Regardless of how other countries are struggling to restart manned spaceflight and lunar exploration projects for China, Xu Chuan is immersed in his own world.
From the perspective of quantum chemistry, the strong diamagnetic mechanism in KL-66 material is explained.
It has to be said that when the traditional condensed matter theory lost its effectiveness, quantum theory played an unexpected role at this time.
However, for now, this is just a new road, and Xu Chuan is not sure whether it will work.
...
Late at night, in the Beihai Hotel, Xu Chuan tidied the manuscript papers on the table, then got up and went to wash up.
If it were normal times, he would probably stay up for a while longer and study it.
But today I have promised Mr. Pan to go to Peking University to chat with him tomorrow, so I will just rest early.
After all, the elderly sleep for shorter periods of time, so they should have more energy in the morning.
The next day, early morning.
Xu Chuan got up early, stretched out his body, had breakfast, and then headed to Peking University.
I successfully passed the security to find the professor's residential area, where old academician Pan Deming was currently exercising his muscles in the community.
"Mr. Pan, good morning." After looking at it for a while, Xu Chuan stepped forward and said hello with a smile.
Hearing the sound, the old academician Pan Deming, who was doing Tai Chi, turned his head and looked over, with a smile on his face and said: "Good morning, have you had breakfast?"
"After eating, how is your recovery, Mr. Pan?" Xu Chuan smiled and gave some tea leaves he brought to the old academician in front of him, and asked with concern.
"tea?"
Pan Deming curiously took the box, looked at it, smelled it, and then said with a smile: "This tea is of good quality. Where did you get it?"
Xu Chuan smiled and said: "The elder gave it to me. I don't know what kind it is. Yesterday during the meeting, he asked Chief Qin to bring it to me. I think you are not short of anything to eat and drink.
I borrowed flowers to offer to the Buddha and brought a box over."
Hearing this, the old academician Pan Deming was stunned for a moment, and then said with a smile: "That emotion is a good thing, so I accepted it."
Xu Chuan smiled and said, "As long as Mr. Pan likes it."
Pan Deming laughed and said: "Speaking of tea, I was able to get two boxes of good tea from Mr. Qin in the past two years. Maybe it was because I had made too much tea in the autumn wind, so he hid it and refused to give it to me.
Already."
"Come on, come on, let's sit in the room first. Do you have time today? Have lunch before you leave? Can you have a drink with me at noon?"
Xu Chuan smiled and said: "You have to pay attention to your health. Drink as little as possible."
Pan Deming took Xu Chuan into the room and said with a smile: "Hey, it's rare to be happy, so don't say such things."
After a slight pause, he continued: "I heard that we are going to build a large strong particle collider?"
Xu Chuan nodded and said: "Well, it is indeed a request. The relevant instructions have been issued. There will be a related discussion meeting at the Science and Technology Center next Thursday."
Pan Deming smiled, looked at Xu Chuan and said, "It's a good thing. It is still necessary to build such scientific facilities."
"It's just that you are so busy here? You are involved in the manned space project, the collider, and you also have to control the Xinghai Research Institute. Do you have enough energy?"
Xu Chuan smiled and said: "It depends on how to use it."
After a pause, he continued: "For me, management work has never been the focus. I prefer to lead the team to solve technical problems."
"Just like when we were researching controllable nuclear fusion, the daily management work was basically handled by Peng Hongxi, Peng Lao and Gao Hongming, and I could just concentrate on overcoming technical problems."
Pan Deming smiled and said: "You really don't care about these things at all. The position of chief designer and chief designer of controllable nuclear fusion has been relinquished."
As he said this, he looked at Xu Chuan, licked his lips, and shook his head with a smile.
To be honest, if the position of chief designer and general person in charge of controllable nuclear fusion is given to someone else, even if it is given to him, he may not be so determined to quit it directly.
After all, there will be second-generation controllable nuclear fusion, fusion energy companies and other developments in the future. As long as he sits in that position, his right to speak is unshakable.
But the young man in front of him, after the demonstration pile was successfully ignited, turned around and left as if he had completed his mission.
