Chapter 226 Isn't This My Future Nephew and Son-in-Law? (23, please subscribe)

The most eye-catching conference in the domestic physics community has begun, and the first session is just for everyone to sit together and chat, and talk about their own current fields and insights in other fields. The scene is relatively harmonious.

"Academician Chu."

"As we all know, you have a deep background in the field of condensed matter." The host smiled and asked Academician Chu who was sitting next to him: "It happens that there is a scientist in this field in the audience, please ask me to ask you for an answer. Two kinds of excitations of a two-component Bose superfluid. What do you think about density excitation and spin excitation?"

"what"

"That's a question." Academician Chu smiled and said seriously: "It seems that the person who can raise this question must not be an ordinary person."

"First of all, in the Bose-Einstein condensate, due to the interaction between atoms, it will lead to collective excitation similar to phonons in the lattice. This collective excitation is called Bogoliubov excitation, which was proposed by the physicist Bogoliubov. The microscopic model , and deduced the energy expression of the system by the method of canonical transformation."

"Then Li, Huang, and Yang discovered a term beyond the mean field in the energy formula, which is called the LHY term, and then discovered the basic properties of the two-component Bose gas, thereby extending the Bogoliubov theory and obtaining two a collective stimulus."

Speaking of which,
Academician Chu paused for a while, then stared at everyone present with the microphone, and continued: "The excitation of the two branches of the two-component Bose condensate is related to the oscillation behavior of its total density and the difference between the densities. When the momentum is small, their dispersion relationship is linear, which is similar to the behavior of phonons."

"But when there is coherent coupling in the two-component condensate, the number of particles in each component is not conserved, and the massless total density branch is protected by the zero mass theorem. In this way, the spin branch requires a finite size the quality of."

at the same time,

Fang Hao, who was sitting in the corner, listened to Academician Chu's speeches there, and somewhat agreed with him in his heart, putting aside personal grievances. In fact, Academician Chu is very powerful in the academic world, and his views on dispersion relations , which is completely consistent with itself.

Fang Hao glanced at the people in the audience, and saw that everyone was listening to Academician Chu's content with fascination. He couldn't help thinking that he was at the mathematics exchange meeting of the Paris Normal University a while ago.
"Actually, I think the spin excitation may be due to the effective mass." Academician Chu said with a smile: "Of course I haven't done any research on this aspect, just a blind guess."

As soon as the voice fell,
Academician Chu looked at Fang Hao who was on the far side.

"I remember that Professor Fang is also a researcher in the field of condensed matter physics, and he is also a very powerful researcher. I don't know if Professor Fang has any unique understanding of my views." Academician Chu asked with a smile.

In an instant,
The eyes of many scientific researchers in the audience moved to Fang Hao's body in unison, and there seemed to be a faint smell of gunpowder smoke in the air.

"Professor Fang?"

"What do you think about this?" The host tactfully threw the question to Fang Hao, and a staff member hurriedly handed Fang Hao a microphone from the backstage.

Fang Hao, who got the microphone, said blankly: "I don't agree with Academician Chu's point of view."

words fell,

The whole venue became lively in an instant, and everyone began to whisper to each other.

"It's up! It's up!"

The middle-aged man who predicted the physical confrontation earlier said excitedly: "Sure enough, I didn't expect it. I just didn't expect it to be so fast. I thought that the conflict would break out in the second link. In the end, I came up and went straight to Wang Bo. The professor objected to academician Chu's point of view, it's a showdown."

The companion beside him hesitated for a while and asked curiously: "But I think Academician Chu's point of view is correct."

"I think so."

"Of course."

"Maybe Professor Fang Hao has his own opinion, let's listen to Professor Fang Hao's point of view first." The middle-aged man said.

At this time,

The most surprising one belonged to Academician Chu. He didn't expect Fang Hao to directly deny his point of view. Could it be that his point of view was wrong?Impossible, absolutely impossible!This problem has also been studied by myself, and it is impossible for there to be mistakes.

After all, the host has received professional training, and in the face of such an unexpected situation, he hastily made his own response.

"Oh?"

