Ultimate Scholar

If the dormitory where Li Mu lived was conscious, he probably wouldn't have thought that this resident who only stayed for a few months would welcome several important figures.

And Yang Zhenning, as a top physicist who is still alive, is of course considered a big shot.

With the help of his assistant, Mr. Yang walked into Li Mu's dormitory slowly.

And Li Mu in the dormitory saw this person who often saw photos in various physics books, and shouted respectfully: "Old Yang!"

Li Mu has always paid the utmost respect to scientists who have made great contributions to the human search for truth.

Old Yang smiled at him, and stretched out his hand: "Li Mu, hello."

Li Mu quickly extended his hand and shook hands with Mr. Yang.

Although Mr. Yang needs to be supported for the time being because he went upstairs just now, his two hands are still very strong.

At least write a standard model or something, there must be no problem.

"Why do you go upstairs, I just went downstairs to see you."

Stretching out his hand, he also supported Elder Yang's other arm, sat on the chair in front of the desk, and said at the same time.

Old Yang smiled and said, "It's okay, I'll take a look at your dormitory as well."

He looked around, and finally praised: "This dormitory is pretty good, it should at least be comfortable to live in."

Li Mu nodded.

"Yes, it's quite comfortable to live here, and it's also well received by Gao Neng."

After he came to the high-energy institute, the high-energy institute naturally did not treat him badly. The treatment was very good, and all meals and travel were reimbursed, even if he ate out.

As for the dormitory building he lived in, it was relatively new. The environment in the dormitory was very good and the space was large. Even though there were nearly 10 people in the dormitory, it didn't feel cramped.

At this time, Director Wang Fang, who was also at the side, heard Li Mu's words, and said with a smile: "Li Mu is our pride, not to mention that we have come all the way to the High Energy Institute, of course we have to pay attention to these details. good."

Mr. Yang smiled and said, "That's true. No matter what you do, the first priority of scientific research is to let our researchers have a good environment."

"You can't spend your money to build a particle collider, and at the same time, you can't even spend money to improve the living conditions of researchers."

Wang Fang was taken aback, and the smile on his face disappeared, "Old Yang, you don't need to talk about this kind of thing. As the director of the High Energy Institute, I will naturally not treat our people badly."

There was a bit of cleverness between the words, which made Li Mu stunned.

Suddenly he remembered a rumor in the particle physics world.

The Institute of High Energy Physics once applied to build a large-scale particle collider called CEPC, and this large-scale particle collider is aimed at the European CERN Large Hadron Collider, and the collision energy is even higher.

But obviously, the original Large Hadron Collider cost 9 billion euros, and this stronger CEPC will only be more expensive. It is estimated that the cost will exceed 100 billion yuan, but Mr. Yang has unequivocally opposed it.

As one of the top experts in the physics world, Old Yang's objection was of course very important, so the plan was shelved.

Of course, because of this matter, the relationship between the Institute of High Energy Physics and Mr. Yang, the world's top physics expert, has deteriorated.

But today, Mr. Yang came to the High Energy Institute because he wanted to see himself.

Li Mu couldn't help having a headache, why did he get himself involved in this kind of thing?

After all, the arguments of both parties are very reasonable. If they are onlookers, they may express their opinions at will, but it is difficult for him to express his views now that he is in the midst of it.

Of course, Mr. Yang didn’t come here today to fight, he waved his hands and smiled: “Hehe, okay, Director Wang, let’s not talk too much about this kind of thing, at least I saw it in your dormitory , really good."

"Then, please give me a little room to chat with Li Mu?"

Hearing what Mr. Yang said, other people naturally stopped talking. Although Mr. Yang opposed the CEPC plan of the Institute of High Energy, most people in the Institute of High Energy still have mixed feelings for Mr. Yang, at least they still have respect.

After all, when they were young, they all listened to Mr. Yang's achievements, read his papers, learned the law of parity violation and the Yang-Mills equation, and gradually grew into a master.

Just like that, everyone left the dormitory, and Mr. Yang's assistant wanted to stay here and continue to take care of him, but Mr. Yang just smiled and waved his hands, saying, "With Li Mu here, you don't have to worry about it."

When Zhu Zhu heard this, he had no choice but to nod. Of course, before leaving, he still told Li Mu a few words.

Finally, there were only two people left in the dormitory, one old and one young.

