Research starts with PhD students

Chapter 118 Three papers, invitation from CP group! Yu Fei: We all listen to you!
Although he had decided to study the fermion Hubbard model, Zhang Shuo did not rush to start the research, but continued to organize the paper on numerical simulation of the NS equations.

There is a lot of research content in the numerical simulation of the NS equations, and it is a heavy task to write the manuscripts and organize the contents on the computer.

All the contents are divided into three parts, two of which are the calculation and analysis methods of NS equations.

One is the computational simulation content.

Each one is an independent study and there is nothing wrong with publishing them separately.

After thinking for a while, Zhang Shuo decided to submit the two computational analysis papers separately to Advances in Mathematics and the computational simulation content to the Journal of the American Mathematical Society.

Regarding my previous research on the Gerbov conjecture, Advances in Mathematics sent me a special message to invite me to contribute to the paper. They also sent me several more messages afterwards, meaning that they wanted to maintain a good relationship and hoped that Advances in Mathematics would be given priority for future papers.

Zhang Shuo decided to submit two more papers.

The last time I published two papers on general algorithms, one was methodology and the other was applied research on general algorithms for elliptic equations.

Now I am publishing two articles in a row, which can be regarded as taking care of the academic journal with which I have a good relationship.

I submitted a computational simulation paper to the Journal of the American Mathematical Society purely to complete the "four major journal grand slam".

The 'Four Major Magazines Grand Slam' is not an honorary achievement, but it feels very good to be able to achieve it.

After considering the submission issue, Zhang Shuo first put the paper on the pre-release platform, and then submitted it to "Recent Advances in Mathematics" and "Journal of the American Mathematical Society" respectively.

After completing the submission, I breathed a sigh of relief, "I'm finally done!"

I spent more than half a month organizing the manuscript and the content of the paper, and I can finally breathe a sigh of relief after completing the submission.

Zhang Shuo stretched himself and walked out of the office to take a walk outside.

When I got to the first floor, I saw Tan Youming and Wang Hui standing together chatting.

"Zhang Shuo!"

Tan Youming called out, "I see you've been sorting out the manuscripts. Are you done?"

"Just finished."

Zhang Shuo replied, then sighed, "There's too much content, more than 100 pages in total, and I divided it into three parts."

"Do you want to submit three papers?" Wang Hui asked doubtfully.

"Correct."

"Where should I submit? The research on numerical methods of NS equations should be suitable for applied mathematics, right?" Wang Hui thought and gave a suggestion, "Journal of Applied Mathematics is not bad. I have submitted a paper to it. It is also a journal in Zone 2 close to Zone 1, and its influence is not bad."

“It’s already been voted in.”

Zhang Shuo said calmly, "I submitted two papers to New Advances in Mathematics and one paper to the Journal of the American Mathematical Society."

“I originally planned to submit all my papers to Advances in Mathematics, but then I thought that the only journal missing from the four major journals is the Journal of the American Mathematical Society, so I decided to submit one to that journal as a try.”

Wang Hui and Tan Youming looked at each other.

They felt that Zhang Shuo’s statement about submitting articles to the four major journals was like talking about what he had eaten today. If there was something he had never eaten before, he would try it and see how it went.

How could he say it so calmly?
Wang Hui was silent for a long time before he asked weakly, "...Can the manuscript be accepted?"

"it should be no problem?"

Zhang Shuo thought about it and shook his head, "It doesn't matter. I'm not in a hurry. If it doesn't get accepted, I'll submit it to other magazines."

His words were calm, but his confidence was evident.

Wang Hui didn't know what to say for a moment. After a long while, he finally said, "Fortunately, you have graduated!"

He had promised his doctoral students that they would receive an additional subsidy of 50,000 yuan if they submitted papers to the four major mathematics journals, but he never expected the consequences to be so serious.

If Zhang Shuo had not graduated, the Jebov conjecture he and Sun Xingli published would also be published in the Journal of Mathematics, and perhaps Luo Yongjun would come to ask for subsidies.

Now there are three more...

