Xu Mang suddenly felt a little helpless. Perhaps the worry was unnecessary. Although the Quantum Research Institute under Fermilab successfully proved the Klein tunneling phenomenon using graphene, the evidence was still not sufficient. If this kind of evidence is used to explain Regardless of whether others can accept Klein Tunneling, you will never be able to pass it.

According to a report from the Quantum Institute under Fermilab, they studied the tunneling properties of a strained graphene monolayer driven by a vertically acting magnetic field, giving the transmittance across a magnetic barrier through a transfer matrix.

The study found that in small-angle scattering, unlike Klein tunneling in an electric barrier, a magnetic field can bind electrons in a strained magnetic barrier. As long as the incident energy is not very large, the presence of strain can significantly increase the orientation. transmittance.

When the injected energy is very large, the effect of strain is completely removed, making strained graphene and ideal graphene have almost the same tunneling properties.

In general,

This is the tunneling characteristic of graphene in a magnetic field under stress.

sorry,

I cannot accept such evidence!

Xu Mang was full of disdain for this. It was obvious that this was a sign of eagerness for quick success. He probably knew of his existence and accelerated the research, which led to such a problem. There was a lack of conclusive evidence.

"Professor Xu?"

"Do you have any good ideas?" The young graduate student said cautiously: "Now the physicists in the Western world are happy about this. They think that in the field of physics, you are no longer the one who maintains the position. The undefeated man, now you can be defeated."

Xu Mang was stunned for a moment and asked curiously: "Do you think you can defeat me? Isn't it just the tunneling properties of graphene in a magnetic field under stress? What's the big deal? Regardless of whether others are willing to admit it or not, anyway, I It is to deny that this evidence proves Klein tunneling."

"But" the young graduate student said: "The whole world thinks so, and we haven't even found the right materials yet. It's really difficult to surpass."

"Who said that?"

"I don't agree!" Xu Mang said seriously: "Isn't it just to find a suitable topological insulator material? Joking has never been so difficult in my dictionary, just close your eyes and open it!"

""

Hearing Xu Mang's words, the young graduate student smiled bitterly. No one can brag about this awesomeness, but only Professor Xu Mang can. There is no way he is good at realizing the awesomeness. However, the awesomeness just now was a bit too much. .

"Ahem!"

"Professor Xu Mang, how confident are you?" the graduate student asked cautiously.

"grasp?"

"One hundred and twenty percent." Xu Mang said calmly: "You go back now and tell them by the way, don't have any worries. I'm here for everything. Don't be afraid. Speaking of the research report on the mechanism of super-large black holes, What’s the impact?”

“The impact has been extraordinary.”

"We have passed "Nature Astrony"." The graduate student said excitedly: "We don't know why it happened so quickly. Maybe it's because of you, but a few of us have been on the school's homepage."

"oh"

"Keep working hard!" Xu Mang said casually, then turned on the computer and continued: "Hold the door for me when you go out."

moment,

Xu Mang is the only one left in the office. He is not relaxed now. People who oppose him all over the world are having a party, and suitable topological insulator materials are far away. What should we do?

Xu Mang fell into silence. According to the previous two days of research, basically this topological insulator material is a hybrid material, that is, the interior is an insulator, but the surface is metallic, and under certain conditions, the surface can transform into a

superconducting materials.

This greatly increased the difficulty. Initially, the material samarium hexaboride was chosen, because samarium hexaboride meets the conditions of being an insulator inside but a metal on the surface, and the surface allows electrons to move freely, while the direction of electron movement is locked.

on an intrinsic quantum property called spin.

However, its surface does not have the conditions to realize a Klein tunnel. Either a new topological insulator material is selected, or the samarium hexaboride material is specially processed. Each choice is very difficult, and it is almost a desperate situation with no way back.

but

Xu Mang prefers the second option, which is to perform special processing on the samarium hexaboride material.

