I really don't want to lie down and win

"Ugh?"

"Xiaoman...you take me to fly?" Xu Mang said with a smile, "Take me to play two rankings."

finally,

Under Xu Mang's good words, Yang Xiaoman reluctantly took Xu Mang to swim in the ocean of victory, but he went in full of confidence, and came out crying. The point of looking straight ahead.

"What are you doing? Checking WeChat steps?"

"Come to the team battle! My old lady, I let you come to the team battle! Did you hear that? You...you returned to the city?"

"roll!!!"

...

this day,

Xu Mang returned to the research institute. After two days away, he returned to the laboratory. He felt a different feeling. Seeing everyone working hard, he felt very gratified... Xu Mang silently returned to his office, and took the Lock the door and sleep in it.

Before Xu Mang fell asleep,

A sudden knock on the door woke Xu Mang up, and he opened the door helplessly, only to see Song Xiaoxi standing at the door with the documents.

"Is something wrong?"

"The experiment is complete." Song Xiaoxi handed Xu Mang a stack of materials, and said seriously, "Professor Xu, this is the data on the structure and electrical characterization of the quantum anomalous Hall insulator and superconductor heterojunction sample in the experiment."

"This is the data used to characterize the contact between a superconductor and a quantum anomalous Hall insulator through superconducting nanoprobes." Song Xiaoxi said: "Professor Xu... In our experiments, we have proved that the nanoprobes under DC bias The differential conductance conforms to the Andreev reflection model, and the differential conductance at zero DC bias produces nearly twice the enhancement effect compared to the differential conductance at high bias."

"Your prediction is not wrong. A nearly ideal contact has indeed been established between the superconductor and the quantum anomalous Hall insulator." Song Xiaoxi said with admiration: "Professor Xu... what should we do next?"

"You go back to the office first."

"I will notify you when the time comes." Xu Mang said calmly.

"Ok!"

Just as Song Xiaoxi walked to the door, she turned to Xu Mang and said, "Professor Xu...can I ask for a leave of absence? I haven't met Weiwei in Shanghai yet, and she doesn't even know I'm in Shanghai."

"Oh..."

After Song Xiaoxi left, Xu Mang checked Cao Cong's previous theory. He found that half-integer quantization and integer quantization conductance platforms coexisted. However, in the data provided by Song Xiaoxi, there was no integer quantization conductance platform, but half-integer quantization The 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.

Perhaps this is just an accident, but we can make a breakthrough from it and find the conditions for the accident to happen. It is also possible that this is not an accident, but a theorem.

at this time,

What Xu Mang wanted was more experimental results to verify a theoretical model, but it should start the day after tomorrow.

"It seems..."

"Chiral Majorana fermions don't exist." Xu Mang frowned, studying the data report carefully. He had a feeling that the truth of the matter would be announced soon, and that something would happen in the physics world. A big avalanche.

"Hey?"

"Jiang Suo?"

"Can you send over thirty more samples?" Xu Mang said with a smile: "I need more sample data to explain a physical model. At present... the results of the first experiment are difficult to analyze with chirality." The physical model predicted by Majorana's fermion theory is explained."

"Of course there may be chance, and I want to know thoroughly whether it's a coincidence or an inevitable result." Xu Mang said seriously: "There are a lot of things to study here, and it's a good exploration of anomalous Hall insulators and superconductors. "

"it is good!"

"I'll make arrangements right away." Jiang Suo said seriously.

...

in the afternoon,

Yang Xiaoman, Zhou Weiwei, Song Xiaoxi, and Lin Qiongcheng were drinking afternoon tea together, chatting about beauty, cosmetics and other topics, but soon this topic involved Xu Mang, and then there was a large-scale flattery .

"Xiaoman!"

"I never thought that your husband is actually Professor Xu Mang." Song Xiaoxi said with emotion, "Let me briefly talk about my experience in the past few days... I can sum it up in one word, that is invincible! Maybe You don’t think it’s a big deal, but to me it’s invincible.”

"Without any experimental data, it is only predicted based on the theoretical model that there must be two prerequisites for the existence of chiral Majorana fermions... I can only say that this strength is invincible." Song Xiaoxi said with emotion: "Xiaoman... How on earth can I find a man as good as Professor Xu Mang?"

words fell,

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

Facing the curiosity of the two of them, even though he didn't want to admit it, the fact is that he was chased by him, that guy was beaten passively, and all of them took the initiative, and the details inside must not be known to a third person.

"Rely on charm!" Yang Xiaoman said indifferently: "He was the one who chased me, clinging to me all day long."

......

Chapter 798 Xu Mang's Answer (2/3)

The second batch of samples was successfully sent to the Xu Yang Research Institute, waiting for Xu Mang to release the next announcement, but at this time he has not announced it yet, and needs to further complete the theory. When it will be completed is unknown.

this day,

Xu Mang was sitting in his office. He was still at a loss as to what to do next. Although experiments were needed to tell the result, according to Xu Mang's previous theoretical calculations, the quantized conductance was greater than [-]% when the external magnetic field exceeded It is a fact that the critical conditions of superconductors still exist, which cannot be modified.

He believed that even if he tested samples from all over the world, he still came to the same conclusion. Regarding this... Before the test, Xu Mang gave a preliminary explanation based on this physical model. The quantum anomalous insulators on both sides are simply electrically connected, so the so-called short circuit phenomenon occurs.

And this circuit allowed him to observe the half-integer quantized conductance platform, so Xu Mang boldly speculated that the half-integer quantum platform was caused by a short circuit, not chiral Majorana fermions.

For this,

Xu Mang shared a theoretical idea with Jiang Suo of the Beijing Institute of Condensed Matter Physics, but...Jiang Suo was speechless.

"Xu Mang!"

"You... your calculation is terrible!" Jiang Suo said seriously: "You said that in Cao Cong's research report, the discovery of chiral Majorana fermions was entirely caused by a short circuit. ...If this is announced, I am afraid that the other party will be ruined."

"Okay!"

"It's just to ruin his reputation." Xu Mang said with a smile: "Show him, is Jiang Suo familiar with Cao Cong? Why does he hate us so much? Everyone has the same gene in their blood. Once you become an American, you start to behave badly."

"..."

"I'm not very familiar with him, but since the change of nationality, I have always hated us." Jiang Suo said: "I don't know exactly why, but there are not many such people, it's just an accidental phenomenon."

"Ok!"

Xu Mang nodded. He also stayed abroad for a while before, but no matter how full the moon is abroad, he still has to go back to the place where he originally lived. There is no way... This is a strong sense of belonging to his motherland I feel that there is no better place in the world than Huaguo.
