the father of superconductivity in the United States. His research in condensed matter and strongly correlated electronic systems is absolutely top-notch.
Even he couldn't understand the paper. Who could prove whether Professor Xu's work was correct?
Looking at the astonishment and surprise on the student's face, Shmuel Heath knew what he was thinking. He smiled and said, "This is not a complete physics field. In this paper, there are more mathematical methods involved. And I am not deeply involved in mathematics. So it takes some time to understand."
After adding a sentence, he lowered his head and read it again.
Reading it once was not enough for him to fully understand this exquisite paper.
However, when reading the paper, he always felt that some parts of this article were unusually familiar, as if he had seen it somewhere.
With doubts, he read it several times in a row. Until he turned to the report on the field of superconducting materials for the nth time in the paper, Professor Shmuel Heath stared at a formula in the article and suddenly understood where the familiarity came from.
KL-66 material!
A few months ago, the person who wrote this unified framework of strongly correlated electron systems also wrote a research paper on the magnetic levitation mechanism of South Korea's KL-66 material.
Almost all researchers in the field of materials have read that paper, and it has successfully directly knocked South Korea's KL-66 material back from a room-temperature superconductor to a conventional material, ending a dispute that might have lasted for two or three months or even longer.
As one of the founders of high-temperature superconducting materials, he naturally read that paper, which left a very deep impression on him at the time.
In addition to proving that the magnetic levitation effect of KL-66 materials does not come from the superconducting mechanism, in that paper, he clearly felt that the author had hidden something.
Later, he thought about it and didn't figure out what Professor Xu had hidden until today, after reading this paper on the unified framework of strongly correlated electron systems, he understood what was hidden in that paper.
"So that's it, he realized the path and direction behind the strong anti-magnetic mechanism of KL-66 materials from that time."
Muttering to himself, Shmuel Heath sighed and shook his head.
Suddenly, he remembered something and was stunned for a moment.
If he remembered correctly, it seemed that it had only been four or five months since the KL-66 material was discovered?
In four or five months, through the strong anti-magnetic mechanism of the KL-66 material, a unified framework leading to a strongly correlated electron system was found. Isn't this a bit too abnormal? ?
Thinking about it, he couldn't help swallowing his saliva. To be honest, this guess really scared him a little.
He would rather believe that the person had been studying for a long time before this, rather than a breakthrough in just four or five months.
After all, the strongly correlated electron system has always been the most cutting-edge and hottest research direction in condensed matter physics, and it is not an unpopular field.
For decades, no one has made a breakthrough, and he got it done in four or five months, which is really a bit too scary.
