I really don't want to lie down and win

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

"Correct!"

"But some people 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 teacher before."

"..."

"..."

"..."

don't guess,

It must be Xu Mang!

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

but...

This time I'm afraid it will be difficult!

Fragile topology is one of the globally recognized problems. Although the research team at Oxford University discovered a suspected fragile topology in Xu Mang's magical angular bilayer graphene, many evidences show that it is not fragile topology at all.

Fragile topology is a concept that has harmed many scientists since its birth. Gradually, this field became unpopular until it was discovered not long ago.

Those who really study fragile topology are probably only those 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, then sighed: "Actually... the problem of fragile topology, I went back and thought about it for three days, but I still couldn't find it. There is no way to prove its existence."

"usually..."

"When everyone accepts the strong topology, the phenomenon that can be directly measured, and then look at the weak topology, if the evidence does not reach the level of the former, it will not be convincing." Yanfeng Hua said.

"Ok!"

"I basically agree with this point of view." Professor Li Aimin nodded and said, "We can see from the strong topological search last year that it was judged by symmetry, mirror symmetry, rotational symmetry, and translational symmetry."

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

"What should Xu Mang do?"

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

"I'll tell you what I think."

"Aside from the complexity of the problem, with Xu Mang's name alone, it is natural to discover some brand-new concepts. This... he has completed so many impossible researches before, so 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?

a month?

three months?

Or... half a year or so?

The three professors from the Department of Physics of Fuda University didn't give a specific time. After all, facing the monster Xu Mang, if they reported a time at random, they might be slapped in the face. Xu Mang slapped him not once or twice.

"So cautious?"

"It's nothing... just tell me the time you imagined." 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?

A...day's time?

Are you sure you didn't make a mistake?

"Xiao Fan!"

"You... did you get the time wrong?" Professor Li Aimin said in disbelief: "One day...does it count from today? Doesn't it mean that the result will be known in the afternoon?"

"Correct!"

"According to the time Xu Mang said, the evidence of the fragile topology will be known before 04:30 in the afternoon." Fan Zhilong said, "Although I don't know whether it is true or not, but according to his expression at the time, he looked a little joking."

joke?

This...

This is probably true.

If Xu Mang's expression was serious, it would be doubtful, but Xu Mang's playful smile should be noticed and 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 think of how to find evidence of fragile topology in one day. Could it be that he discovered it before?"

"Correct!"

Fan Zhilong nodded hastily and said, "Old Li, what you said is not wrong. I heard from Xu Mang that it seems to be related to graphene. He discovered this problem when he was researching graphene superconductivity before, but he just didn't pay attention. It was stolen."

Graphene again?

This thing is amazing enough!

"I think if Xu Mang finds a new theory based on graphene, such as this fragile topology, he will basically win the Nobel Prize." Wang Jiafu said seriously: "I'm not joking, the potential of graphene has been overwhelmed by him." Keep digging and there's no end in sight."

Hua Yanfeng smiled and said: "How can it be true, Lao Wang, you are terrible... the teacher of the Nobel Prize winner, it's very embarrassing to spread this reputation!"