Xu Chuan smiled and said: "What I do is actually just what a scholar and a scientific researcher should do."
Pan Deming smiled and said curiously: "Speaking of which, do you still have time and energy to study mathematics?"
"Now that you have made various developments in other fields, you are almost turning into an applied scholar. Are you still doing theoretical research?"
Hearing this question, Xu Chuan said with a smile: "Of course, application and theory are on parallel tracks. No matter which one is deviated from, the train of scientific research will be derailed."
"In the past two years, I did relatively little research on controllable nuclear fusion engineering, but I still have to pick it up after all."
After a pause, he continued: "Actually, I have been studying some theoretical things recently, but there is not much progress so far."
Hearing this, Pan Deming looked over curiously and asked: "Which one? Mathematics or physics?"
"It's both aspects, mainly the strongly correlated electronic system."
Xu Chuan smiled and replied: "When I was studying KL-66 materials from South Korea, I made some unexpected discoveries. I am trying to see if I can explain it through mathematics."
"If it succeeds, the theory of strongly correlated electron systems should be able to make some breakthroughs. However, it is still being explored and it will be very difficult to make a breakthrough."
For the old academician in front of him, he didn't mind revealing his research direction and scope.
After all, if he can no longer be trusted, there will be no trustworthy person in this world.
Hearing this, Pan Deming looked a little moved. He said: "This should be a worldwide problem. The condensed matter physics community has been studying it for many years."
Xu Chuan nodded and said, "Well, you can put it this way."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "This research is actually mainly for superconducting materials. Subsequent research in aerospace engineering and controllable nuclear fusion will require the use of high criticality
Superconducting materials for magnetic fields.”
"If there is a breakthrough in this theory, it may be possible to increase the critical magnetic field of superconducting materials by an order of magnitude."
Pan Deming thought for a while and said: "I don't know much about strongly correlated systems, but maybe you can talk to Yang Zhenhuan? His research in condensed matter physics is quite unique."
Xu Chuan smiled and said: "Old Yang will be a hundred years old next year, and he is already ninety-nine this year. It is not appropriate to nag him again."
Hearing this, the old academician Pan Deming sighed and said: "There are many scholars in the country, and there are also many engaged in mathematics and condensed matter physics, but only a few can reach the top of the world. Otherwise, there will be no one to talk to."
Questions to talk about.”
"Since you, the gap between top scholars has been too serious. No, it should be said that you have brought domestic mathematics and physics to a whole new level, and this problem has only appeared."
The two seven-millennium problems can be said to be a towering mountain that is unattainable to the Chinese mathematics community.
For a mathematician of this young caliber in front of me, looking at the entire country of China, Mr. Qiu, who returned from the United States, is probably the only one alive today who can enter this field.
Maybe Mr. Yang, who is engaged in physics, can count half of it, but after all, he is not a person in the field of mathematics.
Others, such as Zhang Yitang, the golden generation of Peking University, Li Jun of Fudan University, and others are still far behind compared to the one in front of me and Mr. Qiu.
Xu Chuan smiled and was about to open his mouth to speak. In the living room, two old people walked in accompanied by a middle-aged woman.
Seeing the person coming, Xu Chuan was stunned for a moment, with a trace of surprise in his eyes.
The old man walking in front was none other than Mr. Yang, whom he and Academician Pan were chatting with just now, and the middle-aged woman next to him was undoubtedly his ex-wife, Ms. Weng, and she was holding a fruit basket in her hand.
.
And standing a little behind was Mr. Qiu.
These two people came together, which really surprised Xu Chuan.
After all, this is Peking University, and both Qiu and Yang are in Shuimu.
Of course, it's not that far apart. It's just a street away, so you can just stroll there.
In the living room, Mr. Qiu, who was walking behind, had sharp eyes. He immediately saw Xu Chuan sitting on the sofa and greeted him with a smile: "Hey, Academician Xu, what a coincidence. I didn't expect you to be here."
Here too?"
Hearing this voice, Mr. Yang, who was walking ahead, squinted his eyes and recognized Xu Chuan.
