Chapter 775

At night,

it was still so quiet,

Yang Xiaoman was lying on Xu Mang's back. Today, she had a little too much to drink. A cup of "Long Island Iced Tea" with the original formula directly made Xiaoman drunk. It was a cocktail with alcohol content of more than 40%. Although it was very comfortable, it was not generally high.

Yang Xiaoman: zzz

sleeping Xiaoman doesn't look like a queen at all. At this time, she is like a little sister next door. She is not very tall, but she is extremely cute. Her brother, who is always pestering her childhood sweethearts, either runs around here or makes trouble there. Now they are tired of playing and sleep on his brother's back.

"Why

"I'm so drunk!" Xu mang touched his shoulder and found that it was wet. Fortunately, the car had been driven away by the driver of her father-in-law. Otherwise, according to Xiaoman's degree of drunkenness, as soon as she accelerated, her stomach would not be able to bear it.

"Husband?"

"Husband?"

Yang Xiaoman, who is in the drunken mode, opened his hazy eyes and squeaked, "my husband... Tomorrow... Will buy that bar... I have prepared a lot of money. You... You can discuss with Chen Xi and buy... Buy."

However, Xu mang was a little touched by his words. Although Xiaoman didn't even have an ID card when he was in love with him, he was just a mature child at that time.

Four years have passed... He has grown up and disgraceful, and Xiaoman is like a little child, this change... People can not prevent.

Carrying Xiaoman on her back,

walking on the road home, the memories of the past poured into the brain, as if... She had carried Xiaoman many times. She liked this feeling most, and then she drove her home by electric car. Now think about it... At that time, love was simple and pure like milk.

When he got home,

he left Xiaoman on the bed and set the air conditioner to a suitable temperature. Xu left his bedroom and went to his study. Although he had drunk a lot of wine in the bar, he could still carry it.

During the day, Xu mang has completed half of the theoretical framework of magnetic topological insulator, the remaining half... Xu mang plans to finish it all night, which should not be a problem. With the stimulation of a little alcohol, his inspiration has begun to explode.

According to the calculation and previous experience, bismuth telluride is supposed to be a single crystal film after Mnte electronic structure combination. Although there is nothing about this, it is found that there are seven layers after applying Xu Yang structure formula.

According to the simulation, Xu mang calculated that the material with Mnte electronic structure has Dirac type surface state under no less than two seven layer structure.

It is proved that this is a three-dimensional topological insulator. Finally, according to the magnetic measurement results and the first principle calculation, we can know whether this special material is an antiferromagnetic topological insulator.

"Ah?" Looking at the screen on the screen, Xu mang was immediately interested in this sort of sorting structure, forcing him to continue to study the work that should have been finished.

In the following research, Xu found that this unique magnetic structure can make this material display extremely rich and excellent topological quantum states, and the thin films with odd seven layers are in the quantum abnormal hall phase.

The films with even seven layers are in the axon insulator phase and exhibit topological magnetoelectric effect. The antiferromagnetic topological insulator with topological axon surface state in the three-dimensional bulk phase can be transformed into the simplest magnetic Fermi metal under the external magnetic field.

In short,

this unexpected material structure is really amazing. If manganese element is replaced in a single-layer crystal structure, a class of related materials can be produced. Through reasonable dimension and magnetic control, a lot of topological phases can be realized, such as antiferromagnetic TOPO insulator, wail semi metal, quantum anomalous Hall effect, Axion insulator, etc.

"but wait a minute!"

"Xu mang... You are now guiding researchers to carry out research, rather than one person to study the whole research... Give others a way to live!" Xu mang patted his forehead and felt guilty about his offside. He was killing the future of young people.

What do they do when they have finished their own research? What else can we study? Selfish... Too selfish!

"Husband?"

"Where are you, husband?"

"I... my mouth is a little thirsty... Husband?"

Suddenly,

hearing Yang Xiaoman's cry, Xu mang trotted to the violent airport and asked gently, "what's the matter? Want water? "

"Um...

" drink water... I want to drink water... "Yang Xiaoman is half asleep and half awake, but his face is written with the word" uncomfortable ". Even Xu Mang, a straight man of iron and steel, is also touched by this scene. He hastily brings a cup of warm water, and then holds Xiaoman in one hand and puts the cup to his mouth."Ah

"Open your mouth!"

"The water is coming..." said Xu.

"Hello, I..." this out of tune words came out of confusion.

Xu Mang: ∑ (°Δ°||︴︴︴︴︴︴︴︴|||︴︴︴︴︴︴?

This... This woman drunk, is it too horrible?

But it's not like it's a fake.

Finally,

Xu mang degenerated and became a real beloved wife maniac.

