At this time, Liu Yun'er was slightly embarrassed, and asked Lin Fan to get close to others, probe the bottom of others, and briefly inspect his character, but this bastard turned out to be good... When you come up, you will make others shut up.

"Uh..."

"I..." Liu Yun'er drove the car, not knowing how to answer Lin Fan's behavior for a while, but soon she reacted and whispered, "Why are you so nervous?"

“...”

"Zhou Feng is also my colleague, I just care about my colleague. Song Yuxi said indifferently: "Now that your boyfriend is very autistic, it has dealt a big blow to his self-confidence and has an impact on his future research path." ”

Liu Yun'er sighed, and was about to open her mouth to remind Lin Fan when she heard that Zhou Feng had already spoken.

"Brother Lin Fan?"

"You must be in our field of optics, right?" Zhou Feng was very excited, and said seriously: "Some of your questions are completely some of the key problems encountered in my research project, and it is impossible for me to analyze so many problems through my words." ”

Lin Fan smiled and said silently: "I'm a... It's just a little-known person. ”

"No, no, no..."

"I trust my instincts. Zhou Feng said sincerely: "Since this is the case... We can dig a little deeper. ”

"In fact, our original intention is to realize the future photonic chips, and the realization of the future photonic chips is a huge challenge... It is probably that when the electromagnetic waves make a 'sharp turn', they will not scatter the phenomenon. Zhou Feng said seriously: "Topological insulators are the source of inspiration for this research. ”

Lin Fan nodded and said indifferently: "I remember that Princeton University proposed a thought experiment to extend the theory of topological insulators to optical systems, which was hugely controversial in the scientific research community at that time, until ten years ago... For the first time, a two-dimensional optical topological insulator was experimentally realized. ”

"I think..."

"Brother Zhou's inspiration probably came from here, right?" Lin Fan asked.

Zhou Feng didn't feel any surprise, and hurriedly said, "Yes... Therefore, I put forward the design theory of three-dimensional optical topological insulators, and tried to build a new experimental system. It will be the first attempt by the scientific research community to realize optical three-dimensional topological insulators by experiments. ”

At this point,

Liu Yun'er couldn't bear to interrupt the conversation between the two big men in the back row, this is an important conversation that has the potential to change the field of optics, if he interrupts this conversation and is known by his colleagues in the field of optics, how much he hates himself.

“...”

"Rain Creek... Or..."Liu Yun'er said bitterly, "Let the two of them talk first, right?"

"Hmm..."Song Yuxi sighed and said silently.

At this moment,

Zhou Feng took out a tablet from his bag, moved his body involuntarily to Lin Fan's side, pointed to a certain model on the tablet, and said, "Brother Lin Fan... You look at the model that was built by the computer, and this is the element structure of multiple open resonators that I mentioned earlier. ”

Lin Fan took a closer look, his expression wrinkled slightly, as if he had thought of something.

"This kind of structure..."Lin Fan pursed his lips, not knowing how to speak for a while.

"Brother Lin Fan, if you have anything to say, just say it directly!" Zhou Feng said seriously: "If you feel that something is wrong, just tell me directly." ”

"It's not..."

"I took a look at your model, a model of this structure... Does it have a topological energy gap because of this?" Lin Fan asked curiously: "I'll just ask casually, after all, I also know a little about optics." ”

Suddenly

Zhou Feng's jaw was about to drop.

Boy... Just by looking at it, he could see the magic of this structure.

Is he human?

"Brother Lin Fan..."

"I finally know what it means to have mountains outside the mountains and people outside the people. Zhou Feng sighed and said silently: "Indeed... In our preliminary theoretical design, and through various calculations... It is concluded that the material has a three-dimensional energy gap. ”

"But..."Zhou Feng said with a wry smile, "We don't know how to observe." ”

In fact

Lin Fan didn't know how to observe, he mainly wanted to know how Zhou Feng thought about this problem and what solution he had to solve this problem, so as to satisfy his curiosity, and as a result... The other party doesn't know either.

"Oh..."

"I don't know. Lin Fan shook his head and said helplessly: "This problem is very difficult, first of all, it must be theoretically serious, and this part involves the topological concept of condensed matter physics, and at the same time, the existence form of the Dirac cone must be considered. ”

"Here..."

"It also involves solid state physics and physical quantity measurements, anyway... It's complicated. Lin Fan took out his mobile phone again and said casually.

Zhou Feng is used to it, the shock given by the young man next to him, don't look at his appearance, but as soon as he opens his mouth, he knows that this is the existence of a top boss.

"Brother Lin Fan. ”

"Actually... [567 Chinese ]."

Zhou Feng paused, hesitated for a long time, and then said: "Actually, we thought of two plans, but there was a dispute in the internal group, and no one could convince anyone. ”

Words fall,

Zhou Feng cautiously asked, "Brother Lin Fan... Interested in checking it out?"