Xu Chuan stood up with a smile and said hello to the two old men: "Mr. Qiu, Mr. Yang, I didn't expect to meet you two here."
Qiu Chengtong smiled and said: "It's not the old guy Pan Deming. He was lying there in the hospital for more than a month some time ago, causing people to worry. After he was discharged from the hospital, Lao Yang and I came over to take a look. Don't let this old guy leave.
It’s ahead of us.”
"But looking at him today, he should be recovering well."
For Qiu, although he has an incomprehensible relationship with the Department of Mathematics of Peking University, that is another matter and does not affect his friendship with Academician Pan.
After all, the two are almost the same generation and can be said to have been friends for many years.
Hearing this, Pan Deming immediately blew his beard and stared, looking over: "You old guy, how can you talk? I won't leave even if you leave!"
Qiu Chengtong ignored him, looked at Xu Chuan with a smile, and asked, "Speaking of which, why are you here?"
Hearing the sharp 'quarrel' between Qiu Chengtong and Pan Deming, Xu Chuan twitched the corner of his mouth a few times and replied: "Didn't Shuimu hold a meeting on the manned space project yesterday? I came here to attend the meeting. Then he
Come and sit."
Qiu Chengtong raised his eyebrows and said with a smile: "It seems that you and this old guy have known each other quite early."
Xu Chuan coughed lightly and said, "We have indeed known each other for a while."
On the side, Mr. Yang sat down with the support of Ms. Weng and looked Xu Chuan up and down.
This was the first time the two met, and they had never met before.
After all, when Xu Chuan came back in 2018, he was already 96 years old and had already retired.
But they must know each other, or at least know each other.
After staring at Xu Chuan for a while, Mr. Yang sighed: "The first time I heard your name, it was from astronomy."
"If I remember correctly, it seems to have been 15 years. At that time, your observations and calculations of Betelgeuse shocked the entire astronomy and astrophysics world."
"I didn't expect that only three years later, you would win the Nobel Prize in Physics and solve the problem of controllable nuclear fusion technology. Your future life will be formidable."
Xu Chuan smiled and said, "I've always wanted to visit you, but I was very busy at work and couldn't spare the time."
Mr. Yang waved his hand and said: "I originally planned to chat with you at the collider seminar a week later, but I didn't expect to meet you in advance today. It's a fate."
After a slight pause, he glanced at Xu Chuan and asked curiously: "How are you doing with your research on sterile neutrinos and dark matter?"
Xu Chuan thought for a moment and said: "Research in this area can only be said to have directions and ideas. For specific situations, we must conduct experiments through collider, verify calculations, collect data and analyze."
"Are you sure?" Mr. Yang asked.
Xu Chuan smiled and said: "When it comes to research, no one dares to say that they are 100% sure to do it until the facts have settled."
After a pause, he looked at Academician Yang and said with a smile: "But I am still more or less certain, but I don't know how many difficulties we will encounter in the process."
Hearing this, Mr. Yang stared at him for a while and was silent for a long time before he said: "In the past few decades, whenever the country discusses the construction of a large strong particle collider, I have publicly stood up and written articles.
Those who oppose it will directly delay the construction of the collider."
"I think it is totally not worth spending 200 billion to build a collider. After all, we are still in the process of development and there are more places where money is needed."
"And we lack high-level physics talents. The number is not even 1% of the world's physics researchers. Even if the collider is built, how many of us will be able to make full use of it?"
"Including 2016, even though the country was able to build it at that time, I still think it is a project that wastes people and money."
"For this reason, I almost fell out with the entire domestic physics field."
"I know that my colleagues are very dissatisfied with me and say that I want to shut down their industry. But this collider will cost 200 billion, and the follow-up will be even more. I don't think I can accept this.
"
Hearing this, Xu Chuan smiled and asked, "So Mr. Yang wants to persuade me to take it easy today?"
He knew that this man had always been opposed to building a collider, but he didn't expect that this old gentleman seemed to want to convince him when they met for the first time today?
