I really don't want to lie down and win

Professor Li hurriedly said, "Xu Mang just happens that you have time, so please guide Kong Fei's team on the difficult problems."

"what?"

"Professor Li, you can't solve it either?" Xu Mang asked curiously.

Professor Li shook his head and said seriously: "It seems that this is an optical problem, but it is actually a problem of your theoretical physics and condensed matter physics. The transformation from two-dimensional to three-dimensional requires the support of a physical theory. Topological insulators themselves belong to condensed matter."

"Oh?"

"So high-end?" Professor Li's explanation aroused Xu Mang's curiosity. He turned to look at Kong Fei and asked, "What problems did you encounter?"

moment,

Xu Mang had an extra research project plan in his hand, and he briefly read it. Xu Mang couldn't help but praise a few people. This is indeed a very good research direction. If it succeeds, it will have huge implications for the development of future photonic chips. effect.

In many devices, the electromagnetic wave must go around the bend, and once the turn is large, the electromagnetic wave will scatter and affect the transmission efficiency, but the turn is small, which is not conducive to saving space. No scattering occurs either.

at the same time,

Kong Fei and the others were very nervous. After all, Xu Mang was the last hope. If even Xu Mang couldn't solve it, this project could only end here.

no one dared to speak,

For fear of affecting Xu Mang's thinking.

"This..." Xu Mang started, but stopped abruptly.

And this sudden opening almost scared Kong Fei and the others into fainting.

how?

Is there a problem?

Wrong way of thinking?

"this..."

"Yes!" Xu Mang said with a smile, "Not bad...the idea is very good, and if it succeeds, it may have a huge enlightenment effect on future photonic chips."

What the hell!

Professor Xu is too bad!

Take a big breath on purpose.

"Professor Xu!"

"Can you finish it all at once when you talk next time?" A student said helplessly: "You almost scared us to death. At first I thought our research project was over and it wouldn't work at all."

"hey-hey..."

"Just to tease you." Xu Mang said with a smile: "This research project of yours has some high-end... many of them belong to brand-new theoretical systems, such as the transformation from two-dimensional to three-dimensional. First, the design of three-dimensional optical topological insulators should be proposed. theory, but you don't!"

"There is no experimental system... I don't know what your first step is to study topological insulators, or to study scattering..." Xu Mang said seriously: "And...you have not grasped the point, three-dimensional The key features of optical topological insulators...you have not summarized."

"..."

"..."

"..."

Kong Fei wanted to say something, but in the end she held back. This matter needs to be resolved in private.

"Then what..."

"What problems do you want me to solve?" Xu Mang asked curiously, "It seems that there are many problems..."

For a time,

Kong Fei didn't know what to do anymore. According to what Xu Mang said, there were indeed too many problems to speak, and almost every one of them needed to be solved.

"Professor Xu..."

"Why don't you help us find a suitable material." A student said sincerely: "All our problems come from this place."

Xu Mang read their plan over and over again. Indeed...according to this experiment plan, the problem lies in the materials, but lacking a perfect system, even if you get the right materials, you will encounter a lot of other problems in the future. question.

Xu Mang shook his head, and said seriously: "Your experimental system is not good, even if you know the materials, you will encounter a lot of trouble."

For a time,

Kong Fei's team fell into an embarrassing situation at a loss, but Kong Fei was a little embarrassed.

"but..."

"It just so happens that I'm free for a while, so I can help you guide me." Xu Mang said with a smile.

Hearing Xu Mang's words,

Several people regained hope. As long as Professor Xu is on hand to guide them, many problems will not be problems at all.

after that,

Professor Li left with Xu Mang's plan. He wanted to help Xu Mang complete this special laser crystal, while Xu Mang himself stayed in the optical laboratory, watched the members of Kong Fei's team, and revised the plan as much as possible. Complete the system for this experiment.

With Xu Mang's assistance, the group quickly completed the relevant progress, but the problem was not resolved, and several people still faced endless problems.

quickly,

In-between breaks. .

Kong Fei found Xu Mang alone, met with old friends in private, and Kong Fei also called Xu Mang by his full name without politeness.

"Xu Mang!"

"Tell me the truth." Kong Fei asked seriously, "Is our difficulty very high?"

"..."

"It's not bad." Xu Mang said, "It's not high, it's not low. The main reason is that there is a problem with the structure of your team. There is not a single student majoring in theoretical physics or condensed matter physics."

Kong Fei hastily defended: "Actually, we are cooperating with Nanyang Technological University. Some aspects are not studied because they are responsible for those areas, such as this theoretical framework, and what you said about the properties of topological insulators."

Xu Mang froze for a moment, Nanyang Technological University?

Before Xu Mang could speak, Kong Fei sighed and said, "The research team we are cooperating with protects their materials very well, for fear that we will plagiarize them, but they keep urging me to submit our materials. .”

"Now..."
