The person who came was Cao Junhui, the head of the research institute. At first he came to see the situation, but he saw such a heartbreaking scene. What is the situation between these two people? Does research need to be so exaggerated?

"???"

"???"

Damn it!

Who is it?

Xu Mang and Yang Xiaoman looked at the middle-aged man standing at the door in bewilderment, dissatisfied with his appearance for no reason.

"I am Cao Junhui, the person in charge of this research institute." Cao Junhui said helplessly: "Professor Xu and Researcher Yang Yang, can you two separate for a while? I know you are a couple, but is that right?"

Ouch!

This is so embarrassing!

When Yang Xiaoman heard Cao Junhui's words, a blush suddenly appeared on her pretty face. She hurriedly rose from Xu Mang's thigh and said shyly: "Director Cao is not what you see. In fact, Xu Mang is teaching me

Quantum Mechanics.”

""

Teach you quantum mechanics?

This doesn’t require sitting on someone else’s lap to teach, right?

Cao Junhui was helpless, but since the other party was Yang Jian's daughter, he could only smile and say: "Study well, study well."

The words fell,

Cao Junhui walked up to Xu Mang, glanced at the monitor curiously, and asked, "Professor Xu, what are you talking about?"

"Calculate whether the Fermi speed will change when two layers of graphene rotate." Xu Mang said seriously: "We have almost found a way to superconduct graphene, but I guess this method is of little use."

Found it?

No way?

this

Cao Junhui looked at Xu Mang in surprise and asked hurriedly: "Professor Xu, are you sure you have found it?"

"Um!"

"We should have found it." Xu Mang nodded: "But don't be too happy. Even if you find the superconducting properties of graphene, theoretically speaking, it has no effect, just like a chicken in a potted chicken achieves superconductivity. It brings

What comes is only a change in thinking, not a change in technology."

Cao Junhui knew what Xu Mang meant. It was probably that the conditions were too harsh, making it impossible to apply it. However, it could change the way of research and even change the future changes in this field.

but

At present, Xu Mang has not completed superconductivity, so all this is still unknown.

"Professor Xu?"

"How did you achieve superconductivity?" Cao Junhui asked.

"Rotation angle."

"We found a paper that predicted that when two layers of graphene are rotated, forming a certain angle will lead to new electron interactions." Xu Mang said: "We studied the paper carefully and felt that this

What the physicists predicted was true."

The words fell,

Xu Mang showed his latest research results.

"Director Cao, look!"

"Each carbon atom in single-layer graphene has four valence electrons, three of which are hybrid orbitals formed by mixing s orbitals and p orbitals to form bonds with other carbon atoms. The remaining electrons are in graphite

Ene moves on a vertical orbit."

"If the double layers are superimposed and the angle is twisted, a phenomenon will occur, the Dirac cone energy band hybridization effect, and an energy gap will appear on the Dirac cone, causing the Fermi velocity at the Dirac point to be renormalized."

The words fell,

Xu Mang smiled awkwardly: "This is what we imagined."

""

"How did you think of so many?" Cao Junhui asked.

"Rely on model simulation." Xu Mang said with a smile: "Imagination is important, but it is not as direct as model simulation. We used the quantum database to simulate the model and found that when two layers of graphene are superimposed and rotated, they will

A magical pattern of moiré appears, a ripple of light and dark.”

"Moiré patterns are easy to understand. The superposition of two identical geometric patterns will produce such a pattern. However, the emergence of moiré patterns leads to a situation where cells are expanded." Xu Mang continued: "Not only that, because superposition

In this state, the upper and lower carbon atoms are completely aligned, forming an aa arrangement; the upper and lower carbon atoms are staggered, forming an ab or ba arrangement."

"so"

"The peaks and troughs of electron energy state density are formed."

The words fell,

Xu Mang opened the model diagram and pointed to the model above: "This is the model."

Cao Junhui looked at the model carefully, and through Xu Mang's explanation, he really found some clues. This was not theoretical data, but something that could actually be seen.

before that,

It seems that we have reached a misunderstanding and have been wandering in the mode of sandwiching calcium atoms in double-layer graphene, resulting in no progress in research progress.

As a result, the arrival of Professor Xu Mang seemed to have opened up this embarrassing situation.

Although it is all theoretical or model data, it is also a kind of progress.

"Is there any other data?" Cao Junhui asked.

""

"No more." Xu Mang shook his head and said helplessly: "To tell you the truth, I don't have much confidence. Although it is theoretically possible, who knows in reality."

Cao Junhui nodded, and after understanding the progress, he said: "Professor Xu? How long will it take to test the superconductivity of graphene? Based on your current speed."

"Before the laboratory is closed." Xu Mang said.

""

Cao Junhui didn't know if he was complaining, but it sounded like he was complaining. Maybe he was being too preoccupied.

along with,

After a few brief exchanges, Cao Junhui left the laboratory.

"Hello!"

"Are you stupid?" Yang Xiaoman glared at Xu Mang: "What does it mean before the laboratory is closed? What do you make others think? You are too self-motivated. You are Professor Xu, why are you so restless?

?”

"ah?"

"I told the truth." Xu Mang said with a confused face: "It is true that the experiment can be carried out before the laboratory is closed."

"you!"

"What an idiot!" Yang Xiaoman sighed and said in an indifferent tone: "I can't even imagine your future without me. How miserable your life will be. In your situation, I'm afraid you won't be beaten to death."

.”

this

What kind of words is this?

To be honest, life was simply colorful before you were there.

But since I met you, my life has been miserable until death. Not only have I been scolded, but I have also been beaten.

at this time,

Yang Xiaoman slowly opened Xu Mang's hand, sat down on his lap, lay in his arms, and said shyly: "Hurry up, I am your student now, Professor Xu, hurry up and start class."

!”

I

you

Damn it!

Is this crazy?

When Xu Mang heard Xiaoman's words, his hair was tingling. Oh boy, this woman is ready to go to heaven.

"Hey, hey, hey!"

"What's wrong with you?" Xu Mang said with a dark face, "I'm in a relationship with you, and I'm destined to be in jail anytime, anywhere. Good guy, you're adding three more years to the three-year sentence."

Yang Xiaoman pouted and said angrily: "It's not just for you."
