Chapter 147 I finally published a paper

Xu You had never thought before that before learning how to use a piece of equipment, he had to learn the fault conditions first.

But since this is a piece of equipment whose failure time is longer than the normal state time, it is also very necessary to understand various failure problems first.

"In fact, the main faults all occur in the vacuum system, which is also a kind of fault that is difficult to avoid in this kind of equipment. This kind of fault can usually be rectified in one day, repaired in half a day, and takes a few more days to dry.

Bake it, remove the gas, and reach the ideal vacuum environment, then you can continue to use it.”

"Of course, if a fault occurs, such as a screw being screwed off or water or air leaking somewhere, the troubleshooting may take longer."

Listening to Cao Quanli's words, Xu You also understood the key points.

That is, when the ARPES device is normal, you must quickly create a few more sets of data.

To avoid equipment failure, time will be wasted waiting for baking and degassing.

Through Cao Quanli's introduction, Xu You knew that Jida's ARPES equipment was considered one of the more advanced equipment of its kind.

This ARPES equipment can use the flight time of electrons to measure the energy of electrons.

This allows the detector to simultaneously measure the electronic information of the entire surface in the two-dimensional momentum space.

Compared with most energy spectrometers that use one-dimensional momentum detection, the momentum detection efficiency is improved by at least two orders of magnitude.

After understanding how to use the equipment, Xu You started his own experiment.

First, Xu You needs to measure various high-temperature superconductors to obtain their crystal structures, energy band structures and other data to analyze their superconducting mechanisms.

During the course of the experiment, it was not as exaggerated as Cao Quanli said, and the equipment was in a state of repair for a long time.

Of course, ARPES equipment is still prone to failure.

Xu You spends a lot of his energy on repairing equipment.

However, Xu You did not feel bothered by this.

After all, repairing equipment itself is also part of scientific research work.

While the equipment is in the baking state, Xu You can also sort out the data with peace of mind, study the crystal structure, energy band structure and other characteristics of various high-temperature superconductors, and summarize some rules from them.

Xu You himself still likes this state very much.

After a stage of experiments, Xu You has completed ARPES analysis of various high-temperature superconductors, and summarized some new experiences that have not been summarized by predecessors.

Xu You also communicated with Qiao Sen immediately.

"Teacher, even for the same Fermi surface, cuprate high-temperature superconductors and iron-based superconductors may contain different orbital properties. There are such differences in their electronic structures."

Looking at Xu You's recent research results, Qiao Sen nodded repeatedly.

Although there is still a long way to go before perfecting the mechanism of high-temperature superconductors.

But at least it has taken another step towards explaining the mechanism of high-temperature superconductivity.

"Yes, this theory is already groundbreaking. How about it, how does it feel to do the project independently?"

"It's still very challenging. Especially the ARPES equipment. I feel like I'm already a professional repairman."

Hearing this, Qiao Sen couldn't help laughing.

"No way, this kind of equipment is very delicate. But if you want to study in this area, the ARPES experiment is also indispensable. OK, you can continue. If you have any latest progress or encounter any problems, you can contact us directly.

I."

To be honest, Qiao Sen did not expect Xu You to make some breakthrough progress so quickly.

If this momentum continues, even if Xu You really understands the mechanism of high-temperature superconductors, it will not be impossible.

After these days of hard scientific research work, Xu You somewhat neglected relaxing activities.

The fatigue level of the system interface has accumulated to close to the upper limit.

It happened that Lou Song asked Xu You to play ball, and Xu You decisively agreed.

Because Xu You has been neglecting exercise recently, Xu You's skills have declined instead of improving, and he was even more abused by Lou Song.

However, Xu You doesn't attach much importance to victory or defeat. As long as he can achieve the purpose of relaxation through exercise, it is the greatest success.

After playing ball, Lou Song took out a book from his schoolbag and mysteriously handed it to Xu You.

Xu You took it and took a look and found that it was a journal.

"This is...Annals of Mathematics?"

Soon, Xu You recognized the origin of this journal.

Annals of Mathematics is one of the four major journals in the field of mathematics.

For most mathematicians, it is very difficult to publish a paper in the four major journals.

Thinking of what Lou Song had said before, Xu You probably guessed why Lou Song gave him such a journal.

"Did you publish a paper on it?"

"Hey, you'll know just by looking at it."

Seeing Lou Song's mysterious look, Xu You simply opened the journal by himself.

Sure enough, on a certain page in the journal, Xu You saw a paper from Ji Dasong.

"Awesome! You are only 16 years old and you can publish papers in four major journals! Now you are not far away from the Fields Medal, right?"

"I'm not as good as you. I'm still a freshman, and you've published so many papers. I'm still far from winning the Fields Medal, but I will work hard in this direction."

At this time, Xu You was also really happy for Lou Song.

Xu You carefully received this journal into his bag and decided to go back and treasure it together with the journals he distributed.

"By the way, let me tell you something. In my sophomore year, I am going to the Princeton Mathematics Department for a year, and the procedures have been completed."

Hearing the news, Xu You was not too surprised.

"Very good. This is indeed a good opportunity. Have you already passed the TOEFL?"

"Well! I have been preparing for this, so I have finished the exam a long time ago."

"Awesome. I just finished CET-4, and my English is far behind yours."

Objectively speaking, in terms of mathematics, Princeton is indeed much better than Jida.

If you have such an opportunity, you will definitely not miss it easily.

"In my sophomore year, I won't be able to play with you anymore. But I will be back in a year. See you then!"

Xu You also felt a little sad when he thought about being separated from Lou Song for a year.

"Well, I'll wait for you to come back!"

Xu You was very happy for Lou Song to have the opportunity to study abroad for a year.

Although Xu You has no idea of ​​going abroad, Xu You also knows that compared with domestic universities, some foreign universities do have greater strength.

It would definitely be a good thing to have the opportunity to go out and communicate for a while while ensuring safety.
Chapter completed!
