Chapter 313 Studying superconductivity?

In the afternoon, Lin Xiao came to the dining place and had a meal with Zheng Ronger's parents.

For this meal, Zheng Cheng and Xu Yan could be said to be grateful to Lin Xiao in every possible way.

If Lin Xiao hadn't notified them in time to publish the proof of Lin's conjecture on arxiv, otherwise they might not have been able to grab the paper on superconductors.

Because this paper itself was a feasible direction discovered in the project they had done. After Zheng Cheng discovered it at that time, he concluded that as long as Lin's conjecture could be proven, he could complete a paper that could be published in Nature.

But at that time, he had no idea that Lin's conjecture could be proven in a short time, so he shared it. There were other people working on the project with them, so everyone knew about it. .

So if they don't know in time that Lin Xiao has proved Lin's conjecture and announced it, if it's a little later, they might be snatched away by others.

In that case, they would not be able to return to Beijing to work as they wished, let alone the National Laboratory of Condensed Matter Physics.

"Professor Lin, thank you so much! We are not people who like to drink, so Xu Yan and I will drink tea instead of wine and toast you first!"

Zheng Cheng and Xu Yan raised their tea cups to express their gratitude to Lin Xiao.

Lin Xiao waved his hand with a smile, raised his tea cup and clinked it with them. After taking a sip, he smiled and said: "No need, I already said it's not necessary. Just thank you a few times before."

"Hey, it must be necessary, so you don't need to say more."

Zheng Cheng put down the tea cup with a smile, and then poured it for Lin Xiao. This restaurant was considered a relatively high-end restaurant, and the tea was not cheap at all.

Then the two casually chatted for a while. Zheng Cheng also had to express his congratulations to Lin Xiao for leading China to successfully develop a lithography machine. By the way, he also expressed his gratitude for Lin Xiao's words that made the United States abandon its original plan some time ago. I admire you very much.

"If you ask me, the two academies will have to appoint you as an academician next year. The Academy of Sciences and the Academy of Engineering will have to appoint you as an academician directly."

Lin Xiao shook his head and smiled: "That's not necessarily the case. Being an academician will make you popular."

After he came out of Dingguang Research Institute, there were many people who were jealous of him.

After all, the funding his research institute can apply for every year is more than the sum of ten other research institutes.

The amount of annual funding is only so much. It can be said that if any research institute has less funding, it basically goes to him.

In addition, research institutes can also cooperate with each other, so many academicians have approached him to cooperate before. The conditions for cooperation are naturally that their Dingguang Research Institute provides funding and then shares the results.

But the final results actually belong to the country, and the person in charge of the project belongs to others, so the final title is naturally theirs.

How could Lin Xiao agree to such a thing?

Those funds are better left to the researchers of their institute. At least, the people in his institute are first-class researchers, and maybe they can produce better results.

So from this aspect, Lin Xiao was tantamount to offending these academicians.

In addition, not to mention that he rejected a lot of people who wanted to join the Dingguang Research Institute through connections.

There are too many people to offend, and those people have complicated relationships in the academic world. If you want to become an academician, you need to vote. At that time, those who don't deal with him can legitimately veto him because he is too young. Him, don't vote for him.

So for now, Lin Xiao has not considered becoming an academician at all, let alone an academician of the two academies. There are so many academicians in China, and there are only about thirty academicians who are academicians of the two academies. .

When he heard Lin Xiao's answer, Zheng Cheng was stunned, shook his head, sighed, and turned to talk about other things, "I won't talk about that anymore. It's too abominable that you won't be awarded the Nobel Prize this year."

Lin Xiao shook his head and didn't care, "Look, now that I have built a lithography machine, do I still dare to attend the Nobel Prize award ceremony?"

Xu Yan next to her couldn't help but ask: "I have never heard of anyone being arrested for attending an award ceremony."

Lin Xiao smiled and did not answer.

Zheng Cheng answered for Lin Xiao: "Professor Lin is not one of those ordinary winners. Professor Lin's words just a few days ago made the Americans withdraw their plans. This can be regarded as a strategic effect."

Lin Xiao laughed again, and then said: "Okay, okay, let's not talk about these awards or not. Eat the food first, eat the food."

Then several people continued to taste the dishes of this high-end restaurant.

When they were almost done eating, Lin Xiao suddenly asked: "By the way, how is your research on superconductors going?"

"The research status of superconductors."

Zheng Cheng spread his hands, "It's still half-dead. We haven't figured out the mechanism of high-temperature superconductivity yet. Even now, there are fewer people studying superconductors than before. Condensed matter physics, although superconductors are the largest project. , but no one saw any hope of success, so a lot of people turned to other materials."

Hearing this, Lin Xiao couldn't help but smile: "That's true."

"Haha, Xu Yan and I also feel that there is really nothing to study, and we are thinking about whether to change the direction. For example, there are many people studying Bose-Einstein condensates. This stuff is quite interesting. In June this year, " There is a paper in Science that uses a Bose-Einstein condensate to create a continuous time crystal."

"I've heard of that paper too."

Lin Xiao nodded. The term time crystal is not unique to fantasy novels. It also exists in physics. In short, this thing, Poincaré regression and closed class curve are all regarded as the end of the universe. and start.

Xu Yan said at this time: "However, Professor Lin, after your original electron topological bonding theory came out, there are now many people studying superconductors, especially topological superconductors."

"There were relatively few people studying topological superconductors in the past. Originally, a lot of people were studying superconductivity under high pressure and magic angle graphene. But after your electronic topological bonding theory emerged, it became topological superconductivity. It brings a certain theoretical foundation.”

