I really don't want to lie down and win

Chapter 444 Kong Fei's Embarrassing Situation (1/3)

The next day,

As usual, Professor Li Aimin brought his own textbooks to teach the students. Xu Mang's appearance yesterday did not disrupt his routine, but he just felt that Xu Mang was a bit stubborn. He knew it was difficult, but he still had a headache. Iron is going to do it.

To put it nicely, it's called stubbornness, but to put it bluntly, it's a bit stupid, no...it's stupid!

The class is over soon,

Just as Professor Li Aimin was leaving, one of his favorite students, Kong Fei, found him. He needed Professor Li's help to guide him with a difficult problem.

As a leader in optics, Kong Fei’s research group cooperated with a research group at Nanyang Technological University to find a three-dimensional optical topological insulator. The goal of these two research groups is to extend the three-dimensional topological insulator from the fermion system to the boson system.

Therefore, the transmission efficiency of photons in the waveguide is greatly improved.

but,

Both sides have encountered problems. The research on three-dimensional optical topological insulators is still a blank in this field. The experimental research on optical topological insulators is limited to two-dimensional space. In many cases, a group of people are confused.

"Professor Li."

"Now we have encountered a very troublesome problem." Kong Fei said seriously: "We have encountered difficulties in the design of three-dimensional optical topological insulators, and we lack a new type of artificial heterotropic dielectric material."

"Material..."

"You'd better find someone from the Materials Department." Li Aimin said, "Maybe they can help you."

"..."

"Professor Li... two of our research team are from the Materials Department." Kong Fei said bitterly: "These two went to find their supervisors, but they didn't satisfy us. Material issues, this experimental design is also a big issue."

Kong Fei was desperate. This topic was chosen by herself. Nanyang Technological University was also invited by her to study together. As a result... just two weeks after the start, she encountered triple troubles in theory, materials, and experiments. This research project is currently under review. Come, it seems to be a false proposition.

"I'll take a look for you in the afternoon." Professor Li said, "But you have too much hope, and it's very likely that I don't know either."

"As long as you can come."

come back to the office,

Facing this topological insulator, Professor Li has done various researches. In fact, topological insulator is a research hotspot in the field of condensed matter physics. It is a very interesting material. The interior is insulating, but the surface can conduct electricity.

In the interior of topological insulators, the electronic band energy results are very similar to conventional insulators, the Fermi level lies between the conduction and valence bands, and the surface quantum states lie in the band gap of the bulk band structure, allowing conduction.

but...

Trying to extend the theory of topological insulators to optical systems, although it has been verified in two dimensions, a research team at Princeton University has realized a two-dimensional optical topological insulator through experiments, but this three-dimensional optical topological insulator...the physics world does not Not optimistic.

in the afternoon,

Professor Li Aimin came to Kong Fei's laboratory and saw her experimental process. The result made Professor Li helpless. This topic is currently in a theoretical state. There is no ready-made experimental equipment to help with measurement, and even the theory has problems. .

This cannot be blamed on Kong Fei and the others. After all, this is a brand new field. Starting from scratch... It is not easy to build a scientific fortress in the ruins. From the electronic system to the optical system, from two-dimensional to three-dimensional, the research objects There are many fundamental differences.

"It's over..." A certain student said pessimistically, "Professor Li...do we still have a chance to save him?"

Hearing the student's words, Professor Li gave a wry smile. Normally, the death penalty is pronounced, but...it's not to the point where research is impossible, and there may be opportunities in the future.

"actually..."

"You still have a chance." Professor Li said solemnly: "As long as the materials can be found, the remaining problems will be almost solved."

material,

Why not!

But I just couldn't find it, and even the material department was helpless.

"Have it!"

suddenly,

Kong Fei shouted excitedly. Just now, the shadow of a bitch appeared in her mind. There was a hint of a cheap smile on this person's face. It seemed that he gave it for nothing, but he often gave people unexpected surprises. .

His nickname is Pipixu, and his real name is Xu Mang... A professor of theoretical physics in the Department of Physics, he was still his primary school student half a year ago.

"Professor Xu!"

"We can ask Professor Xu for help, he may be able to solve our problem." Kong Fei shouted.

Xu Mang?

Professor Xu?

Right!

Hearing Kong Fei's words, everyone except Professor Li was extremely excited, but...Professor Li Aimin felt a little helpless.

"If you want to find Professor Xu, you may have to wait for a while." Li Aimin said seriously: "He is designing a brand new laser device."

"???"

"???"

"???"

what?

Professor Xu, who is engaged in theoretical physics, actually started to involve laser equipment?

The faces of those majoring in optics were full of confusion. It wasn't that they looked down on Professor Xu Mang, but...this is not in line with science. It's like a person who sings and dances and suddenly goes to the NBA to play basketball. How is it possible... .

Not to mention the NBA, it is estimated that even the school team will not be able to get in.

"Professor Li?"

"You...you're not joking, are you?" Kong Fei asked in surprise: "Professor Xu is really designing laser equipment? He... isn't he studying theoretical physics? Why is he suddenly studying optical equipment? Professor Xu can't think about it anymore?"

"This..."

"He uses laser equipment to study the probability of quantum mechanics to detect the probability of atoms in space." Li Aimin said, "In short, you temporarily gave up on the decision to find Xu Mang, and he really doesn't have time now."

After Li Aimin left,

The laboratory was extremely lively. What they discussed was not the problems they encountered, but the topic of Xu Mang's design of laser equipment.

"Sister?"

"You seem to have cooperated with Professor Xu before. Do you think Professor Xu has a high success rate in designing a new laser device?" A student asked curiously, "I'm studying materials, and I don't know your physics department. door frame."
