Great Country Academician

Now that he decided to go slowly, Xu Chuan put down his research and stopped after sorting out the research results of KL-66 material.

After a complete and detailed mathematical mechanism explanation has been made, the remaining work is to convert it into a mathematical model, and then deduce it through the model to determine what needs to be done in order to make the strong diamagnetic mechanism of the KL-66 material applied to other superconducting materials.

This is a process that requires constant experimentation, and it takes a long time, but relatively speaking, there are not many problems. As long as you continue to go through calculations and experiments, you can always lock the final suitable method.

For computational materials science, this is where mathematics is most powerful.

After the development of computational materials science to a certain extent, a series of processes from raw materials to finished materials can be directly simulated through a series of mathematical methods and models.

The most difficult part is to use mathematics to find suitable mechanisms and models.

But now he has taken care of the most difficult part, and the rest can be handed over to Chuanhai Materials Research Institute.

The calculation model owned by Chuanhai Material Research Institute has been quite powerful after years of continuous improvement.

The next day, early in the morning, after waking up, washing up and having breakfast, Xu Chuan habitually walked to the study, preparing to continue his research. When he reached the door, he suddenly stopped, remembering that he had decided yesterday to postpone his research.

Shaking his head with a dumbfounded smile, he turned around and went back to the bedroom to change his clothes before heading to Nantah University.

I haven't returned to school for more than half a month, and I don't know what happened to the four newly recruited students.

Oh, by the way, and that assistant thing.

Suddenly, a memory flashed across Xu Chuan's mind. No wonder he always felt as if he had forgotten something before. It turned out that there was another thing hanging here.

It should have been dealt with before going to the capital for a meeting, but now that it has been so long, I guess the school is in a hurry.

Walk through the teaching building and all the way to your office.

Pushing open the door, among the five students, only Ding Rui and Rong Xinji were in the office, and the other three might have gone to class or were busy with other things.

Xu Chuan didn't care either. After all, at the stage of postgraduate and doctoral students, learning basically depends on self-consciousness.

On the contrary, the two newly recruited students turned their heads to look over after hearing the movement, and after finding out that it was their tutor, they shouted with some surprise and surprise: "Professor, you are back!"

They haven't seen each other for more than half a month. For them, this is simply a new historical record since their study career.

After all, they had never been unable to see their mentor for more than half a month before.

But according to senior brother Cai Peng, it's only half a month, it's not a big deal.

Xu Chuan nodded, and responded: "Well, how did you read the textbooks I gave you earlier?"

"Another point."

"It's almost over."

The two students answered with different words, but the meaning was the same. Xu Chuan nodded, sat down and turned on the computer, ready to enroll his course.

In the office, Rong Xinji raised his head, glanced curiously at the tutor who was busy with his own affairs, and the words of Senior Brother Cai appeared in his mind.

"If you can see the mentor in the office, either he has solved the problems he encountered, or he has no research in his hands."

Thinking about the problem he had seen more than half a month ago, he swallowed, and asked nervously and expectantly: "Professor, the problem of the strongly correlated electron system you studied last time has been solved. ?”

Although the calculation formula on the manuscript paper he saw by chance last time made him, an IMO gold medalist and a graduate student in mathematics, feel desperate.

But he is not someone who gives up so easily.

Moreover, he also wanted to know how far the distance between himself and his mentor was.

So after class, he searched the Internet for information about the associated electronic system. Although the information collected was quite detailed, he was not a physics student, so he was not very clear about the ultimate difficulty of this problem.

It wasn't until later, when he was taking a minor class, that he asked a professor from the Academy of Physics, that he understood the significance of the strongly correlated electron system problem to condensed matter physics.

If, in terms of mathematics, the seven millennium problems are the most prominent seven peaks, then the number theory direction he studied is probably the most famous Riemann conjecture.

The position of the strongly correlated electron system problem in the condensed matter physics system is not weaker than the height of the Riemann conjecture in pure mathematics.

As for the difficulty, because they are two completely different systems, it is difficult to compare in terms of difficulty.

But his professor at the Academy of Physics said that the problem of strongly correlated electron systems may not be as difficult as the Riemann conjecture, but its difficulty is definitely not weaker than one of the most important in pure mathematics, the "Goldbach conjecture", and even higher.

Rong Xinji may not know much about the direction of physics, but it is very clear when it comes to the direction of mathematics he studies.

He gasped when he heard this answer.

Goldbach is the representative of additive number theory, although it was not selected into the seven millennium difficulties, but that is only because the other two conjectures related to number theory that were selected into the millennium problems involved There are more fields, and after being solved, it can promote the development of mathematics and even science to a greater extent.