"Professor Fang, can you put forward your point of view?" The host said, "I think everyone, including Academician Chu, would like to know your point of view."

"I think this spin excitation should be caused by the effective mass effect caused by coherent coupling." Fang Hao said seriously: "It's not simply because of the effective mass."

finished,

There was another uproar on the scene.

And some senior researchers in related fields couldn't help frowning. They kept chanting Fang Hao's words.

Effective mass effect due to coherent coupling?
On the surface, it seems that Fang Hao just supplemented Academician Chu's point of view, but in fact he strongly refuted Academician Chu's remarks. Don't look at just adding coherent coupling, which is a completely different result.

"Cough cough."

"Does Professor Fang have any theories to support his point of view?" Academician Chu asked blankly: "I have already presented theories about my point of view before, and I hope...Professor Fang can do the same."

"of course."

Fang Hao smiled, and said casually: "I give the view of effective mass effect caused by coherent coupling. It's not groundless, just to refute, because science does not allow such a situation to happen, even if Academician Chu is from the Qing University Department people."

For a time,

There was a little laughter in the hall.

"actually."

"For this problem, I have thought about my idea. Using the cycle to drive the transverse trapping potential, in this way. It will produce a parametric resonance, and this parametric resonance is a Faraday wave, so that the density and spin excitation can be completed. Perfect measurement conditions."

"As for the experiment."

"I haven't done it, but according to my model theory, I can calculate the power spectral densities of the two excitations. Relatively, I also get the power spectral densities when there is no coherent coupling and when there is coherent coupling."

"Approximately extrapolating the spin excitation-induced mass effect."

Speaking of which,
Fang Hao looked at Academician Chu not far away, and asked kindly, "Academician Chu, what do you think?"

Facing the rhetorical question from Fang Hao, Academician Chu was a little at a loss. Based on the theory he got from Fang Hao's mouth, combined with his own understanding of this field, it seemed that his point of view was more correct, and he did not consider it so perfect. Degree.

Obviously a complete failure.

Academician Chu smiled awkwardly, and said helplessly: "It seems that Professor Fang is better."

Hear this,
The people below fell into an eerie silence.

Especially those who belonged to the Qing University looked at Academician Chu in disbelief. They never expected that in the first confrontation with Fang Hao, Academician Chu would be completely defeated without any suspense.

At this time,

Fang Hao looked at the audience, and asked casually with the microphone: "I wonder if anyone wants to add something?"

Suddenly,

It's quieter.

Even academician Chu admitted that Fang Hao's point of view was more accurate, and there was no room to refute it. As for supplements, that was even more of a joke.

Fang Hao pursed his lips as he looked at nearly half of the people from the Qing University Department. There was a little helplessness and emotion in his heart, and he was a little nervous before he came. He didn't expect that there was no one who could fight at the scene, so he was nervous in vain up.

But it's also good luck. When asked about the content I'm good at, as long as the content is towards soft matter and interdisciplinary science, I may be really unlucky.

This little turmoil ended quickly, and then the host asked a few more questions, but Academician Chu obviously talked less than before, and often gave a few simple opinions, and then ended his point of view directly. As for Fang Hao .He hardly ever said anything.

however,
Even so, it still couldn't stop Fang Hao from being the most beautiful boy in the audience.

The meeting in the morning ended like this. Except for a small incident, the rest was peaceful. Of course, this also has something to do with the fact that the host did not hand the microphone to Fang Hao. interrupt.

In the beginning,
Fang Hao was very annoyed by this extremely unprofessional behavior, but after thinking about it carefully, after all, he belongs to the away game, and it is normal to be treated so unfairly.

"It's not easy to deal with."

"He's much stronger than we thought."

The five people headed by Academician Chu were sitting together. Professor Wang, an expert in quantum mechanics in China, was frowning and muttering: "If it wasn't for Xiao Jia who didn't give him the microphone all the time, I'm afraid it wasn't for the few of us." suffer, too."

"Hey"

"It's my problem. I underestimated him a bit." Academician Chu sighed, and said helplessly, "I really didn't expect Fang Hao to be so powerful, but the specific results will be known in the afternoon."

words fell,

Academician Chu asked curiously: "What do you think Fang Hao can achieve in the future?"

