I Don’t Want to Win Lying Down

Xu Mang suddenly felt a little helpless. Perhaps the worry was unnecessary. Although the Quantum Research Institute under Fermilab successfully proved the Klein tunneling phenomenon using graphene, the evidence was still insufficient. If this evidence was used to explain Klein's tunneling, regardless of whether other people can accept it, he will never pass it.

As reported by the Quantum Institute under Fermilab, they investigated the tunneling properties of strained graphene monolayers driven by a perpendicularly acting magnetic field, given the transmittance across a magnetic barrier by the transfer matrix.

It is found that in small-angle scattering, unlike Klein tunneling in an electric barrier, a magnetic field can trap electrons in a strained magnetic barrier, and the presence of strain can significantly increase directional transmission as long as the incident energy is not too large. Rate.

When the injected energy is large, the effect of strain is completely removed, so that strained graphene and ideal graphene have almost the same tunneling properties.

In general,

This is the tunneling property of graphene in a magnetic field under stress.

sorry,

I cannot accept such evidence!

Xu Mang was full of disdain for this, obviously... This is a manifestation of eagerness for quick success. It is estimated that knowing his existence accelerated the speed of research, which led to such a problem, and there was a lack of definitive evidence.

Professor Xu?

Do you have any good ideas? said the young graduate student cautiously. Physicists in the Western world are happy about this now. They think that in the field of physics, you are no longer the one who keeps Undefeated, now you can be defeated.

Xu Mang froze for a moment, then asked curiously: This...does this mean that you can defeat me? Isn't it the tunneling properties of graphene in a magnetic field under stress... What's the big deal, no matter what others want I don’t want to admit it, anyway, I don’t admit that this evidence proves Klein tunneling.”

But... the young graduate student said: The whole world thinks so, and we haven't even found suitable materials so far, so it's too difficult to surpass.

Who said that?

I don't agree! Xu Mang said seriously, Isn't it just to find a suitable topological insulator material, just kidding... There is never such a thing as a difficulty in my dictionary, just close and open your eyes!

...

Hearing Xu Mang's words,

The young graduate student smiled wryly. No one can brag about being awesome, but only Professor Xu Mang can do it. There is no way... He is good at making awesomeness come true, but just now this bragging was a bit too much.

Ahem!

Professor Xu Mang, how sure are you? the graduate student asked cautiously.

grasp?

One hundred and twenty percent. Xu Mang said indifferently: Go back now, and tell them by the way, don't have any worries, I'm here for everything... Don't be afraid, let's talk about the mechanism of super-large black holes What is the impact of the research report?

The impact is extraordinary.

It has passed Nature Astronomy. The graduate student said excitedly: We don't know why it is so fast, maybe it is your reason, but...we have all been on the school's homepage.

oh...

Keep working hard! Xu Mang said casually, then turned on the computer, and continued, Help me close the door when I go out.

moment,

Xu Mang was the only one left in the office. He was not at ease now. People all over the world who opposed him were having a carnival, and suitable topological insulator materials were nowhere in sight. What should we do?

Xu Mang fell into silence. According to the research of the previous two days, basically this topological insulator material is a hybrid material, that is, the interior is an insulator, but the surface is metallic, and under certain conditions, the surface can be transformed into a superconducting material.

This greatly increased the difficulty. At first, samarium hexaboride was chosen as the material, because samarium hexaboride meets the conditions that the interior is an insulator, but the surface is a metal, and the surface allows electrons to move freely, while the direction of electron movement is locked in on an intrinsic quantum property called spin.

However, its surface does not have the conditions to realize the Klein tunnel. Either a new topological insulator material is selected, or the samarium hexaboride material is specially processed. Each choice is very difficult, and it is almost a desperate situation with no turning back.

but...

Xu Mang was more inclined to the second option, which was to perform special processing on the samarium hexaboride material.

Samarium hexaboride... How the hell can it be transformed into a superconducting material? Xu Mang couldn't think of a solution. It is simply not something that humans can solve. It is difficult to turn a topological insulator material into a superconducting material. It's no less than a short, flat and shriveled Xiaoman turning into a tall and curvy Xiaoman.

My God!

It's so difficult! Xu Mang sighed. To be successful in this area, he must be proficient in topological physics, condensed matter physics, spectroscopy, and theory at the same time, but...he has clearly reached the top of all of them, Why still can't solve the problem.

Hello?

Director Fang?

Is there anything you can do with me? Xu Mang received a call from Fang Jun, the director of Fuda's Department of Physics, and said weakly, I'm rather desperate now. To use an Internet slang... my baby is in my heart, but if my baby doesn't say it, I'm too Crap.

...

Is it about the Quantum Research Institute under Fermilab successfully proving Klein tunneling using graphene? Fang Jun said indifferently: It's normal to fail once in a while, after all, people can't go on smoothly all the time.

