soon,

Xiao Zheng got the document sent by Xu Mang. He downloaded the document and opened it. There were three full pages of content. He had not seen the content yet, but the full sincerity made Xiao Zheng stand in awe. Sure enough, Professor Xu was very good at everything he did.

So attentive.

When Xiao Zheng checked the content, he couldn't help but be shocked by Xu Mang's ideas. Although it seemed to be three full pages of content, the calculation process occupied two and a half pages, leaving only half a page for the theoretical framework. However, this simple half page

The page is the essence.

very short

But they are all the best!

I had also considered the strongly correlated electron system at the beginning, but not as thoughtfully as Professor Xu. Especially under the strong interaction between electrons, Professor Xu actually considered the two-dimensional high mobility insulating state phase transition and quantum phase.

Variable and quantum critical phenomena, and charge density waves in one dimension.

Xiao Zheng called two of his colleagues and briefly explained the situation. Soon the two colleagues rushed into the office.

"Show me!" One of the male colleagues said hurriedly: "Where is it? Show me!"

Xiao Zheng turned his laptop screen in front of the two of them.

moment,

The two male colleagues began to breathe rapidly, and at the end, one of them couldn't help shouting: "So strong! Why didn't we take this into consideration?"

"Don't say it yet"

"It seems very simple after Professor Xu explained it!" another laughed.

When Xiao Zheng heard this person's words, he said with a dark look on his face: "That's Professor Xu. Of course the stuff he created is simple."

soon,

Based on this theoretical framework, the three began to conduct experimental designs for the controllable insulating state of graphene, which was similar to what Xu Mang thought, but there was a slight difference. They did not use boron nitride, but used a certain copper-based material negative.

.

However, because of this, it brought a lot of trouble to the experiment. The three found that although the lattice constant became very large, they could not control the intensity of the electron interaction in the system, and the change in the effective mass of the electron was also extremely limited.

Not only that, when the interaction between electrons is extremely intense, not every electron is associated with other electrons. When an electron moves, it is difficult to be restrained by other electrons, causing graphene to become a semi-insulating state.

There is absolutely nothing wrong with the theoretical framework. After all, it was given by Professor Xu. There is only one reason why it is wrong, that is, the copper-based material substrate may not match the hexagonal honeycomb lattice of graphene.

final,

With the help of materials science database and intelligent synthesis software, the three people found a crystal material, a hexagonal crystal system.

"Huh?"

"Isn't this Professor Xu's three-layer graphene superconducting material?" Xiao Zheng was surprised to find that with the help of the database, the material data obtained without exception pointed to a material called boron nitride.

.

The three people hurriedly looked at the paper on three-layer graphene, and got a hint of inspiration from its structure. They made exactly the same superposition method, with three layers of graphene sandwiched between boron nitride, but two more switches were added before and after.

Different from experimental superconductivity, Xu Mang's superconductivity experiment was completed at a temperature close to absolute zero, while Xiao Zheng's experiment was completed at room temperature.

According to practicality,

Xiao Zheng's experiment is more widely applicable than Xu Mang's superconducting experiment. Xu Mang's is theoretical research and provides a theoretical concept. Simply put, Xiao Zheng and others' laboratory is based on Xu Mang's theoretical concept.

middle.

"Let's get started!"

Xiao Zheng looked serious and said to everyone present, including a dozen master's students: "Work harder, we will complete this research today."

at this time,

Yang Xiaoman drove his smart car and drove Xu Mang to the local furniture market in Magic City. The two of them wanted to buy a batch of furniture. After all, they still had to stay in school for another year. After Xiaoman graduated, they could buy their own furniture.

own house.

actually

It can't be said to be a purchase. Several real estate companies owned by Yang's father are extremely influential in the whole range. It's just that his high-tech industry has overshadowed his real estate.

