The top student must be diligent.

Chapter 159 A small test of one’s skills
The next morning at 9:30.

There was a knock on Xiao Yi's dormitory door.

When I opened the door, I saw a young man standing outside. He seemed to be a graduate student at the Institute of Physics.

"Hello, Xiao Shen! I am Teacher Pang's student. Teacher Pang asked me to come and take you to the laboratory."

Xiao Yi nodded and said, "Okay, let's go now."

Then he packed his things and followed the graduate student to the laboratory.

On the way, he also met this graduate student, named Xu Zhiqiang, a doctoral student, a senior disciple under Academician Pang Cheng, and the eldest brother in the laboratory. As of September this year, he had been studying for a doctorate for almost 6 years.

"Year 6?"

Xiao Yi was a little surprised.

Xu Zhiqiang shrugged: "I can't help it. I'm a bad person."

"And as you know, condensed matter physics is really hard to graduate from."

“Instead of wasting time on unknown things, it is better to enjoy the present moment.”

As he said that, he took out his cell phone and showed Xiao Yi the content on it: "Look, I've been reading this question on Bihu recently."

Xiao Yi took a look and the question was: [What is it like to have a useless PhD brother? ]

Xu Zhiqiang said: "To be honest, when I saw this question today, I wondered if it was sent by a fellow student in our lab."

"But think about it, I'm pretty good to my fellow juniors. Although I can't help them with research, I usually treat them to meals. They shouldn't ask this kind of question online."

"But, do you think the thread starter is annoying? Can't we discuss this offline? Can't we ask their senior brother to treat them to a meal? Why do they have to slander him online?"

"It makes us, the senior brothers, panic."

As he spoke, Xu Zhiqiang patted his chest, looking frightened.

Xiao Yi: "... Well, I remember that a doctorate takes at most eight years, right? You should have prepared your research topic by now, right?"

"Hehe, I'll have to wait for my fellow junior brothers and sisters to guide my senior brother when the time comes."

Xu Zhiqiang smiled shyly: "Because I'm usually so nice to them."

Xiao Yi couldn't help but shook his head in amusement and said, "But for condensed matter physics majors, it would be best to go to graduate school after graduation, right?"

"Yeah." Xu Zhiqiang nodded and said, "But this probably has nothing to do with me. Obviously, I am not born to do this."

"What a pity." He sighed and said, "Since I can't become a great physicist, I can only go home and inherit the family property after graduation."

Hearing the other party's sudden reversal, Xiao Yi was stunned: "...What do you mean?"

Xu Zhiqiang shrugged, then pointed to a hotel building outside the Science Park and said, "Look, that hotel is owned by my company, and my family also has hotels like this... um..."

He smiled sheepishly: "Sorry, I can't remember clearly."

"I just said that I often treat my junior brothers and sisters to dinner, usually in that hotel. Anyway, it doesn't cost me money."

"Xiao Shen, if you want to eat something good someday, just go over there. Tell me your name and you can eat as much as you want."

Xiao Yi: “…”

Damn, how could there be someone more Versailles than him?
Being able to open a hotel in this place, the land price alone is unimaginable, right?
"Okay, we've arrived at the lab building."

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 gold-plated characters hanging on the upper left side of the front of the building.

[Shanghai Condensed Matter Physics Research Center].

Condensed matter physics, as one of the most important directions in physics today, also has an independent building in their Institute of Physics.

“Originally, it was planned to build a national laboratory, but it was not built, so it became this condensed matter physics research center.”

As they walked inside, Xu Zhiqiang introduced the past of their research center to Xiao Yi.

All in all, the standards of their research center are among the best in the country.

At the same time, they are considered to be top-notch in the world.

If we compare the Institute of Physics of HUST with all the physics research institutions in the world, we can rank it among the top 5.

Xiao Yi also agreed with this.

Compared with the Institute of Mathematics, the Institute of Physics has a relatively high status in the world.

Of course, probably the main reason is that physics research institutions often have higher funding requirements.

The more advanced the laboratory equipment is, the easier it is to produce results.

This kind of natural science research costs a lot of money.

As for mathematical research...

Needless to say.

After entering, I could see that quite a few people had arrived, and they all looked hurried.

Xu Zhiqiang couldn't help but sigh: "Ah, why are these people working so hard?"

“They don’t even know how to enjoy themselves.”

At this point, he turned to look at Xiao Yi and asked, "By the way, Xiao Shen, do you want me to take you to wash your feet or something tonight?"

Xiao Yi: "Uh..."

What the hell, is this senior brother serious about washing feet?

At this moment, a hand reached out from behind and pushed Xu Zhiqiang's head aside.

"What the hell are you talking about here?"

An angry voice came from behind. Xiao Yi turned around and saw Academician Pang Cheng, who had appeared behind them at some point.

