Chapter 617 Inspiration Is Contagious

Jinling Institute for Advanced Study.

In a certain laboratory of the Institute of Physics, smoke is swirling at the moment.

Sheng Xianfu, who was smoking one cigarette after another, flicked the ash, looked at the design sketch on the table that had been modified many times, sighed and said, "You said that Professor Lu suddenly started to study Yang Mier?" Has the Stein equation come up?"

Sitting next to him, Li Changxia, who was looking at the documents, shook his head: "I don't know."

Sheng Xianfu said with a worried face: "Then is this fusion battery still working?"

He gave up the opportunity to be the director of the Southwest Institute of Physics and came here to follow Professor Lu in the miniaturization of controllable fusion. As a result, almost two months have passed, and the research topic still has not made any progress.

It's good now, not to mention that there is no progress, the academic leaders of the project are all busy with other projects.

"……do not know."

Sheng Xianfu couldn't help but said: "Except I don't know, can you say something else?"

Professor Li Changxia scratched his hair, made a helpless expression and said: "Theoretically speaking, if we can establish a unified relationship between strong interaction and electromagnetic interaction...it will be more beneficial for us to deepen our understanding of the conditions of nuclear fusion some."

When he said this, his tone was also full of uncertainty.

After all, he himself is considered a well-developed engineering professor. If he is confused, he is much more confused than Sheng Xianfu at the moment.

Sheng Xianfu glanced at him.

"And then? How long do you think it will take for this kind of theoretical achievement to be transformed into practical technology? And what do you think we can do even if we have deepened our understanding of nuclear force? Can we turn this reactor into a flower?"

Li Changxia sighed and said, "But now there is no other way."

Sheng Xianfu couldn't say anything this time.

This sentence is on point.

Even if they don't, they have nothing to do right now.

In order to solve the heat dissipation problem of the reactor, they have designed at least a dozen sets of solutions for this purpose. However, none of the solutions could pass the test of technical feasibility. Even the best one, the reactor was melted down after running for 34 seconds.

"Perhaps the idea of ​​using high temperature to complete the ignition itself is wrong." Sheng Xianfu, who pondered for a while, suddenly said, "Perhaps as you said at the beginning, if there is a way to reduce the temperature condition of the fusion reaction, our Research might be easier."

After flicking the soot, Professor Li Changxia shook his head with a self-deprecating smile: "I now feel that it may not be feasible to make the controlled fusion smaller and put it on the spacecraft."

The silence lasted for about a while.

Sheng Xianfu, who was contemplating the design sketch on the table, suddenly sighed, reached out and pressed the cigarette butt into the ashtray.

"I'm going to find Professor Lu."

As he said that, he crumpled up the sketch on the table that had been changed many times and stuffed it into his pocket, then stood up from the chair, and strode towards the outside of the laboratory...

...

When Sheng Xianfu arrived at Jinda University, Lu Zhou was teaching students in the lecture hall.

Or to put it more accurately, a lecture on quantum mechanics.

He quietly walked into the lecture theater through the back door, and seeing the crowds in the classroom, Sheng Xianfu couldn't help feeling deeply moved.

When he was at the Luyang Institute of Matter, he also served as a lecturer at the nearby University of Science and Technology, but the lecture hall was never half full for the theoretical courses on controllable fusion and plasma physics.

Of course, this may also be because controlled fusion was too unpopular at the time, and not many people took his class...

Without disturbing Lu Zhou's class, Sheng Xianfu managed to find a vacant seat in the last row of the auditorium, and then listened to the lecture while patiently waiting for it to end.

When he walked into the classroom, the lecture seemed to have entered the second half.

During the interactive session with students, only one student raised his hand and asked.

"Professor, can you tell us how to understand the Yang-Mills equation from a mathematical point of view?"

When this question was brought up, it was immediately echoed by many people.

It can be seen that for the students of the Academy of Physics, there are still many people who are interested in this theory.

