Jinling Institute for Advanced Study.
A laboratory at the Institute of Physics was engulfed in smoke.
Sheng Xianfu was smoking one cigarette after another as he looked at the design sketch on the table. He sighed and said, "Why do you think Professor Lu is suddenly researching the Yang-Mills equations?"
Li Changxia, who was sitting next to him, shook his head and said, "I don't know."
Sheng Xianfu said anxiously, "Then are we still going to do fusion batteries?"
He gave up the opportunity to become the director of the Southwestern Institute of Physics to come here and work with Professor Lu on the miniaturization of controllable fusion. It had been two months since then, and there was no progress at all.
But now, not only was there no progress, the academic leaders of the project were all working on other projects.
"I don't know."
Sheng Xianfu couldn't help but say, "Can you say something else?"
Professor Li Changxia scratched his head and said, "Theoretically speaking, if we can establish a unified relationship between the strong interaction and the electromagnetic force … It would be more beneficial for us to deepen our understanding of nuclear fusion conditions."
When he said this, his tone was also full of uncertainty.
After all, he was a well-established engineering professor. He was more confused than Sheng Xianfu at this moment.
Sheng Xianfu glanced at him.
"Then what? How long do you think it will take to transform theoretical results into practical technology? Also, even if we deepen our understanding of the GN force, what can we do? It's not like we can turn the reactor into a flower. "
Li Changxia sighed and said, "But we don't have any other way."
Sheng Xianfu didn't know what to say.
Lu Zhou hit the nail on the head.
Even if they didn't do this, there was nothing they could do.
In order to solve the problem of reactor heat dissipation, they had already designed more than a dozen solutions. However, none of the solutions passed the technical feasibility test. Even the best one melted down after 34 seconds of operation.
"Maybe the idea of using a high temperature to complete the ignition itself is wrong." Sheng Xianfu pondered for a while and suddenly said, "Maybe like you said before, if we can find a way to reduce the temperature of the fusion reaction, our research might be easier."
Professor Li Changxia shook his head and said, "I think it's impossible to make a small controllable fusion device and put it on a spacecraft."
The silence lasted for a while.
Sheng Xianfu, who was thinking hard about the design sketch on the table, suddenly sighed and put out the cigarette in the ashtray.
"I'll go find Professor Lu."
As he spoke, he crumpled the sketch on the table into a ball and stuffed it into his pocket. Then, he stood up from the chair and strode out of the laboratory …
…
When Sheng Xianfu arrived at Jin Ling University, Lu Zhou was teaching the students in the lecture hall.
Or to put it more accurately, a lecture on quantum mechanics.
Sheng Xianfu quietly walked into the lecture hall from the back door. When he saw the crowded classroom, he couldn't help but feel emotional.
When he was at the Fuyang Institute of Matter Research, he was also a lecturer at the nearby University of Science and Technology of China. However, his classes were on controllable fusion and plasma physics, and the lecture hall was never half full.
Of course, this might be because controllable fusion was too unpopular at the time, so not many people took his class …
Sheng Xianfu didn't disturb Lu Zhou's class. He found an empty seat in the last row of the lecture hall and sat down. He 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 the students, a student raised his hand and asked.
"Professor, can you tell us how to understand the Yang-Mills equations from a mathematical perspective?"
When this question was raised, it immediately received a lot of support.
It could be seen that there were a lot of physics students who were interested in this theory.
"… It's still too difficult for you to understand this equation with your current level of knowledge." Lu Zhou nodded at the student who asked the question and said, "If you're interested, you can take a bus to the old campus on May 20th. I will explain this problem in detail during the report. "
Suddenly, someone in the audience complained in a low voice.
"But it's too difficult to apply for admission."
This was indeed a problem.
This kind of international academic report wasn't just for the presenter, it was also for the participants.
Lu Zhou, who was standing on stage, heard the complaint. He thought for a bit and smiled.
"Then I'll give a simple explanation."
Lu Zhou cleared his throat and spoke with a serious look on his face.
"If we want to understand the Yang-Mills equations mathematically, we first have to know what it is.
"Simply put, the Non-Abelian symmetry group given by the Yang-Mills equations is a special kind of gauge theory. In a classical sense, this theory is similar to Maxwell's theory. It replaces the Abelian abelian group U (1) with the more general compact gauge group G … "
When it came to mathematics, it was useless to just talk about it.
Lu Zhou picked up a piece of chalk and began to write on the blackboard behind him.
[If 0 = dA ∙ F, then the Lagrangian operator for the passive Yang-Mills field can be derived variationally: L = 1/4g ² · * Tr (F '∙ F) …]
[…]
Undergraduate students didn't even need to think about the proof of the Yang-Mills equations.
Even if the Princeton professors wanted to understand his theory, they would have to start from the L Manifold thesis.
What he was writing on the blackboard was just some explanations of the Yang-Mills equations itself.
At most, he would add a little bit of his own ideas while explaining the proposition.
Just like that, there were more and more calculations on the blackboard.
Lu Zhou was getting into the zone. He couldn't seem to stop writing, and his explanation became less and less.
The students sitting in the lecture hall all looked at the blackboard with a muddled expression.
At first, they could barely understand it, but later on, they were deeply impressed by the esoteric theory.
Later on, it wasn't just the students, even some physics professors who came to listen to the lecture began to struggle.
What is Lu Zhou writing?
The more they read, the more they felt …
The content of Lu Zhou's lecture seems to be a bit different from their major?
Is this guy really talking about the Yang-Mills equations?
A lot of old professors stared at the blackboard with their mouths agape. They even began to doubt their own lives.
Professor Lu Zhou was sitting in the front row of the lecture hall. He stared at the lines of calculations on the blackboard with his eyebrows furrowed.
Suddenly, he keenly captured a keyword from the equation on the blackboard, and his pupils suddenly contracted.
"… The non-zero asymptotic constant of the vacuum state reduces the gauge group to a U (1) subgroup!"
He was trying to use a mathematical method to explain the strong interaction Yang-Mills existence and mass gap!
Professor Lu Zhou's eyes were filled with eagerness.
However, he looked at the blackboard expectantly, hoping that Lu Zhou would write all the way to the last step. However, Lu Zhou seemed to have let him down.
Lu Zhou, who was excited a second ago, suddenly stopped writing. He took a step back and looked at the calculations on the blackboard. He stood there for a long time.
It seemed like he couldn't continue writing.
He scratched the back of his head and threw away the chalk in his hand. He turned around and looked at the muddled students. He smiled embarrassedly.
"Sorry … I went too far just now."
The physics professors, who were waiting for the final result with Professor Lu Zhou, nearly spat out blood.
F * ck!
You're only halfway through the calculation, why don't you finish the rest!
However, unlike most of the professors in the lecture hall, Sheng Xianfu, who was sitting in the back row, had his pupils gradually lit up.
Although he didn't really understand the content of the lecture, he got unexpected inspiration from it.
"As long as the distance between the nuclei is small enough …"
As he muttered to himself, inspiration flashed through his mind.
Even though this might sound crazy, he did think of a possible controllable fusion reactor model.
If it made sense in theory ….
Maybe they really had a way to liberate the energy in the nucleus in a new form under reaction conditions that were lower than hundreds of millions of degrees …
