Chapter 445: Expert vs. Authority (2/3)

Everyone looked at this uninvited guest, with the smell of salted fish all over his body, and a smirk on his face. If this is a student, there is a high probability that he will be expelled. However, this is a professor, and Still the deputy director of the physics department!
It doesn't make sense at all...
"Hey!"
"Everyone is there?" Xu Mang said with a smile, "Professor Li... are you free now?"
"What's wrong?" Professor Li asked curiously.
"After a day and night of hard work, I finally designed the laser crystal I need, so what... Help me take a look?" Xu Mang smiled and found a chair, sat beside Professor Li, and took out himself Laptop.
"???"
"???"
"???"
What do you mean?
He actually designed it?
impossible?
Not only is Professor Li looking dumbfounded, all members of this scientific research team are full of doubts. One who is engaged in theoretical physics spent a day and night designing laser crystals. This... how is this possible !
"you..."
"Are you not joking?" Professor Li asked in horror.
"Looking at my beauty in this flourishing age, I know that I like to tell the truth." Xu Mang pointed to his face and said seriously: "I have never lied to anyone. I always take my sincerity. In exchange for the sincerity of others."
Words fall,
Xu Mang clicked on the file in the notebook, and immediately let the teachers and students of optics feel the speechless picture appeared in front of him. At first glance, this looks really good, but I don't know whether the accuracy is high or not.
Professor Li was carefully watching Xu Mang's design, and Kong Fei and other optics majors were also curious to get together.
Uh?
Is a crystal composed of thousands of precisely arranged atoms?
This seems to be similar to the optical crystals of nanomaterials...but there are some differences.
"This..."
"Xu Mang?" Professor Li said to Xu Mang in surprise at the end when he saw it, "Is this really the laser crystal that you spent a day and night out?"
"Yes!"
"Is there a problem?" Xu Mang asked hurriedly: "If there is a problem, I will make corrections quickly."
"No no no!"
"There is no problem!" Professor Li said seriously: "How to tell you... Although this crystal has no effect on our optics professional, it is of great help to you, and even the position of the atom can be obtained. The possibility is far lower than the wavelength used to illuminate atoms."
"This thing of you is 50 times higher than the limit that our optical microscope can usually distinguish!" Professor Li said solemnly: "But... it can only be used for your experiment, and the others are useless."
Xu Mang nodded. The crystal he designed was indeed structured according to experimental thinking, that is, this crystal was a supporting crystal. After the experiment was successful, this crystal was useless.
"Can you process it for me?" Xu Mang asked.
"Absolutely!" Professor Li smiled: "But it will take a few days."
"Oh..."
at this time,
Kong Fei and a few people are a little depressed. They said that Professor Xu didn't understand laser equipment, so he designed the crystal in an instant. Is this world crazy? Basically, it makes sense... a person who is engaged in theoretical physics actually came up with a laser crystal.
"Senior Sister..." a material department student asked curiously: "Didn't you say...Professor Xu couldn't make it out? Why did it make it out in an instant?"
"I..."
"This...then what." Kong Fei said awkwardly: "Professor Xu cannot be defined by simple human thinking. He... you should have read the school forum posts. He is not a normal human being, he is non-human. !"
"..."
"..."
"..."
Although I know that Kong Fei is joking, there is no better explanation except this explanation. After all, there are countless legends of Professor Xu in Fuda, and every legend that belongs to him is full of absurdity.
"Senior sister?"
"Since Professor Xu is free during this period... then we... can we ask him to help us solve the problem?" a Kong Fei's junior said cautiously.
Kong Fei realized this. Now Xu Mang has completed his crystal design. However, there is a three-day window period in between. These three days can be used to guide the research team's problems.
By virtue of his relationship with Xu Mang, shouldn't he refuse?
"Professor Xu!"
"It happens that you are free now." Kong Fei said with a smile: "Help us solve this problem!"
After hearing Kong Fei's words,
Professor Li hurriedly said: "Xu Mang just happens to have time for you to guide the problem of Kong Fei's group."
"what?"
"Professor Li, you can't solve it?" Xu Mang asked curiously.
Professor Li shook his head and said seriously: "It looks like this is an optical problem, but in fact it is a problem of your theoretical physics and condensed matter physics. The transformation from two-dimensional to three-dimensional requires the support of a physical theory, plus The topological insulator itself is a condensed state."
"Oh?"
"Such high-end?" Professor Li's explanation made Xu Mang curious. He turned to look at Kong Fei and asked, "What problems have you encountered?"
moment,
Xu Mang has an extra research project plan in his hand. After reading it briefly, Xu Mang can’t help but praise several people. This is indeed a very good research direction. If successful, it will have a huge impact on the future of photonic chips. effect.