"...With your current level, it is still too difficult to understand this equation," Lu Zhou nodded to the student who asked the question, and said with a smile, "If you are interested, you can consider waiting for May 20th. Take a car and go to the old campus to listen. I will explain this issue in detail at the report meeting."

At this time, someone in the audience complained softly.

"But that admission qualification is really too difficult to apply for."

This is indeed a problem.

For this kind of international academic report meeting, the threshold is not only for the speakers, but also for the participants.

Hearing the whispered complaint just in time, Lu Zhou who was standing on the stage thought for a while, then smiled and said.

"Then I'll just talk about it briefly."

After clearing his throat, Lu Zhou's expression slightly adjusted, and he spoke.

"To understand the Yang-Mills equation mathematically, we first need to know what it is."

"In simple terms, the non-Abelian symmetry group given by the Yang-Mills equation is a special kind of gauge theory. In the classical sense, this theory is similar to Maxwell's theory, which is replaced by the more general compact gauge group G It is the Abelian exchange group U(1)..."

When it comes to mathematics, it's useless to talk about it.

Lu Zhou picked up the chalk and started writing on the blackboard behind him.

[If 0=dAF, it can be derived from the Lagrange operator of the passive Yang Mills field: L=1/4g·∫Tr(F'F)...]

【…】

The proof of the Yang-Mills equation is a no-brainer for undergraduates.

Even the professors of Princeton, if they want to understand his theory, they have to start from the paper on L manifolds.

What he is writing on the blackboard now is just some explanations about the Yang-Mills equation itself.

At most, it's just a little bit of my own thoughts that I've incorporated while explaining this proposition.

In this way, there are more and more calculations on the blackboard.

Lu Zhou, who was gradually entering the state, seemed to be unable to stop writing, and the language of explanations became less and less.

The students sitting in the lecture theater looked at the blackboard in bewilderment.

If you can barely understand it at the beginning, you have been deeply impressed by this profound theory later on.

Later, not only the students, but even some professors from the School of Physics who came to attend the lecture gradually felt the strain.

What is this guy writing about?

The more they looked down, the more they felt...

What Lu Zhou said seems to be a bit different from their major?

By the way, is this guy really talking about the Yang-Mills equation?

Many old professors who stared at the blackboard dumbfounded even began to doubt life.

Sitting in the front row of the lecture theater, Academician Lu stared at the lines on the blackboard, frowning tightly.

Suddenly, he keenly caught a line of key words from the formula on the blackboard, and his pupils shrank suddenly.

"...the nonzero asymptotically constant value of the vacuum state reduces the gauge group to a U(1) subgroup!"

He is trying to explain the mass gap of the strong interaction mathematically!

For a moment, Academician Lu's eyes were filled with eagerness.

However, just as he was looking at the blackboard with full expectation, expecting that Lu Zhou could write all the way to the last step, Lu Zhou seemed to live up to his expectations.

I saw that Lu Zhou, who was still high just a second ago, suddenly stopped the chalk in his hand, stepped back half a step, looked at the calculation formula on the blackboard, and stood there thinking for a long time.

It seems that I can't write any more.

He scratched the back of his head, dropped the chalk in his hand, turned to look at the classroom, looked at the stunned students, and smiled a little embarrassedly.

"I'm sorry... I went a little too far just now."

Upon hearing this sentence, the professors of physics who were waiting for the final result like Academician Lu almost spit out a mouthful of old blood.

Fuck!

You've done half of the calculations, but you've finished the rest!

However, unlike most of the professors present, Sheng Xianfu, who was sitting in the back row, was getting brighter in his pupils at this moment.

Although he didn't understand the content of the lecture itself, he got unexpected inspiration from it.

"As long as the distance between nuclei is small enough..."

Talking to himself, some inspiration flashed from his mind.

While that might sound crazy, he does have one possible model for a controlled fusion reactor in mind.

If it makes sense in theory...

Maybe, they really have a way to release the energy in the nucleus in a new form under the reaction conditions of a temperature lower than hundreds of millions of degrees...