Academician Pang pinched Xu Zhiqiang's ear and said, "Useless thing, I asked you to call Xiao Yi over because you are the most idle person in the lab, but I didn't say that I asked you to say these things to Xiao Yi."

"Washing feet? One day when you wash your feet, I will call you and persuade you to quit. Your dad is really worrying about you for nothing."

"Ah...it hurts, Teacher, I was wrong! I was so wrong!"

Xu Zhiqiang gritted his teeth and begged for mercy.

"You useless fellow." Pang Cheng finally let go of his ear and snorted, "Don't let me hear you telling Xiao Yi these things in the future. Xiao Yi is not the same as you."

"Don't show off your property 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?

How many hundreds of millions is Xiao Yi worth?

Xiao Yi looked confused: "Ah? Is there?"

How many hundreds of millions are in his bank card?
Why doesn't he know?
Academician Pang saw Xiao Yi's expression and said, "Don't pretend you don't know. I've read the news. Your Yishui Bit is now estimated to be worth 10 billion, right?"

Xiao Yi suddenly realized that this was what he was talking about.

The current estimated value of Yishui Bit is not 10 billion, but only about or million, but... the unit is US dollars.

This is mainly due to the fact that Yishui Bit now has more than three million regular users, and the number of customers is still growing steadily.

More than 300 million users may seem very small compared to other software, but you must know that these more than 300 million users are all paying users, and they are paying fees every second.
This alone is enough to significantly increase the software's valuation.

only……

"The valuation is just an valuation. I don't have that much money in my pocket."

Xiao Yi said.

"Haha, that doesn't matter. All the wealthy people on the list now have their wealth calculated 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 and took Xiao Yi towards the laboratory.

Xu Zhiqiang quickly followed behind, looking at Xiao Yi with amazement.

He had never known before that Xiao Yi was actually a big boss with a net worth of over 100 million.

This is much more impressive than him, the rich second generation who inherited the family fortune.

At this time, he heard his teacher ask again: "By the way, I heard that you were selected as an outstanding young scholar?"

Hearing this, he became even more confused.

what?
Outstanding Youth?

real or fake?

Not Qingba? Even if it is Youqing?
Why is it so outstanding? !
Maybe my teacher asked the wrong question?

As a result, he heard Xiao Yi answer: "Hey, Academician Pang, how did you know?"

Pang Cheng laughed: "The document was made public yesterday. It's hard not to see your name. Many people in the circle are discussing this matter now."

Xu Zhiqiang, who was following behind, felt more and more that there was a deviation in his cognition.

What the hell...

Is it true?
His worldview became chaotic.

……

All the way to the laboratory.

On the way, Pang Cheng also got Xiao Yi a new white coat.

When I put it on, I officially feel like a researcher.

Soon, we entered the laboratory. There were several people inside, about a dozen or so, and of course, most of them were students.

"Come, let me introduce to you the new members of our research group."

Pang Cheng clapped his hands and shouted.

Soon, everyone in the laboratory looked over and cast glances of curiosity or admiration at Xiao Yi, but there were also some jealous looks.

Everyone has different thoughts about this genius who has already gained such a great reputation in the entire scientific community at such a young age.

"This is Xiao Yi. I don't think I need to introduce him in detail. Let's not talk about his achievements in mathematics. The absolute electronic calculation method has brought us a lot of convenience. So you must not just regard Xiao Yi as a newcomer. Otherwise, don't blame me for not telling you in advance if you make a fool of yourself."

Afterwards, Pang Cheng introduced the members of his team to Xiao Yi.

The team consists of twelve people in total. In addition to Academician Pang Cheng, there are two senior researchers, one named Guo Ding and the other named Cui Yuanhao.

Guo Ding looks to be about thirty-six or thirty-seven years old. He is mainly responsible for computing matters. He and Xiao Yi have quite a lot to talk about. In addition to being a researcher at the Institute of Physics, he is also a researcher at the Institute of High Energy Physics next door. After all, as an expert in the field of computational physics, he 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 rather cold, unlike other people who seem more or less enthusiastic.

Of course, it is normal to be enthusiastic or cold. After all, Xiao Yi is not a RMB, and it is impossible for everyone to like him.

However, Cui Yuanhao specifically asked, "I heard that you were selected as an 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, it is also a very shocking news.

In this regard, Xiao Yi did not deny it and nodded to agree to it.

However, Cui Yuanhao's next sigh seemed to be inadvertent, and the intention was a little unclear: "The funding for the Young Elite Scientists in Mathematics is a waste."

Of course, he quickly apologized and said, "Ahem, don't get me wrong. I just want to say that mathematics research doesn't require much funding. If this quota is placed in physics or other majors, the funds can probably be put to good use."

