In the night,

Xu mang stays in Xiaoman's dormitory. After all, she will train with her tomorrow. Moreover, the car Xiaoman uses to train hands is also very luxurious. She can use the Mercedes Benz at home directly to practice. Although it is not bad for money, in Xu Mang's impression, the car training should be less than 100000.

"Ah?"

"Can we change it?" Xu mang helplessly said: "others are Santana 2000 or Santana 3000 to practice, you... You actually use the big Benz S600 to train, this is too much, can't dazzle rich like this?"

"But..."

"but this is the cheapest one at home." Yang Xiaoman weakly said: "or tomorrow to pick up a car?"

Xu Mang: sorry,

I'm sorry,

I'm vulgar... The happiness of rich people is unimaginable.

"Forget it... Anyway, dad has a lot of money, so it doesn't matter if you hit one." Xu sighed blankly. However, he was rejecting Xiaoman's car practice in his heart. However, this car really needs to be practiced, otherwise it will be very difficult to go out.

"Big fool?"

"What are you doing?" Yang Xiaoman lay on the bed and said, "I'm a little cold...

" bullshit? "

"How many months has it been?" Xu mang looked back at Xiaoman and said: "can you keep it cold like this? Put your legs in the quilt and show them to whom? "

Yang Xiaoman is so angry,

it's strange that sometimes this psychopath is so gentle that it can melt you, but sometimes it's a pool of mud and can't hold onto the wall at all.

I've already made it clear, mom?

I can't see that.

Alas, my heart is so tired,

I feel that I will not love you any more.

"Are you hiding from me?" Yang Xiaoman thought of what, wearing pajamas, hugged Xu mang from the back, put his head on his shoulder and said softly, "I think you have an opinion on me... Or you are avoiding something."

"..."

"don't think it's crooked." Xu mang said with a smile: "in fact, I am thinking about a problem."

"Well?"

"Tell me, in case I can help you." Yang Xiaoman turned on the air conditioner and adjusted the temperature to 32 degrees. Then he moved a chair and sat beside Xu mang. He said curiously, "what's the problem?"

"About superconductivity of graphene." Xu said.

Yang Xiaoman was stunned for a moment and his face was confused: "did you and I discover the superconductivity of graphene not long ago? What... Is there a problem? "

"No

"I'm looking for new ways to superconduct." Xu said seriously: "to add a new idea to the field of graphene superconductivity."

"What are you...

" what are you going to do? " Xiaoman asked.

"Er..."

"add another layer of graphene to the original two layers." "In the morning, I built the model. Through the model, I found that the stacking mode of three-layer graphene may have an impact on the band structure," Xu said seriously

"And the change in the band structure happens to have an impact on the electronic and optical properties, so... I'm thinking about how to apply it to superconductivity." Xu mang can't help but wipe the sweat on his forehead.

Yang Xiaoman frowned and carefully said, "well... What if there is no connection?"

Hearing Yang Xiaoman's words, Xu mang was stunned for a moment.

Let alone...

I have not considered this point.

"Fool!"

"I remember you said before that superconductors appear in doped Mott insulators described by Hubbard model." Yang Xiaoman said: "you might as well try to start from here, perhaps can give you a new idea."

"..."

horizontal trough!

Is this Xiaoman?

How could she remember everything?

Xu mang has a new view on Yang Xiaoman. What she said is that before the Chinese new year, she casually mentioned the content of a sentence.

"Little man?"

"How do you remember so well?" Xu asked.

"Because you said it, I remember it very well." Yang Xiaoman said with a smile, "can you take me to Jiangda?"

"..."

"I'm on a business trip." Xu mang said with a helpless face: "it's not going to play in the river."

"Oh..." Yang Xiaoman nodded and did not speak.

However,

this situation makes Xu mang a little flustered. Since his cousin talked nonsense with Xiaoman, Xiaoman has become a little different from before. Although he is not very willful, he lacks a little feeling. This is just an outsider with Xiaoman's body.

"In fact..."

"it's OK to go." Xu mang said with a smile: "used to you around me.""Hum!"

"I don't want to go yet." Yang Xiaoman gave a white eye and said silently: "say... Are you hot? I think you're sweating on your forehead

Let alone,

after Xiaoman's warning, I found that the room was indeed very hot.

A feeling of heat.

"Come on

"I'll take your coat off." Xiaoman quietly pulled Xu Mang's coat down and threw it on the table. Then he sat beside him cleverly.

Then, Xu mang stepped into Xiaoman's trap step by step. When all this happened, Xu mang suddenly realized and regretted. He could not help feeling that... A woman who often uses brute force suddenly uses intelligence, which is terrible to unimaginable extent.

The next day,

the next day, Yang Xiaoman was sitting in the driver's seat with cushions. This was the first time she touched the steering wheel after obtaining her driving license. No, it should be the second time.

"Idiot?"

"The brake on the left and the throttle on the right?" Yang Xiaoman asked.

"..."

"yes!" "I know you're scared now, but we're not flustered... This is the first step on your way to drive. Get on with your car!" Xu said with a blank face

As the start button is pressed,

the V12 engine gives a deep roar.

