"Hmm...Okay, I'll heat some hot water for you right now."

Naturally, Ning Chen wasn't really thirsty, but he just used this method to divert Qi Wan's attention.

After the water is boiled, my brain has almost completed the work of organizing information.

However, Ning Chen could tell that Qi Wan still cared about him very much. Seeing that something was wrong with him, he was so nervous that he almost carried her to the hospital.

Qi Wan took a cup of boiled water and handed it to Ning Chen, and asked:

"How's it going? Are you feeling better now?"

"Well, it's much better, don't worry."

At this time, Ning Chen's brain had reached the final stage of organizing physics information, and the brain's operating power also began to decline.

Qi Wan observed Ning Chen's complexion and found that there was really no big problem, so she felt relieved.

"Ning Chen, what time do you go to bed every night?"

"Hmm... around 12 to 1 o'clock, what's wrong?"

With Ning Chen's current energy, 6 hours of sleep a day is enough. Going to bed too early will only be a waste of time.

Of course, Ning Chen does not suggest that others imitate their own schedules. After all, everyone has different energy levels.

Normally, it is best to maintain seven to eight hours of sleep a day to ensure that you have more energy the next day.

But when Qi Wan heard Ning Chen's work and rest time, she said disdainfully:

"You went to bed very early, why can't you get a good rest?"

"Huh? Qi Wan, what time do you usually go to bed at night?"

"It's two o'clock. If it's later, you'll have to stay up late."

Ning Chenxin said, Qi Wan, do you have any misunderstanding about the concept of staying up late?

However, it is true that some people are particularly energetic, and the amount of sleep they need varies from person to person.

While talking to Qi Wan, Ning Chen had already completed sorting out his physics knowledge and returned to his previous normal state.

Ning Chen only felt that his understanding of physics had risen to another level, and he also had some new ideas about current topics.

At this moment, Ning Chen suddenly thought of something, and immediately picked up the draft paper and started calculating.

"You...what happened?"

Qi Wan only felt that there was something unusual about Ning Chen today, as if it was a precursor to mutation.

Ning Chen ignored Qi Wan. In the flow state, Ning Chen had automatically blocked Qi Wan's voice.

Seeing that Ning Chen ignored her, Qi Wan felt a little baffled by this, so she simply ignored Ning Chen and continued her experiment.

After a while, Ning Chen seemed to have deduced some new theory and said to himself:

"It seems that there are still some problems with the previous formula. This is the more accurate formula for tunneling differential conductance spectrum."

Qi Wan originally didn't want to deal with Ning Chen, but after hearing Ning Chen's words, Qi Wan was a little curious as to what formula Ning Chen had just pushed on the paper.

Qi Wan struggled mentally for a while, but curiosity finally won.

"Hey, let me see the formula you proposed!"

Ning Chen didn't hesitate and handed the draft paper directly to Qi Wan.

Looking at the derivation content on Ning Chen's draft paper, Qi Wan asked in surprise:

"Ning Chen, you mean that the magnetic field will affect the measurement of the zero-voltage conductivity peak?"

"Yes, we have only ruled out the interference of magnetic scattering on the zero-voltage conductance peak, but we have not verified the relationship between the magnetic field and the zero-voltage conductance peak in detail. If my guess is correct, the zero voltage in the system The piezoelectric conductivity peak will weaken as the magnetic field increases."

"But... this doesn't help us observe a more obvious zero-voltage conductance peak. When we conducted experiments before, we didn't apply any magnetic field to the environment?"

Ning Chen did not rush to answer Qi Wan's question, but said with a smile:

"Qi Wan, think about it carefully."

Hearing what Ning Chen said, Qi Wan also thought of something.

"Ning Chen, are you saying that the geomagnetic field will also have an impact?"

Because the earth is originally a huge magnet, everything near the earth is affected by the earth's magnetic field.

It’s just that the effect of the geomagnetic field on local areas is not obvious. In many cases, the geomagnetic field can be ignored.

"This possibility does exist. Of course, we need to further prove through experiments whether the magnetic field will play a role in this and how big the specific impact is..."

Qi Wan listened to Ning Chen's explanation and kept thinking in her heart.

"Ning Chen, I also feel that your idea may be right. Then let's stop dawdling and do the experiment quickly!"

Ning Chen and Qi Wan hit it off immediately, and immediately prepared a new experiment.

In order to verify his idea faster, Ning Chen did not add a particularly strong magnetic field at the beginning. The intensity of the external magnetic field was on the same order of magnitude as the geomagnetic field, and the direction of the magnetic field was the same as that of the geomagnetic field, allowing the two magnetic fields to be in a superposition state. .

Immediately afterwards, Ning Chen and Qi Wan controlled the material to enter the superconducting state and conducted measurements on the point contact spectrum of topological superconductors.

After completing the data measurements of several sets of experiments, Ning Chen and Qi Wan couldn't wait to check the atlas data.

"Sure enough! After the external magnetic field is applied, the zero-voltage conductance peak is weaker than before."

After calculating the zero-voltage conductance peak in the point contact spectrum, Ning Chen and Qi Wan determined this conclusion.

"Ning Chen...are we really going to discover Majorana fermions?"

"It's hard to say, but at least we are getting closer to the result. Qi Wan, we may have to do a few more sets of experiments in the past few days so that we can draw more accurate conclusions."

When he heard about the experiment, Qi Wan did not resist at all, but said expectantly:

"Okay, okay, I'm absolutely fine, I can do experiments all night long!"

"There's no need to be so exaggerated. Just go back a little later than usual."

This kind of experiment will not make Ning Chen forget about food and sleep, but his recent night running activities may have to be suspended for a few days.

Ning Chen sent Song Xiyun a message on QQ, telling herself that she would be busy with experiments these days and would not go for a run in the evening.

Song Xiyun responded with a "frown" expression, and it was obvious that Song Xiyun felt a little disappointed about Ning Chen's affair with her.

"When I finish my work for a while, I'll treat you to dinner in a few days." Ning Chen replied again.

"Then I'll have to eat something more expensive this time."

"No problem, you can eat salmon roe dry."

Before doing the experiment in the evening, Ning Chen and Qi Wan went to the cafeteria to eat a bowl of noodles, and then returned to the laboratory to continue the experiment.

After measuring several sets of experimental data, Ning Chen's previous inferences were further verified.

"As the intensity of the external magnetic field continues to increase, the peak value of the zero-voltage conductivity peak becomes weaker and weaker. When the last set of data was measured, the zero-voltage conductance peak was almost impossible to identify with the naked eye."

Such a weak zero-voltage conductivity peak can only be seen after enlarging the spectrum.

In order to further confirm this conclusion, Ning Chen and Qi Wan measured many sets of experimental data in the next two days.

These data were all in line with Ning Chen's previous inferences, which made Ning Chen more sure of his idea.

"Qi Wan, I think we can try to shield the geomagnetic field. This time, we might be able to measure the most obvious primary zero-voltage conductivity peak."
