Scholar’s Starry Sea

"Although we experimented many times and got the same results many times, when the Columbia University research team heard the news that the experiment was repeated successfully, it was relieved."

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

Wu Bin nodded: "It is natural to be nervous. After all, since the discovery of graphene, this field has never been so exciting."

Cao Yuan: "It is actually Because the process of repetition was more difficult than expected, and the time for news from other experimental teams was slower than we thought. However, after the success of Professor Corey’s team was successfully replicated, three other teams also confirmed its reproducibility. Sex."

After listening to Cao Yuan’s words, Wu Bin suddenly remembered something and said: "In addition to verifying the results, there are many who directly started to study the results of your experiments? I remember that time. I have seen quite a few articles trying to explain this phenomenon on arXiv."

"Yes." Cao Yuan nodded, "Many teams are using their methods to adjust the layers of other two-dimensional materials. Structure, looking for other forms of electronic interaction."

Wu Bin: "Simply put, everyone is trying to stack their favorite materials for rotation, right?"

Cao Yuan lifted his glasses after listening: "Yes, but more information is needed now to determine whether the mechanism that induces double-layer graphene to achieve superconductivity is the same mechanism behind the high-temperature superconductor. Unfortunately, so far In addition to the recognition that this system is worth studying, those theoretical Physics scientists have not reached any consensus at all."

After that, Cao Yuan glanced at Wu Bin and asked: "Do you have any findings? "

"Me?" Wu Bin thought for a while and said: "How to put it, I think the basic principle of superconductivity in rotating double-layer graphene is similar to traditional iron-based superconductivity. I have read this information recently, but there is still no progress."

Cao Yuan looked at Wu Bin in surprise, and then said with a smile: "Hahaha, or Junior Brother has a vision. In fact, we have never emphasized that we have made the so-called “high temperature superconductivity”, but the media likes to blow it up. After all, the 1K transition is not high. The similarity you mentioned is the shining point in this experiment. "

After talking, Cao Yuan suddenly stood up and walked to the blackboard in the Conference Hall. He picked up a piece of chalk and began to write as he said: "In fact, when studying high-temperature superconductivity in copper oxide We found that a small amount of mixed Mott insulator phase will undergo a superconducting phase transition when the experimental conditions and equipment are improved, and similar phenomena have been observed in several samples."

Looking at the numerical value written by Cao Yuan on the blackboard, Wu Bin couldn't help thinking. Five fingers kept tapping the rhythm on the table.

When Cao Yuan finally put down the chalk, Wu Bin went to the blackboard and picked up a piece of chalk and said, “Although the superconducting transition temperature is about 1K, it’s not too high, but because the graphene is in the aforementioned Under the conditions, the flux concentration is extremely low, so the transition temperature is actually very high..."

At this time, at the door of the Conference Hall, Qin Si secretly listened to the two people talking through a crack in the door. Meng closed the door silently.

"What are they talking about?" asked Li Yan, who was playing on the phone behind him, lifts the head.

"I don't understand..." Qin Simeng gave an expression of who I am and where I am.

"hahaha." Li Yan snickered twice: "Anyway, I don't listen. It's not worth getting hit by two monsters."

Qin Simeng let out a sigh of relief: "I'm thinking about whether these two people will solve some world problems while chatting. I'm also a witness."

"Forget it~" Li Yan plugged his phone back Pants pocket: "It's the right way for mortals like us to go to class."

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

When we came to the lobby, a member of the Student Union immediately came over and said when she saw Qin Simeng approaching oncoming: "Hey, it's such a coincidence, what will happen if you come to the students too?"

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

"Oh, I just heard that it is Cao Yuan Senior who is back, right? I'm going to go to the mask later." After speaking, the boy suddenly shouted: "Yes, before I went to watch your debate contest in two days. You played very well."

"Thank you." Qin Simeng politely nodded.

"One more thing." The boy said and took out two tickets: "I bought two Turandot tickets the day before yesterday, but the friend who said it was good to go together put the pigeons off. You are also very interested in opera. Would you like to go together? This ticket is very difficult to buy, and it’s a pity that it’s wasted."

Although the boys speak as casually as possible, the voice is still Mixed with some tension.

Qin Simeng smiled and replied after hearing this: "Sorry, I have to make up a lot of schoolwork in these two weeks, I am afraid I can't spare this time."

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

"Okay, thank you for your invitation." Qin Simeng finished speaking. Turned and moved towards the door and walked.

Looking at the back of Qin Simeng's departure, the boy sighed, tucked the two tickets back into his pocket and left.

'Hey...tragic. Standing at the door, Li Yan couldn't help shaking his head and watched away the warrior who dared to act.

After all, there have been too many seniors who were rejected by Qin’s senior sister Wan before, and those who dare to act up to now are all regarded as “warriors”.

"Are there any plans for Cao Yuan Senior at night?" Qin Simeng walked to Li Yan and asked.

Li Yan shook his head: "It shouldn't be there today. I guess the school can imagine that there should be a lot of conversations between the two. There will be a dinner tomorrow, but it's Cao Yuan Senior and him. A few teachers of the school have dinner."

"Oh oh." Qin Simeng nodded, "Then I will go to class first."

"Okay, Senior Sister, goodbye." Li Yan moved towards She waved her hand.

……

In the evening, Qin Simeng returned to the Conference Hall where Wu Bin and Cao Yuan were located and knocked on the door.

"Hey, Senior Sister? What's the matter?" Wu Bin, who came to open the door, said unexpectedly.

Qin Simeng smiled and carried the bag in his hand to Wu Bin: "I think you talk so seriously that you will probably miss the meal time, so I helped you two meals."

Wu Bin, who smelled the scent of rice, did feel a little empty in his stomach, and said happily, "Thank you Senior Sister for being so thoughtful." Then he turned around and asked Cao Yuan, "Cao Yuan Senior, Do you want to eat?"

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

"It's just a matter of convenience." Qin Simeng said, taking out the food in the bag and putting it on the table.

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

'I always feel that he is the only one who went to a real university...'
