Magic City,

Xu Mang took Song Xiaoxi to the Xu Yang Research Institute, and the intense work began, of course, in order to work smoothly, Xu Mang re-optimized the list of members of the research group, and the current team for the preparation of quantum materials is five people, and his group is a full nine people.

In the latest experimental work, in addition to the superconductor bands placed on the surface of the quantum anomalous Hall insulator to form a heterojunction proposed in the theoretical model, Xu Manghai prepared nanoscale superconducting probes with the same superconductor on the same device to characterize the contact between the quantum anonormal Hall insulator and the superconductor.

Using the superconducting nanoprobe structure, the differential conductance of superconductors and quantum anomalous Hall insulators under DC bias was measured.

If the data proves that your guess is correct, then you can continue to the next step of the experiment, otherwise the experiment can be reversed.

And Song Xiaoxi told Xu Mang that this experiment lasted for a few days and repeated tests many times, and Xu Mang could only silently accept this few days.

Coming home from work,

Xu Mang just carried a bag of vegetables and put it in the refrigerator, but Yang Xiaoman came back with a stomach full of anger, and when he saw her appearance, he knew that he must have been bullied again, but he was also full of curiosity about it, who bullied her.

"Wife?"

"What's the situation?" Xu Mang asked curiously, "When I got home, I sat sullenly on the sofa, and I didn't watch TV... Are you being bullied?"

"I'm!"

"I ordered a piece of equipment last year, but today it was suddenly announced that it would not be sold to us. Yang Xiaoman pouted, his face was full of anger, and said: "This is a device worth 1.5 billion, mainly for Dad's company." ”

"Anyway, my mother, I'm completely torn off with them, and I'm going to raise the price of the American market. Yang Xiaoman said angrily: "It's really not good... I refuse all the needs of the United States, and I will not sell them to him, and whoever dares to sell them will terminate all contracts with him. ”

"Huh?"

"Why don't I know?" Xu Mang asked with a confused expression, "What kind of equipment is it?"

"The mask is aligned with the exposure machine..."Yang Xiaoman glanced at Xu Mang, and said seriously: "Husband... Are you going to build this kind of device? You can use photoresist materials first, so it shouldn't be a problem to align this mask with the exposure machine, right?"

"Uh..."

"No!" Xu Mang shook his head and said helplessly: "Materials and equipment are two different concepts, even if there are drawings of the mask alignment exposure machine, we can't make it... This kind of precision equipment requires professional manufacturing equipment, and we lack this kind of high-precision manufacturing equipment. ”

Xu Mang was also very helpless, before he was like solving the problem of the mask alignment exposure machine, but found that it couldn't be solved at all... The lack of sophisticated equipment to make a mask alignment exposure machine was beyond his competence.

"Ugh..."

"What should I do?"

"Damn the United States, it's blocking me from buying equipment. Yang Xiaoman said angrily: "I really want to wipe this damn country off the earth, as long as this world is without them, the world will be peaceful a long time ago." ”

This,

Xu Mang especially agrees with Xiao Man's point of view, and he also thinks that they should be leveled, but... Unlikely at the moment.

"Alright, alright. Xu Mang sat beside Xiao Man, silently hugged her into his arms, rubbed his handsome little face, and said helplessly: "Don't be angry... There are some things that we can't control at all, if we don't sell them, we won't sell them, what else can we do?"

"I was very unconvinced. ”

"It was negotiated a year ago, but now it says that if it is not sold, it will not be sold. Yang Xiaoman complained to Xu Mang: "Backtracking..."

"After all, people are on the same front, and we don't agree with their values. Xu Mang said helplessly: "Anyway, you have also mastered a lot of core technologies, and they are also annoyed... Now the situation in the world is not very stable, so be it ... More on that later. ”

Yang Xiaoman pouted and didn't speak, now it's quite chaotic... It's either a fire or a war, glancing at Xu Mang, who was holding him, and said in a squeaky voice: "Old lady, I'm very angry now, and I need you to give me a little vitality." ”

Words fall,

Silently closed his eyes, waiting for Xu Mang's next move.

Looking at her expectant appearance, Xu Mang understood that if she couldn't meet Xiao Man's request, it was very likely that her dog head would be blown up by her, and this woman was very unreasonable.

(*￣3(*^▽^*)

night

Quietly,

Xu Mang sat at the head of the bed, watched the news with the tablet, learned about international events, looked at it and felt that it was not interesting, opened the game and planned to have a tense and exciting Glory of Kings, but at this time, Xiaoman came back from taking a shower.

"Husband?"

"I've noticed that I've grown taller lately. Yang Xiaoman said: "I couldn't reach the shower before, but now I can reach it." ”

“...”

"You're in your twenties, your bone line has long been healed, and you can still grow a fart!" Xu Mang said angrily: "That's me quietly moving down a little, don't be full of doubts about your height, you are really short... Accept the facts. ”

Yang Xiaoman is so angry, I can't wait to kill this man, I have to expose it to my face, can't I save some face for my mother?

