Chapter 444: Kong Fei's embarrassing situation (one/three)

The next day,
As usual, Professor Li Aimin brought his own textbooks to class with the students. Xu Mang’s appearance yesterday did not disrupt his regularity, but he just lamented that Xu Mang was a bit stubborn. He knew that it was difficult, but he still had trouble. Iron is going to do it.
To be nice is called stubbornness, and to be ugly is a bit silly, no...it's silly!
The class is over soon,
Just as Professor Li Aimin was leaving, one of his protégés, Kong Fei, approached him. There was a problem that required Professor Li's help.
As a leader in optics, Kong Fei’s research group cooperated with a research group of Nanyang Technological University to find a three-dimensional optical topological insulator. The goal of these two research groups is to extend the three-dimensional topological insulator from the fermion system to Boson system.
This greatly improves the transmission efficiency of photons in the waveguide.
but,
Both sides have encountered problems. The research on three-dimensional optical topological insulators is still blank in this field. Experimental research on optical topological insulators is limited to two-dimensional space. In many cases, a group of people is in the cloud.
"Professor Li."
"Now we have encountered a very troublesome and troublesome problem." Kong Fei said earnestly: "We have encountered difficulties in the design of three-dimensional optical topological insulators, and lack a new type of artificial anisotropic dielectric material."
"material..."
"You'd better find the materials department." Li Aimin said: "Maybe I can help you."
"..."
"Professor Li... Two of our research groups are from the Department of Materials Science." Kong Fei said bitterly: "The two went to find their mentor, but they did not satisfy us. The material issue, this experimental design is also a big issue."
Kong Fei is desperate. She chose this subject herself. Nanyang Technological University also found an invitation to study together. As a result... Just the first two weeks, she encountered threefold troubles in theory, materials, and experiments. Come, it seems to be a false proposition.
"I'll take a look for you in the afternoon." Professor Li said, "but you also have too much hope. I probably don't know."
"As long as you can come."
come back to the office,
Professor Li has done various researches on this topological insulator. In fact, topological insulators are a research hotspot in the field of condensed matter physics. This is a very interesting material. The inside is insulated, but the surface can be energized.
Inside a topological insulator, the electron band energy result is very similar to that of a conventional insulator. The Fermi level is between the conduction band and the valence band, and the quantum state on the surface lies in the band gap of the bulk band structure, allowing conduction.
but...
Trying to extend the theory of topological insulators to optical systems, although it has been verified in two dimensions, a research team at Princeton University has realized two-dimensional optical topological insulators through experiments. However, this three-dimensional optical topological insulator... Not optimistic.
in the afternoon,
Professor Li Aimin came to Kong Fei’s laboratory and saw her experiment. The result was a little helpless for Professor Li. This subject is currently in a theoretical state. There is no ready-made experimental equipment to help with the measurement, and even the theory has problems. .
This is not to blame Kong Fei, after all, this is a brand-new field, starting from scratch... It’s not easy to talk about building a scientific fortress in the ruins, from the electronic system to the optical system, from two-dimensional to three-dimensional, the research object There are many essential differences.
"It's over..." a student said pessimistically, "Professor Li... do we still have a chance to be rescued?"
Hearing this student's words, Professor Li smiled bitterly. Under normal circumstances, the death sentence was pronounced, but...not to the point where it cannot be studied. There may be opportunities in the future.
"in fact..."
"You still have a chance." Professor Li said solemnly: "As long as the materials can be found, the remaining problems will almost be solved."
material,
Why not!
But just can't find it, even the material department is helpless.
"Yes!"
suddenly,
Kong Fei shouted with excitement. Just now, the shadow of a appeared in her mind. There was a smirk on this person's face. It looked like a vain appearance, but it often gave people unexpected surprises. .
His nickname is Pipixu, whose real name is Xu Mang...Professor of theoretical physics in the Department of Physics. He was his junior brother six months ago.
"Professor Xu!"
"We can ask Professor Xu for help, he may be able to solve our problems." Kong Fei shouted.
Xu Mang?
Professor Xu?
Yeah!
Hearing Kong Fei's words, everyone present except Professor Li was extremely excited, but... Professor Li Aimin was a little helpless.
"If you want to find Professor Xu, it is estimated that it will take a while." Li Aimin said seriously: "He is designing a brand new laser equipment."
"???"
"???"
"???"
what?
Professor Xu, who is engaged in theoretical physics, actually started to involve laser equipment?
The faces of several optical professionals are all confused. It is not that a few people look down on Professor Xu Mang, but... This is not in line with science. It is like a singing and dancing person who suddenly goes to the NBA to play basketball. How could it be possible... .
Let alone the NBA, it is estimated that even the school team will not get in.
"Professor Li?"
"You... are you kidding?" Kong Fei asked in surprise: "Professor Xu is really designing laser equipment? He... isn't he studying theoretical physics? Why is he studying optical equipment all of a sudden? Professor Xu can't think about it again?"
"This..."
"He is using laser equipment to study the probability of quantum mechanics, to detect the probability of the appearance of atoms in space." Li Aimin said: "Anyway, you temporarily give up the decision to find Xu Mang. Now he is really out of time."