In many devices, the electromagnetic wave must go around the bend, and once the turning amplitude is large, the electromagnetic wave will be scattered, which affects the transmission efficiency. The small turning amplitude is not conducive to saving space. Kong Fei’s intention should be when making a sharp turn. There will be no scattering.
at the same time,
Kong Fei and the others are very nervous. After all, Xu Mang is the last hope. If even Xu Mang can't solve it, this issue can only be ended.
No one dared to speak,
For fear of affecting Xu Mang's thinking.
"This..." Xu Mang said, but stopped abruptly.
And this sudden opening almost frightened Kong Fei and all of them fainted.
how?
Is there a problem?
Wrong idea?
"This one..."
"Yes!" Xu Mang said with a smile: "Not bad, not bad...The creativity is very good, and once successful, it is estimated that it will have a huge enlightening effect on the future photonic chip."
Damn it!
Professor Xu is too bad!
A big gasp on purpose.
"Professor Xu!"
"Can you finish it all at once the next time you speak?" a student said helplessly: "You almost scared us to death. At first I thought our research project was finished, and it didn't work."
"Hey..."
"Tease you." Xu Mang said with a smile: "Your research project has some high-end...Many of them belong to brand-new theoretical systems, such as the transformation from two-dimensional to three-dimensional. First, the design of three-dimensional optical topological insulators must be proposed. Theory, but you don’t!"
"There is no experimental system... I don't know what your first study is to study topological insulators or to study the scattering problem..." Xu Mang said solemnly: "And... you didn't catch the point, three-dimensional The key features of optical topological insulators...you haven't summarized them."
"..."
"..."
"..."
Kong Fei wanted to say something, but in the end he held it back. This matter needs to be resolved in private.
"Then what..."
"What problems do you want me to solve?" Xu Mang asked curiously: "It seems that there are many problems..."
For a while,
Kong Fei didn't know what to do. According to Xu Mang's words, there were indeed too many problems, and almost every one of them needed to be solved.
"Professor Xu..."
"Why don't we find a suitable material for us." A student said sincerely: "All our problems are in this place."
Xu Mang read their plan repeatedly, indeed...According to this experimental plan, the problem lies in the materials, but there is a lack of a perfect system. Even if you get the right materials, you will encounter a lot of other things in the future. problem.
Xu Mang shook his head and said seriously: "Your experimental system is not good. Even if you know the materials, you will encounter a lot of trouble."
For a while,
Kong Fei's team was in an embarrassing situation at a loss, but Kong Fei had some difficulties.
"but..."
"It happens to be a period of time when I am free, so I can help you guide." Xu Mang said with a smile.
Hearing Xu Mang's words,
Several people regained hope. As long as Professor Xu is there to guide, many problems are not a problem at all.
after that,
Professor Li left with Xu Mang’s plan. He wanted to help Xu Mang complete this special laser crystal, while Xu Mang himself stayed in the optical laboratory, watching the members of Kong Fei’s team, making changes to the plan, and trying his best The system for completing this experiment.
With Xu Mang's assistance, the team quickly completed the relevant progress, but the problem was not resolved, and several people still faced endless problems.
quickly,
Interval rest time. .
Kong Fei found Xu Mang alone, and met an old friend in private, and Kong Fei unceremoniously called Xu Mang by his full name.
"Xu Mang!"
"Tell me honestly." Kong Fei asked solemnly: "Is it very difficult for us?"
"..."
"It's okay." Xu Mang said: "Speaking of high is not high, and low is not low. The main reason is that there is a problem with the structure of your team. There is no student of theoretical physics or condensed matter physics."
Kong Fei hurriedly defended: "In fact, we are cooperating with Nanyang Technological University. The reason why some aspects are not studied is because those fields belong to them, such as this theoretical framework and what you said about the characteristics of topological insulators."
Xu Mang froze for a moment, Nanyang Technological University?
Before Xu Mang could speak, Kong Fei sighed and said: "The research team we are working with protects its data very well, for fear that we will plagiarize them, but for our data, I kept urging me to submit it. ."
"just now..."
"The cooperation exists only in name, and in fact there is no exchange." Kong Fei said: "In general...we were pitted by them, causing problems in our personnel structure, and their research progressed very fast."
Xu Mang frowned, and said with an unhappy expression: "Who is the other party's mentor? What is the background?"
"seem..."
"Is a very famous condensed matter physics expert. I don't know what UU read www.uukahnshu.com is called." Kong Fei said: "I didn't dare to tell anyone about this situation. Passion for research."
Xu Mang nodded, but he was very upset. A well-known condensed matter physics expert?
Okay,
Experts meet authority and see who is better!
"Humph!"
"A bunch of clowns jumping on the beams." Xu Mang showed disdain: "We will solve this in two days, so that so many people will die!"
