I Don’t Want to Win Lying Down

Hello?

Professor Gu? Xu Mang's laughing voice reached Lao Gu's ears. From this hearty laughter, there was no sense of tension at all.

Professor Xu...are you okay? Professor Gu asked hastily.

Let me confirm some things with you...don't be so nervous, it's not that I can't solve it. Xu Mang explained: I found a problem in your theoretical model...whether angles can be widely observed in magnetic materials? The singularity of magnetoresistance?

...

Singularity of angular magnetoresistance? Professor Gu asked curiously: We...do not seem to have observed the existence of singularity of angular magnetoresistance.

oh...

Xu Mang was silent for a while, and said seriously: I'll give you a standard theoretical model tomorrow morning, goodbye...

Snapped!

hang up the phone,

At this time, Professor Gu looked a little surprised. He was confused by Xu Mang. Suddenly, he made a phone call that was hard to guard against. He asked a very strange question, whether the singularity of angular magnetoresistance can be widely observed in magnetic materials. ...

How to say?

What did Academician Xu tell you? Lao Fang, who was sitting in front of Professor Gu, looked at his friend curiously and asked hastily.

Professor Xu asked me whether the singularity of angular magnetoresistance can be widely observed in magnetic materials... My research team and I have not found the singularity of angular magnetoresistance. How could he ask this question? Gu The professor frowned, with a slightly strange expression.

words fall,

Professor Gu added: By the way, we can get a brand new theoretical model the next morning.

Old Fang had question marks all over his face.

...

Magic City,

Xu Yang Research Institute,

Xu Mang was staying in his office. According to Professor Gu's research content, Xu Mang reconstructed a brand new theoretical framework. The brand new theoretical model was quite different from Professor Gu's.

So Xu Mang called him to confirm some problems.

In Xu Mang's theoretical model, new reactions and symmetries appeared. Xu Mang predicted that for crystals composed of cerium, aluminum, germanium, and silicon, when the temperature drops to a certain level, about 5K, when the magnetic field along When the high symmetry direction of the crystal is precisely aligned with an angle of one degree, the resistivity of the crystal will increase sharply.

Just like the hands of a watch, the twelve o'clock and twenty-four o'clock timekeeping, the hands have no other position, only when the direction or vector of the magnetic field is in line with the high symmetry axis of the crystal structure of the material, such resistance occurs.

When the magnetic field rotates more than one degree from that axis, the resistance will drop sharply. This is the result obtained through calculation. Although it is not yet known why this situation occurs in the model and the reason for it, but Xu Mang's next step is to solve this problem.

Look for data with the same situation in traditional materials, and whether this sharply enhanced property also exists in other materials.

According to various materials and Xu Mang's precise calculations, a seemingly correct conclusion has been drawn. According to the theoretical model, this material composed of cerium, aluminum, germanium, and silicon is not as sensitive to magnetic fields as traditional materials. Instead of responding to individual components, they respond to absolute vector directions.

However, it is only a special state that can only be realized under special conditions, and the enhancement is limited by the height of the magnetic field along the crystal axis, indicating that symmetry plays a key role. However, Xu Mang did not explore the magnetic moment arrangement in depth, because it needs Conduct powder neutron diffraction research experiment on magnetic moment.

experiment?

Sorry...not available!

After all, he is an expert in theoretical physics, a giant in thought, but a dwarf in action.

However, through his new theoretical model, Xu Mang discovered that this new concept plays a vital role in understanding the topological properties and magnetic domain properties of materials, so Xu Mang reconstructed a 2.0 theoretical model on the basis of the original one.

Among them, the spontaneous symmetry breaking caused by the ordered pair of magnetic moments is related to the magnetic field and the topological electronic structure. If the direction of the magnetic field is precisely controlled, uniform and orderly switching between low-resistance and high-resistance states can be achieved.

Next,

It was to solve a doubt in Xu Mang's mind, and to solve a question I asked Professor Gu before, whether the singularity of angular magnetoresistance can be widely observed in magnetic materials.

Through model analysis,

Singular responses do exist in other materials due to the electronic structure in magnetic materials with a small amount of free charge, which occurs in point-like electronic structures, while allowing electron momentum to depend on the structure of the magnetic order.

Hello?

Come here... I have something for you. Xu Mang called Wang Ai with a very serious tone.

soon,

Wang Ai ran to Xu Mang's office and asked curiously, Academician Xu...do you have any tasks?

Help me complete the first-principles electronic structure calculation. Xu Mang handed over a document, and said to Wang Ai, Hurry up a little bit, I'll use it urgently... This is an assessment for you, if you can't handle it If so, I might consider letting you stay in the gravitational wave detection laboratory, because you don't have this ability to play in other fields.

don't even say,

At this moment Wang Ai was full of fighting spirit.

