Chapter 341: This kid doesn't seem that steady after all

At 7:00 PM, the twilight had already grown quite thick. The lights on the sports field were bright, with some people making their final sprints on the track, and a girl holding a guitar singing—as lively as ever.

In a corner, two young people who had just finished exercising sat down to catch their breath. A light breeze brushed by, carrying the chill of early spring.

Xu Qingzhou pinched his biceps, estimating that if he kept training, he would have visible muscles sooner or later. He could already finish 5 kilometers in under 30 minutes now, which was countless times better than the "skinny dog" state of his previous life.

Beside him, Song Yao looked at her cocky boyfriend, shook her head helplessly, and tossed her jacket over. "Put your clothes on."

"I'm still sweaty," Xu Qingzhou said.

"Put it on even if you're sweaty. You'll catch a cold in the breeze."

"I won't. My body is very strong."

Although Xu Qingzhou muttered, he still obediently put on the jacket. He vaguely remembered that the last time he was sick seemed to be during the high school physics competition, when his fever hit 39 degrees. He hadn't been sick since then.

After resting on the field for 10 minutes, the two stood up, ready to go home. By the time they pushed the door open and entered, they were each holding a cup of hot milk tea.

Back home, Song Yao leaned on the sofa, biting on her straw, her large eyes darting toward Xu Qingzhou.

Xu Qingzhou turned his head, and the school beauty Song quickly looked away. He asked with a smile, "Is it good?"

Song Yao nodded affirmatively, even showing an expression of enjoyment. "The taste is quite good. It has the fragrance of tea and the scent of the milk cap. Do you want to swap with me?"

"Really?" Xu Qingzhou didn't believe it at all. Tieguanyin peanut milk cap—it didn't sound good just by the name. This girl was probably thinking about how to swap with him.

"If it's so good, why have you only drunk so little?"

Looking at the cup, she had only drunk one-fifth.

"You have to savor it slowly if it's good." Song Yao took a big sip to prove her point.

Xu Qingzhou cooperated and said, "Let me have a sip."

"So much trouble. Here, you drink this, I'll drink yours."

Song Yao muttered, took Xu Qingzhou's milk tea, and shoved her own into his hands.

Xu Qingzhou took a sip, and as expected, a strange, peculiar taste immediately rushed into his mouth.

He continued to cooperate, feigning that he had been tricked: "It's not good. Swap back."

"No swapping. This is mine."

Song Yao guarded the milk tea tightly. She had originally wanted to try a new product, but didn't expect to fall into a trap again.

Fortunately, she had a boyfriend.

Although this guy seemed to have already seen through her terrible acting.

"Really not swapping?"

"Not swapping!"

"Really not swapping?"

"No."

"Then I'm going to drink something else." Xu Qingzhou aimed his gaze at the school beauty Song's chest.

Song Yao immediately understood this guy's lewd thoughts, but since she was in the wrong first, she could only threaten, "If you dare to come over, I'll kick you."

"Then I'll really have to try." Xu Qingzhou rubbed his hands.

"Xu Qingzhou!"

Xu Qingzhou didn't try in the end, fearing he would get beaten. Drinking the milk tea, he went to pour cat food for Er Miao, then finished the milk tea in a few large gulps and said, "I'm going to take a shower."

"Oh, okay."

"Want to go together?" Xu Qingzhou issued an invitation.

"No."

Song Yao refused ruthlessly.

Xu Qingzhou said, "We can save water together. Song Yao, you don't think I want to do anything else, do you? That would be wronging me. It's just a simple shower."

The foolish Xu Qingzhou used a foolish excuse.

Song Yao secretly despised Xu Qingzhou. He knew he would be refused and yet he still asked.

"Song Yao."

"Hmm?" Song Yao blinked her eyes at him.

Xu Qingzhou's expression was sorrowful: "We've been together for so long, I didn't expect that there's still no trust between us. I'm very sad."

Song Yao lowered her head again, gave a nonchalant "hmm," and happily sipped her milk tea, watching a funny video Ding Jiahui had shared with her.

Xu Qingzhou couldn't keep acting, so he flicked his sleeves and left.

At 8:30 PM, Song Yao went in to shower. Xu Qingzhou sat at the desk, took out a manuscript from the side, and pondered where to start regarding physics.

Academician Chu Jiangfeng was currently engaged in research on the estimation of solutions to nonlinear wave equations and scattering theory regarding the generalized Strichartz inequality, and couldn't provide too many substantive answers.

The remaining content still required him to explore on his own.

Currently, the more popular research fields were quantum communication, quantum entanglement (superposition states), and the development of quantum computers, but public opinion seemed very focused on quantum entanglement and "various quantizations."

Properties like quantum tunneling and coherence were not often mentioned, and Xu Qingzhou currently had no intention of doing research in that area.

Of course, there was also quantum transmission, which the Xia Nation was focusing on.

