From Almighty Scholar to Chief Scientist

Lin Xiao replied: "Well... probably out of a kind of intuition."

"intuition?"

"Well." Lin Xiao nodded: "I think the world should be unified, regardless of the superconductivity of high-temperature superconductors or the superconductivity of low-temperature superconductors, since their ultimate explanation is the unimpeded flow of electrons, then I believe , They can all be explained by a theory in the end, not to mention, whether it is high temperature or low temperature, it is only defined by us humans, so I think there is no need to care about this.”

Hearing what Lin Xiao said, the professors were stunned again.

The world is unified?

There are people with similar thoughts, such as Chen Xun, who immediately agreed: "If you say so, I also think it is possible."

If the world is unified, the principle of superconductivity may be the same. Lin Xiao's idea convinced Chen Xun.

However, some people expressed their objection: "Professor Lin, whether the world is unified or not is still to be answered by people hundreds or thousands of years later, but I think that there are linear and nonlinear in mathematics. Can it also be unified?"

This question made them silent for a while, but someone soon said: "Professor Hu, I don't think it is necessary to ask your question? Nonlinear and linear are just two different ways of expressing, just like superconductivity and superconductivity." Non-superconducting, we can’t unify superconducting and non-superconducting, right?”

This Professor Hu shook his head and said: "Superconducting and non-superconducting are two physical phenomena, of course they can be different, but linear and non-linear are mathematical tools. Since mathematics also pursues the Langlands Program, unifying other mathematical tools Come on, why can’t linear and nonlinear try to unify?”

"Then you are a bit irrational! Linearity is a straight line, and nonlinearity is not a straight line, such as a curve. This is also an actual phenomenon!"

"You're the one who uses strong words!..."

……

Accidentally, two physics professors quarreled over a math problem. Seeing this scene, Lin Xiao couldn't laugh or cry.

He immediately dissuaded him: "You two, come on, come on, it's just such a question, we don't need to quarrel over it."

After some restraint, the two professors finally calmed down.

Seeing the two professors stop, Lin Xiao breathed a sigh of relief, but then said: "But, Professor Hu, I actually think that nonlinearity and linearity may be unified, and even now I can show you Here comes a proof."

Professor Hu stared: "What evidence?"

Lin Xiao replied: "Riemann's conjecture."

Hearing this, they were stunned for a moment, and then they all showed sudden expressions.

In Riemann's conjecture, isn't it possible to classify the prime numbers that seem to be invisible to the law as a situation that can be described by a straight line?

"Professor Hu, what do you say?" The one who quarreled with Professor Hu just now did not forget to say something.

Professor Hu snorted, and said, "This hasn't been proven yet, so it doesn't count."

Seeing that Professor Hu was still talking hard, everyone present laughed.

Professor Hu couldn't hold back his old face from laughing, and said: "Even if it is proved, it is only a special case. The unification of linearity and nonlinearity is to unify all situations!"

However, Lin Xiao said at this time: "I can also unify all nonlinearities into linearity now."

Professor Hu was taken aback for a moment, and everyone else was also shocked, looking at Lin Xiao one after another.

"Now? Professor Lin, are you sure?"

Can Lin Xiao unify all nonlinearities into linearity now?

How is this possible?

Li Min, who has been watching by the side, also showed an incredible expression. How can his great mentor achieve the unification of linearity and nonlinearity now?

Lin Xiao didn't speak, just took out a piece of paper, and drew a few curved lines on it, then picked it up, showed it to them, and asked: "Look, is this line non-linear? "

Everyone present nodded, and they didn't know what Lin Xiao was going to do to make this curve into a straight line.

At this time, Lin Xiao smiled slightly, and gradually turned the paper over, so that the paper faced the ceiling, and the whole paper was parallel to their line of sight, and then he said: "Everyone, now look at the picture I drew on it. A curve, should it be a straight line in your eyes now?"

Listening to Lin Xiao's words and looking at the paper at the same time, everyone in the office was stunned.

Yes, that non-linear curve has now become a straight line in their eyes - although they cannot see the line on the paper because their line of sight is completely parallel to the paper, as long as the entity of the paper is ignored , The curve drawn by Lin Xiao is a straight line for their line of sight!

Chapter 321 Look at it from another angle!

Although Lin Xiao's so-called method of unifying all nonlinearities into linearity is actually a kind of opportunistic trick, because it is obviously not described from a mathematical point of view, and there is no rigorous proof in the middle. All the information carried by the original curve is lost, that is, we cannot know the specific appearance behind it from this straight line.