Pang Cheng didn't care what Cui Yuanhao wanted to say. As the director and also an academician, he immediately reprimanded him, "Cui Yuanhao, don't talk nonsense here. The number of outstanding young scientists is calculated based on people's contributions. If it's not given to Xiao Yi, how can it be given to you? You haven't been rated as an outstanding young scientist yet. Think more about your own achievements. The institute applied for more than one million yuan in funding for your project. What kind of results did you produce in the end? Don't you have any idea? Do your experiment."

Cui Yuanhao's face turned dark, 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 problem with his mentality."

"Professor Guo, I'll 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 group? Now I've brought him here for you."

Guo Ding laughed and said, "Okay, leave it to me. Academician Pang, just rest assured."

Pang Cheng nodded, and then said to the others: "Okay, go do the experiment, don't just watch here."

The rest of the people are basically postdoctoral fellows and graduate students, commonly known as workers.

After hearing Pang Cheng's words, they all felt a little regretful that they couldn't eat the melon.

It is rare for Academician Pang to scold a researcher.

……

Soon, Xiao Yi and Guo Ding came over.

As for what happened just now, Guo Ding said: "How should I put it, Lao Cui is a bit impatient and has a bad mentality."

"It's probably because the people who were in the same group with him have been selected as outstanding young scientists, but he himself has not been selected yet, so he is a little sensitive. You don't have to worry about it."

Xiao Yi shook his head: "That won't happen."

Director Liu Cong had told him at the beginning that some people would have objections, so he had anticipated this. However, he did not expect to encounter one so soon.

"That's fine."

Guo Ding nodded, then smiled and said, "I have wanted to communicate with you for a long time, and now I have finally waited for it. Regarding your absolute electronic calculation, I have a lot of questions I want to ask you."

"However, it's still working hours, so I'll explain our topic to you first."

Then, Guo Ding explained to Xiao Yi the research progress of their current topic.

"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 compounds and the parent-superconductor transition is very fruitful in understanding the superconductivity mechanism."

"For example, the parent compounds of cuprates are usually antiferromagnetic Mott insulators, while the parent compounds of iron-arsenic-based superconductors mostly exhibit antiferromagnetic ordered metallic behavior."

"The FeSe superconductor we studied has the simplest chemical and crystal structure, and the iron-vacancy ordered Fe4Se5 is considered to be the parent compound of the FeSe superconducting bulk."

"However, no one has ever mentioned the iron-vacancy order parent compound of FeSe/SrTiO3 monolayer superconductors, so our goal 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. The academic community generally believes that due to the strong interface coupling interaction, it is impossible to form an ordered state of iron vacancies in a single layer of FeSe/SrTiO3. How to experimentally realize an ordered FeSe monolayer with iron vacancies is a great challenge for our design."

"Just achieving this is worth publishing a PRL."

Listening to the other party's introduction, Xiao Yi nodded slightly.

In fact, he has read a lot of papers on this subject during this period, so he is relatively familiar with research in related fields.

I guess any review he writes can be sent to the review page of some top journals.

After a brief introduction, Guo Ding handed a lot of experimental materials to Xiao Yi: "Take a look, these are some of our current images, data and the like. You can take a look at them for now."

"After that, we are trying to use computational simulation to help them analyze the situation and see if we can find a way to introduce iron vacancy defects into the FeSe/SrTiO3 monolayer superconductor."

Xiao Yi took the data and started looking at it.

Guo Ding didn't say anything else. He walked to the computer and began to study the model.

Time passed quickly.

About an hour later, Guo Ding noticed that Xiao Yi walked to his side and placed the information on the table.

"Have you finished reading?"

"Well, it's over."

Xiao Yi nodded.

"Well, then we will..."

Just as Guo Ding was about to explain their work, Xiao Yi continued speaking and interrupted him.

"I took a closer look at the experimental data. In addition, I also read some papers I've been thinking about recently. 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 monolayer superconductors?"

"The specific principle is the high diffusivity and chemical activity of hydrogen atoms..."

Guo Ding was stunned and asked blankly: "What?"

He is just an expert in computational physics and is not proficient in experimental physics.

But at this moment, Pang Cheng came to their side and said in a deep voice: "Go on."

Xiao Yi was stunned and turned to look at Pang Cheng.

It seems that Academician Pang is quite good at approaching others quietly.

However, he continued: "Well, in simple terms, it is a hydrogen-powered method..."

"Under high temperature conditions, hydrogen decomposes into active hydrogen atoms, which then diffuse inside the material and penetrate into the material's crystal lattice. The hydrogen atoms then interact with the metal atoms in the material, such as the iron atoms in our FeSe/SrTiO3 single-layer superconductor, to reduce 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, do we have a chance to realize iron vacancy defects in FeSe/SrTiO3 monolayer superconductors?"

Xiao Yi's words made Pang Cheng fall into deep thought.

After a moment, he looked at Xiao Yi deeply and said, "It seems that inviting you to join is definitely the best decision I have ever made."

"The method you mentioned has great potential!"
