It was half past nine the next morning.
Xiao Yi's dormitory door was knocked.
When I opened the door, I saw a young man standing outside, who seemed to be Physics Research Institute's graduate student.
"Scholar Xiao, hello! I am Teacher Pang's student. Teacher Pang asked me to come over and take you to the laboratory."
Xiao Yi nodded and said, "Okay, let's leave now."
Then he took his things and followed the graduate student to the laboratory.
On the way, he also met this graduate student named Xu Zhiqiang. He was a doctoral student and the senior disciple of Academician Pang Cheng. He was also the senior brother of the laboratory. As of September this year, he had been studying for a Ph. D. for almost 6 years.
"6 years?"
Xiao Yi was a little surprised.
Xu Zhiqiang shrugged. "No way, I'm a bad person."
"And Condensed Matter Physics, you know, it's really difficult to graduate."
"Instead of wasting time in uncharted areas, it's better to enjoy the time you have now."
As he said that, he took out his mobile phone and showed Xiao Yi the content on it. "Look, I recently looked at this question on Zhihu."
Xiao Yi took a look, and the question above was: [What is it like to have a useless doctor brother?]
Xu Zhiqiang said, "One thing to say, when I saw this problem today, I wondered if it was posted by juniors and juniors in our laboratory."
"But think about it, I'm pretty good to my junior brothers and sisters. Although I can't help them with research, I do treat them to meals in normal times. They shouldn't ask questions like this online."
"But, do you think this topic is annoying or not? Is there something we can't discuss offline? Isn't it good to ask their senior brother to treat them to a meal? It has to be at a black man's house online."
"It makes senior brothers like us panic."
As he said that, Xu Zhiqiang patted his chest, looking worried.
Xiao Yi: "... Well, I remember that a doctorate can last up to eight years, right? You should have prepared the topic now, right?"
"Hehe, we have to wait for my junior brothers and sisters, who will take care of senior brother then."
Xu Zhiqiang smiled shyly, "For the sake of how nice I am to them."
Xiao Yi couldn't help but shook his head in amusement and said, "But Condensed Matter Physics is a major, it's best to enter a graduate school after graduation, right?"
"Yes." Xu Zhiqiang nodded and said, "However, this probably has nothing to do with me. Obviously I am not born to eat this kind of rice."
"It's a pity." He sighed and said, "Since I can't become a great physicist, then I can only go home and inherit the family property after graduation."
Hearing the other party's sudden reversal, Xiao Yi was immediately stunned. "... What do you mean?"
Xu Zhiqiang shrugged, then pointed to a hotel building outside the Science Park and said, "Look, that hotel is under the name of my company, and there are hotels like this at my house... well..."
He smiled sheepishly, "Sorry, I can't remember clearly."
"I just said that I often invite my junior brothers and sisters to dinner, usually in that hotel, and it doesn't cost me any money anyway."
"Scholar Xiao, if you want to eat something good one day, just go over there and say my name and eat whatever you want."
Xiao Yi: "..."
Damn it, why is there anyone more Versailles than him?
Being able to open a hotel in this area is unimaginable just because of the land price, right?
"Okay, the experimental building is here."
At this time, Xu Zhiqiang's footsteps suddenly stopped.
At this time, they were already standing in front of a square building with red exterior walls.
There are several large gilded characters hanging on the upper left side of the front of the building.
[Shangjing Condensed Matter Physics Research Center].
As one of the most important directions in physics at the moment, Condensed Matter Physics also has an independent building in their Institute of Physics.
"It was originally planned to build a national laboratory, but in the end it was not completed and it became this Condensed Matter Physics research center."
While walking inside, Xu Zhiqiang introduced the past of their research center to Xiao Yi.
All in all, the specifications of their research center are ranked among the best in the country.
At the same time, they are considered to be the best in the world.
Comparing Institute of Physics of the Chinese Academy of Sciences with all physics research institutions in the world, Institute of Physics is also ranked in the top 5.
Xiao Yi also agreed with this.
Compared to Institute of Mathematics, Institute of Physics's status in the world is still relatively high.