After Li Aimin left,
The laboratory was very lively. They were not discussing the problems they encountered, but the topic of Xu Mang's design of laser equipment.
"Senior sister?"

You seem to have worked with Professor Xu. Do you think that Professor Xu designed a brand-new laser device with a high success rate?
A student asked curiously,
I am studying materials, and I don’t know your physics department. Door frame."
"difficult!"
"Almost impossible." Kong Fei said seriously: "Although Professor Xu once used pure mathematics and found that light can propagate in a spiral manner, thus proving a self-torque property of light, this is theoretically proved. "
"Almost all of his results are based on theoretical calculations." Kong Fei paused, and continued: "It is totally impossible to design laser equipment based on theory. Please trust someone from optics."
This...
Didn't Professor Xu give it for nothing?
"Senior sister?"
"Then why is Professor Xu..." The student frowned and asked with a confused look: "Then what else did he design?"
Kong Fei thought for a moment. Faced with this Pipishu, she really couldn't find a reason to explain this weird behavior. No reason was applicable to Pipishu.
wrong!
It may be idle!
"It's more free." Kong Fei smiled helplessly: "Anyway, that's it... don't discuss him, now we study our own."
Words fall,
Everyone in the laboratory is once again caught in their own dilemma.
...
4:30 in the afternoon,
Tired, Yang Xiaoman returned to the place where he belonged to Xu Mang and opened the door to see his dear. He threw himself in front of the computer and didn't know what to do, but when he came to this temporary residence with little space At this moment, Yang Xiaoman's fatigue was wiped out.
perhaps...
This is the feeling of home.
"Idiot?"
"What are you doing?" Yang Xiaoman sat next to Xu Mang, leaning his head on his shoulder, looking at the three-dimensional map on the computer, and asked with a confused face: "Are you building a model? How normal? The model is different?"
"Design a laser mesh lattice, a crystal composed of thousands of precisely arranged atoms." Xu Mang said seriously: "I intend to verify a quantum mechanics question of probability, whether probability equals everything in a quantum system. "
Uh?
This...Isn't this what I'm doing, my old lady?
Yang Xiaoman froze for a moment. She and her small team are playing this probability game. Generally speaking, the market is often in a state of uncertainty and it is difficult to accurately measure and estimate.
Therefore, Xiaoman will conduct various profitable transactions, and then various risks, but... the speed of making money is too slow. Now Yang Xiaoman intends to give up hedging and directly adopt high-risk and high-yield investments. mode.
In short,
Her appetite is not five hundred million one year later, but one billion one year later.
"Uh..."
"Do you still design lasers?" Yang Xiaoman asked with a confused look: "Are you planning to harm the optics major?"
"..."
"What is a scourge?" Xu Mang turned his head and glanced at Xiaoman, and said helplessly: "This is called...Forget it, the scourge is scourge!"
"cut!"
"You seem to be dissatisfied with your tone, it was originally a scourge." Yang Xiaoman gave a white look and said angrily: "Idiot..."
"How much did you earn today?" Xu Mang asked.
"Okay."
"I earned a BMW 740 today." Yang Xiaoman stretched out and said with a grin: "On your birthday... how about I buy you a sports car? Today I heard from several members of the team. Boys are talking about sports cars, it seems...there seems to be a kind of car called Aphrodite."
Xu Mang looked at Xiaoman in horror. This woman must be crazy... Apollo, the sun god, dare to drive this car by herself? I accidentally rubbed it, and the suicidal heart was gone, and this car was not available.
"Forget it...I dare not open it even if I buy it." Xu Mang smiled.
Yang Xiaoman pouted, as if thinking of something, hurriedly said: "Then...then how about I buy you a Panini?"
Xu Mang:? ? ?
what?
Panini?
KFC breakfast?
"Pagani?" Xu Mang's face was full of black lines, and said helplessly: "Twenty to thirty million..."
"how?"
"Your future wife will make money so much, will you put 20 or 30 million in your eyes?" Yang Xiaoman said disdainfully: "I have decided. Every year on your birthday, I will give you a sports car. You want it and you want it. If you don’t want it, anyway...it’s a happy decision!"
"Do you know my birthday?" Xu Mang asked.
"X Month XX Day!"
Taking a look at Xu Mang, Yang Xiaoman asked, "Where is my birthday?"
"..."
"Oh!" Xu Mang stood up suddenly and looked at the direction of the kitchen: "There is no more food in the refrigerator!"
Words fall,
Ran away in a hurry,
Leaving Xiaoman with a confused face.
"Ah!"
"Asshole!"
"I just told you a few days ago, you forgot it again!"
...
early morning,
Xu Mang came to the Physics Department building with his notebook on his back, knocked on the door of Professor Li Aimin's office for a while, but no one responded.
"Classmates?"
"Do you know where Professor Li Aimin is?" Xu Mang caught a student and hurriedly asked.
"in..."
"In the optical laboratory on the fourth floor~EbookFREE.me~Professor Xu." The student said respectfully.
"Oh..."
After bidding farewell to this kind classmate, Xu Mang hurriedly came to the entrance of the optical laboratory on the fourth floor and found that the door was half-hidden. He couldn't help but push in and saw a group of people sitting inside, including Professor Li Aimin.
"what?"
"Xu Mang?"
"How did you come?"
