Chapter 644 Essays That Changed the Research Landscape

Historically, computational physics was the first application of computers.

Computational physics is also considered a branch of computational science.

However, the essence of computational physics is still a discipline that studies how to use numerical methods to analyze quantifiable physical problems.

This is the fundamental reason why Professor Friedman praised Chen Zhou for his talent in computational physics.

Computational chemistry is a branch of theoretical chemistry.

Sometimes, the term computational chemistry is also used to indicate the intersection of computer science and chemistry.

But its essence is the same as computational physics.

The main purpose is to use effective mathematical approximation and computer programs to calculate the total energy, dipole moment, quadrupole moment, reactivity and other properties of molecules.

Computational chemistry is also used to explain some specific chemical problems.

Computational materials science is a rapidly developing new discipline, which refers to the interdisciplinary of materials science and computer science.

Because computational materials science is a subject of computer simulation and design of material composition, structure, performance, and service performance, it is also called "computer experiment" in material science research.

It is worth mentioning that the disciplines involved in computational materials science include materials, physics, computer science, mathematics, chemistry and other disciplines.

But in essence, whether it is computational physics, computational chemistry, or computational materials science.

The nature of their disciplines is inseparable from computing.

Calculation is mathematics.

In a sense, computer science can also be summed up in mathematics.

The result of Chen Zhou's current breakthrough project is to return the essential meaning of mathematics to computational physics, computational chemistry and computational materials science.

Chen Zhou started from the research route of DMD-2 material, combined with the previous research on DMD-1 material, to explore computational materials science, which can play a greater role in it.

Then, jump out of the research category of computational materials science, and start to corroborate the research content of computational physics involved in the previous physics topics with the research content of the field of computational materials science, so as to obtain more information on this topic result.

And then, computational chemistry.

Although the research on the DMD-2 material also belongs to the category of chemical topics.

However, it is not pure enough.

Therefore, Chen Zhou has spent quite a long time perfecting the substitution of computational chemistry.

In addition to the necessary large amount of literature, Chen Zhou even found some for himself, which are very suitable for research topics using computational chemistry methods, and started to practice.

However, the subject that Chen Zhou wants to solve is a bit too "big".

This "big" does not specifically refer to the difficulty of the subject, or anything else.

The main reason is that Chen Zhou aims to solve the "unimportant" content that is easily overlooked when finding valuable research content in theoretical research, thus missing valuable research content.

This also caused the factors he needed to consider to be too "big".

Although he was not wrong in his initial thinking, numbers and symbols, or mathematics, is an absolutely trustworthy subject.

However, how to implement this idea into actual research.

Especially with this idea, computational physics, computational chemistry and computational materials science are connected in series.

becomes very difficult.

The thorny problem that Chen Zhou encountered was that after the research of computational physics, computational materials science, and computational chemistry was confirmed, he could no longer jump out of the separate discipline circle and combine them together.

Even though he has reached a certain depth in computational materials science, computational physics, and computational chemistry.

The results obtained are also astonishing.

Even if he is also mutually corroborated in the research of different computing disciplines, he has achieved good results.

But he's still going one step further, trying to create new research methods that integrate multiple computing disciplines to address his ideas.

Came across this tricky conundrum.

Although Chen Zhou also tried many ways, and combined with the feedback from the wrong question set, he tried to solve this problem.

But he just couldn't grasp the core solution point.

So that, as time passed, the time point he set was approaching step by step.

Chen Zhou also became a little irritable.

This is also the reason why Chen Zhou went out for a walk.

An impetuous mentality is no longer suitable for research.

However, Chen Zhou would never have thought of it.

Someone threw a stone into the nameless lake, and it woke him up!

It made his thoughts, like those circles of ripples, completely open.

This is not just a metaphor.

Rather, the solution Chen Zhou thought of was indeed like ripples in circles.

From surface to point, from outside to inside.

Start with every ripple in computational materials science, and with every ripple in computational physics and computational chemistry.