Elder Yang was not in a hurry to speak, he just turned his gaze to the draft papers on Li Mu's desk.

Soon his eyes lit up, and he picked up a few draft papers and read them.

"Is this... you're working on the Standard Model?"

he said in surprise.

"Yes."

Li Mu nodded.

Elder Yang nodded slightly, looked carefully, and did not speak.

A real scholar is like this, no matter how many things he wants to say, once he sees something academic, he will immediately turn his attention to it.

Li Mu didn't speak either, quietly waiting for Mr. Yang to finish watching.

There were a lot of draft papers, and he put them all in order, so it was very convenient for Mr. Yang to read them.

Soon, Elder Yang was quite surprised and said, "Are you trying to solve the perturbation expansion problem of the Standard Model?"

Hearing what Mr. Yang said, Li Mu couldn't help but sigh with emotion, as expected of a top physicist, he could see the intention in these few draft papers so quickly.

Then, he nodded and said, "Yes."

Mr. Yang nodded slightly, and said, "The non-perturbative definition of the Standard Model has plagued the physics community for decades—strictly speaking, it has been troubled since the Standard Model was born."

"Scholars who dare to attack this issue are either geniuses or they are beyond their capabilities."

"but……"

Elder Yang glanced at Li Mu's draft paper again, and then said with a smile, "Obviously you are a genius."

"Your research progress seems to have entered a critical stage."

"However, now it seems that you have encountered any problems?"

Li Mu nodded and said, "It's the problems encountered in the process of dealing with weak interaction forces and model coordination."

"Because of the existence of chiral fermions, when using lattice theory to realize its non-perturbative definition, the problems caused by the No-go theorem make me unable to do it from a mathematical point of view."

"Well, this question..."

Mr. Yang thought for a while, and finally smiled wryly: "As you can see, I am already so old, and I seem to have difficulty understanding what you said."

"But it is obvious that your research on this has gone deep enough, and you may be called the first person."

"I can't give you too many suggestions, but the only suggestion is that the lattice theory has probably completed its mission, perhaps, you can start from another angle."

"Another angle...?"

Li Mu fell into deep thought.

The full name of lattice theory is lattice gauge theory, which is one of the non-perturbative methods to deal with quantum field theory.

"One" means that there is not only this method, and of course the lattice gauge theory is also one of the more popular methods. \b

However, according to the general understanding in the physics world, the problems he encountered may be encountered no matter which non-perturbative definition method is used.

So this is another angle... how to change the angle?

In his mind, various non-perturbative definitions resurfaced.

Flow Algebra, Renormalization, Lattice...

Non-perturbative problems are situations that cannot be described by perturbation theory.

It can be said that the birth of the non-perturbation method can also be regarded as the method discovered by physicists after "changing the angle" when they found that the perturbation theory could not help them solve the problems existing in quantum field theory.

But now, in order to deal with problems that cannot be solved by non-perturbative methods, he has to change his perspective again.

It seems that there is a feeling of coming to a dead end.

"...renormalized, lattice... non-perturbative..."

Suddenly, Li Mu was taken aback.

Why limit the mind-set to non-perturbative methods?

To really change the angle, maybe it should be to trace the root cause.

As long as you use the perturbation expansion method, you will definitely encounter non-perturbation problems.

So he should...

While the storm in his mind was raging, Li Mu woke up from it, and then captured the key inspiration.

right!

Change the angle.

Just change the angle!

What he should do is to get out of the perturbation!

Surprise appeared on his face, and he said to Old Yang, "Thank you, Old Yang, for giving me a very important reminder!"

Hearing Li Mu's words, Elder Yang was taken aback immediately: "You... have an idea?"

How could he give any very important hints?

"Change another angle" is just his idea based on the current research on this issue in the physics community, but he no longer has the energy to think about how to change it. \b

Li Mu just smiled and said, "Yes, I have an idea."

Seeing Li Mu's expression, Mr. Yang has seen such an expression many times.

Like when Higgs came to him excitedly and said that the Higgs mechanism was discovered, it was also like when Steven Weinberg and Abdul Salam established the electroweak unified theory on Yang- Based on the Mills field theory and introducing the Higgs mechanism into Glashow's electroweak theory, the expression he showed when he obtained the current standard model.

So he knew that Li Mu had probably found the key to success.

He smiled and said, "I'm also very happy to be able to help you."

"Then I wish you success in advance."
