Chapter 341 This kid doesn't seem that calm It was 7 o'clock in the evening and the dusk was already thick. The lights on the playground were bright. Some people were making the final sprint on the track. Some girls were singing with guitars and it was as lively as ever. In the corner, two young men who had just finished exercising sat down to take a break. The breeze was blowing gently, bringing the chill of early spring. Xu Qingzhou pinched his biceps, figuring that if he continued to practice, he would have noticeable muscles sooner or later. Now he could run 30 kilometers in 5 minutes, which made him many times stronger than the skinny dog in his previous life. Next door, Song Yao looked at her arrogant boyfriend, shook her head helplessly, and threw her coat over, "Put on your clothes." "I'm still sweating." Xu Qingzhou said. "You have to wear it even if you are sweating. It is easy to catch a cold if you are exposed to cold wind." “No, I’m very strong.” Although Xu Qingzhou grumbled, he still obediently put on his coat. He vaguely remembered that the last time he was sick was during a physics competition in high school. His temperature reached 39 degrees. He hasn't been sick since then. After resting on the playground for 10 minutes, the two got up and prepared to go home. When they pushed the door open, they both had cups of hot milk tea in their hands. After returning home, Song Yao leaned on the sofa, biting a straw, glancing at Xu Qingzhou with her big eyes.
Xu Qingzhou turned around, and School Beauty Song quickly looked away. He smiled and asked, "Is it delicious?" Song Yao nodded affirmatively, even revealing an expression of enjoyment, "It tastes very good, with the aroma of tea and milk cap. Do you want to exchange with me?" "Is this true?" Xu Qingzhou didn't believe it at all. The name of Tieguanyin peanut milk cap sounded bad. This girl was probably thinking about how to exchange it with him. "It tastes so good that you only drank a little?" Looking at the cup, he had only drunk one fifth of it. "Good food should be enjoyed slowly." Song Yao took a big sip to prove her words. Xu Qingzhou cooperated and said, "Give me a sip." "It's such a hassle. I'll give you some and I'll drink yours." Song Yao muttered, took Xu Qingzhou's milk tea, and stuffed her own milk tea into his hand. Xu Qingzhou took a sip, and as expected, a strange taste immediately rushed into his mouth. He continued to cooperate, pretending to be deceived: "It doesn't taste good, change it back." "No, this is mine." Song Yao protects her milk tea to death. She originally wanted to try a new product, but unexpectedly fell into the trap again. Fortunately, I have a boyfriend. Although this guy seems to have realized his poor acting skills. "You really don't want to change?" "Don't change!" "You really don't want to change?" "Do not."
"Then I'll have to drink something else." Xu Qingzhou glanced at the school beauty Song's chest. Song Yao immediately understood the guy's dirty thoughts, but she was in the wrong first, so she could only threaten: "If you dare to come over, I will kick you." "Then I'll really give it a try." Xu Qingzhou rubbed his hands. "Xu Qingzhou!" Xu Qingzhou didn't try in the end, fearing that he would be beaten. He drank his milk tea and poured cat food for Er Miao. Then he drank the milk tea in a few big gulps and said, "I'm going to take a shower." "okay." "Would you like to join us?" Xu Qingzhou invited. "No." Song Yao refused mercilessly. Xu Qingzhou said, "Let's save water together. Song Yao, you don't think I want to do something else, do you? That would be unfair. I just want to take a shower." Stupid Xu Qingzhou used stupid excuses. Song Yao secretly despised Xu Qingzhou for asking even though she knew she would be rejected. "Song Yao." "Hmm?" Song Yao blinked and looked at him. Xu Qingzhou looked sad: "We have been together for so long, but I didn't expect that there is still no trust between us. I am very sad." Song Yao lowered her head again, said "hmm" nonchalantly, took a sip of milk tea happily, and was watching the funny video that Ding Jiahui shared with her. Xu Qingzhou couldn't act anymore and left in anger. At 8: in the evening, Song Yao went in to take a shower. Xu Qingzhou sat down at the table, took out a manuscript from the side, and thought about where to start with physics. Academician Chu Jiangfeng is currently conducting research on the estimation and scattering theory of solutions of the generalized Strichartz inequality in nonlinear wave equations, but cannot provide many substantive answers. The rest of the content still needs to be explored by himself. At present, the more popular research fields include quantum communication, quantum entanglement (superposition state) and the development of quantum computers, but public opinion seems to be very concerned about quantum entanglement and "various quantizations." Properties such as quantum tunneling and coherence are not often mentioned, and Xu Qingzhou currently has no intention of doing research in this area. Of course, there is also quantum transmission, which is the focus of Xia Guo’s research. Xu Qingzhou tapped his fingertips lightly, thought for a moment, picked up the pen and began to draw a mind map on the manuscript paper. Branches of quantum mechanics include quantum communication and quantum entanglement. In particle physics, analysis of quark resonance states, signs of supersymmetric partner particles, and research on strong interactions Or, starting from the physics of materials? Xu Qingzhou paused. He is very interested in the field of lithium-ion batteries. After thinking carefully for a few minutes, Xu Qingzhou shook his head again and rejected this idea. Such research requires a lot of experiments, and there is no personnel or funds. Moreover, although he has read a lot of information, his understanding of this thing is insufficient. After hearing the sound of water running in the bathroom stop, Xu Qingzhou stood up and got the hair dryer to help School Beauty Song blow dry her hair.