Chen Zhou went to look for the stone that caused the ripples, which is their core essence.

Because their core essence is the same.

That is, mathematics.

However, because of the different research content, starting from the essential point, every subsequent ripple has changed.

But now, Chen Zhou is like peeling an onion, round by round, peeling off the different ripples, and finding the heart of the onion.

In the end, Chen Zhou got the result he wanted!
He successfully combined theoretical research with mathematical methods!
Through accurate quantification of subject issues, those "unimportant" contents can not be ignored.

The results of this theoretical research should actually be called a research idea.

It is no exaggeration to say that through this research achievement, Chen Zhou has successfully pushed the research depth of computing disciplines such as computational physics, computational chemistry and computational materials to a new level.

It also excavates the greatest value of computing disciplines such as computational physics, computational chemistry and computational materials science.

This theoretical research result is called "quantitative calculation method" by Chen Zhou.

It corresponds to the "distribution deconstruction method" he named before...

On the desk, a stack of draft papers had been sorted out by Chen Zhou.

A smile finally appeared on Chen Zhou's tired face.

Raising his hand to check the time, Chen Zhou said with satisfaction: "That's right, it's just in time for July 7th, and the research content of the original plan has been completed. It's 8 days faster than the estimated time. Kuo, Kuo So, it's very nice..."

As for the thesis after the research results come out, Chen Zhou is not in a hurry at all.

Even if he continues to work abroad, these 4 days are enough to get it done.

What's more, when did his hand speed slow down?

Next, all the time up to the 25th is almost entirely belonged to the problem of gauge field theory and Yang-Mills gauge field existence and mass interval assumptions.

Thinking of this, Chen Zhou stretched suddenly.

He was indeed very tired after this intense study.

Taking advantage of the gap between solving the subject of quantitative calculation method, he had to make some adjustments and take a good rest.

Immediately, Chen Zhou turned off the computer, got up and left the chair.

After washing up, Chen Zhou, who was lying on the bed, fell asleep with a rare sense of relief these days.

July 7th was the third day since Chen Zhou worked on the quantitative calculation method.

During these three days, Chen Zhou devoted 3 hours a day to the paper on the quantitative calculation method.

Chen Zhou actually didn't want to spend so much time at first.

But when he really started to build the skeleton of the thesis, he found that this thing still seemed to have that characteristic.

That is, big!

The scope of content involved is large enough.

The depth of the content is large enough.

The value of research results is large enough.

The content to be written in the paper is also "big" enough.

No way, correspondingly, he must also give enough "big" time to complete this thesis.

Finally, three days, a complete 9 hours.

Chen Zhou completed the thesis titled "On the Practicability of Quantitative Calculation Method in Subject Research".

After completing the thesis, Chen Zhou started to encounter difficulties when submitting the thesis.

Because he doesn't know which journal to choose, it is more appropriate.

The contents of this paper include both physics, chemistry, materials science and mathematics.

It can be said that it is the result of interdisciplinary research.

After PASS lost the journal he often contributed to, Chen Zhou finally chose "Science".

This is published by the American Association for the Advancement of Science and is one of the most authoritative academic journals in the world.

As for his troubles, leave it to the academic editors of science.

According to the requirements of the journal's official website, Chen Zhou opened the preprint website e-Print arXiv after finishing the submission of the paper.

It is customary to upload this paper on the quantitative calculation method to the website.

However, when choosing a category, Chen Zhou didn't think too much, and chose the category of chemical materials science.

After all, the origin of this research result is also because of the DMD-2 material, the product of this chemistry and materials science project.

After finishing all this, Chen Zhou quit the preprint website e-Print arXiv, and closed the browser.

Looking at the time, it was only 4:[-] in the afternoon, which was still early.

Chen Zhou immediately took the research data on the Yang-Mills gauge field existence and mass interval hypothesis, and put it into it.

I don't know if it's because of the research results of the quantitative calculation method that made Chen Zhou feel a little more relaxed.

