I really don't want to lie down and win

More importantly, there is no complexity such as magnetic domains brought by magnetic materials, and the equipment can be directly used for experimental observation, which is convenient for obtaining the most direct evidence.

This...

This is the result of three hours? !

Xu Mang redefines the concept of three hours.

"Xu Mang?"

"Seriously...how on earth did you do it?" Fan Zhilong asked in disbelief: "What did you do back in your apartment? Fortunately, I received higher education, and then I thought you were God."

"Ha ha..."

"You're right. I'm indeed God, but I'm trying to understand God's thinking from a scientific perspective." Xu Mang said with a smile on his face, "Unsurprisingly, the TaAs crystal is a Weyl semimetal. More than 80 years of prophecy is about to be broken."

"In my calculations... the lattice constants of TaAs crystals are a3.44, c11.64, and it has a body-centered tetragonal structure, which belongs to a special space point group. There are 12 Weyl fermions with opposite chirality in the lattice momentum space .”

"There are open Fermi arcs on the surface, and there are pairs of Weyl cones with linear cross-cone band structures inside." Xu Mang said seriously: "These typical electronic structures can be observed, and I directly from the database."

Fan Zhilong didn't speak, he kept looking at these contents, and the excitement in his heart was unparalleled. If...if all this is true, then a secret of more than 80 years will really be broken, and this person will be from Professor of Physics Department of Fuda University.

but...

How to prepare such high-quality TaAs crystals?

"Xu Mang?"

"what?"

"Will you make this high-quality TaAs crystal?"

"No way!"

suddenly,

The laboratory was silent, and the two looked at each other, seeing the embarrassment in each other's eyes.

This...

After discussing so much and speaking clearly and logically, neither of them knew how to prepare this material. This means that the previous theories are all for nothing. No matter how correct the theory is, no matter how accurate the calculation is, it is all ridiculous without real objects to do research on.

"Hey?"

"Director Liu?" Xu Mang asked cautiously, "Guess who I am? There is no reward for guessing right."

"..."

This kind of speech is so cheap that you can know it with your toes. Who else can it be if it's not Xu Mang?

"I have a caller ID!" Liu Guofang, director of the Department of Materials, asked angrily, "What can I do for you? From your tone... it seems that you have encountered some trouble."

"hey-hey..."

"I just want to ask if our material department is capable of producing TaAs crystals?" Xu Mang asked in a low voice, "A high-quality TaAs crystal."

"TaAs crystal?"

"This seems to be something related to condensed matter?" Liu Guofang said seriously: "But we should be able to prepare it. By the way, what do you suddenly need this material for?"

"Do not ask!"

"Ask is changing the world." Xu Mang said with a smile, "That's fine... as long as it can be prepared, I'll come to your office later, let's discuss and prepare high-quality TaAs crystals as soon as possible."

hang up,

Xu Mang glanced at Fan Zhilong: "It can be prepared. I'll go to Director Liu's office of the Materials Department to finish the matter. Then, I will use STM equipment to measure the surface electronic state with high precision, and call it a day!"

"Tomorrow."

"See for yourself what time it is." Fan Zhilong reminded.

"Oh?"

"Damn it...I'm going to go shopping, or the tigress at home will go crazy." Xu Mang put his manuscript in his bag and asked Fan Zhilong, "Professor Fan...you Say I am a great scientist, why am I so humiliated at home?"

"..."

"It was Yang Xiaoman who asked you to marry." Fan Zhilong said helplessly, "You have to pay a price for what kind of woman you marry."

cost!

As expected, Professor Fan, who has been in the scientific research world for so long, hit the nail on the head... directly saw the root of the problem.

Xiaoman is very capricious,

but...

Xu Mang sighed, and said with a look of unrequited love, "I'm not afraid of making fun of you when I say it, so I'm fine with it."

words fell,

leave in a hurry.

The next day,

Xu Mang arrived at the Department of Materials Building early, stood at the door of Director Liu for a while, glanced at the fruit basket in his hand, thought about it carefully, and put it at the door, then pushed the door open and saw Director Liu in the office.

"Director Liu?"

"Busy?" Xu Mang put on his signature smile, walked up with a mean face, and stood opposite Liu Guofang.

"..."

Liu Guofang sighed, and said helplessly, "Xu Mang...Your status is different now, can you show a little seriousness as you should? Great scientist Xu?"

"It can't be changed."

"The country is easy to change and the nature is hard to change. You can't change it... unless you reincarnate again." Xu Mang smiled and said, "Then what... can we talk about work first, and then talk about personality?" question?"

"It's rare for you to get straight to the point for the first time." Liu Guofang asked, "Do you have any relevant information?"

"Have!"

"Look over it." Xu Mang took out a stack of manuscript paper from his bag and handed it to Director Liu Guofang.

After receiving the manuscript, Liu Guofang glanced at it. After a few minutes, she raised her head in surprise and asked seriously, "You said that the TaAs crystal is the Weyl semimetal material predicted more than 80 years ago?"

"Correct!"
