Start as a top student and move towards the stars and the sea

Even though Ning Chen has published more than ten papers in major academic journals, Ning Chen still keeps his attitude very low and does not think that he is so outstanding now.

In this world, too many geniuses have been born. They don't have any learning system, but they can still make all kinds of incredible research results.

Ning Chen thinks that he is not a very talented person, so Ning Chen must keep working hard at all times so as not to waste the benefits brought by the system to him.

In the evening, as the time agreed with Song Xiyun approached, Ning Chen changed into sportswear, put on the running shoes given to him by Song Xiyun, and came to the playground.

Song Xiyun also showed up on time. Tonight, Song Xiyun wore a ponytail and a light blue sportswear, looking very energetic.

Looking down Song Xiyun's slender legs, Ning Chen found that the running shoes Song Xiyun was wearing looked familiar.

This is also a pair of black running shoes. At first glance, they look very similar to the black running shoes Ning Chen wears.

But after Ning Chen observed carefully, he discovered that this was not just a matter of images.

And they are exactly the same!

Song Xiyun noticed that Ning Chen found out about her running shoes, and said a little shyly:

"That store has to buy the same type of running shoes to buy one get one free, so I don't have a choice."

Ning Chen quickly reacted and said calmly:

"It doesn't matter. We have different shoe sizes. We won't get confused even if we put them together."

Song Xiyun was helpless by Ning Chen's surprising brain circuit, so she had to change the topic:

"Okay, let's get started."

This is the first time Ning Chen and Song Xiyun have actually run together at night after attending a training camp at Shuimu University.

This time, both of them seemed very motivated and had almost no reservations.

As Ning Chen said, he has indeed made great progress during this period.

Even if Song Xiyun didn't hold back, she still couldn't throw Ning Chen far away.

In the end, the time it took for the two people to complete 5,000 meters only differed by a few seconds.

"Okay, if I let you run for ten seconds first, maybe you will really beat me."

Song Xiyun said jokingly while panting heavily.

Ning Chen saw Song Xiyun's appearance and knew that Song Xiyun really tried his best this time.

Being able to force out the strongest Song Xiyun is enough to show that Ning Chen now has a certain level of long-distance running ability.

"So, do you feel a little regretful for cultivating such a powerful opponent for yourself?" Ning Chen said with a smile.

"It's good to surpass me. After all, it's better to be better than the old."

"Huh? Why doesn't it sound like you're complimenting me?"

"Of course I'm complimenting you, don't think too much."

Ning Chen was finally able to run at night with Song Xiyun in person again. Ning Chen felt in a good mood, and the happy time at Shuimu University was back.

After returning to the dormitory, taking a shower, and previewing tomorrow's classes for a while, Ning Chen went to bed to rest, preparing to start his study and life at Yanda in the best possible condition tomorrow.

…

In the following days, Ning Chen followed the plan and audited many science courses at Yanda.

The courses Ning Chen selected were all graduate-level courses. Judging from the professional ability and teaching level of the teachers, they were indeed better than the teachers at Shengzhou University as a whole.

After a round of auditions, Ning Chen selected some of the courses he was most satisfied with as his focus in the future.

The news about Ning Chen's exchange studies at Yan University gradually spread in Yan University.

After all, Ning Chen is also very famous in Yanjing University because of his various previous deeds. When Ning Chen enters the classroom to listen to classes, he often attracts the attention of some students.

However, as this situation occurred many times, everyone gradually became accustomed to it.

Among these courses, Ning Chen's favorite course was the quantum physics course taught by a physics professor at Yanda named Ren Mingshan.

Not only does this professor have excellent professional abilities, he has published dozens of papers in major academic journals at home and abroad, but his teaching style is also very interesting and humorous, and is not limited to the knowledge in textbooks.

Ning Chen would often engage in some expanded thinking while listening to Ren Mingshan's classes, which allowed Ning Chen to accumulate experience in physics very quickly.

On this day, in Ren Mingshan's quantum physics class, Ren Mingshan talked about the concept of "Majorana fermions".

This was not the first time Ning Chen had heard of this kind of particle, but he had never seriously studied this kind of particle before.

Majorana fermions are hypothetical particles proposed by Ettore Majorana.

Majorana believes that this particle is a fermion, and its special feature is that its antiparticle is itself.

Scientists in the academic community have different opinions on whether such particles really exist, and have not reached a unified conclusion.

And until today, there is no experiment or theory that can prove whether Majorana fermions really exist.

"Today's homework, when we go back, each student will write a short paper. The topic is to discuss whether Majorana fermions really exist, and give your reasons for doing so. There is no limit to the number of words, but the reasons must be sufficient. You cannot You guessed it by relying on some sixth sense!"

Hearing Ren Mingshan's words, the students under the podium couldn't help laughing.

But speaking of it, the difficulty of this assignment is not simple.

A first-year graduate student is definitely unlikely to be able to give an exact conclusion on something that even scientists have not yet reached a conclusion on.

But Ning Chen also knew that the reason why Ren Mingshan left such an assignment was not to really let the students solve the problem completely, but to train everyone how to explore the topic.

"Okay, class is over. After everyone has finished writing their papers, send them directly to my email. Please note your name and student number. I will read every paper carefully."

After class, Ning Chen thought about this problem while walking on the road.

Although Ning Chen only attended the class as an auditor, he was not required to complete Ren Mingshanliu's homework.

But Ning Chen will not relax his demands on himself because of this. Even if other students can do things, Ning Chen will definitely work hard to do them.

In this way, Ning Chen thought about it while walking. Until he returned to the dormitory, he still didn't stop thinking about this issue.

At this moment, Ning Chen suddenly had a new idea.

"Wait a minute... Majorana fermions seem to have a certain connection with iron-based superconductivity."

Ning Chen recalled the various experimental data he had produced during his previous experiments on iron-based superconductivity and discovered some possible connections.

"According to the energy band characterization data of various iron-based superconductors that I have measured before, it seems to be basically consistent with the signs of Dirac cone surface states..."

Thinking of this, Ning Chen opened his laptop and searched for relevant experimental data.

As Ning Chen just thought, these data are indeed completely consistent with what Ning Chen remembers, and they are also consistent with the signs of the Dirac cone surface state.

In other words, evidence for the existence of Majorana fermions may indeed be found in iron-based superconductors!

Following this train of thought, Ning Chen continued his analysis.

In this way, time passed quietly and quickly.

Even though dinner time had long passed, Ning Chen didn't notice anything and was still immersed in his own world.

Finally, after several hours of derivation, Ning Chen finally completed his entire derivation process.

"Although it is only a theoretical derivation and cannot be verified for the time being, it is at least a reasonable conjecture."

Regardless of whether this conjecture is really correct, Ning Chen is still very satisfied with his series of derivation processes just now.

But when the flow state ended, Ning Chen gradually felt hungry in his belly.

I looked at the time and saw that it was already past 8 p.m.

"No... I'm going to run with Song Xiyun soon, but I'm still hungry now." Ning Chen thought.

Although Ning Chen looked forward to running at night every day, Ning Chen couldn't go for a run hungry.

And if we go to eat now, even if we can catch up with the time, it is definitely not suitable for exercise just after eating, let alone such strenuous exercise.

Thinking of this, Ning Chen had no choice but to send a message to Song Xiyun.

"Song Xiyun, why don't you take a day off tonight?"

Soon, Song Xiyun replied:

"Why, are you feeling unwell today?"