"How the hell can samarium hexaboride be turned into a superconducting material?" Xu Mang couldn't think of a way to do it. It is simply not something that humans can solve. Turning a topological insulator material into a superconducting material is no less difficult than

The short and flat girl turned into a tall and curvy girl.

"Oh my God!"

"It's so difficult!" Xu Mang sighed. If he wants to succeed in this area, he must be proficient in topological physics, condensed matter physics, spectroscopy, and theory at the same time. But he has clearly reached the top in all of them, so why can't he still do it?

Solve the problem.

"Hello?"

"Director Fang?"

"Do you have anything to do with me?" Xu Mang received a call from Fang Jun, the director of the Physics Department of Fuda, and said feebly: "I am quite desperate now. To use an Internet term, "Baby" is in my heart, but "Baby" doesn't say anything. I'm so miserable.

"

""

"Is it about the Quantum Research Institute under Fermilab successfully proving Klein tunneling using graphene?" Fang Jun said calmly: "It is normal to fail occasionally. After all, people cannot go on smoothly all the time."

That's true, but I feel very dissatisfied.

"Speaking of Director Fang?"

"Are you looking for me just to enlighten me?" Xu Mang asked curiously: "I am now a world-renowned great scientist, and I will be your equal in the second half of the year. By then we will both be academicians of the Academy of Sciences.

"

"You boy"

"Forget it, forget it." Fang Jun said with a wry smile: "The principal asked me to ask you, do you still need graduate students to do research at your place?"

ha?

Do you really think this is a training institution?

Come whenever you want?

"Ahem!"

"It's not necessary for the time being." Xu Mang said with a smile: "By the way, I will charge double the fee in the future. They will eat my own food, drink my own food, and use my own food. I will also pay them a salary, Director Fang. From now on, each person will be charged per person per year.

A graduate student who comes to me as an intern charges a fee of RMB 500,000, and the school has to bear half of the research topic."

""

"You should talk to the principal about this matter in person. If he agrees, I have no objection." Fang Jun said with a smile: "Then hang up first."

Snap!

Hang up the phone directly.

Xu Mang hurriedly called his second grandfather and asked about raising money and sharing scientific research funds. Not to mention that he didn't know how to speak for a while. When there was a 'beep', he hung up directly. Xu Mang needed

Organize the language.

Two minutes later,

Xu Mang dialed the phone again, and soon the urgent call came through.

"Hello?"

"Hey, hey, second grandpa?" Xu Mang asked with a smile, "How are your health recently? Can you handle it?"

""

"I was still in good health at first, but your boy called me and I now have a little cerebral congestion." The second grandfather said angrily: "Did you come up with some bad idea again?"

"Ahem!"

"Second Grandpa, am I this kind of person?" Xu Mang said cautiously: "Then I am here to discuss with you. Regarding the graduate students who come to my institute for internship, I think I will have to pay them in the future.

It’s money, but this time I’m just testing the waters.”

Regarding the matter of giving money, the second grandfather knew about it before. He was quite puzzled before because Xu Mang didn't call to pay, but now the call finally came.

"Um!"

"I know about this." Second Grandpa nodded.

"What then"

"Second Grandpa, I think you've made a mistake." Xu Mang said seriously: "I'm saying that we need to add more money in the future. Don't be angry. Don't be angry. Listen to my explanation. Second Grandpa, you understand the situation in my family. Xiaoman is a prodigal mother.

We are so prodigal. If I don’t make some money to support our family, I’m afraid our young couple will starve to death in the future.”

Hearing Xu Mang's words, the second grandfather almost went crazy. This guy really opened his mouth and couldn't help laughing and scolding: "You boy, I am your second grandfather, and I don't know the situation at home? Brat, your wife made money last year."

How much, your father-in-law has already told me."

Oops

This is crazy,

Xu Mang was a little embarrassed and said with a smile: "What about adding money?"

"Don't think about it!"

Snap!

Hang up immediately.

Xu Mang was stunned for a moment, thinking that he was hearing hallucinations. After confirming again and again, he was sure that he was hung up on by his second grandfather.
