"Although we have experimented many times and obtained the same results many times, we were relieved when the news of the successful replication of the experiment came from the Columbia research team."

Recalling what happened after the success of the experiment, Cao Yuan couldn't help but smile.

Wu Bin nodded: "It's natural to be nervous, after all, since graphene was discovered, this field has never been so exciting." ”

Cao Yuan: "Actually, because the repetition process is more difficult than expected, and the news from other experimental teams is slower than we thought, but immediately after Professor Kerui's team successfully replicated this success, three other teams also confirmed its reproducibility. ”

After listening to Cao Yuan's words, Wu Bin suddenly remembered something and said, "In addition to verifying the results, why don't you start studying the results of your experiments directly?" I remember seeing quite a few articles on arXiv trying to explain this phenomenon. ”

"That's right." Cao Yuan nodded, "Many teams are using their methods to adjust the interlayer structure of other two-dimensional materials, looking for other forms of electronic interaction. ”

Wu Bin: "To put it simply, everyone is trying to stack their favorite materials and rotate them, right? ”

Cao Yuan raised his glasses after listening: "Yes, but more information is needed now to determine whether the mechanism that induces bilayer graphene to achieve superconductivity is the same mechanism behind high-temperature superconductors, but so far, in addition to the recognition that this system is worth studying, those theoretical physicists have not reached any consensus at all." ”

After speaking, Cao Yuan glanced at Wu Bin and asked, "Did you find anything?" ”

"Me?" Wu Bin thought for a while and said: "How to say, I think that the basis for superconductivity in rotating bilayer graphene is similar to the traditional iron-based superconductivity. ”

Cao Yuan glanced at Wu Bin in surprise, and then said with a smile: "Hahaha, or the junior has a vision, in fact, we have not emphasized that we have made the so-called 'high-temperature superconductivity', but the media likes to blow, after all, the transformation of 1K is not high, and the similarity you mentioned is the shining point in this experiment." ”

After speaking, Cao Yuan suddenly stood up and walked to the blackboard in the conference room, picked up a piece of chalk and began to write while saying: "In fact, when studying high-temperature superconductivity in copper oxides, we found that under the condition of improving the experimental conditions and equipment, a small amount of mixed Mott insulator phase will undergo superconducting phase transformation, and similar phenomena have been observed in several samples. ”

Looking at the values written by Cao Yuan on the blackboard, Wu Bin couldn't help but fall into thought, and his five fingers kept playing rhythms on the table.

When Cao Yuan finally put down the chalk, Wu Bin also walked up to the blackboard and picked up a piece of chalk and said: "Although the superconducting transition temperature is about 1K, it is not high, but because of the extremely low concentration of particles in graphene under the aforementioned conditions, this transition temperature is actually very high......

At this time, at the door of the conference room, Qin Simeng, who secretly listened to the two of them through a crack in the door, silently closed the door.

"What are they talking about?" Li Yan, who was playing with his mobile phone in the back, raised his head and asked.

"I don't understand...... Qin Simeng had an expression on his face who I am and where I am.

"Hahaha." Li Yan snickered twice: "Anyway, I don't listen, it's not worth the blow of two monsters." ”

Qin Simeng let out a sigh: "I'm thinking about whether these two people will solve some world problems by chatting, and I'm also a witness." ”

"Forget it~" Li Yan stuffed his mobile phone back into his pants pocket: "It's the right way for mortals like us to go to class." ”

"Yes." Qin Simeng sighed and walked out with Li Yan.

When he came to the hall, a member of the student union immediately came over and greeted Qin Simeng when he saw him coming: "Hey, what a coincidence, you also came to the student union?" ”

"Well, look at a great god." Qin Simeng smiled and nodded.

"Oh, I just heard that Senior Cao Yuan is back, right, I'm going to go to the film later." After speaking, the boy suddenly shouted: "By the way, I went to see you two days ago, and I played very well." ”

"Thank you." Qin Simeng nodded politely.

"One more thing." The boy said and took out two tickets: "I bought two tickets for Turando the day before yesterday, but my friend who said that I would go with me released the pigeons, I know that you are also very interested in opera, why don't you go together?" This ticket is very difficult to buy, and it is a pity to waste it. ”

Although the boy's tone has been as casual as possible when he speaks, his voice is still mixed with some nervousness.

After hearing this, Qin Simeng replied with a smile: "I'm sorry, I have a bit of homework to make up in the past two weeks, I'm afraid I won't be able to spare this time." ”

"That's it......" The boy's expression was a little disappointed, but he immediately adjusted and said, "Okay, I'll ask someone else." ”

"Okay, thank you for the invitation." After Qin Simeng finished speaking, he turned around and walked towards the door.

Looking at Qin Simeng's departing back, the boy sighed, stuffed the two tickets back into his pocket and left.

'Tsk...... It's tragic. Li Yan, who was standing at the door, couldn't help but shake his head and saw away the warrior who dared to act.

After all, there have been too many seniors who have been politely rejected by Senior Sister Qin before, and those who still dare to act are all worthy of the word "warrior".

"Do you have any other arrangements for Senior Cao Yuan in the evening?" At this time, Qin Simeng walked up to Li Yan and asked.

Li Yan shook his head: "There shouldn't be one today, it is estimated that the school can also imagine that there should be a lot of chats between these two when they meet, but there will be a dinner tomorrow, but Senior Cao Yuan and his original teachers will eat." ”

"Uh-oh." Qin Simeng nodded, "Then I'll go to class first." ”

"Okay, goodbye, senior sister." Li Yan waved at her.

……

In the evening, Qin Simeng returned to the conference room where Wu Bin and Cao Yuan were and knocked on the door.

"Huh, senior sister? Can I help you? Wu Bin, who came to open the door, said with some surprise.

Qin Simeng smiled and brought the bag in his hand to Wu Bin: "I think you guys are talking so seriously, you will probably miss the meal time, so I helped you get two meals." ”

Wu Bin, who smelled the aroma of rice, did feel a little empty in his stomach, so he said happily: "Thank you, senior sister, for being so thoughtful." Then he turned around and asked Cao Yuan, "Senior Cao Yuan, do you want to eat some?" ”

"I'm a little hungry." Cao Yuan nodded and walked over, glanced at the lunch box in Qin Simeng's hand and said, "I'm in trouble." ”

"It's just a matter of convenience." Qin Simeng said as he took out the food in the bag and put it on the table.

When she was swinging, Qin Simeng turned her head and glanced at the blackboard, and found that it was full of formulas that made her confused.

'I always feel like he's the only one who went to a real university......