15 minutes passed. "Done." Xu Qingzhou went to put down the hair dryer, and when he came back, he saw Song Yao fixing her hair. As she moved, her hair was trembling slightly under her pajamas. Seeing her boyfriend looking at her with lustful eyes, Song Yao raised her eyebrows and made a gesture as if digging out her eyes. Xu Qingzhou sighed in his heart, School Belle Song is still School Belle Song, as violent as ever. After expressing his feelings, he asked, "Is the thesis going well?" Since February, Song Yao has been writing a paper titled "The Motivations and Impacts of Penguin In-Kind Dividends from the Perspective of Strategic Transformation." "Well, I'll be able to finish it next month." "awesome." "Xu Qingzhou, you don't have enough words to praise your girlfriend." "Extremely intelligent, naturally beautiful, and extremely smart." At 11 o'clock in the evening, Xu Qingzhou stared at the full manuscript paper and circled one of them. 【AB effect.】 The AB effect shows that in an electromagnetic field, even if charged particles do not pass directly through certain areas, they can be affected by the electromagnetic potential in these areas, including the vector potential A and the scalar potential φ. That is, the electromagnetic vector potential can produce an observable effect in quantum mechanics, rather than a vase in classical electromagnetic theory. Of course, this vase is top-grade 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 itself does not have direct physical meaning. The reason why Xu Qingzhou chose this, in addition to his interest, is because it is also related to quantum entanglement and quantum coherence. Once upon a time, Xu Qingzhou devoted all his energy to quantum information communication, but only dabbled in the AB effect. Academics often pursue 100% success, but as people who need to apply technology to actual equipment, they still cannot achieve perfection. In addition to quantum physics, the AB effect seems to provide a theoretical basis for the research and preparation of new materials with special properties, and also involves topological insulators and quantum Hall effect in condensed matter physics. The next day was another sunny day. Early in the morning, the bright sunshine passed through the branches of the trees and fell brightly on the wet asphalt road, casting beautiful spots of light. Under the shade of the trees, two young people were walking slowly. "Teacher Xu, are you really going to hold on a little longer?" This guy persisted for three days, but suddenly gave up and said he wanted to study physics. This made his girlfriend Song Yao a little worried that he might have been defeated. Although he didn't look discouraged at all. Xu Qingzhou shook his head: "No, face the reality and give up the fantasy." "But aren't you usually very persistent?" "Mr. Song, I reasonably suspect that you are driving." pia~ Xu Qingzhou got hit hard. "Okay, okay, I won't yell anymore. Just go ahead and I'll pick you up in the evening, Teacher Song~" Before Song Yao took action, Xu Qingzhou had already run away. Song Yao curled her lips. This guy was too annoying. But the more annoying he was, the more normal it was. She breathed a sigh of relief and turned to walk towards the School of Economics.