But it is still meaningful, especially for the physics professors present, even Li Min, who is only a graduate student, knows that from a mathematical or physical point of view, this is indeed a certain degree of linearity and nonlinearity. Unification, the high-end point, is the transformation from three-dimensional to two-dimensional. A two-dimensional foil compresses the original three-dimensional curve into a two-dimensional straight line.

The only problem is that equivalence is not achieved.

"I admire you, as expected of Professor Lin."

Professor Hu expressed his admiration. Although deep down, Lin Xiao hadn't convinced him yet, Lin Xiao's way of thinking still amazed him.

Lin Xiao smiled modestly, then put the paper back in his hand, and said: "Okay, everyone, let's not talk about this matter for now, let's go back to our previous superconducting issue."

Several professors nodded.

Chen Xun said, "Professor Lin, do you have any idea about the mechanism of high-temperature superconductivity now?"

Lin Xiao nodded: "Well, you should all know Landau's Fermi liquid theory, right?"

Several professors nodded. Physicists who study superconductors will know more or less about this thing.

"I think the final answer lies in the similarities and differences between Fermi liquids and non-Fermi liquids."

Several professors frowned.

"A non-Fermi liquid?"

Understanding non-Fermi liquids is an important issue in condensed matter physics. If Fermi liquids can be explained, it will be very helpful for condensed matter physicists to understand the behavior of fermions, especially for the The understanding of electronic behavior will also be greatly developed.

But I have also said that this is still an important problem in condensed matter physics. So many physicists in the world have not solved it, and more strictly speaking, this is not a purely physical problem, but a mathematical physics problem. These professors don't think they can handle it.

A professor asked, "Professor Lin, what do you think?"

Although it is not kind to always ask Lin Xiao, but there is no way, they also want to come up with some results. They don't want to come up with a superconducting material that can be superconducted in the refrigerator in their lifetime, but if they can create a superconducting material for the high-temperature superconducting mechanism Bringing some important results is also very meaningful to them, maybe they can become a Zhao Xian academician again.

The academician Zhao Xian that Lin Xiao met at the beginning was the Taishan Beidou in the superconducting world of Huaguo, including the two winners who won the Nobel Prize in 1987. It was only through the contribution of the director that their theory was confirmed and they won the Nobel Prize in Physics.

Therefore, for these professors who study superconductivity, it must be too late to change careers, so becoming the next Academician Zhao Xian has become their ideal.

As for why they pinned their hopes on Lin Xiao, it was naturally because in their eyes, Lin Xiao's status in physics might give them a little hint.

Lin Xiao didn't hide his secrets either, and said, "For the time being, I think we should study it from the perspective of perturbation theory."

"The Fermi liquid model is a quantum system. According to the concept of Pauli exclusion, as the fermion particles start to interact with each other, the fermion spin, charge and momentum corresponding to the occupied state remain unchanged... ..."

"Well, some aspects still need to be explained from a mathematical point of view."

With that said, Lin Xiao picked up the pen and began to write on the paper.

[G(ω,p)≈Z/(ω＋μ－ε(P)……]

In this way, Lin Xiao began to share his research on this aspect in about a month.

Of course, his current research is still shallow, and there is still a long way to go to truly solve this problem.

"Finally, regarding the mechanism of high-temperature superconductivity, the academic community also has a very interesting argument, that is, the spin fluctuation mechanism. I think that after solving the problem of non-Fermi liquids, it will reach a very organic connection with the spin fluctuation mechanism. .”

"Well...that's my basic idea."

After listening to Lin Xiao's sharing, several professors felt that they benefited a lot.

Although condensed matter physics itself does not have very high requirements for mathematics, if you want to do better, the requirements for mathematics are very high.

What Lin Xiao shared with them included a lot of mathematics content, which brought a lot of help to physics professors who are not very good at mathematics.

"Professor Lin, thank you for sharing."

They all thanked each other.

Lin Xiao smiled and waved his hands, and said, "You're welcome, knowledge needs to be communicated to develop better!"

"Of course!" Speaking of this, Lin Xiao paused, showing his minions: "If you want to communicate more, you may wish to join the superconductivity laboratory of my Dingguang Research Institute. Professor Chen Xun has already joined."

Hearing Lin Xiao's invitation, everyone present was taken aback for a moment, and then they all smiled: "Professor Lin has said so, so of course we are very willing."