It is true to say so, but I am particularly dissatisfied.

Speaking of Director Fang?

You didn't come to me just to enlighten me, did you? Xu Mang asked curiously, I'm a world-renowned scientist now, and I'll be able to make you equal in the second half of the year, and we'll all be academicians of the Academy of Sciences by then.

You kid...

Forget it. Fang Jun smiled bitterly: The principal asked me to ask you, do you still need graduate students to do research with you?

ha?

This... Is this really a training institution?

Come whenever you want?

Ahem!

I don't need it for the time being. Xu Mang said with a smile: That's right... I will charge double the fee in the future, eat my drink and use mine, and I will pay them... Director Fang In the future, every graduate student who comes to me for an internship will be charged 500,000 yuan per year, and the school will bear half of the research topic.

...

This matter... you can talk to the principal in person, if he agrees, I have no objection. Fang Jun said with a smile: Then... hang up first.

Snapped!

Hang up the phone directly.

Xu Mang hurriedly called the second grandfather, asking about the increase in money and the sharing of scientific research funds, let alone... for a while, he didn't know how to speak, and when he beeped, he hung up directly. Xu Mang needed to organize his language.

two minutes later,

Xu Mang dialed the phone again, and soon the death call went through.

Hello?

Hey hey...Second Grandpa? Xu Mang asked with a smile, How are you doing recently? Are you going to take care of yourself?

...

I was in good health, but your kid called me, and I have a little brain congestion. The second grandfather said angrily, Have you thought of some bad idea again?

Ahem!

Second Grandpa... am I this kind of person? Xu Mang said cautiously: Then what... I'm here to discuss with you. Regarding the graduate students who come to my research institute for internships, I think... I will give you money in the future, and I was asking for money in the first place, but this time I am just testing the waters.

Regarding the matter of giving money, the second grandfather knew about it before, and he was quite puzzled before. Xu Mang didn't call to pay, but now the call finally came.

Um!

I know about this. Second Grandpa nodded.

Then what...

Second Grandpa, I think you've made a mistake. Xu Mang said seriously, I mean you will need to add money in the future, don't be angry, don't be angry... listen to my explanation...Second Grandpa, you understand my family's situation , Xiaoman, this prodigal bitch is too good at prodigal, if I don’t earn some money to support my family, I’m afraid our young couple will starve to death in the future.”

Hearing Xu Mang's words, the Second Grandpa almost didn't go mad with anger. This guy really opened his mouth and couldn't help but laughed and cursed, You boy... I'm your Second Grandpa, and I don't know about your family's situation yet? Brat. ..Your father-in-law told me how much your wife earned last year.

Whoops...

This shit,

Xu Mang was a little embarrassed, and said with a smile, Then...the matter of adding money?

Don't even think about it!

Snapped!

Hang up directly.

Xu Mang was stunned for a moment, thinking that he had an auditory hallucination, and after confirming again and again, he was sure that he was hung up by the second grandfather.

oops...

Stirring, I can't say what, I'm making trouble.

Xu Mang was so angry that he had no choice but to call Xiaoman and ask her to communicate with Second Grandpa. Compared with himself...Second Grandpa seemed to love Xiaoman more, basically there was no problem, but unfortunately, Xiaoman directly Rejected.

never mind,

Let's talk about it later, let's solve the problem first.

Sitting in the office with his legs crossed, let alone... In his confusion, Xu Mang thought of Xu Yang's structural formula.

perhaps,

Using Xu Yang's structural formula, you can get a little inspiration.

After recalculating the crystal structure of samarium hexaboride, Xu Mang seemed to have discovered something incredible. He found a material with the same crystal structure as samarium hexaboride, called yttrium hexaboride...with good chemical properties. Excellent physical, chemical and electrical properties such as stability, electrical and magnetic properties.

well?

That's wrong! Xu Mang's brain had a short circuit, samarium hexaboride and yttrium hexaboride... Which material is used as the base material?

finally,

Xu Mang made two attempts. The surface layer of yttrium hexaboride was covered with a layer of samarium hexaboride film. The other solution was to cover the surface layer of samarium hexaboride with a layer of yttrium hexaboride film. Theoretical calculations yielded two completely different results.

finally,

Xu Mang chose the solution of covering the surface layer of yttrium hexaboride with a thin film of samarium hexaboride.

In theoretical calculations, when the entire assembly was cooled to a few degrees above absolute zero, yttrium hexaboride became a superconductor, as did the metal surface of samarium hexaboride due to its crystal structure proximity.

In this way, it conforms to all his previous preconceived concepts.

but...

A bit expensive!

Xu Mang thought for a while, it's time for the 'vampire' Yang Xiaoman to vomit blood once!

(°ー°〃) confused~

(ノへ￣,) Feeling sad!

well...

Looks like tonight is going to be another bloodbath!