Of course, the main reason is probably that physics research institutions often have relatively high funding requirements.
The more advanced the laboratory equipment, the easier it is to produce results.
This type of natural science research costs money.
As for mathematical research...
Needless to say.
After entering, you can also see that many people have come, and they all look like they are in a hurry.
Xu Zhiqiang couldn't help but sigh, "Oh, why do these people work so hard?"
"I don't even know how to enjoy myself."
Having said this, he turned to look at Xiao Yi and asked, "By the way, Scholar Xiao, do you want to take you to wash your feet or something tonight?"
Xiao Yi: "Uh..."
God is washing your feet. Is this senior brother serious?
At this moment, a hand reached out from behind and directly pushed Xu Zhiqiang's head to the side.
"What nonsense are you talking about here?"
An angry voice came from behind. Xiao Yi turned his head and saw Academician Pang Cheng, who didn't know when he appeared behind them.
Academician Pang pinched Xu Zhiqiang's ears. "It's useless. I just asked you to call Xiao Yi because you are the most idle person in the laboratory, but I didn't say that I asked you to say these things to Xiao Yi."
"You're still washing your feet. When you wash your feet one day, I'll just hit you up and persuade you to quit. Your father will really worry about you for nothing."
"Ah... it hurts, teacher, I was wrong! I was so wrong!"
Xu Zhiqiang grinned and begged for mercy.
"You worthless guy." Pang Cheng finally let go of his ears and snorted, "Don't let me hear you say these things to Xiao Yi in the future. Xiao Yi is not like you."
"Don't show off your wealth to Xiao Yi. As far as I know, Xiao Yi's current net worth should be several hundred million, right?"
Xu Zhiqiang rubbed his ears and was stunned when he heard Pang Cheng's words. What?
Xiao Yi's net worth is several hundred million?
Xiao Yi, on the other hand, looked confused. "Ah? Is there one?"
How many millions are there in his bank card?
Why doesn't he know?
Seeing Xiao Yi's expression, Academician Pang said, "Don't pretend you don't know. I've seen the news. Your Yishui Bit is now valued at 1 billion, right?"
Xiao Yi suddenly realized that this was what he was talking about.
Yishui Bit's current valuation is not 1 billion, only 700 to 800 million, but... the unit is US dollars.
This is mainly due to their Yishuibit, which now has more than three million permanent users, and the number of customers is still growing steadily.
The more than 3 million users seem to be very few compared to other software, but what you need to know is that these more than 3 million users are all paying users, and they are paying every second.
This alone is enough to significantly increase the valuation of the software.
It's just...
"The estimate is just an estimate. I don't have that much money in my pocket."
Xiao Yi said.
"Haha, that's not bad. None of the rich people on the list now calculate their net worth based on the estimated value."
Pang Cheng waved his hand and said nonchalantly.
"Okay, let's stop talking nonsense and take you to the laboratory first."
Then he walked in front, taking Xiao Yi towards the laboratory.
Xu Zhiqiang also quickly followed behind, looking at Xiao Yi in even more amazement.
He had never known before that Xiao Yi was actually a big boss worth over 100 million yuan.
This is even better than him, the rich second generation who inherited the family property.
At this time, he heard his teacher ask again, "By the way, I heard that you were rated Outstanding Young Scholar?"
Hearing this, he suddenly became even more confused.
ah?
Outstanding Young Scholar?
Real or fake?
Not Qingba?
Even if it is Excellent Young Scholar?
Why is it Outstanding Young Scholar?!
It must be that my teacher asked the question wrong, right?
As a result, he heard Xiao Yi reply, "Oh, Academician Pang, how did you know?"
Pang Cheng laughed, "The document was made public yesterday. It's hard not to see your name. Now there are many people in the circle discussing this matter."
Xu Zhiqiang, who was following behind, felt more and more that his perception was biased.
What the hell...
It's actually true?
His world view became messy.
All the way to the laboratory.
On the way, Pang Cheng also got a new white coat for Xiao Yi.
Wearing it on the body can be regarded as officially giving me the feeling of a researcher.