Lin Xiao laughed immediately: "Okay, then I look forward to seeing you in the Dingguang Research Institute in the future."

"That's all right."

Several professors nodded one after another. It is certainly good for them to be able to go to the Dingguang Research Institute, and then they left here without bothering.

Looking at the closed door, Lin Xiao suddenly thought about it. He dragged all these professors over by himself. By then, the dean of the School of Physics will not come to trouble him, right?

In addition, as a master of Beijing, he seems to have picked up a lot of wool from the University of Beijing. He poached quite a lot of masters of Beijing.

"Well...don't care, wait until someone comes to see me."

Thinking of this, Lin Xiao smiled.

The happiest thing is nothing more than pulling wool.

But at this time, he glanced at Li Min who had not left, and asked with a smile: "What's the matter? You want to go to the Dingguang Research Institute too?"

Li Min's eyes lit up: "Is it possible?"

Lin Xiao smiled: "No."

Li Min: "..."

"If you want to join the Dingguang Research Institute, it depends on your performance. As long as you are good enough, the Dingguang Research Institute will definitely open the door for you."

Lin Xiao said.

Even if Li Min is his student, he will not let him go through the back door.

If he doesn't even abide by his own rules, it's obviously not easy to show selflessness to others.

Li Min nodded, indicating that he understood.

However, he then remembered what the professors were arguing just now, and asked, "Speaking of which, Professor Lin, do you really think that linear and nonlinear things can really be unified?"

Lin Xiao asked with a smile, "Why can't it be realized?"

"But... I always feel a little unbelievable." Li Min said.

What would it mean if nonlinearity could be unified into linearity?

This is simply another P=NP situation, even more terrifying than the effect of P=NP.

The world is nonlinear, and nonlinear systems are always more complex than linear systems, such as chaotic systems. When people solve many problems, they also try to transform nonlinear problems into local linear problems.

After all, when doing math, who doesn't love doing y=ax+b?

And something like y=ax^2+bx+c obviously makes people hate it.

And once nonlinearity can be unified into linearity, it means that all nonlinear problems in the world can be infinitely simplified.

Just like the special case mentioned by Lin Xiao before, the Riemann conjecture and the distribution of prime numbers, the distribution of prime numbers is nonlinear, but once the Riemann conjecture is proved, the nonlinear problem of prime number distribution becomes a Riemann zeta function This linear problem of a straight line in the complex plane Re(s)=1/2.

Lin Xiao smiled slightly, "There are still many incredible things in the world, just like if you lived in the 18th and early 19th centuries, when the world was still ruled by Euclidean geometry, if you heard Roche geometry at that time, would you also Think this is incredible? And then follow the people to spit on Lobachevsky?"

"At that time, you probably also felt that it is absurd to say that on a plane, there are at least two straight lines that do not intersect the known straight line through a point outside the known straight line."

"But looking at it now, Roche Geometry is clearly an important achievement worthy of ten Fields Medals."

"Even, everyone of us can do this - as long as we are next to the black hole, we can easily go to a point outside the known line and find at least two lines parallel to this line."

Listening to Lin Xiao's words, Li Min nodded thoughtfully.

Rochester geometry is a mathematical theory that can affect the development of philosophy. Thinking about the meaning brought by Rochester geometry can easily make people feel enlightened.

However, Li Min quickly came to his senses, recalling that Lin Xiao "proved" the unity of nonlinearity and linearity just now, he said with sincere admiration: "However, Professor Lin, you just changed the angle and combined nonlinearity and linearity. The unified method is really awesome, I have to play tricks with Zhao Guodong and Chen Mingkai later."

Lin Xiao couldn't help smiling, waved his hand and said, "Go."

"Yeah." Li Min nodded, and ran away immediately, obviously impatient to pretend to be this bully.

But Lin Xiao lowered his head and looked at his piece of paper with a curved line again.

"Another angle..."

After silently reading a sentence from Li Min, Lin Xiao's eyes flickered suddenly.

"Another angle, Fermi liquid, non-Fermi liquid..."

Suddenly, a flash of light flashed in his mind.

"I have described this kind of cluster particle behavior as liquid, why don't I look at it from the perspective of fluid?"

His mind grew brighter and brighter, until finally, a smile appeared on his face.

"I would like to thank Li Min...Well, let's give him a little trouble in the future."

Then, he picked up a pen and started an extremely complicated mathematical deduction.