Xu Qingzhou tapped his fingertips lightly, pondered for a moment, picked up a pen, and began to draw a mind map on the draft paper.

Branches of quantum mechanics: quantum communication, quantum entanglement...

In terms of particle physics: quark resonance state analysis, signs of supersymmetric partner particles, strong interaction research...

Or, start from material physics?

Xu Qingzhou paused.

He was quite interested in the field of lithium-ion batteries.

After carefully considering for a few minutes, Xu Qingzhou shook his head again and passed on this idea. Doing such research required a large number of experiments, and he had neither the personnel nor the funds. Furthermore, although he had read a lot of materials, his understanding of this stuff was insufficient.

Hearing the sound of water in the bathroom stop, Xu Qingzhou got up to get the hairdryer to help the school beauty Song dry her hair.

15 minutes passed.

"Done." Xu Qingzhou went to put away the hairdryer, and when he returned, he saw Song Yao grooming her hair. Following her movements, her pajamas were trembling slightly.

Seeing her boyfriend looking at her lecherously, Song Yao raised her eyebrows and made a gesture of digging out eyeballs.

Xu Qingzhou sighed in his heart; the school beauty Song was still the school beauty Song, as violent as ever.

After sighing, he asked, "Is the thesis going smoothly?"

Starting in February, Song Yao had been writing a thesis titled "Motivation and Impact of Tencent's Physical Dividends from the Perspective of Strategic Transformation."

"Hmm, I'll be able to finish it next month."

"Really amazing."

"Xu Qingzhou, your vocabulary for praising your girlfriend is too lacking."

"Intelligent and peerless, naturally beautiful, clever as ice..."

At 11:00 PM, Xu Qingzhou stared at the full manuscript and circled one of them.

【AB effect.】

The AB effect shows that in an electromagnetic field, charged particles can be affected by the electromagnetic potential in these regions, including the vector potential A and the scalar potential φ, even if they do not pass directly through certain regions.

That is, the electromagnetic vector potential can produce an observable effect in quantum mechanics, rather than being a vase as in classical electromagnetic theory. Of course, this vase is top-tier blue and white porcelain.

After all, in classical electromagnetic theory, the electromagnetic potential is indeed just an auxiliary variable used to describe the changes in electric and magnetic fields, but it does not have direct physical significance itself.

The reason Xu Qingzhou chose this, besides interest, was also because this stuff was connected to quantum entanglement and quantum coherence.

Once, Xu Qingzhou had spent all his energy on quantum information communication, but he had only scratched the surface of the AB effect.

People in academia often pursue 100% success, but as someone who needed to apply technology to actual equipment, he still couldn't achieve perfection. Besides quantum physics, the AB effect also seemed to provide a theoretical basis for researching and preparing new materials with special properties, and it also involved content such as topological insulators and the quantum Hall effect in condensed matter physics.

The next day was another sunny day.

Early in the morning, the brilliant sunlight passed through the branches of the trees, falling brightly onto the wet asphalt road, reflecting beautiful light spots. Under the shade of the trees, two young people walked slowly.

"Xu Shi, are you really not going to persist a bit longer?" This guy had been grinding for three days, but suddenly gave up, saying he wanted to do physics. This made Song Yao, as his girlfriend, a bit worried about whether he had been hit hard.

Although he didn't look discouraged at all.

Xu Qingzhou shook his head: "No, recognize reality, give up illusions."

"But aren't you usually quite persistent?"

"Song Laoshi, I reasonably suspect you are driving."

*Pia~*

Xu Qingzhou took a slap.

"Okay, okay, okay, I won't shout anymore. You hurry up and go. I'll come pick you up tonight, Song Laoshi~"

Before Song Yao could make a move, Xu Qingzhou had already greased his soles and run away.

【In one look...】

Song Yao curled her lips. This person was too annoying, but the more annoying he was, the more it meant he was normal. She felt relieved in her heart and turned to walk toward the Economics Academy.

The two separated at the intersection in front of the Economics Academy.

Inside the black Audi A6 in the distance, Li Daiyue shook her head slightly. This student of hers... perhaps only in front of Xu Qingzhou would she show such an active side.

These two young people were not bad; they were quite suitable.

Li Daiyue drove, and the speed was naturally faster. Seeing Song Yao enter the office, she said directly: "Xiao Yao, this is the information for the new project. Familiarize yourself with it as soon as possible."

She handed over a USB drive. Only when seeing this student of hers would the wrinkles at the corners of her eyes smooth out a little.

Song Yao nodded and took the USB drive.

"Looking at Xia Nation's trade with the US from the perspective of overproduction: time series accounting, driving force analysis, and strategic research."

This was a new topic that had been in preparation for a month.

As soon as Song Yao sat down, Li Daiyue asked with a smile: "How is your thesis coming along?"

As someone who studied economics, she was quite sensitive to these things.

She could clearly perceive that the trade friction between the Xia Nation and the United States was increasing.