Soon, when I entered the laboratory, there were several people inside, probably a dozen or so, of course, mostly students.
"Come, let me introduce to you the new members of our research team."
Pang Cheng clapped his hands and shouted.
Soon, everyone in the laboratory looked over and looked at Xiao Yi with either curiosity or admiration, but there was also some jealousy mixed in.
Everyone has different thoughts about this genius who is already famous throughout Scientific Community at such a young age.
"This is Xiao Yi. I don't think I need to introduce him much. Let's not talk about his achievements in mathematics. The Absolute Electronic Computation method has brought us a lot of convenience, so you must not just treat Xiao Yi as a newcomer. Otherwise, if you make a fool of yourself, don't blame me for not telling you in advance."
Later, Pang Cheng introduced the members of his team to Xiao Yi.
There are a total of twelve people in this team. In addition to academician Pang Cheng, there are also two senior researchers, one named Guo Ding and the other named Cui Yuanhao.
Guo Ding looks to be about thirty-six or seven years old. He is mainly responsible for computing matters. He and Xiao Yi have quite a lot of topics. In addition to being a researcher of Physics Research Institute, he is also a researcher of Institute of High Energy Physics next door. After all, experts in the field of computational physics can still play a role in many aspects.
At the same time, Guo Ding seems to be someone who is easy to communicate with.
As for Cui Yuanhao, he is mainly engaged in Condensed Matter Physics. He is 40 years old this year. However, his attitude towards Xiao Yi is relatively cold, unlike others who are more or less enthusiastic.
Of course, it is normal to be enthusiastic or indifferent. After all, Xiao Yi is not RMB, so it is impossible for everyone to like him.
However, this Cui Yuanhao asked specifically, "I heard that you rated Outstanding Young Scholar?"
His question immediately made everyone present look surprised.
Because the document was only made public yesterday, it has not yet been widely circulated, but no matter what, this is also very impactful news.
In this regard, Xiao Yi did not deny it at the time, but nodded and accepted the matter.
However, Cui Yuanhao's next emotion seemed to be inadvertent, with some unclear intentions. "Outstanding Young Scholar in mathematics... the funds are wasted."
Of course, he quickly apologized and said, "Ahem, don't get me wrong, I just want to say that mathematics research does not require much funding. If this quota is allocated to physics or other majors, these funds can probably be fully utilized."
Pang Cheng didn't care what Cui Yuanhao wanted to express. As the director and an academician, he immediately reprimanded directly. "Cui Yuanhao, don't talk nonsense here. The quota for outstanding youths is calculated based on the contribution of others. If it is not given to Xiao Yi, it will be difficult." Not for you? You haven't been selected as an outstanding student yet. Think more about the results you have made. The institute applied for more than one million yuan in funding for your project, but you don't know what the results are. "
Cui Yuanhao's face darkened, but he didn't dare to say anything in front of Academician Pang, so he quickly apologized and left quickly.
Pang Cheng patted Xiao Yi on the shoulder and said, "Don't worry about that person. He has a mental problem."
"Professor Guo, I will leave it to you to explain the details of our project to Xiao Yi. Didn't you always say that it would be great if Xiao Yi could come to our research team? Now I have brought people over for you."
Guo Ding laughed and said, "Okay, just leave it to me. Academician Pang Just don't worry."
Pang Cheng nodded, and then said to the others, "Okay, let's go do the experiments, don't look here."
The remaining people are basically postdocs and graduate students, commonly known as part-time workers.
Hearing Pang Cheng's words, they all felt a little regretful that they couldn't get the melon.
Academician Pang It is rare to reprimand a researcher.
Soon, Xiao Yi and Guo Ding came to the side.
As for what happened just now, Guo Ding said, "Lao Cui, how should I put it, is a bit impatient and has a bad mentality."
"It's probably because the people who were in the same group with him have already rated Outstanding Young Scholar, but he hasn't rated it yet, so he's a bit sensitive, so don't worry about it."
Xiao Yi shook his head. "No way."
Director Liu Cong also told him that some people would have objections, so he also expected it, but what he didn't expect was that he would meet one so soon.
"That's fine."
