I Don’t Want to Win Lying Down

The back is on fire?

Is there still such an operation in this year?

Xu Mang was stunned when he heard that, he felt that the person in front of him was fooling himself, if his back could be hot... Do you think everyone is called Beckham? Are they all the 'Bei Ying' in World Football?

Who are you? Xu Mang said angrily, Do you think I'm a fool? How could my back be popular? Without the embellishment of my flourishing beauty, isn't this... funny?

Shan Guoyi:? ? ?

ha?

This...this feels...a bit different from Professor Xu in the impression and in the photo.

The real him seems to be quite...what the heck.

It's a bit of a bad word.

Professor Xu?

You... forgot to introduce me, I am Shan Guoyi... I know Professor Hua Yanfeng. Shan Guoyi said seriously: Although I am older than you, I am far behind you in terms of academics.

oh...

Old Dan! Xu Mang had a good impression of Comrade Shan Guoyi. First of all, he was more modest and much better than those Europeans and Americans. He said with a smile, What's the matter? What's wrong with you?

This...allows me to keep a secret, and I will know later. Shan Guoyi smiled, and after a while he said seriously: Professor Xu... Regarding the prediction particle-axion, what stage have you reached now? ?”

Xu Mang thought for a moment, then said calmly, Theoretical stage.

Although no progress had been made, he had to pretend to be unfathomable, but... Shan Guoyi was an old fritter in the rivers and lakes, and instantly knew that Xu Mang hadn't achieved any results so far.

Forty-two years of prophecy, it can be done so easily. Shan Guoyi said seriously: Professor Xu take your time, with your attitude towards scientific research, I believe that miracles will definitely happen in the near future.

Confused, Xu Mang watched Comrade Shan Guoyi leave.

No way?

what's the situation?

Could it be... Shengshi Beauty not only burns single women,

By the way, it also ignited the greasy middle-aged man?

What's the matter?

I don't understand at all...

for a long time,

When Xu Mang returned to the apartment, he found that Xiaoman had arrived early. There was no way... he was delayed in the research institute for too long.

Ouch?

Student Xiaoman is so hardworking today? Xu Mang knew that he was coming back late, so he hurriedly prepared the witty words he had thought up before, and came to the kitchen with a smirk. He knew that as long as he gently hugged Xiaoman from behind, Say a few words in her ear, and she will instantly go limp.

By the time...

It's not like he looks happy.

as expected,

When Xu Mang completed this set of movements, Xiaoman surrendered in an instant, and he was also disappointed... One movement and a few witty words were taken down by this big idiot in a daze.

snort!

By the way... I have a question, I hope you can answer it in person. Yang Xiaoman said with a blushing face, I saw this question on the Internet. If I fall in love with my mother-in-law Into the water, who will you save?

You can't swim! Yang Xiaoman did not come up with a fatal condition.

Xu Mang: 囧

Send a proposition!

This is definitely a proposition!

Logically speaking...if the daughter-in-law asks this question, then she will definitely save the daughter-in-law. If the mother asks this question, then the mother will definitely be saved. If two people ask this question at the same time, basically this will not happen.

but...

There is a bug in Xiaoman's rhetoric, which is a language loophole.

Save my mother! Xu Mang said firmly.

words fall,

Yang Xiaoman was so angry that he exploded, but he couldn't attack, he remained silent and his face darkened.

What does your colleague fall into the water, what does it have to do with me? Xu Mang said angrily, Stop using TikTok in the future, I think you've lost your mind.

same...

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 when he found it. Fortunately, the environment at that time gave him a lot of skills. It's worth it, otherwise it's a miserable day.

By the way...

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.

certainly,

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 1929. 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...more than 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 forty-two-year-predicted axe, derived eighty Weyl fermions from many years ago, 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.

God!

Could this guy drive himself crazy?

well?

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.

Hello?

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, then began to think about the physical properties of Weyl semimetals, and made reasonable speculations based on theoretical predictions - Weyl fermion states.

at this very moment,

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?

snort!

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:? ? ?

well?

What happened just now?

Why did he suddenly become a scumbag?

Leave her alone!

Xu Mang's thoughts returned to the Weyl semimetal. According to the prediction theory of the Weyl fermion state, the following points can be basically determined. First, the Weyl cones with opposite chirality appear in pairs in the body energy band structure. Second, there is an open Fermi surface connecting the surface projections of two Weyl points on the crystal surface.

This Fermi surface is called a Fermi arc...

The three different chiral Weyl fermions are separated from each other, which will lead to a peculiar chiral anomalous effect.

basically,

If nothing else,

These three cases are probably the 'strange' physical phenomena of Weyl semimetals.

weyl cone,

Fermi Arc,

chiral anomaly...

According to these three characteristics, find the corresponding material.

half past nine in the evening,

Xu Mang worked out the basic theoretical framework of Weyl semimetals, which were actually some derivations from Weyl fermion states.

after taking a shower,

After putting on his pants, Xu Mang was about to go to bed when he found that the bedroom door was locked, so he knocked on the door hastily.

Little Man?

Open the door! Xu Mang shouted.

Do you know what's wrong? Yang Xiaoman said angrily.

ah?

Oh...I was wrong. Xu Mang remembered what his cousin-in-law said at this time, facing his daughter-in-law, just admit his mistake unconditionally.

well...

It's time to visit relatives.

moment,

the door opened

Xu Mang slipped in, and got under the blanket before Xiaoman could react.

It's safe!

Little Man?

Well?

By the way, why are you suddenly angry? Xu Mang asked curiously, Did a relative come?

Yang Xiaoman rolled her eyes, and said nonchalantly: Why are you counting so carefully? Could it be that before you met me, you counted other people's cycles every day?

Hearing these words, Xu Mang suddenly felt something was wrong.

It's over!

It's all over now!

When a scholar meets a soldier, he can't explain why.

this night,

Spent in blood and tears and sweat.

...

the next day,

Xu Mang walked towards the Condensed Matter Physics Laboratory with his satchel on his back.

well?

Professor Fan is so early? Xu Mang put down his satchel with a smile, drank soy milk and asked, Have you had breakfast yet?

have eaten.

By the way, what do you want from me? Fan Zhilong asked.

Give!

Xu Mang threw out a promised manuscript from his satchel, and said with a smile, All the contents are on it.

Fan Zhilong was stunned for a moment, picked up the manuscript and opened it. In less than half a minute, his heartbeat began to speed up, his breathing became rapid, and the thoughts in his brain had been drained. secondary body.

this...

you...

Fan Zhilong raised his head and looked at Xu Mang in horror: Weyl semi-metal?