Three articles, an additional subsidy of 150,000?
Wang Hui glanced at Tan Youming and felt that his face was not that great.

Tan Youming didn't know what to say.

He never expected that the other party would complete the research quickly after he gave them advice on the research direction, and was preparing to publish three papers in one go, all to the four major mathematics journals.

Three articles and four major publications!

Zhang Shuo seems so confident, his research progress must be amazing, at least it has reached the level of publication, which means it has great prospects in application.

The three professors who came on behalf of the Science, Technology and Industry Bureau last time specifically talked to Zhang Shuo about the research on the NS equation. This actually shows how high the engineering application value of Zhang Shuo's research is.

Once the paper is published, we will know how much progress has been made.

Tan Youming suddenly felt that his title of "Academician" was a bit "empty".

Academic achievements cannot be directly compared, and comparisons between different disciplines are even more impossible, but at least in terms of the number of papers published in the four major journals and the value of their applications, Zhang Shuo has left him behind.

In the future, the gap will become bigger and bigger!

Tan Youming thought for a moment and said, "At the end of the year, the High Court will help you apply for a raise in your employment level, but your situation will definitely require special approval."

"We will cooperate with the school to strive for..."

That was all he could do.

Zhang Shuo was appointed as a researcher at the Institute of Advanced Mathematics, a senior professional title, on the same level as professor.

Similarly, there are levels for hiring researchers.

General researchers are at level four, and the next level is level three. There are many titles for level three researchers, such as deputy chief researcher, specially appointed researcher, etc.

Researchers at this level are academic leaders in their professional fields, have achieved certain scientific and technological results, and have a certain influence in their professional fields.

The next level up, that is, the second-level researcher, is a leading talent in the professional field. He needs to have significant achievements in the subject area and be recognized by domestic and foreign peers.

A second-level researcher may also be called a director-level researcher, a specially appointed researcher, etc.

The first-level researcher is a special position set up by the state, and the holders are generally academicians of the Academy of Sciences or the Academy of Engineering.

Those researchers who have not become academicians will be close to being evaluated as academicians as long as they can meet the first-level employment requirements.

There are many strict conditions for upgrading your employment level to a higher level if you hold a senior professional title.

For example, years of work experience.

Zhang Shuo's situation clearly does not meet the requirements.

The High Court can directly appoint him as a researcher, but if he wants to be promoted further, he needs to make a public announcement and apply for a higher level position. Applications that do not meet the requirements need to apply for special approval. …

He rested for the next few days and then began to study the fermion Hubbard model.

The mathematical model is much more complicated than the study of partial differential equations. The corresponding Hamiltonian alone is a bit of a headache. To study the computational simplification of its numerical simulation, a lot of physical expressions are needed.

This is equivalent to opening up a new direction.

Zhang Shuo is still very interested in this. For him, the new research direction is a challenging one.

Although the research is not difficult, research in new directions is always different, and the computational analysis of mathematical models involves different areas of knowledge content, so a lot of knowledge needs to be supplemented.

The research still starts with "氪币". After finding the direction, I will supplement the relevant knowledge. I can also learn a lot in the process of research.

The difficulty of the fermion Hubbard model is that it has no strict analytical solution in two and three dimensions, and the computational complexity is very high, so even supercomputers cannot perform effective numerical simulations.

However, from a mathematical point of view, if we want to simplify the computational complexity, we must start with model analysis and numerical solution.

After understanding the research direction, Zhang Shuo also discovered a problem -

Using krypton coins to purchase research progress can help him find the right direction, but it cannot increase his knowledge.

He found a lot of information about the Fermion Hubbard model. The first step was to fundamentally understand the process of how the Fermion Hubbard model describes the movement of electrons.

During the research process, he also felt that he was enriching himself.

Most of the previous research used the knowledge and methods already known in the mind, but now we absorb new knowledge to complete new research.

He was not in a hurry to complete the research quickly, but instead enjoyed the feeling of accumulating knowledge bit by bit.

……

That morning, Zhang Shuo's office welcomed three guests.

Yu Fei, Deng Yunshan, and Zhu Wang.

