Chapter 387

The night was doomed to be sleepless.

When researchers are inspired, no one can stop them from burning their lives.

If something is meant to be done by God's hands, this evening is the time when the hand of God comes.

In their intense discussion, Li Zheng didn't even deliberately guide him. Just following the branches of the theory, the research route naturally emerged from the fog.

Among the three science cards launched before, high temperature superconductivity belongs to the field of experiment, which can be purchased with learning materials for inspiration at any time.

In the field of superconductivity, the meaning of high temperature is different from daily life. Even - 50 ℃ can be regarded as high temperature.

Even two or three years ago, if superconductivity could be achieved at temperatures as high as - 50 ℃, it would have made the headlines in nature.

Of course, the pursuit of temperature is only one direction in superconducting research.

For example, Yuan Yuan's graphene superconductor was realized at extremely close to absolute zero (- 271.45 ℃), and there was no breakthrough in temperature, but this did not prevent him from helping people get closer to the truth.

The pursuit of "high temperature" is more like a race to break the world record.

According to the classical theory and the experimental results for many years, the superconductivity of the same material at higher temperature will depend on the higher pressure environment.

Therefore, in the field of "high-temperature superconductor", scientific research competition has gradually evolved into an industrial competition. Who can create a higher pressure environment will have the capital to win.

This also explains why superconducting temperature records are updated several times a year.

As of this evening, the temperature record was temporarily - 23.15 ℃, achieved by a German team using lanthanum cyanide compounds.

Of course, it takes a million times more atmospheric pressure, about the same as the pressure of the earth's core.

This temperature is very encouraging to the layman, but the condensed matter scholars are very calm about it, and they have no doubt that the record will be broken in a short time, just look for something that can count on two million atmospheres.

Just like challenging the world record, the route itself is full of the flavor of the Olympic Games, and its honorary significance is far beyond the practical value. After all, the cost of building a 1 million atmospheric pressure superconducting cable is far higher than that of building a section of - 200 ℃ liquid nitrogen cable, and the latter can be realized long ago, and even will be installed in Xujiahui area of Shanghai Stock Exchange.

From Li Zheng's point of view, even if he bought the card and had a complete set of experimental parameters, I'm afraid he would not have a laboratory that can provide geocentric pressure. There are only three or five laboratories in the world, and he can't turn to him.

What's more, this card only needs 500 academic resources, which is the same level as the previous freeze electron microscope.

How could this mission be a 1500 level one!

In contrast, the magic horn model card fully meets Li Zheng's expectations.

Although there are three existing theories which seem to have nothing to do with superconductivity in front of it, as long as we can learn, there is no problem.

As for the description of the card, it is even better.

[magic angle model]

[prerequisite for the discovery of superconductivity theory. 】

[humans have already discovered the existence of Magic Horn, and even can calculate and infer the magic angle to a certain extent, but still can't fully understand it. 】

[exploring two-dimensional quantum tunneling and searching for electron deceleration belt will be the key to understand it. 】

[further extending it to three dimensions will be the real starting point of superconductivity theory. 】

[when you have finished the front-end content, you can spend 2000 points of learning resources to get inspiration. 】

[pre content:]

[quantum chromodynamics]

[tight binding model]

[strong correlation system]

we can see that in the end, this is not a wonderful problem.

Li Zheng is full of two words.

Learn, learn, learn, be quiet, learn, learn

Although there are some things mixed in, but in short, I can't wait to learn.

As for the three prepositions, tight binding model is the core tool of Portuguese papers, which must be learned. The solution of strong correlation system has been cited in the conversation, so Li Zheng only needs to

"Well..." Li Zheng held his chin and nodded, "I feel that our knowledge on quantum chromodynamics is still a little insufficient..."

"As you say, everything is a little inadequate." Because Lin qiojing knew Li Zheng too well, he just used to scold, "you just want to learn more!"