The car is driving slowly,

fortunately, it is relatively stable, and there is no frivolous phenomenon. It is really good for Yang Xiaoman to drive like this. Xu mang also highly praised her for her cleverness and loveliness along the way.

"Well... The road is almost familiar. Can we speed up?" Xu asked.

"Oh..."

tap the accelerator,

at this time, the Big Ben finally caught up with the bicycle in front of him. Fortunately, there were no people on this road, otherwise, he might be scolded to death by the person behind.

Gradually,

Yang Xiaoman's driving skills began to consolidate. After all, he didn't learn for nothing in the driving school, but he didn't drive a car for a long time. As a result, Xiaoman's technology was a little rusty, and the speed was getting faster and faster. In the unmanned place, the speed was as high as 60.

However,

Xu Mang's maximum speed for Xiao man is 80. After all, in places like modu, driving to 80 is considered to be a drag car, and most of them are blocked on the road.

Seeing that the technology began to be stable,

Xu Mang's ideas began to slide, thinking about the Mott insulator mentioned by Xiaoman yesterday.

In fact,

in fact, what Xiaoman said yesterday was not accurate enough. Mott insulator is related to the band structure. From the band structure, it should be conductive, but it is an insulator. It is insulated because of the strong electrostatic interaction between electrons.

Let's take the double-layer graphene superconductor discovered by ourselves and Xiaoman. If two stacks of graphene are stacked together and rotated by a little degree, it will show the insulation effect similar to Mott insulator. No matter how momentum, all electrons carry the same energy.

However, when the voltage is increased and a small amount of electrons are added, the electrons can break the insulation state, flow without resistance, and become superconductors.

Therefore,

there is no problem with our own assumption. As long as we know whether the superposition mode of three-layer graphene will affect the energy band structure, thus forming Mott insulator, then the superconductivity of three-layer graphene will be revealed.

"Can the system... Triple graphene superconduct?"

[according to the systematic identification, whether the three-layer graphene produces superconductivity exchange value: 10000 (physical skills)]

this is a pit,

this dog system is even worse than the too white cat.

After a look at the skill value, Xu mang silently chooses to pay.

It's like buying a peace of mind.

Seeing the answer of the system, Xu mang is more sure of his choice. As long as it is proved that the three-layer superposition energy has an effect on the band structure, superconductivity is simply a matter of finding out, and the rest is the matter of calculation.

However,

we still need a theoretical proof.

At this time, Xu mang logged into the nature official through his mobile phone, found his own paper, read it over and over again. He hoped to derive the theory of two-layer graphene to three-layer graphene, but he failed in the end.

Of course, there is no such thing as failure.

"Lying trough!"

"Is this paper cited so many times?" When Xu mang returned to the interface, he found that his paper and Xiaoman's paper had been quoted a lot. He exclaimed: "Xiaoman... We are very famous in the field of condensed matter physics!"

Bang!

With a loud noise,

Xu Mang's head hit the air bag, and the huge impact almost didn't knock him out.

Boo!There was a white smoke coming out of the hood, and the electric pole was crooked...

"..."

"..."

"Xiaoman, are you ok?" Xu mang regained consciousness and said to Xiaoman, who was full of fear on the side, he said: "it's OK. It's ok... If the car crashes, it's ok as long as people are OK."

Returning to God, Yang Xiaoman glared at Xu mang. The anger in his heart roared at Xu Mang: "Hello! When I was driving, could you not be surprised? I didn't even grasp the steering wheel and rushed to the flower bed on the side of the road. Fortunately, there were no people here. "

Hearing Xiaoman's words, Xu mang smiles awkwardly. He was so excited just now that he forgot that Xiaoman was driving and didn't react until he ejected the air bag.

Finally,

the car was taken to the local 4S store. Xu Mang and Xiaoman lost money for the streetlights in the relevant departments. They went back to school. Xiaoman was still sulking at Xu Mang's startled behavior, so he couldn't help it... Finally, Xu mang begged Yang Xiaoman to go to Jiangda with him, which turned Yin into sunshine.

The next day,

Xu mang drove his precious car and took Yang Xiaoman to Jiangda.

After arriving at Jiang University, he directly found director Lin. then, under his leadership, they came to the laboratory.

"Do you know how to use this equipment?" Director Lin asked.

"No

"..."

"let me talk about it."

Then, director Lin began to operate the extremely complicated equipment in person.

"You see... This is a spatial analysis of the intensity integral of Fermi energy measured with this device."

"This is the theoretical π band of the material along the r-k-m direction in the tight binding model."

"Here is..."

Xu Mang: (° ー)

what is he talking about?

Why are there so many function keys in software?

Why are there so many buttons on the device?

For a long time,

director Lin asked solemnly, "do you understand?"

"..."

"understand... Understand!" Xu mang nods in embarrassment and politeness.

"That's good. I'll go first. There's something else."

As a result,

director Lin left the laboratory.

"Little man?"

"Eh?"

"Did you understand just now?"

"I see. It's very simple. A fool can do it!"