"Okay!"

Lin Fan nodded hurriedly, but he was still reserved and asked, "Is it in line with the rules?"

"It's fine!"

"I'll have the final say!" Zhou Feng said with a smile.

Followed by

The two big men got together, each put forward some opinions on the two plans in front of them, and at the same time fiercely refuted each other's views, and from time to time they would provide each other with new ideas.

"Hmm... I think there's a problem here, you see... According to the dispersion relation..."

"Really? I'll see... Yes, yes, there is a problem here, and if that's the case, then... Is the electron mobility then recalculated?"

"That's right!"

Unconsciously,

Liu Yun'er drove the car to a service area on the expressway, glanced at the rearview mirror in the car, and the two big men were still sitting together, one holding a tablet, and the other holding a notepad and pen, not knowing what they were doing.

“...”

"Rain Creek?"

"Go down and breathe?" Liu Yun'er asked, "Just buy something." ”

"Hmm..."Song Yuxi nodded.

moment

The two got out of the car, then came to the beverage shop in the service area, each ordered a cup of milk tea, and sat in the passenger rest area.

"I feel..."Liu Yun'er frowned, looked at the good sister in front of her, and said silently: "I think the two of us are redundant, you look at the two people in the back row, how happy they chatted, as if they had found a long-lost brother." ”

“...”

"I'm also wondering. Song Yuxi smiled bitterly: "Zhou Feng is in the research institute, and he belongs to the taciturn category... But I was able to talk to Lin Fan. ”

Liu Yun'er pondered for a moment and said seriously: "Being able to talk to that guy shows a problem... Zhou Feng's IQ is very high, and his character is quite good, otherwise Lin Fan would not have taken care of others. ”

"Huh?"

"Actually, I found that you care about Zhou Feng. Liu Yun'er said.

“...”

"Didn't I say that?" Song Yuxi said helplessly: "I care about my colleagues." ”

Liu Yun'er glanced at each other and said angrily: "Yuxi... Now that I'm a woman with experience in love, I can't see what it means to care about my colleagues?"

"Cut..."

"You've only been in love with Lin Fan for a few days, and you've started to be a person from the past. Song Yuxi said angrily.

"How?"

"Even if you are in love for a day, you are much stronger!" Liu Yun'er said.

These words almost made Song Yuxi angry, and said angrily: "Every day..."

"Actually, you can be so good. Liu Yun'er said.

“...”

"Actually..."

Song Yuxi sighed and said silently: "Zhou Feng is very good, he is very good in all aspects, and he is quite honest, that is... Married, then divorced. ”

"Why did you leave?" asked Liu Yun'er.

"The working relationship... Zhou Feng and his ex-wife are too busy and have been separated for a long time, just... And he left. Song Yuxi sighed: "Actually, it's nothing to be married, I'm afraid... I have always been obsessed with my ex-wife. ”

Oh!

It turned out to be worried about this!

Liu Yun'er nodded silently and pondered for a moment... said: "What did his ex-wife do?"

"I'm not from the census, so how can I know so clearly. Song Yuxi said: "Let's take a step and see a step." ”

moment

After buying two drinks for Lin Fan and Zhou Feng and returning to the car, they found that the two guys in the back row were still studying how to observe the surface state in the form of a two-dimensional Dirac cone.

“...”

"Two?" Liu Yun'er asked cautiously, "Are you thirsty?"

"Is Brother Zhou thirsty?" Lin Fan asked.

"Uh..."

"I'm thirsty. Zhou Feng nodded.

As soon as the voice fell,

Lin Fan said to Liu Yun'er: "Yun'er, buy me and Brother Zhou two bottles of water." ”

Liu Yun'er was about to explode, but she still gave Lin Fan enough face in front of outsiders, and silently handed him two bottles of drinks.

subsequently

The two took a few sips and began to study the surface state of the two-dimensional Dirac cone again.

didn't bother with the two guys in the back row,

Liu Yun'er started the car and started the rest of the journey.

Long

Finally arrived at the hot spring inn.

Song Yuxi had already received Liu Yun'er's WeChat message before she got into the car, and there was no accident about it, at this time she unbuckled her seat belt and was about to get out of the car, and then glanced behind her.

"Ahem!"

"Zhou Feng... It's here. Song Yuxi said indifferently.

meanwhile

Liu Yun'er also spoke: "Lin Fan... It's time to get off!"

Lin Fan and Zhou Feng were stunned for a moment, looking at their respective women blankly, each other's eyes revealed a little dazed, their expressions were so overwhelmed, and even a little unsatisfied.

At this moment,

The two men suddenly realized that if this trip was made without a woman... How perfect it is!

These two women,

It's completely redundant!