Guo Ding nodded, and then said with a smile, "I have wanted to communicate with you for a long time, and now I have finally waited. Regarding your Absolute Electronic Computation, I have many questions that I want to ask you about."
"However, it is still working time now, so I will explain our topic to you first."
Then, Guo Ding explained their current research progress on this topic to Xiao Yi.
"It mainly involves the parent compound of FeSe/SrTiO3 single-layer superconductor."
"You should know that high-temperature superconductors can be realized by doping their parent compounds, so studying the parent compound and the parent-superconductor transformation has a good chance of yielding results in understanding the superconducting mechanism."
"Parent compounds such as copper oxide are usually antiferromagnetic Mott insulators, while parent compounds of iron-arsenic-based superconductors mostly exhibit antiferromagnetic ordered metallic behavior."
"The one we studied, the FeSe superconductor, has the simplest chemical and crystal structure. Fe4Se5 with ordered iron vacancies is considered to be the parent compound of the FeSe superconducting bulk."
"However, no one has ever mentioned the iron vacancy sequence matrix compound of FeSe/SrTiO3 single-layer superconductor, so our purpose is to start from this aspect to help us understand the mechanism of high-temperature superconductivity."
"Now our research group is stuck on a major problem. It is generally believed in the academic community that due to the strong interfacial coupling interaction, it is impossible to form an ordered state of iron vacancies in a single layer of FeSe/SrTiO3. How to experimentally achieve an ordered FeSe monolayer with iron vacancies will test our design."
"Just realizing this is worth a PRL."
Listening to the other party's introduction, Xiao Yi nodded slightly.
In fact, he has read many papers in this area during this period, so he is relatively familiar with research in related fields.
It is estimated that if he writes a review, he can send it to the review pages of some top journals.
After a brief introduction, Guo Ding handed a lot of experimental information to Xiao Yi: "Look, these are some of our current images, data and the like. You can get to know them first."
"Afterwards, we are trying to use computational simulations to help them analyze the situation and see if we can find a way for them to introduce iron vacancy defects in FeSe/SrTiO3 single-layer superconductors."
Xiao Yi took the data and started reading it.
Guo Ding didn't say anything anymore. He walked to the computer aside and began to study the model.
Time passed quickly.
About an hour later, Guo Ding noticed that Xiao Yi came to his side and put the information on the table.
"Have you finished reading?"
"Well, I've finished reading."
Xiao Yi nodded.
"Okay, then let's..."
Just when Guo Ding was about to explain their work, Xiao Yi continued to speak and interrupted him.
"I looked at the experimental data in detail. In addition, I also thought about some papers in this area during this period. I have some ideas about the method of our experiment."
"You said, can we use hydrogen to promote atomic migration and defect formation in FeSe/SrTiO3 single-layer superconductors?"
"The specific principle is the high diffusivity and chemical activity of hydrogen atoms..."
Guo Ding was stunned and said blankly, "What?"
He is only an expert in computational physics and is by no means proficient in experimental physics.
But at this moment, Pang Cheng came to them out of nowhere and said in a deep voice, "Keep talking."
Xiao Yi was startled and turned to look at Pang Cheng.
This Academician Pang seems to be a bit good at approaching others quietly.
However, he continued, "Well, to put it simply, it is a kind of Hydrogen Power Method..."
"Under high temperature conditions, hydrogen gas decomposes into active hydrogen atoms, and then the hydrogen atoms diffuse inside the material and penetrate into the crystal lattice of the material. Then the hydrogen atoms interact with the metal atoms in the material, such as the iron atoms in our FeSe/SrTiO3 single-layer superconductor, reducing the migration energy barrier of these atoms."
"The lowered energy barrier will make it easier for metal atoms to migrate, forming vacancies or other types of defects."
"In this way, will we have a chance to realize iron vacancy defects in FeSe/SrTiO3 single-layer superconductors?"
Xiao Yi's words made Pang Cheng fall into thinking.
Until a moment later, he took a deep look at Xiao Yi and said, "It seems that inviting you to join is definitely the most correct choice I have ever made."
"The method you mentioned has great potential!"
