Chapter 160 I Think I Understand You
Hearing this, Zhao Weijia's face was instantly filled with surprise.
"Is it solved so quickly? Otherwise, let me take a look first?"
This problem has troubled the entire laboratory for several days.
No one even found the cause of the problem.
Not to mention how to solve this problem.
However, Xu You discovered the problem in a relatively short time.
But Zhao Weijia would never have thought that Xu You could solve the problem so quickly.
"Just call Teacher Wang, and the three of us can discuss this together."
Xu You has a better understanding of Zhao Weijia's abilities.
It would be very difficult for Zhao Weijia to understand such a difficult deduction.
Of course, Zhao Weijia does have some abilities, after all, he is a PhD from Ji University.
But it hasn't reached that very high level yet.
"Okay, I'll go get Teacher Wang."
Zhao Weijia didn't think much about it and went to call Wang Xiangwu over.
Wang Xiangwu was also very surprised when he heard that Xu You had solved the problem within half a day.
"Hurry, Xu You, let me see!"
Xu You turned on the computer and first showed Wang Xiangwu and Zhao Weijia the image he had refitted.
"According to my latest approximation method, the error is much smaller than before, and the fit performance is also very good."
Seeing the images on the computer, Wang Xiangwu and Zhao Weijia couldn't help but open their eyes wide.
"Xu You, what method did you use?"
"The mean field approximation. To be more precise, it is the mean field approximation that I have improved upon."
"Mean field approximation?" Wang Xiangwu was surprised.
Wang Xiangwu knew something about this method, but he had never heard of it. The mean field approximation can be applied to this type of problem .
Zhao Weijia was even more puzzled because he had never used such an approximate method before.
Xu You opened his draft paper and explained to Wang Xiangwu and Zhao Weijia.
During this period, Wang Xiangwu asked from time to time how Xu You handled certain matters.
Listening to Xu You's explanation, Wang Xiangwu nodded repeatedly.
" Finally, if we use this formula to calculate the effective Hamiltonian, the error will be much smaller than before. I have tried it, and at least for the current data, there is no problem."
"I never thought that the mean field approximation could be used in this way. Xu You, you really solved a big problem in analyzing the quantum phase transition of the lattice model! Xu You, thank you so much!"
Seeing Wang Xiangwu's excitement, Xu You smiled and said:
"Teacher, if I can really help you, I will be very honored. I feel that I have learned a lot from this problem."
In fact, Xu You felt a little ashamed that he chose condensed matter physics as his major direction instead of quantum physics.
I can take this opportunity to repay Wang Xiangwu for his kindness in recognizing my talent.
"From discovering the problem to solving it, it took less than a day. Xu You, I really can't find any words to describe you. Fortunately, I decided to bring you into the laboratory ahead of time, otherwise your talent would really be wasted!"
Thinking back to his previous experience of meeting Xu You, Wang Xiangwu also felt that fate was indeed very wonderful.
"Xu You, I'm a little suspicious now. Those rumors are true. If you really want to go to Harvard, the president of Harvard will definitely be very happy."
"Okay, senior brother, stop spreading rumors. People wouldn't invite me so casually, and I'm fine doing research in China."
Although there may be better scientific research conditions abroad.
However, the various privileges that Jida gave to Xu You are indeed difficult for foreign universities to give.
Even without considering other factors, Xu You would prefer to continue staying here to do scientific research.
At this time, Wang Xiangwu also began to think about another problem.
Since Xu You has helped them solve such an important problem.
Wang Xiangwu couldn't just say nothing.
Wang Xiangwu definitely could not give the positions of first author and communications officer to Xu You.
But Wang Xiangwu can still give the author position, project bonus, etc.
"Xu You, don't worry. When this project is successful, you will get all the credit."
Xu You shook his head repeatedly when he heard this.
"No need, Mr. Wang. I just helped you a little. It didn't even take me a day. I can't really say I have done you any credit. I'm just happy to be able to help you."
"Xu You, just because you didn't spend much time doesn't mean you didn't help much. If it were someone else, this might be a problem that couldn't be solved in a few months. I will definitely calculate the credit clearly. Of course, you can rest assured that I have your bank card number and I won't charge your phone bill or bus card or anything like that."
Finally, Wang Xiangwu did not forget to make a joke with Xu You, teasing him about the fact that the doctors from Jihang had charged Xu You 10,000 yuan for his phone bill.
Xu You knew that he couldn't refuse, so he had to acquiesce.
After returning to the condensed matter physics laboratory, Xu You was in a very happy mood.
After helping Wang Xiangwu solve this problem, Xu You finally no longer felt like he owed Wang Xiangwu anything.
Looking at Wang Xiangwu's attitude towards him, Xu You also knew that Wang Xiangwu would not care about this matter at all.
When Qiao Sen saw Xu You coming back, he couldn't help but ask:
"Xu You, have you been to the quantum physics laboratory? If there is no progress in the research on the mechanism of high-temperature superconductors, you should go to the quantum physics laboratory for a while."
Qiao Sen naturally would not have thought that Xu You helped Wang Xiangwu solve an important problem in less than a day.
"Teacher, I've been there and the problem has been solved." Xu You said lightly.
"It has been...solved?"
Hearing Xu You's words, Qiao Sen couldn't help but open his eyes wide in surprise, looking incredulous.
"Well, it's a problem of approximate data processing. I went to the library this morning to borrow some books, found a good method, and improved it, and successfully solved the whole problem."
Xu You said it lightly, as if the matter was really that simple.
But Qiao Sen had known Xu You for a long time, and he knew that Xu You had a habit of making a mountain out of a molehill.
"If I'm not mistaken, you dragged your suitcase to the library and borrowed dozens of books, right? You also wrote at least a few draft papers for formula derivation, right?"
Listening to Qiao Sen's words, Xu You thought that Qiao Sen had been following him.
"Haha, teacher, how did you know that?" Xu You said, scratching his head.
"I know you well enough. You never show off your own achievements. If it weren't for Academician Han's advice last time, you would have given up the chance to publish in Nature."