The two separated at the intersection in front of the seminary. In the black Audi A6 in the distance, Li Daiyue shook her head slightly. This student of hers might only show such an active side in front of Xu Qingzhou. These two young men are pretty good and are a good match. Li Daiyue drove faster of course. When he saw Song Yao entering the office, he said directly: "Xiaoyao, this is the information of the new project. You should familiarize yourself with it as soon as possible." She handed over the USB flash drive, and only when she saw her student did the wrinkles on her brows relax a little. Song Yao nodded and took the USB drive. Xiaguo's trade with the United States from the perspective of overproduction: time series accounting, driving force analysis, and strategic research. This is a new topic that I have been preparing for a month. As soon as Song Yao sat down, Li Daiyue asked with a smile: "How is your paper going?" As someone who studies economics, I am quite sensitive to these things. It can be clearly felt that the trade friction between Xia and the United States is increasing. Li Daiyue’s current training strategy for his student is to first understand the competition between macro-financial sectors, and then conduct case analysis from a more detailed micro perspective. "We have completed point 2 of the case study." Song Yao sent the file to Li Daiyue. 【2. Analysis of the motivation for dividends in kind based on the perspective of strategic transformation. 】 [Generally speaking, dividends in kind are a stopgap measure when a company is short of cash but needs to maintain a relatively stable level of dividend payments to shareholders.] Li Daiyue finished reading it quickly and nodded slightly: "No problem, just write according to your ideas." "it is good." Li Daiyue paused, then asked, "I saw Xu Qingzhou sent you here." After all, he is my student’s boyfriend, so I need to understand his situation. "Yeah." Song Yao nodded. "He is studying harmonic analysis, right?" Li Daiyue now has a good impression of Xu Qingzhou. He is young, relatively steady, and has a maturity that surpasses his peers. "Now." Song Yao did not lie to Li Daiyue, "He stopped temporarily. He said he wanted to study physics for a while first." Li Daiyue was stunned and suddenly wanted to take back his previous sigh. It seems that this boy is not that calm. Can he change his research field just like that? After separating from Song Yao, Xu Qingzhou went directly to the library to look up relevant information. After sitting down in the library, the first thing Xu Qingzhou found was the original paper published by Aharonov and Bohm in 1959, which is called "The Importance of Electromagnetic Potential in Quantum Mechanics" in Chinese. In addition, there is Dirac's "Principles of Quantum Mechanics" and Jackson's "Classical Electrodynamics".
The AB effect involves concepts such as phase change and wave function interference, which are the most basic things in quantum mechanics. Xu Qingzhou does not feel any pressure. On the third day, Xu Qingzhou came to Chu Jiangfeng's office again. Chu Jiangfeng waved his hand to signal Xu Qingzhou to sit down, and asked while drinking tea: "How busy have you been recently?" "We are still compiling data on the AB effect." "What is that?" Chu Jiangfeng paused while drinking tea, a hint of confusion appeared on his face. Is there such a thing in the blending analysis? Xu Qingzhou just remembered that he had not had time to tell Academician Chu about his recent arrangements, so he explained that his research on the local smoothness problem had encountered a bottleneck and he planned to put it aside for the time being. "You want to study physics?" When Chu Jiangfeng and Yang Yongze heard Xu Qingzhou say that he planned to study physics first, they were both stunned. "Yeah." Xu Qingzhou nodded, smiled, and said, "It's too difficult. Change to another field to relax your brain." "." Chu Jiangfeng and the other person fell silent again. Especially Yang Yongze, who looked at Xu Qingzhou with a complicated expression. What does it mean to change your field and relax your mind? Is this to relax the brain? This is clearly to increase your intensity! Yang Yongze felt that Xu Qingzhou was too willful and it was very difficult for him to take root in a new field. For example, Junior Brother Xu was a number theory genius, but he still ran into a wall when it came to the field of harmonic analysis and could not continue his research. If you change to another field, 90% of the time you will get stuck. From number theory to harmonic analysis, now we have come to the AB effect in physics. In just a few months, it changed directions three times. No matter how you look at it, it seems a bit unreliable. Is this the willfulness of genius? Chu Jiangfeng was a little calmer, because he himself was involved in many fields. After a brief silence, he asked directly: "As for physics, what direction did you say you wanted to study?" Xu Qingzhou said: "AB effect." "AB effect?" Chu Jiangfeng searched for knowledge and shook his head helplessly. "I know very little about the field of physics, and I have no impression of this. But have you thought it through?" "Think it through. Anyway, there is no progress in mathematics right now. I will change my mindset and come back to study after a while. Maybe I will get some unexpected results." Xu Qingzhou said with a smile. "Okay, just think it through." Chu Jiangfeng nodded slightly: "But before that, we can look at the problem you are facing together." Xu Qingzhou took out the equation that he couldn't figure out. After staying in Chu Jiangfeng's office for two hours, Xu Qingzhou also got up and left. The three of them argued for a long time but to no avail. In the office, Yang Yongze said with some emotion: "Professor, why don't you try to persuade your junior fellow student?"
Chu Jiangfeng said with a smile: "Young people now have enough trial and error costs, so it's better to try more. When you hit a wall, your heart will settle down." Yang Yongze suddenly understood and thought that this was the professor's plan. It made sense. Junior Brother Xu had achieved success at a young age, so it was natural for him to encounter some setbacks. It is a big taboo for those who do research to hit the nail on the head.