"academician."

"Well, I think so too."

"I think. He can even go to a higher position." Professor Zheng said thoughtfully: "The higher ups are vigorously supporting young scientists, and you have seen the strength of the support. Only there is a lack of a figure."

"Okay."

"Fang Hao turned out to be born." Professor Zheng said bitterly: "Then it can basically be concluded that Fang Hao will definitely become an image figure representing young scientists in Huaguo in the future. You must know that the power of role models is incredible, especially It has reached the level of Fang Hao."

Hearing Professor Zheng's explanation, several people present were silent. If the higher authorities confirmed that Fang Hao had become an image figure, it would mean that to a large extent, the entire domestic academic circle would be impacted. Hao's hostile attitude towards the Qing University, then the Qing University will feel very uncomfortable in the future.

"Lets see."

"Someone will stop it." Academician Chu said seriously: "This is no longer a problem of the academic circles, but of the higher-ups."

Speaking of which,

Academician Chu did not continue talking.

"Speak."

"He is a student of Mr. Yu. Mr. Yu's son married a daughter of the Zhou family, and they both have a daughter. Could it be that Fang Hao is Mr. Yu's grandson-in-law? Is he the son-in-law of the Zhou family?" Professor Wang suddenly threw out A terrible conclusion, he asked with a puzzled face.

In an instant,
The air seemed to have condensed, and everyone was taken aback by this conclusion.

"if."

"Fang Hao is really the son-in-law of the Zhou family. This... this might be tricky." Academician Chu frowned, and said silently, "Of course...I don't think it's possible, otherwise we would have been notified long ago."

"Minister Zhou."

"This is the building of our Department of Mathematics. The Department of Mathematics of Tsinghua University has a long history. At present, there are 80 teachers in the whole department, including 35 full-time seniors, 35 associate seniors, eight lecturers, and two teaching assistants."

The principal and vice-principal of the Department of Tsinghua University accompanied a middle-aged man and introduced the situation of the Department of Mathematics of Tsinghua University, followed by a large group of people, all dressed as leaders.

unconsciously,

When everyone came to the door of the physics conference, the big leader in the middle asked curiously: "What is being held here?"

"Minister Zhou is like this."

"Today is the National Physics Annual Conference led by Tsinghua University. Physics experts from all over the world gathered together, and six top experts discussed the future development of physics on the stage." the headmaster explained.

"Um"

The big leader looked at the promotional poster outside and couldn't help nodding.

suddenly,

When he saw a very familiar name, he couldn't help but froze.

This.
Isn't this the little girl's boyfriend?
"Why is this young man also a top expert?" The big leader pretended to be indifferent and asked: "It is completely different from the image of the five people next to him."

"This one?"

"His name is Fang Hao. A genius physicist and mathematician who turned out recently." The vice president of Tsinghua University said: "He has made outstanding contributions in two fields, so we invited him too, through young scientists From a different perspective, discuss and research issues together.”

The big leader nodded thoughtfully, and asked casually, "Is the meeting over?"

"The first half is over, the second half is not yet."

"The second half is still 15 minutes away." The vice president of Tsinghua University said hastily.

"That's good."

The big leader said with a smile: "Give me an inconspicuous position, and I will personally experience the content of this meeting."

For a time,

Everyone present was dumbfounded, and the vice-principal of Tsinghua University quickly said, "Mr. Zhou, is this too sudden? None of us are prepared."

"It's because it was so sudden that I'm going. If everything is ready, it's meaningless." The big leader glanced at the leaders of Tsinghua University, and then said to the secretary next to him: "Xiaotian, this afternoon The itinerary canceled two."

"Ok."

"Minister Zhou." The young man standing beside nodded his head, took out a small notebook from his pocket,

After ordering,

The big leader looked at Fang Hao's poster and thought to himself.

I never expected to meet my future nephew and son-in-law
Okay,

Take the opportunity to investigate him first.

PS: ask for a monthly ticket, ask for a recommendation ticket