"Wait..." Solution of its dispute but a raised hand, after careful consideration, it was revealed a pair of "you boy is smart enough!" Li Zheng said that the strong interaction normative theory can provide a very basic perspective for the future research

On hearing the speech, Li Zheng pressed Lin yuejing, who could not wait. He waved his hand and said, "that's for sure. After studying the three parts of quantum chromodynamics, tight binding model and strong correlation system, we focused on collecting all theoretical papers on magic angles. In my spare time, I converted this grape tooth paper into a pure mathematical problem and handed it to guijianfengpin.""Well, that's it." He relieved his breath and got up to clean up the table. "I've found an exact direction. I don't know what time it is. If it's still early, I'll have a supper with you..."

After that, he raised his hand and looked: "how could it be more than six o'clock..."

"This..." Li Zheng swallows a mouth to spit, looking out of the window, "this is obviously morning, Lao Jie."

“！！！” He was surprised and quickly put the things into the bag and ran out, "it's over. My mother is going to scold me! Tomorrow Oh, no, see you in the evening

Li Zheng and Lin Yue Jing also looked at each other with a smile.

"It turned out to be a big mother, baby..." Lin Qijing grinned and carried his schoolbag.

"Not so superficial." Li Zheng hugged Lin qiojing to the door of the classroom, "imagine, these years, his mother should be the only rely on."

"In that case, he is the only support for his mother..." Lin Qijing suddenly felt a little sad. Leaning against Li Zheng's arms, he murmured, "I dare not think about this If one day my grandfather is gone Then I'll... "

Li Zheng eyes a stare, hand a tight: "then you are a person of mine!"

“？？？”

"I'm kidding. My grandfather is a hundred years old. He's the king of the millennium. He's 80000 years old." Li Zheng laughed and turned off the light and locked the door. He took the opportunity to raise his eyebrows and said, "this guy says that he will not marry. Nobody will look up to him, but I find that he has always kept a picture of Mr. Tang."

"Miss Tang?"

"Tang Zhifei, I have introduced him, such as Fu Xuefeng and Tao Feifei."

"This Is that right? " Lin Qijing scratched his head and thought seriously, "one should bear the smell of smoke and wine One should stand up to Well, isn't this house going to be a chemical laboratory? Can the old lady stand it? "

"No, no, tobacco, alcohol and foot odor can't react. More likely, one side will win a crushing victory." Li Zheng said, suddenly remembered what, "he seems to have not smoked for a long time."

"Yes, I remember you said he was smoking in class In fact, it doesn't seem to be? "

"Always so sober, it seems that I haven't drunk any wine." Li Zheng nodded his head and said, "in this case, he has been working hard. He just needs to resist the taste of Mr. Tang."

"Hello, when did the object become the competition of taste?" Lin Qijing waved his hand vigorously, holding his cheek in an understanding way. "Lao Jie has always refused to meet. He must feel that he is too small to be worthy of Mr. Tang. This time, he can just help him build up his self-confidence."

"Confidence? He doesn't lack confidence. "

"Alas Lin Qijing Zhen raised his hand and said, "you are handsome. You have a good family and study well, and you can also publish papers. You can't understand the psychological contradictions of normal people. Of course, he is absolutely confident in solving their disputes. But he is only a scientist in the classroom and laboratory. Once he leaves the campus and returns to the society, he is just an unmarried old lecturer in his 40s, while Mr. Tang No matter how smelly the feet are, they are beautiful women in their 20s. "

"Say it again."

"Teacher Tang is my foot..."

"Not here, the first sentence."

"The beginning? Even if you are handsome and have a good family... " Lin Qiaojing only found out what was going on when he said half of it. He thumped Li Zheng and said, "it's boring!"

"Ha ha." Li Zheng said with a laugh, "let him make his own decisions about Laojie. We are only responsible for doing a good job in this part of" scientists ". If this is OK, everything will be OK."

"I don't expect that much." Lin Qijing said with a light smile, "although I really feel that I can make something, it is the theoretical direction after all. Even if I make an article, what can I prove? Don't mention us. Even if it is published by people of the same level as Zhong Ping, I'm afraid it will take many years for such theoretical articles to be recognized If that's true, even if we really create a wonderful theory, the old Xie will be 50 or 60 years old Alas He can't talk earlier... "

"Why are you worried if he marries his daughter-in-law?"