Not being selected into the Millennium Problem does not mean that Goldbach's conjecture is not difficult. If it is not difficult, from 1742 to the present, nearly three hundred years ago, this conjecture has been solved long ago.

A problem of Goldbach's conjecture level made Rong Xinji instantly understand the gap between himself and this mentor.

This gap is probably not suitable to be described by billions of points.

After all, he really never thought that he would be able to solve a mathematical problem of the level of Goldbach's conjecture one day, even if he is an IMO gold medalist.

After all, IMO gold medals are not uncommon, and there have been hundreds of them in the past hundred years since it was held.

However, among these nearly a thousand people, how many can touch this kind of T1 or even T0 level problems? I can count on my fingers.

It can only be said that the degree of abnormality of his tutor, even in the entire history of mathematics, is ranked among the best.

Of course, at this meeting, Rong Xinji is more concerned about whether the problem of the strongly correlated electronic system will be solved by this mentor.

Hearing the student's curious inquiry, Xu Chuan replied without raising his head: "No, the problem of strongly correlated electronic systems can't be solved so easily."

"Then why did you go back to the office? Didn't Senior Brother Cai say that you usually only come back after solving the problem?" Rong Xinji asked bluntly.

Hearing this, Xu Chuan raised his head, glanced at the student, and said, "If you are talking about the problem I saw at my place more than half a month ago, it has indeed been solved."

The corner of Rong Xinji's mouth twitched, and he choked out a sentence: "Congratulations, Professor."

Well, Senior Brother Cai is indeed right.

He thought it was an exception for the tutor this time, after all, it is normal for a problem of this level to have no progress.

Unexpectedly, the tutor finally solved the problem before appearing.

Although I don't know how long the instructor has been studying this problem, even if it is only the last step, it is still a world-class problem.

Just like Goldbach's conjecture, even mathematicians in the country where the sun never sets proved the weak Goldbach's conjecture in 13 years, but the strong Goldbach's conjecture is still far away after nearly ten years.

It took more than half a month to solve this difficult problem. What should he say?

Stand up and call six six six?

Although he felt that the student's expression was a little weird, Xu Chuan didn't think too much about it. After reporting the matter related to the curriculum, he picked up the mobile phone on the table and called Principal Tan Shaoyuan.

After hearing that he was already at Nantah University, Principal Tan quickly hung up the phone.

After a while, he personally rushed over with the two administrative assistants he had selected earlier.

Walking into the office, Tan Shaoyuan greeted with a smile: "You can be regarded as coming out of home."

Xu Chuan smiled embarrassedly, and said, "I had some research inspiration before, and I forgot about the assistant."

Tan Shaoyuan said with a smile: "It's okay, academician Xu, your research is important, and it's nothing to wait here for a while."

After a pause, he turned around slightly, revealed the two assistants following him, and introduced: "These two assistants selected for you by the administrative side have rich work experience, Mr. Xu How about it?"

Behind them, the two assistants introduced themselves.

The one who is a little taller is named Tang Ran. His hair is tied in a simple ponytail and a strand of fringe is left, which half exposes his forehead. He looks very energetic.

The other one is slightly shorter, named Lu Ling, with a pair of round-rimmed glasses and long black hair that is straight over the shoulders. She looks quite cute.

After glancing at the assistant that Nantah had picked out for him, Xu Chuan couldn't help but glance at Principal Tan again, opened his mouth, hesitated to speak.

To be honest, he doubted whether it was true that the two assistants mentioned by the principal just now had rich work experience.

After all, judging from their appearance, these two female assistants are probably not more than twenty-five years old.

Moreover, since when did Nantah's assistant look so good?

Although he is not a face controler, it has to be said that the looks of these two female assistants are no problem at all in South University.

Of course, what Xu Chuan didn't know was that these two assistants were not actually selected from Nantah University.

Originally, Nanjing University selected two assistants, one male and one female, from the administrative side, but they were all changed later.

Noticing his gaze, Tan Shaoyuan asked with a smile: "As for the candidates, please rest assured, Academician Xu, Tang Ran and Lu Ling are both very good comrades, and they are absolutely careful, stable and reliable in their work."

Xu Chuan opened his mouth, and wanted to ask why they were all lesbians, but he held back in the end.

To be honest, whether it is a scientific research assistant or an administrative assistant, the work of an assistant is basically a hard and tiring job.

Let alone lesbians, even gay men may not be able to last long in assistant positions.

So he didn't quite understand why the two assistants the school picked for him were all girls, so it would be nice to have a boy as a coolie.