"The big bed, table and chairs need to be replaced. It's so ugly." Yang Xiaoman drove the car and said seriously: "We also need to put a bookshelf in the place where you work. By the way, there are also lamps.

It’s too dazzling at night, so choose a soft light source to avoid hurting your eyes.”

Listening to Xiaoman's words, Xu Mang was a little confused and couldn't understand it at all. Anyway, just stay with him and he won't pay.

Xu Mang is in a miserable state now. All his money was thrown into the laboratory, and all his salary as a professor was taken away by Xiaoman. Even his private money was confiscated. He was only given 3,000 yuan of pocket money every month, and he often had pocket money.

Within a week after the money was issued, it was all spent. Looking back, I have no idea where it was spent.

He already had a job, and it was a bit shameful for him to take money from his family again. Finally, in desperation, Xu Mang could only extend his claws to Xiaoman's satchel, but every time he opened the bag, there was always only one piece of paper in it.

One hundred dollars.

no way

I want to take a hundred yuan.

In fact, Xiaoman already knew what Xu Mang was going to do when he got up in the middle of the night, and the 100 yuan was deliberately reserved for him. The reason for handing over his salary at first was to curb Xu Mang's habit of mindlessly spending money, and he was stupid enough to charge a lot of money at once.

Tens of thousands, and then after playing the game for two weeks, I changed to another game.

It seems that the effect is good so far. He no longer spends money in the game. He has become a casual player from the gold warrior in the past. He has even effectively controlled Xu Mang's smoking addiction. Because he has no money to buy cigarettes, in fact, think about it, this big idiot can't spend that much.

Much money.

He is a professor in the Department of Physics at Fuda, and he is also the deputy director of the Department of Physics. He can be reimbursed for gasoline, meals, business trips, everything.

"Talk"

"Have you brought any money?" Yang Xiaoman asked intentionally or unintentionally.

"How can I have money?"

"All the salary given by the school will be given to you." Xu Mang said helplessly: "I have been reduced from a golden leaf to a hard-working person."

"snort!"

"Then you should smoke less." Yang Xiaoman rolled his eyes and said angrily: "Don't you understand why I turned in your salary? Every time I see you playing games, you are either on the way to recharge, or just now

Of course you have to correct your bad habit before spending money after recharging."

Xu Mang smiled awkwardly, this was indeed the case.

There is no way,

If you don’t have the technology, you have to make do with money.

Arriving at the underground parking lot of the shopping mall, Yang Xiaoman took Xu Mang and walked inside the shopping mall.

Accompanied by Xiao Man, Xu Mang came to the place where beds were sold, and a pretty decent young lady picked them up.

"Sir, ma'am."

"What price do you want for the bed?" the shopping guide asked.

"have no idea"

"The most expensive one." Yang Xiaoman thought for a moment and said seriously: "The most expensive one!"

"OK."

Immediately afterwards,

The shopping guide led Xu Mang and Xiaoman to the so-called most expensive bed. Xu Mang heard what the shopping guide said and didn't understand what duxiana was, but the price quoted by the shopping guide almost made Xu Mang pee.

Two hundred thousand?

The mattress costs 200,000?

Stealing money openly?

Yang Xiaoman doesn't care about 200,000. He engages in activities with this big idiot every night. The next morning, his whole body is sore and weak. It's because the bed he slept on is made of wooden boards. In addition, this idiot is like a lunatic.

If you don’t know how to cherish it, you will die.

Just when Yang Xiaoman was about to pay, she received a call from her sister and left for a short time.

"Can I go up and lie down for a while?" Xu Mang asked.

"Can."

Xu Mang took off his shoes and lay on it for a while, not to mention the comfort that money brings.

"gentlemen?"

"How do you feel?" the shopping guide asked.

"Um!"

"Very good." Xu Mang nodded.

At this time,

The shopping guide smiled and said: "Our sofas are also very good. Would you like to try them out? Now we have a discount. You can get a 10% discount on beds and sofas."