"Heartache! Such a good teacher should have become famous long ago. Chu Youhua's assets are hundreds of millions. Well, the children's tuition fees are more than Lao Jie's salary. "

"That makes such a rich man?"

"It seems that they are shareholders of two quantum science listed companies, and I have heard from others."

"It's a bit of a pain indeed."

Li Zheng rubbed his chin diaphragm.

"If you have a chance to go back, you have to redistribute it..."

……

Time flies, learning is fast.

Although the weather is getting colder, thinking and inspiration are steaming like lava and crazily cracking.

One weekend in mid December, Xie Qifen had to take his mother to the hospital for medicine and had to take a day off. Li Zheng and Lin yuejing did not stop their efforts, but drove to an old community 5 kilometers away from the school.

According to the address, they climbed all the way to the fifth floor and knocked on a big green door with a simple and unsophisticated appearance.

It was a skinny man who opened the door, although "my grandfather really saw it." Lin Qijing nodded his head vigorously and said, "I always remember the publication day. Every time he cooked a meal on the morning of the publication day, he ignored me. He had to wait until noon. Now it is. I dare not call him on the publication day.""Ha, sure enough." Guijianfeng covered his mouth and said with a smile, "among the people I know, only Li Zheng can fight with him?"

"We are not fighting." Li Zheng nodded solemnly, "it is boil."

"You're with the eagles here."

"It means that." Li Zheng laughed, took out seven or eight pieces of paper and folded them together and handed it to Gui Jianfeng. "This is a paper that inspired us before. I transformed it into a mathematical form. You can help to have a look. You can have a few theoretical solutions."

"I understand physics, too. Don't do that." Guijianfeng shook his head and took the paper with a smile. After glancing at it, he immediately moved the chair back to the table. "I took back the words just now. I haven't seen this kind of physics. Just a moment. Give me 10 minutes. "

Li Zheng flustered: "no, you can see it in a week. I can't finish 10 minutes with my computer."

However, guijianfeng has ignored him and started to draw the draft paper.

Li Zheng saw this, but also had to look at each other with Lin qiojing, and sat down beside the bed.

It's not a matter to wait. After waiting for two minutes, Li Zheng raised his hand and pinched Lin Yujing.

"Why are you pinching me?" Lin Qijing covered his hands and cursed.

"I'm trying." Li Zheng is really a positive face, seriously looking to guijianfeng, who is eager to write, "how far can he concentrate on his study like this?"

"What are you doing with me?"

"Idle is idle. I think it's better to make some voices and do some things to see how stable his learning mind is."

"Well Why am I not pinching you

"Yes, come on, pinch it."

"Don't stand up. What kind of posture is this?"

"Don't you? I'll pinch you. "

"You go, go, go!"

During the dispute, guijianfeng suddenly waved his hand and said without raising his head.

"Five No, no, wait a minute. Eight solutions. "

Li Zheng's body was shocked, and he could not care about pinching and being pinched.

It is the magic angle calculation process of double graphene that is handed over to guijianfeng.

Finally, five possible magic angles are given, which is the first reaction of guijianfeng.

But eight? Is there any other situation that the computer has not considered?

"And then?" Li Zheng rushed over and asked, "how did those three come out?"

"It's only in theory. If you want to use imaginary numbers, you can't understand any more tools." GUI Jianfeng twisted the pen and turned over the paper, "I haven't calculated it yet, it's just the feeling, but I've done so many calculations. The accuracy of feeling is basically 100%. Give me half an hour and I'll have a try."

"Please!"

Looking at guijianfeng's full swing, Li Zheng carefully returned to his bed, and did not dare to do it again. He just looked at him silently.

"Mathematics alone..." Even Lin Yue Jing had to offer worship, "there is no room for resistance in front of the wind..."

"Since he can count For more than ten years, I spent 14 hours a day doing math... " Li Zheng shook his head. "I can't imagine his brain structure any more..."

"I really want to see him and Lao jiejie spell the problem..."

"Even if the two universes are going to collide..."