Watching Wang Ai leave, Xu Mang couldn't help stretching. The next step was to wait for the calculation results to rule out changes in the atomic arrangement, that is, structural phase transitions, as the cause of the change in the resistivity of the cerium-based material.

certainly,

If the result is different from what he predicted, then it's over... It's completely cold, but Xu Mang is very confident in himself.

In the past, Xu Mang might write a proposal, formulate the next experimental steps, and do all the work by himself, except for the experiment... But now Xu Mang only provides a theoretical model, and the rest, even if he knows won't do it.

At this point, Xu Mang has undergone a qualitative change from being a professional scientific researcher to training a scientific researcher.

Logically speaking, it was a relaxed stage now, but Xu Mang felt pressure was pressure, some came from the environment, some came from others, but more of it was his own uneasiness.

Xu Mang is now very worried about a situation. Wang Ai, Dong Yu, Zhang Yapeng, including Hu Jie, who had been an intern here for half a year, Xu Mang is worried that these people will leave here. Of course, the so-called departure does not simply leave the Xu Yang Research Institute. , but to leave Huaguo.

You can say that,

Wang Ai, Dong Yu, and Zhang Pengyu should be regarded as Xu Mang's most proud disciples. From the moment the gravitational wave laboratory was built, these three people followed him. There were constant problems at the beginning, but they could not be said to be authoritative figures. , that can be considered a top existence.

Dare I say that,

Any research institution is a very sought-after commodity. Xu Mang is happy to see them continue to go up, or take the lead, but he doesn't want to see them leave Huaguo and go to a foreign research institution, never to return. return.

Xu Mang was very restrained in the number of his income. Even if Fuda Physics Department sent intern graduate students, Xu Mang would at most just take a look and point out the mistakes. He was worried that the talents he cultivated would never come after going abroad.

How to solve?

I'm sorry... The reality is mostly like this, and Xu Mang can only resign himself to fate.

Hello?

My wife...it's over. Xu Mang received a call from Xiaoman and asked curiously, Did you send another batch of supplies?

Um...

Husband...one of my high-level technical employees was poached. Yang Xiaoman was very depressed, and said silently: I have already worked to the position of supervisor, but suddenly left. Last month He also proposed a technical policy to me, and the news of his resignation reached my ears yesterday.

words fall,

Xiaoman said helplessly: It's so cruel... It was clearly planned, but in the end, he pretended in front of me that he could go through fire and water for the company.

husband?

Is it the person who is really determined to leave, the sound of closing the door will always be the smallest? Yang Xiaoman said silently: I thought of a sentence... leaving with great fanfare is actually a temptation, and the real departure is no farewell , The people who have always shouted to leave at the top of their voices are the ones who finally pick up the glass shards that fell on the floor and bend down to pick them up one by one.

As for those who really want to leave, they just choose a sunny day, wear the most ordinary clothes to go out, and then... never come back. Yang Xiaoman sighed, helplessly Said: I finally know now... People who really want to leave are so stingy that even saying 'goodbye' feels like a waste of time.

husband?

When you When you leave me, can you tell me and see me for the last time.

at this time,

Xiaoman's tone was filled with a kind of tenderness and tenderness.

...

Don't make trouble!

Give me ten guts, and I don't dare to divorce you. Xu Mang said with a dark face, Honey...are you early menopause? Is your menopause early too? Almost early Twenty years, or are you bored recently... have you lost your mind by watching soap operas?

As soon as the voice fell,

Yang Xiaoman exploded on the spot, and angrily shouted at Xu Mang: Can you say a few words? When you are so moved, shouldn't you comfort me? It's all right now... I finally laid the groundwork for you The atmosphere is gone!

Xu Mang: 囧

Blame me?

Ahem...

What do you want to eat tonight? Xu Mang asked cautiously, Uh... how about the army hotpot?

don't want!

I want to eat... hamburger meat. Yang Xiaoman's appetite has recently developed towards Japanese food, and he especially loved the so-called sashimi before.

okay!

I'll make it for you tonight.

Snapped,

Hang up the phone directly,

Xiaoman was not given any chance to speak.

call...

This woman is crazy! Xu Mang said with emotion.

At this time,

Silently, he took out a notebook from the drawer.

On XX, XX, sunny day.

I sat in a chair and thought for five minutes, my heart beat 387 times. I really couldn't figure out why Xiaoman became more and more stupid, and if he continued to be so stupid... he would break away from the lowest standard of human IQ.

put pen to paper,

Close the notebook, on the cover it says 'Yang Xiaoman's Wonderful Life'.

However,

Then Xu Mang's brain twitched, and he threw it directly into his handbag.