Li Daiyue's current cultivation strategy for this student of hers was to first understand the competition between macro-finance, and then conduct case analysis from a more detailed micro-perspective.

"I have already completed the second point of the case analysis."

Song Yao sent the document to Li Daiyue.

【2. Analysis of physical dividend motivation based on the perspective of strategic transformation.】

【Usually, physical dividends are an expedient measure when a company has insufficient cash and needs to maintain a relatively stable dividend payment level for shareholders.】

Li Daiyue finished reading quickly and nodded slightly: "No problem, just write according to your train of thought."

"Okay."

Li Daiyue paused, but still asked: "I saw Xu Qingzhou drop you off."

After all, he was her student's boyfriend, so she wanted to understand the situation.

"Hmm." Song Yao nodded.

"He is researching harmonic analysis, right?" Li Daiyue now had a good impression of Xu Qingzhou. He was young, quite steady, and had a maturity that surpassed his peers.

"Currently..."

Song Yao didn't deceive Li Daiyue: "It's temporarily stopped. He said he wanted to study physics for a while first."

Li Daiyue was stunned and suddenly wanted to take back her exclamation just now. This kid didn't seem that steady after all. Is a research field something you can just change whenever you want?

Separating from Song Yao, Xu Qingzhou went directly to the library to look up relevant materials.

After sitting down in the library, the first thing Xu Qingzhou found was the original paper published by Aharonov and Bohm in 1959, titled "Significance of Electromagnetic Potentials in Quantum Theory" in Chinese.

Besides that, there were Dirac's "The Principles of Quantum Mechanics" and Jackson's "Classical Electrodynamics."

The AB effect involved concepts such as phase changes and wave function interference, which were the most basic things in quantum mechanics, so Xu Qingzhou was under no pressure.

On the third day, Xu Qingzhou came to Chu Jiangfeng's office again.

Chu Jiangfeng waved his hand, signaling Xu Qingzhou to sit down, and asked while drinking tea: "How far have you gotten with your work during this time?"

"Still summarizing the materials on the AB effect."

"What stuff?" Chu Jiangfeng's hand holding the tea paused, and a hint of confusion appeared on his face. Is there this thing in harmonic analysis?

Xu Qingzhou remembered that he hadn't had time to tell Academician Chu about his recent arrangements, so he explained that he had encountered a bottleneck in the research on the local smoothness problem and was prepared to put it aside for now.

"You want to study physics?"

Hearing Xu Qingzhou say he planned to do physics first, both Chu Jiangfeng and Yang Yongze were stunned.

"Hmm." Xu Qingzhou nodded, smiled, and said: "The stuck point is too serious, so I'm changing fields to relax my brain."

"..."

Chu Jiangfeng and the other were silent again.

Especially Yang Yongze, who looked at Xu Qingzhou with a complex expression.

What do you mean by changing fields to relax your brain?

Is this relaxing your brain?

This is clearly increasing the intensity for yourself, okay!

Yang Yongze felt that Xu Qingzhou was too willful. It was very difficult to take root in a new field. Take Xu Xu Shidi, for example: a number theory genius, but once he reached the field of harmonic analysis, didn't he hit a wall and couldn't continue his research?

Changing fields, there was a 90% chance he would get stuck again.

From number theory to harmonic analysis, and now to the AB effect in physics.

In just a few months, he had changed three directions. No matter how you look at it... it seems a bit unreliable.

Is this the willfulness of a genius?

Chu Jiangfeng was slightly calmer because he himself was involved in many fields. After a slight silence, he asked directly: "Regarding physics, which direction did you just say you wanted to engage in research?"

Xu Qingzhou said: "The AB effect."

"The AB effect?" Chu Jiangfeng searched his knowledge and shook his head helplessly. "In the field of physics, I have always known very little, and I have even less impression of this. However, have you thought it through yourself?"

"Thought it through. Anyway, there is no progress in mathematics right now. Changing a thinking mode and coming back to study it after a while might yield unexpected gains."

Xu Qingzhou said with a smile.

"Alright then, as long as you have thought it through, kid." Chu Jiangfeng nodded slightly: "However, before that, we can take a look at the places where you encountered problems together."

Xu Qingzhou took out the formulas he couldn't calculate.

After staying in Chu Jiangfeng's office for two hours, Xu Qingzhou got up and left. The three of them had ground away for half a day without any results.

In the office, Yang Yongze felt a bit emotional and said: "Professor, you didn't even persuade Xu Xu Shidi."

Chu Jiangfeng said with a smile: "Young people, they have enough trial-and-error costs now, so it's good to try more. Once they hit a south wall, their hearts will settle down."

Yang Yongze suddenly realized, thinking to himself that it turned out the professor had this plan. It makes sense; Xu Xu Shidi has achieved success at a young age, so he should encounter some setbacks.

Hitting a nail here and there is a taboo for those of them who do research.
