I Don’t Want to Win Lying Down

Chapter 493 One day is enough (23)

also?

What is it called?

After Xu Mang heard Xiaoman say the word 'also', he showed a curious expression, and asked, You...someone in your company is studying fragile topology? This seems to be something about condensed matter physics. Why would a broken company join in the fun?

Yang Xiaoman rolled her eyes, a little unconvinced, and said, What do you call a broken company like ours? It will depend on this broken company to support your laboratory and research institute in the future, okay?

...

What's going on? Xu Mang asked helplessly.

Our company has an employee who graduated from Oxford University. He talked about this at noon today, boasting that his school has research strength unmatched by others in topology. No one in the world can be called the first, only them.

Then you start talking about fragile topologies...Even you can't surpass Oxford University in topologies. Yang Xiaoman said angrily: My mother, I was blown away at that time, and then...

Fired him?

No...then I left. Yang Xiaoman said with a smile: He is also a master's degree from Oxford University, he is quite capable... fired, where to find such a talent, and he knows Less secrets.

oh...

Xu Mang was a little dull,

I thought something big had happened, but it turned out to be this kind of thing.

well?

Are you angry? Yang Xiaoman moved closer to Xu Mang's ear and whispered softly, You are worse than Oxford.

what should I do then?

It's a school...everyone drowned me with a mouthful of spit. Xu Mang turned his head and kissed Xiaoman's cheek, then took a sniff, his face became a little dignified, and he said, Change your perfume?

yes!

It's quite expensive...and limited edition. Yang Xiaoman said, How is it?

Xu Mang felt that this perfume matched Xiaoman quite well.

There was a faint fragrance that matched her overall temperament very well, but...letting Xiaoman go like this was obviously not his character, so Xu Mang decided to play it safe.

Well...

Perfume is good, but people are not good. Xu Mang frowned and said seriously.

words fall,

Xu Mang felt a little cold, and the surrounding air condensed.

Yang Xiaoman: (*￣︿￣)

What's the meaning?

It's been too long to feel disgusted with my old lady?

Hello!

Do you want to die? Yang Xiaoman gritted his teeth and said, Don't think that I dare not beat you up, even if you are a great scientist, you should obey me obediently at home. And your name and handprint!

Fuck,

It's still there?

Xu Mang shrank his head, and said cautiously: Don't talk nonsense...I don't even know what the Xu Yang Treaty is.

However,

next second,

Yang Xiaoman took out a copy of paper from his bag, it was really a copy of the Xu Yang Treaty.

snort!

Don't cook for me yet!

Seeing that Xu Mang was being honest, Yang Xiaoman raised his proud little head and said, Today I want to eat... okra with scallion oil.

oh...

for a long time,

The two sat at the dining table, looking at each other. Three dishes and one soup were the international convention. Although Xiaoman's appetite was small, Xu Mang's appetite was huge, and he almost never brought any leftovers. Xiaoman asked about the adhesive.

Honey...

The raw materials of the adhesive are too expensive. Do you know how much it costs each time I make a bottle of concentrated puree? Yang Xiaoman said helplessly: A BMW 7 Series is gone.

normal.

You don't want to think about how many adhesives you can make from a bottle of concentrated puree... What else do you want if you exchange a BMW 7 Series for a villa? Xu Mang smiled wryly, You can earn some money for others, too. The money has been earned by us, and others will gossip about it.”

All right.

By the way... I plan to invest 10 million in your student foundation. Yang Xiaoman said: Buy a reputation.

what ever.

Xu Mang hardly bothered to ask about this kind of thing. Anyway, 10 million was nothing to Xiaoman. This female capitalist is now a fucking rich thief. While doing financial harvesting, she used adhesives to make money.

In short,

There are various routines.

...

the next day,

Xiaoman went to the company, while Xu Mang stayed at home thinking about fragile topology.

in mathematics,

Xu Mang failed and couldn't find any useful information at all. Then he changed the direction of his thinking, thinking about the problem from the perspective of the quantum state, and used the most important discovery in condensed matter physics-the quantum Hall effect to get to the root of the problem.

The quantum Hall effect is found in two-dimensional conductive materials, but the similar effect in three-dimensional systems is called topological insulation, and the outer conductor is insulated from the inside.

This is a strong topology.

Strong Topology...

Xu Mang suddenly fell into memory. It seemed that the strong topological properties came from some weird properties of the electronic quantum state. What was it?

oh!

Electrons are not completely surrounded by individual atoms, but some of them are delocalized.

well?

What will happen if...some materials have partially delocalized electrons but do not have strong topological properties? Xu Mang came up with a point of view. He didn't know the research results of Oxford University for the time being, but he didn't hinder the proposal. a new concept.

After calculating,

Xu Mang felt that this idea was quite reliable. Although it didn't work, he had a brand new way of thinking.

In Xu Mang's theory, the electronic state can ignore small disturbances, but it is not as robust as the strong topological state. A slight change in the material structure, such as adding a little impurity, can become an ordinary material.

but...