When he was studying the existence of the Yang-Mills gauge field and the assumption of mass intervals, he found that his research efficiency seemed to be higher.

After careful comparison, Chen Zhou feels that the current research efficiency is much higher than when he was trapped in the research topic of quantitative calculation method.

How should I put it, mood is something that sometimes affects efficiency.

The next day, November 7.

This is the time node set by Chen Zhou in the research plan.

On this day, Chen Zhou just took a pen lightly on the research plan, and under this time node, he ticked off.

Then, he put the research plan aside.

Chen Zhou's excitement had already been experienced when he completed the quantitative calculation method.

Now, he just confirms lightly that he has completed the expected plan.

Beyond this time node, Chen Zhou was completely immersed in the research of gauge field theory and Yang-Mills gauge field existence and mass interval assumptions.

With the deepening of research, Chen Zhou encountered more and more problems.

But as the problem was solved, Chen Zhou also found that the dawn was getting closer and closer to him.

The feedback on this topic is not like the topic of quantitative calculation method.

That topic is almost without the shoulders of giants, and Chen Zhou can stand on it.

But for this subject, Chen Zhou has already stood on the shoulders of giants and seen the distant scenery.

He just needs to take his own step in reaching the landscape.

Of course, this step is far bigger than the steps taken by all the previous giants.

However, it is not that simple to take this huge step.

"Most extraordinary, that is, four-dimensional quantum field theories with interactions that we know are effective field theories with truncated energy scales. Since the beta-functions of most models are positive, it seems that most of these models have a Landau pole, Because we don't know at all whether they have extraordinary ultraviolet fixed points..."

"Therefore, if such a quantum field theory is defined on every scale, it can only be regarded as a pure free field theory. However, the Yang-Mills theory with non-commutative structure groups is an exception, and it has a property called Asymptotically free, which means it has a simple ultraviolet fixed point..."

"Thus, it can be hoped that it will become an extraordinary quantum field model of constructive thinking..."

"The color confinement of the Yang-Mills theory of the non-commutative group has been proved in line with the rigor of theoretical physics, but there is no proof in line with the rigor of mathematical physics..."

Chen Zhou recalled this paragraph, written by Arthur Jaffe and Edward Witten, the description of the official statement of the Yang-Mills gauge field existence and mass interval assumptions.

In fact, beyond the QCD scale, strictly speaking one is called the confinement scale.

After passing the confinement scale, those color-charge particles are connected by the “flow tube” of color dynamics, so there is a linear potential between the particles.

Also based on this, when Arthur Jaffe and Edward Witten described this part of the content, they also believed that free charged particles such as gluons could not exist.

Because, without these confinement effects, the zero-mass gluon can be seen.

But because they are confined, they can only see the bound state of gluon without color charge, that is, the glue wave.

From this, it also shows that the rubber wave has quality.

Therefore, the problem of mass gap is drawn, that is, the mass gap assumption.

Thinking of this, Chen Zhou lowered his head slightly, and glanced at the draft paper in front of him.

For Chen Zhou, who has already solved the color-closed problem on the rubber ball problem, he is actually holding the key to unlocking the problem of mass interval assumptions.

Now, it depends on how he uses this key.

Chen Zhou also felt for the first time that the feeling of standing on his shoulders is actually more comfortable...

Just when Chen Zhou was immersed in the subject research, he submitted a paper to "Science", which has already been published.

In fact, the paper circulated from the preprint website e-Print arXiv long before it was published in Science.

Even though "Science" is a weekly magazine with a total of 51 issues throughout the year.

Its publishing efficiency has not caught up with the attention paid to Chen Zhou by the academic circles.

However, compared with the authoritative top academic journal "Science", the influence of the preprint website e-Print arXiv is still a little bit worse.

After the publication of "Science", the hot discussion out of the circle is enough to prove this point.

The reason why "Science" was out of the circle was because when Chen Zhou's paper was published, their evaluation was——