"Huh?"

"Why did you start cheating people again?" Yang Xiaoman saw Xu Mang playing a game, and said with a blank look: "At your level... Stop playing games, hurt others and yourself. ”

"Huh?"

"Xiao Man... Will you take me to fly?" Xu Mang said with a smile: "Take me to play two rankings." ”

ultimately

Under Xu Mang's good words, Yang Xiaoman reluctantly took Xu Mang to swim in the sea of victory, but he went in with confidence, crying and shouting out, there was no way... It's so vegetable, it's so dishful that you can't look at it directly.

"What are you doing?

"Let's fight! Old lady, I'll let you come to team fight! Did you hear that? Are you back in town?"

"Roll !!"

...

On this day,

Xu Mang returned to the research institute and re-came to the laboratory after a two-day absence, with a different feeling, looking at everyone's hard work, very gratifying... Silently, Xu Mang returned to his office, locked the office door, and then slept inside.

hasn't fallen asleep yet,

A hurried knock on the door woke Xu Mang, and he had no choice but to open the door and saw Song Xiaoxi standing at the door with the information.

"Something?"

"The experiment is done. Song Xiaoxi handed Xu Mang a stack of materials and said seriously: "Professor Xu, this is the data on the sample structure and electrical characterization of quantum anomalous Hall insulators and superconductors in the experiment. ”

"This is the data from the superconductor and the quantum-anomalous Hall insulator contact by means of superconducting nanoprobes. Song Xiaoxi said: "Professor Xu... In our experiments, we have demonstrated that the differential conductance of the nanoprobe at DC bias conforms to the Andreev reflection model, and the differential conductance at zero DC bias is nearly twice as strong as that at high bias. ”

"Your prediction is correct, and there is indeed a near-ideal contact between the superconductor and the quantum anomalous Hall insulator. Song Xiaoxi said with a look of adoration: "Professor Xu... What are we going to do next?"

"You go back to the office first. ”

"I'll let you know when the time comes. Xu Mang said indifferently.

"Hmm!"

Song Xiaoxi just walked to the door, turned around and said to Xu Mang: "Professor Xu... Can I take a leave of absence? I haven't met Vivi yet in the Demon Capital, and she doesn't even know I'm in the Demon Capital. ”

"Oh..."

After Song Xiaoxi left, Xu Mang checked Cao Cong's previous paper, and he found that semi-integer quantification and integer quantified conductance platforms coexist, but in the data provided by Song Xiaoxi, there is no integer quantized conductance platform, but the semi-integer quantized conductance platform not only appears in the specific magnetic field range predicted by the theory, but also appears in the entire Hall curve.

Maybe it's just an accident, but you can break through it and look for the conditions for it to happen, or maybe it's not an accident, but a theorem.

At this point,

Xu Mang wants more experimental results to test a theoretical model, but it should start the day after tomorrow.

"It seems..."

"Chiral Majorana fermions don't exist. Xu Mang frowned, carefully studying the data report, and he had a feeling that the truth of the matter would soon be revealed, and then there would be a big avalanche in the physics world.

"Hello?"

"Jiang Suo?"

"Can you send more than 30 samples?" Xu Mang said with a smile: "I need more sample data to explain a physical model, for now... The results of the first experiments are already difficult to explain with the physical models predicted by the chiral Majorana fermion theory. ”

"Of course, there may be chances, and I want to know thoroughly whether this is an accident or an inevitable result. Xu Mang said seriously: "There are many things to study here, and it is a good pair of anomalous Hall insulators and superconductors to explore." ”

"Good!"

"I'll arrange it right away. Jiang said seriously.

...

Afternoon

Yang Xiaoman, Zhou Weiwei, Song Xiaoxi and Lin Qiongcheng, the four of them were drinking afternoon tea together, chatting about beauty, cosmetics and other topics, but soon this topic involved Xu Mang, followed by a large-scale sycophant.

"Xiao Man!"

"I never thought that your husband would be Professor Xu Mang. Song Xiaoxi sighed with emotion: "Let me briefly talk about my experience in the past few days... It can be summed up in one word, and that's invincible! Maybe you don't think it's a big deal, but to me it's invincible. ”

"Without any experimental data, two prerequisites must be met for predicting the existence of chiral Majorana fermions based on theoretical models alone... This strength, I can only say invincible. Song Xiaoxi said with emotion: "Xiaoman... How can we find a man as good as Professor Xu Mang?"

Words fall,

Lin Qiongcheng also looked at Yang Xiaoman curiously, his eyes were full of longing.

In the face of the curiosity of the two, although they don't want to admit it, the fact is that they can chase him, that guy is passively beaten, all of them are on their own initiative, and the details of this must not be known to a third person.

"Rely on charm!" Yang Xiaoman said indifferently: "It was he who chased me, sticking to me all day long." ”
