this day,

Fan Zhilong found several industry leaders, including Wang Jiafu, a leader in theoretical physics, Hua Yanfeng, a professor in the field of particle physics, and Professor Li Aimin, a professor in optics. Taking a free opportunity, Fan Zhilong told the three of them a situation.

"Tell you something..."

"Don't be surprised!"

"Remember the fragile topological state problem we discussed before?" Fan Zhilong said with a mysterious face.

Wang Jiafu nodded and asked curiously: "Aren't we still making judgments on this issue? It is almost impossible to find direct evidence. After all, this is not a strong topology. If we still calculate the topological properties based on the chemical properties and symmetry of the material,

Basically impossible."

"right!"

"But there are people who don't believe in evil." Fan Zhilong said seriously: "He... I won't elaborate too much. You all know him very well. Professor Wang, you were his class tutor before."

"..."

"..."

"..."

No need to guess,

It must be Xu Mang!

The three of them almost pointed the finger at the same person. In the minds of Wang Jiafu and others, only Xu Mang had the ability not to believe in evil. When the whole world was questioning it, he dared to go up and slap everyone in the face.

but...

I'm afraid it will be difficult this time!

Fragile topology is one of the globally recognized problems. Although the research team at the University of Oxford discovered a phenomenon suspected of fragile topology in Xu Mang's 'magic angle' double-layer graphene, a lot of evidence shows that it is not a fragile topology at all.

Fragile topology is a concept that has troubled many scientists since its inception. Gradually, this field became unpopular. Until the recent discovery, the thunder was loud but the rain was small, and many people took a wait-and-see approach.

The only ones who really study fragile topology are the top research schools in the world.

"Xu Mang..."

"I'm very curious about how he plans to solve this problem that is a headache for the whole world this time." Hua Yanfeng thought for a long time and sighed: "Actually... I went back and thought about the problem of fragile topology for three days, but I still can't find it.

There is no way to prove its existence."

"generally..."

"After everyone accepts strong topology, a phenomenon that can be directly measured, and then look at fragile topology, if the evidence does not reach the same level as the former, it will be unconvincing," Hua Yanfeng said.

"Um!"

"I basically agree with this point of view." Professor Li Aimin nodded: "We can see from last year's strong topology search that symmetry was used as the judgment at that time, mirror symmetry, rotational symmetry and translational symmetry."

"The symmetry direction determines where and how electrons move in the lattice of the crystal structure..." Professor Li Aimin continued: "Symmetry can also be used to predict electron behavior, and then predict whether the material may have a topological state."

"What should Xu Mang do?"

Li Aimin asked: "How should he judge fragile topology? Or how to determine fragile topology? At present, the research institution at Oxford University has only discovered suspected fragile topology phenomena. Whether it is still under debate."

"I'll tell you what I think."

"Disregarding the complexity of the problem, just by using the name Xu Mang, it is natural that some brand-new concepts will be discovered. This point... He has completed so many impossible studies before, I don't need to say more." Fan Zhilong said.

: "Just give him time..."

"pity..."

"Do you know how much time Xu Mang plans to spend this time?" Fan Zhilong asked seriously.

How much time?

One month?

Three months?

Or...about half a year?

The three professors from the Physics Department of Fuzhou University did not give a specific time. After all, facing the monster Xu Mang, if they randomly reported a time, they might get slapped in the face, and they were slapped in the face by Xu Mang more than once or twice.

"So cautious?"

"It's okay... just tell me the time you envision." Fan Zhilong said.

"I think half a month."

"I guess a week."

"Ten days?"

Faced with this completely different answer, Fan Zhilong smiled and said seriously: "One day!"

"???"

"???"

"???"

What?

One... one day?

Are you sure you're not mistaken?

"Xiao Fan!"

"Did you...did you get the time wrong?" Professor Li Aimin said in disbelief: "Does the day start counting from today? Can't we know the results in the afternoon?"

"right!"

"According to the time Xu Mang said, the evidence of fragile topology will be known before 4:30 in the afternoon." Fan Zhilong said: "Although I don't know whether it is true or not, but based on his expression at the time, he looked a bit joking."

joke?

this...

This is probably true.

If Xu Mang had a serious expression, it would be suspicious. However, if Xu Mang showed a playful smile, this would actually require attention and be taken seriously.

"one day..."

"How... is this... possible?" Professor Li Aimin thought for a long time, shook his head and said, "I really can't figure out how to find evidence of fragile topology in one day. Has he discovered it before?"

"right!"

Fan Zhilong nodded hurriedly and said: "Mr. Li, you are right. I heard Xu Mang said that it seems to be related to graphene. He discovered this problem before when he was studying graphene superconductivity, but he just didn't pay attention. It was discovered by Oxford University.

Stolen."

Graphene again?

This thing is so magical!

"I think if Xu Mang finds a new theory from graphene, such as this fragile topology, he will basically win the Nobel Prize." Wang Jiafu said seriously: "I'm not kidding, the potential of graphene has been blown away by him.

Keep digging, there is no end in sight.”

Hua Yanfeng smiled and said: "How true it is, Lao Wang, you are incredible... a teacher who is a Nobel Prize winner, if you tell this reputation, it is very honorable!"

"hehe..."

"Forget it, forget it, I don't want this kind of reputation, but...my daughter Wang Ai works in Xu Mang's laboratory, as long as she gets the glory." Wang Jiafu is a father after all, and he will give priority to his children in everything, especially

is the future.

at the same time,

Condensed Matter Laboratory,

Xu Mang was conducting the final experiment. He almost came up with a solution from the Oxford University research team's paper. In fact, he still relied on graphene for superposition, but this time he changed his strategy. He sandwiched graphene between two layers.

between two two-dimensional materials tungsten diselenide, and then an electric field is released.

"call..."

"The last step!"

Xu Mang looked at the complex equipment in front of him. He had asked Xiaoman to complete it before, but now... he had to rely on himself.

"System...I want to quickly master how to use this experimental equipment."

[Identified by the system, the current experimental equipment proficiency exchange value is: 1000 (physical skills)]

Xu Mang: Embarrassed

sorry,

Excuse me!

What Xu Mang lacks most now is skill value. Good guy... Just to master the control of the equipment, you have to pay 1,000 points of physical skills. What the hell is this not robbery?

Aren't you tired from sleeping?

Beat him to death without paying!