They are all researchers in the CP group of the Physics Center of the Institute of High Energy Physics.

Yu Fei made a special trip to Soochow University for no reason. After meeting Zhang Shuo, he talked about the experimental direction of "strong electromagnetic interference super decay".

"We still don't know much about this direction, and we want to hear your opinion."

Yu Fei said bluntly, "Last time you said it was related to an unknown physical phenomenon, but the principle is not clear, so it is difficult for us to apply for it."

Zhang Shuo asked, "Are you sure you want to conduct experiments in this direction?"

At this time, Deng Yunshan smiled bitterly and said, "We have no choice!"

Deng Yunshan is a female researcher in her early forties. She looks heroic with her short hair, but at this moment her face is full of bitterness and she looks helpless.

Zhu Wang explained, "We really have no other options. If we can't find a direction, the CP group may have to disband."

"why?"

Zhang Shuo asked doubtfully, "My research proves that there is a problem with the signal conversion method. You can do research on improving the equipment and find a new direction."

Zhu Wang shook his head and said, "We have been studying this and have already found an experimental direction. Through continuous experiments, we can find a new signal detection and analysis method."

"This is a new direction in itself, but the Physics Center won't approve it."

Zhang Shuo still didn't understand, "Why can't it be approved? Your CP group shouldn't be short of funds, right?"

"Because of Tan Zhiming!"

Yu Fei directly mentioned the name, even skipping the title of "Academician", and his tone was gnashing his teeth, "At the meeting of the Physics Center half a month ago, Tan Zhiming left the CP group and handed the mess to me."

"Tan Zhiming's algorithm project team needed funding, so we talked about this at the meeting. Later, we learned that the Computing Center had already started programming large-scale experimental deviation analysis algorithms, one stage ahead of Tan Zhiming's research."

Zhang Shuo listened and nodded. Of course he knew the progress of the computing center.

Yu Fei continued, "Tan Zhiming insisted that there was something wrong with the computing center's algorithm and wanted the computing center to make a report, but the computing center ignored him."

"He still insisted on continuing the algorithm demonstration, but research requires funding."

"It is impossible for the Institute of High Energy Physics to support two identical algorithm projects at once, and Director Wu was unable to approve the funding, so Tan Zhiming came up with the idea of ​​using the CP group's funding."

"At that time, I directly refused and had a quarrel with him."

"Later, when we applied for a new direction, we got stuck. He was in charge of the Science and Technology Planning Department, and we couldn't even get a project approved."

"He refused on the grounds that our research had no theoretical support, no sound design, and no certainty that the experiment would be fruitful."

Of course.

The research on signal detection and analysis methods definitely requires repeated experimental accumulation.

After Yu Fei finished speaking, he said to Zhang Shuo, "So, we have another purpose for coming here this time, which is to invite you, Professor Zhang, to join the CP group."

"I join?"

Zhang Shuo didn't expect the other party to make this invitation.

"Correct."

Yu Fei nodded affirmatively, "Professor Zhang, you are also interested in this research, right?"

"If you join the CP group and set a research direction, whether it is strong electromagnetic interference hyperon decay or new signal conversion methods, you will get support from many people."

"When the time comes, we will use our own funds for research, and no one can say anything."

"Your prestige is very high in the Institute of High Energy Physics, including the Physics Experiment Group and the Computing Center."

Yu Fei said very frankly, "You join the CP group as a specially appointed consultant, and your level is equal to mine. You lead the research direction, and no matter what research you do, we will listen to you."

Deng Yunshan and Zhu Wang also advised, "Yes, we will listen to you."

"Professor Zhang, you should come to the CP group. Being a specially-appointed consultant only guides the research direction. You don't need to work in the experimental base for a long time."

"Whatever the research is, we agree with it. Once you join, no one else will have anything to say."

This invitation was somewhat sudden.

Zhang Shuo took a big sip of coffee to calm himself down. After a moment of silence, he said, "I can't make a decision on this matter right away."

"Well, let me think about it."

"About a week. I'll give you an answer within a week."