Lin Xiao nodded: "I also know this, which is why I ask you this matter."

Zheng Cheng couldn't help but express surprise: "Professor Lin, are you interested in superconductors now?"

Lin Xiao shrugged: "It's okay for the time being anyway, it's okay to do some research."

Zheng Cheng immediately smiled and said: "Then it seems we have to change direction as soon as possible. If this problem is in the hands of Professor Lin, it may be solved after a while."

Lin Xiao couldn't help but laugh, "This is a superconductor, and success is not guaranteed by success."

Zheng Cheng then said very decisively: "Hey, you have already made things like RDX pure silicon crystal. You may have also made superconductors. You know, the whole world now wants to know how RDX pure silicon crystal is made." from."

Xu Yan next to her looked at her husband as if she were a fanatical fan of Lin Xiao, and couldn't help but shake her head.

Lin Xiao smiled and waved his hand: "These two are not the same thing and cannot be discussed together."

Of course, in his mind, RDX pure silicon crystals and superconductors should be equally difficult to research.

After all, RDX pure silicon crystal requires a system of wave coherent superposition equations to play a role in it.

However, even though that is said, superconductors, especially high-temperature superconductors and room-temperature superconductors, are still not easy to study.

Among them, as long as room-temperature superconductors are born and the production cost is low enough, the entire world's energy pattern will undergo huge changes.

After all, energy is a symbol of civilization level.

Of course, superconductors are only an energy transportation technology. However, since electric energy is the most important form of energy in today's human society, superconductors can transport electric energy without damage, and its importance goes without saying.

After thinking about it, Lin Xiao raised his eyebrows and asked in his mind: "How many truth points are needed for the system, room temperature superconductor materials and preparation methods, and at the same time, the cost is within an affordable range?"

System: "Based on the current situation of the host, 500 truth points are needed to exchange room temperature superconducting materials and their preparation methods with an affordable cost."

"500 truth points!"

Lin Xiao suddenly became energetic because he could definitely afford to redeem it!

It’s even a room-temperature superconductor!

What is a room temperature superconductor?

That is something that can directly make China take off!

China's wire transmission system can be said to be the most complex in the world. After all, it is something that needs to be delivered to the homes of 1.4 billion people across the country. Moreover, among China's huge population, there are only 4 million people without electricity. , compared to the nearly 100 million people in Asan next door who have no electricity, China can do this, and the total length of its transmission lines has reached about a quarter of the total length of the world's transmission lines.

Wires are basically made of copper, and a few lines also use aluminum. Obviously, these two materials have a certain resistivity at room temperature. Then recall the resistance formula, resistance = resistivity * conductor length / cross-sectional area.

Although China's long transmission lines are calculated in sections, the power loss caused by its resistance reaches more than 100 billion kilowatt-hours per year, which is more than the annual power generation of the Three Gorges Power Station.

Once the lines are replaced with room-temperature superconductors, these losses will become a thing of the past, and all substations can be eliminated. After the electric energy is generated from the power station, it is directly input into every household.

In addition, it can save a lot of power generation costs and buy a lot less coal imported from abroad every year.

As for the role of room temperature superconductors in other aspects, needless to say, superconducting energy storage equipment, particle collider, etc., including the research and development of quantum computers, can also use superconductors.

Thinking of this, Lin Xiao almost decided to exchange it directly.

However, he soon calmed down. This was 500 truth points, and it was still too expensive. There was no need to exchange it directly.

It would be better for him to study it first and then talk about it.

And he kept the truth in mind, thinking that if there is an emergency in the future, he would use it. If there is no emergency now, it is better to do some research on his own.

Zheng Cheng, who was standing next to him, saw the change in his expression and said, "Professor Lin, if you are really interested in superconductors, you might as well come to our laboratory sometime?"

After hearing Zheng Cheng's proposal, Lin Xiao thought for a while, then smiled and said, "Okay, I'm happy to go."

Compared with the National Condensed Matter Physics Laboratory, the relevant experimental equipment in his institute is somewhat lacking.

After all, it is a national laboratory. Although it is still under preparation and not fully completed, the national laboratory is still different from the national key laboratory. The status of the former is higher than that of the latter.

Seeing Lin Xiao agreeing, Zheng Cheng smiled and said: "Then I'm looking forward to your arrival. I believe our laboratory would also like to see you come. Do you want to come over and give a report or something?"

"That's a good suggestion." Lin Xiao smiled and said, "Don't say that I went to buy your experimental equipment for free."

Both of them laughed immediately.

…

By this time, the meal was almost done, so they didn't stay any longer and left the restaurant together.

Since Lin Xiao said he wanted to go to their condensed matter physics laboratory to have a look, he didn't waste any time. After returning, he directly contacted the person in charge of the laboratory, Fang Zhong.

Fang Zhong is an academician of the Academy of Sciences and the director of the Institute of Physics of the Chinese Academy of Sciences. Since the Condensed Matter Physics Laboratory also belongs to the Institute of Physics, he also serves as the director of the Condensed Matter Physics Laboratory.

When he learned that Lin Xiao was coming to communicate and planned to give a report, he couldn't help but feel pleasantly surprised.

Then he learned that the report Lin Xiao planned to give was about the theory of electronic topological bonding, which surprised him even more.

You must know that since Lin Xiao proposed the electronic topological bonding theory, he has not made any relevant reports. This time he came to them to report, but it was the first time!

So the Institute of Physics began to make intensive arrangements to prepare for Lin Xiao's arrival.

In this way, time passed quickly and came the day when Lin Xiao visited.