(* ~ 3) (ε ￣ *)

however,

however,

never thought that the nightmare had just begun. In the next six hours, Yang Xiaoman gave full play to his self willed appearance after being drunk, either kicking the quilt or crying for hugging, or even letting Xu mang hold him to take a bath.

If it's not true love, Xu mang may throw it away... No way... This woman is his wife.

The next day,

the next day,

at 9:45 in the morning,

Yang Xiaoman finally woke up. After opening her eyes, she found that she was lying in the bed at home without thinking much. She was holding her forehead. At this time, there were bursts of headache, which made Xiaoman a little upset. She was supposed to hold a meeting in the guild today. This state of affairs... Will not be able to open.

"I..."

"shouldn't I have drunk a cup of black tea?" Yang Xiaoman fell into a cognitive confusion, if it is a serious cocktail, even if it is a cup of black tea... There is a piece of lemon on it, as a result... There is no consciousness when drinking.

Is there something wrong with that bar?

At this time,

Xiaoman thought of some reports in the news. Some gangsters broke things in the bar, and met bad people in other people's drinks? The more I think about it, the more scared I feel. Fortunately, the big fool around me has been accompanying me, otherwise... The consequences are unimaginable.

"Husband!"

"Husband!"

Yang Xiaoman covers the quilt and shouts in the room: "you hurry up to me!"

For a moment,

Xu mang came to the bedroom, glanced at Xiao man lying on the bed, and asked curiously, "what's the matter?"

"Come on

"Call the police!" Yang Xiaoman said nervously: "I drank a cup of black tea and I lost consciousness. There must be something wrong with the bar and I want to murder us."

"What black tea."

"What you drink is Hiroshima black tea, a cocktail made of vodka, rum, gin and tequila, with ice, peppermint, lemon juice and other ingredients." "This originated in Hiroshima, the United States of America, with alcohol as high as 40 degrees," Xu said

"Ah?"

"But... It's delicious." Yang Xiaoman tooted his small mouth and said angrily.

Xu mang said with a wry smile: "I said at that time, you don't listen to it yourself, just drink it up, what can I do?"

Although Xu mang is not wrong, Xiaoman still sums up the crime to him. It is impossible to go to work today. Xiaoman decides to give himself a holiday and have a good rest at home. He is really tired recently.

"Did you stay up all night yesterday?" Yang Xiaoman found that Xu Mang's mental state is very poor, this thick dark circles... What happened this night? He was not so weak before. He had nothing to do for a few nights. As a result, he collapsed this night.

"Say... What's wrong with you?"

"How haggard one night?" Yang Xiaoman asked anxiously.

"..."

"Xiaoman... Promise me not to get drunk in the future." Xu sighed blankly and said with a bitter smile, "you are so... You can make trouble with people. I almost died. Do you know?"

Yang Xiaoman: (~ ~)

in the afternoon,

in the afternoon, Xu mang went to the research institute with his theory. Of course, this time, he did not drive, but let his father-in-law's driver to pick him up. In his present mental state, it is easy to have a car accident, and Xiaoman absolutely does not allow this kind of tragedy.

When we arrived at the quantum materials group office, we found six members sitting together, seemingly studying something.

"Ouch?"

"Are they all there?" Xu mang said with a smile: "very diligent, very hard... Very good!"

"Yao Shui."

"This is the theoretical research report of intrinsic magnetic topological insulator. You can go and see for yourself. According to my above theory, you can synthesize and prepare all the data of this material." "Experimental results of intrinsic magnetic topological insulators grown by MBE and structural analysis index under high resolution electron microscopy," Xu said solemnly

"Curves of Dirac type surface state and Hall resistance with magnetic field in angular resolved photoelectron spectroscopy." "Especially the Hall resistance curve with the magnetic field... The antiferromagnetic to ferromagnetic transition data," Xu said“？？？”

“？？？”

“？？？”

What?

Finished... Finished?

For a moment, all the people present looked at Xu mang with confusion in their eyes.

"Xu..."

"Professor Xu?"

"Completed the theoretical design in such a short time?" Sun Yaoshui asked cautiously, "is it accurate?"

"I don't know."

"Give it a try." Xu mang said wearily, "that's what... The information is here. By the way, there may be new people coming tomorrow and the day after tomorrow. They are graduate students in the materials department of Fuda University. You can help each other."

As a result,

Xu mang left the office.

Looking at the back of Xu Mang's leaving, the six people present looked at each other. All the people who had just been present saw the tired expression and were silent in an instant.

Sun Yaoshui picked up the information in front of him. At this time, the other five people came together. When he opened and saw the contents, the atmosphere of the office fell to freezing point. At this moment, the air had completely condensed.

What they see is not only the calculation process and theoretical proof, but also the greatness contained in calculation and theory.

However,

then came the shock.

"Lying trough!"

"Is that what Professor Xu can do?"
