Chapter 145 I finally published my paper
Xu You had never thought that before learning how to use a device, he would have to learn about the fault conditions first.
But since this is a type of equipment where the failure time is longer than the normal state time, it is very necessary to first understand the various failure problems.
"In fact, the main faults all occur in the vacuum system, which is also a kind of fault that is difficult to avoid for this type of equipment. This kind of fault can usually be found out in one day, repaired in half a day, and then it takes a few days to bake it out to remove the gas and achieve the ideal vacuum environment, and then it can continue to be used."
"Of course, if a screw is broken or there is a water or air leak, it may take longer to troubleshoot."
Listening to Cao Quanli's words, Xu You also understood the key point.
That is, if the ARPES equipment is functioning normally, we must quickly collect a few more sets of data.
This will prevent equipment failure and time from being wasted waiting for baking and degassing.
Through Cao Quanli's introduction, Xu You learned that the ARPES device at Ji University is one of the more advanced devices of its kind.
This ARPES device can use the time of flight of electrons to measure the energy of electrons.
This allows the detector to simultaneously measure the electron information of an entire surface in the two-dimensional momentum space.
Compared with most spectrometers that use one-dimensional momentum detection, the momentum detection efficiency is improved by at least two orders of magnitude.
After learning how to use the equipment, Xu You began his own experiment.
First, Xu You needs to measure various high-temperature superconductors to obtain various data such as their crystal structure, band structure, etc., so as to analyze their superconducting mechanism.
During the experiment, it was not as exaggerated as Cao Quanli said that the equipment was under repair for a long time.
Of course, ARPES equipment is still prone to failure.
Xu You focused a large part of his energy on repairing equipment.
However, Xu You was not bothered by this.
After all, repairing equipment itself is also part of scientific research work.
When the equipment is in the baking state, Xu You can also organize the data with peace of mind, study the crystal structure, 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 period 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 as soon as possible.
"Teacher, even for the same Fermi surface, copper oxide 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 this is still a long way from perfecting the mechanism of high-temperature superconductors.
But at least we have taken a step closer to explaining the mechanism of high-temperature superconductivity.
"Yes, this theory is groundbreaking. How does it feel to work on a 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 but burst into laughter.
"There's nothing I can do about it. This kind of equipment is very delicate. But if you want to do research in this area, the ARPES experiment is essential. Okay, go ahead. If you have any new progress or any problems you encounter, you can contact me directly."
To be honest, Qiao Sen did not expect that Xu You would be able to make some breakthrough progress so quickly.
If this momentum continues, it won't be impossible for Xu You to really figure out the mechanism of high-temperature superconductors.
After these days of hard scientific research, Xu You has somewhat neglected relaxing activities.
The fatigue level of the system interface has accumulated to nearly the upper limit.
It just so happened that Lou Song asked Xu You to play ball with him, and Xu You agreed decisively.
Because he had been neglecting exercise recently, Xu You's ball skills had not improved but deteriorated, and he was beaten even more badly by Lou Song.
However, Xu You does not care about winning or losing. As long as he can relax through exercise, it is the greatest success.
After playing ball, Lou Song took out a book from his schoolbag and handed it to Xu You mysteriously.
Xu You took it and looked at it, and found it was a journal.
"Is this... Mathematics Yearbook?"
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 roughly guessed why Lou Song wanted to give him such a journal.
“Have you published a paper on it?”
"Hehe, you'll know after you take a look."
Seeing Lou Song's mysterious look, Xu You simply started flipping through the journal himself.
Sure enough, on a page of the journal, Xu You saw the paper from Dasong from Jilin University.
"That's amazing! You're only 16 years old, and you've already published papers in four major journals! You're not far right?"
"I'm not as good as you. We're both freshmen, but you've already published so many papers. I'm still a long way from winning the Fields Medal, but I will work hard in this direction."
At this time, Xu You was also truly happy for Lou Song.
Xu You carefully put the journal into his bag and decided to go back and keep it together with the other journals he had published.
"By the way, let me tell you something. I'm going to Princeton's Department of Mathematics for an exchange year in my sophomore year. I've already completed the formalities."
Xu You was not too surprised to hear the news.
"That's great. This is indeed a great opportunity. Have you finished your TOEFL test?"
"Yeah! I've been preparing for this, so I finished the exam a long time ago."
"That's amazing. I just took the Level 4 test, and my English is way behind yours."
Objectively speaking, Princeton is indeed much stronger than Thistle in mathematics.
Such an opportunity will definitely not be missed easily.
"I won't be able to play basketball with you during my sophomore year. But I'll be back in a year, see you then!"
Thinking about being separated from Lou Song for a year, Xu You felt a little sad.
"Well, I'll wait for you to come back!"
Xu You is very happy that Lou Song has the opportunity to go abroad for exchange for a year.
Although Xu You had no intention of studying abroad, he also knew that some foreign universities did have stronger strengths than domestic ones.
It would definitely be a good thing to have the opportunity to go out and communicate for a while while ensuring safety.