It's useless, it's just fun.

You have a new lawyer's letter, please check it!

the phone rings,

It was Teacher Jiang Dateng calling.

Hello?

Teacher Teng...what do you want from me? Xu Mang asked with a smile.

I knew you must have forgotten, so I asked you to produce the Zhejiang Provincial College Entrance Examination Paper. Teacher Teng said with a smile: It said above... I hope you can produce the Zhejiang Provincial Mathematics and Comprehensive Science Papers this year. The difficulty is... .you figure it out.

ah?

Do you still want to issue a comprehensive examination paper?

Let me figure out the difficulty? Xu Mang was stunned for a moment, then asked cautiously, Mr. Teng... I'm a vicious person, aren't I afraid that the entire army of candidates from Zhejiang Province will be wiped out?

fine.

When the time comes, you will be pushed out. Those media dare not report on you indiscriminately. Teacher Teng laughed.

I...

that's fine too,

Since you are not afraid of death, then I panic!

good!

Ms. Teng...don't blame me for being too ruthless. Xu Mang said seriously, The difficulty of the questions I gave is quite high. It tests the comprehensiveness of the students, especially for those so-called geniuses. serious.

Fine!

I know your routine, anyway, according to your intention, you don't need to go to Jiangda University, just publish the paper and send it to my mailbox. It's a little embarrassing for a scientist of your age to ask you to come here. Teacher Teng said: Let's settle this first, and I won't bother you.

oh...

Snapped,

hang up.

Xu Mang looked at the interrupted phone interface and let out a long sigh.

sorry,

classmates,

requested by your leaders.

thoughts return to reality,

Xu Mang was at a loss for a while looking at the theory he had just written.

It seems...

It still can't get around graphene.

Opening the paper of the Oxford University research team, Xu Mang carefully read the above content. According to their experimental report, Xu Mang suddenly felt familiar. When he saw the data, he felt very strange...Who would have thought is a topological state.

However, the research team at the University of Oxford directly associated superconductivity, and believed that the superconductivity produced by the twisted double-layer graphene is related to the fragile topological state, which is a bit awesome.

Their second paper illustrates a situation where fragile topology is more common than strong topology. At present, about a quarter of materials have strong topology, and studies have shown that electrons in fragile topological states exist in almost all materials.

Then hundreds of thousands of examples of suspected fragile topological phenomena were found in crystal databases.

suspected,

But it's not clear.

Hello?

Professor Fan...can you spare me two days in the lab? Xu Mang said with a smile, It's nothing...just to let others know that I'm still here.

...

the next day,

Fan Zhilong, professor of condensed matter physics at Fuda University, came to the laboratory early, waiting for Xu Mang's arrival.

Yesterday he received a call and was told to borrow the laboratory. Facing Xu Mang's request, Fan Zhilong naturally agreed, not to mention that he is the deputy director of the physics department. Based on his reputation alone, he should consider his request first. .

Ouch?

Professor Fan is so early? Xu Mang came to the laboratory with a bag of soy milk and buns, smiling, and asked, Have you had breakfast?

...

Are you usually quite leisurely? Fan Zhilong said helplessly, Speaking of which, what's going on this time? Did you get into a fight with someone else?

nothing...

Do you know fragile topology? Xu Mang asked.

Fan Zhilong was stunned for a moment: Of course I know this. It belongs to the field of our condensed matter physics. It seems... Not long ago, a certain research group at Oxford University discovered this magical phenomenon in your double-layer twisted graphene. topology.

Fan Zhilong asked: But there is only indirect evidence for this at present, and direct evidence is very difficult, almost... you know, anyway, our professors in the Physics Department of Fuda think it is unlikely.

Yeah?

Xu Mang took a bite of the steamed stuffed bun and said calmly, It's not necessarily...I think it's possible.

...

You...you don't want to use the laboratory to study fragile topological states? Fan Zhilong said in surprise: This is different from strong topology, which will show measurable phenomena, while the measurable effects of fragile topological effects are very weak. , so weak that it is almost negligible.”

The Oxford research team only found indirect evidence, which is suspected of fragile topological phenomena. Fan Zhilong said, Have you thought it through?

Actually, this is not a very difficult problem. Xu Mang smiled: The research team at Oxford University has already discovered it, but they didn't notice it, just like when I discovered that double-layer twisted graphene can superconduct, but I didn't notice it. to a suspected topological state.

Fan Zhilong didn't say a word. Since Xu Mang thought there was no problem, then there was really no problem. After all... His name was Xu Mang, which meant full of miracles.

Is two days enough?

How about I spare a little more time? Fan Zhilong asked, How about four days?

Xu Mang took a sip of soy milk, raised his head and smiled, One day is enough.

Fan Zhilong:? ? ?

As I write this, a voice appears in my head...isn't the game fun? ? ? Failed to resist the temptation...囧
