I really don't want to lie down and win

colleague?

Yang Xiaoman recalled what he said just now, and at the same time, he and his mother-in-law...

at the same time?

colleague?

Xiaoman pinched Xu Mang's face, and said helplessly, "Okay...I know I was wrong, can you stop showing your ugly face, and quickly...smile!"

In a blink of an eye,

Xu Mang went from passive to active.

had dinner,

Xu Mang sat in front of his computer and began to think about how to solve the current problem. He was ashamed to say it today. He was going to look for inspiration, but he fell asleep all day after finding it. Fortunately, the environment at that time gave him a lot of skills. It's worth it, otherwise it's a miserable day.

Speaking of...

What is the source of my own inspiration?

like...

Xu Mang gradually recalled the previous episodes, and he felt that he was getting closer to the truth.

Fermions!

right...

That's it!

Xu Mang finally remembered what the previous shining point was. A kind of particle called a fermion. In a system composed of identical particles, if only one particle is allowed to be accommodated in a quantum state of the system, this species called fermions.

of course,

What Xu Mang was looking for was another artifact.

Weyl fermions!

A massless fermion.

Xu Mang felt... There is an inevitable connection between Weyl fermions and axions.

But at this time he was facing a greater challenge. Finding Weyl fermions is no easier than finding axions. Weyl fermions were born in [-]. According to the mass of zero, the Dirac equation describes a pair of overlapping new particles with opposite chirality.

This kind of particle is called Weyl fermion, unfortunately...80 years have passed, and human beings have not been able to observe Weyl fermion in experiments.

It looks like this,

Weyl fermions are more difficult than axions, but in fact they are not.

This particle can be solved according to the Dirac equation, which has a very complete formula.

pity...

The detection of Weyl fermions requires the discovery of Weyl semimetals.

"Fuck!"

"Is it over? I'm just like finding the axe. How come there are so many things all of a sudden?" Xu Mang's head was about to explode. A 42-year-predicted axe was derived from an axe more than 80 years ago. Weyl fermions, and a Weyl semimetal.

At this time,

Yang Xiaoman was sitting on the sofa, eating snacks and watching TV programs when he suddenly heard Xu Mang's complaint, turned around and saw the idiot holding his head with a painful expression on his face. Speechless.

OMG!

Could this guy drive himself crazy?

"Ugh?"

"Don't grab your hair...hair is innocent." Yang Xiaoman put down the potato chips, walked behind Xu Mang, rubbed his cheek, and said softly, "Don't worry...take your time in everything, It will be resolved one day."

"Oh..." Xu Mang thought about the solution.

Weyl semimetal materials...

When two spin-nondegenerate energy bands are required to cross linearly near the Fermi level, the low-energy quasiparticle excited state is consistent with the behavior of Weyl fermions, but... this also brings a whole new problem. If the outer If the Weyl fermion state exists, many new physical phenomena will appear in Weyl semimetals.

Um...

Then start from this aspect first, and construct the physical phenomena of Weyl semimetals step by step.

Thinking of this,

Xu Mang slapped Xiaoman's troublesome hand away, took out his cell phone and called Fan Zhilong.

"Hey?"

"Professor Fan!"

"I need your help. See you at the condensed matter physics lab at nine o'clock tomorrow morning."

Without giving Fan Zhilong any chance to speak, Xu Mang hung up the phone directly, and then began to think about the physical properties of Weyl semimetals, and made reasonable speculations based on the theoretical prediction of Weyl fermion states.

Right now,

Yang Xiaoman was a little embarrassed. She felt that she was superfluous in this family. Xu Mang's eldest wife was called physics, his second wife was called mathematics, the third wife had a Porsche, the fourth and fifth wives had two motorcycles, and the sixth wife was the last one. Own.

wrong!

If his birthday gift customized Fengshenchao arrived, wouldn't he become the seventh wife?

"Humph!"

"Xu Shimei!"

Yang Xiaoman pinched Xu Mang's ear angrily, and said angrily, "In ancient times there was Chen Shimei, and now there is Xu Shimei, you scumbag!"

Xu Mang:? ? ?

Ugh?

What just happened?

Why did he suddenly become a scumbag?

Leave her alone!
