Chapter 421

To solve the multi particle problem in atoms, Xu mang knows that there is a method called self consistent, an equivalent average field. For an electron, it can be considered that it is moving in a force field. This force field is the average effect of the interaction between other electrons and atoms.

Thinking of this, Xu mang quietly stepped onto the stage, stood in front of the blackboard, picked up chalk, and began to solve the multi particle problem in the atom. By assuming the approximate electronic wave function product of the atomic ground state wave function, Xu mang obtained the expression equation of Hamilton quantity.

The emergence of the equation to solve the latter problem, under the condition of normalization, find the extreme value of H... then endless calculation.

At this time,

the students under the stage are going crazy. Looking at the back of the boy in front of the blackboard and the equations and formulas written by his chalk, he is really solving the problem raised by the professor, and he is very good at it.

"God... How did he do it?" A student looks at the blackboard with more and more contents. It's a student. It's a student. Is this a student? A freshman?

Is that the way the professor is?

Professor Jeff stood on the edge, watching Xu mang fully display his skills and smile. Fortunately, he found Professor Xu mangxu ahead of time. What a wonderful guy! Such a wonderful man is hiding among the students. I don't know what he thinks.

The calculation continued,

soon Xu mang finished the content of a blackboard. He moved the board down and then calculated.

However...

with the continuous increase of content, the students at the bottom are about to collapse, and their thoughts can not keep up with the calculation process of the great God. His calculation speed is too fast to catch up with the updated content.

"Denny... You're the best of us. How do you compare to him?" A girl asked the boy with long hair around her, "and what level has this guy reached?"

"I'm sorry."

"Yalman... I'm vulnerable in front of him." When the boy with long hair saw the young man on the stage and looked at the calculation process written on the blackboard, he felt a great sense of frustration for a time. He was already standing on the edge of autism.

When he was in high school, this Denny showed extraordinary talent in physics and mathematics. The local media also reported it crazily. Then he successfully enrolled in Columbia University's physics major. With his strong talent, he soon established a foothold among freshmen.

But... Today I met a non-human being like a human being.

"I'm afraid of his mathematical talent..." Denny said seriously, "there are some contents in this, I even contact for the first time, I can't imagine how he can achieve such a fast calculation speed, I think... There is only one existence!"

"What is existence?" Asked the girl on the edge.

"This guy... Is not normal." Denny had no choice but to smile and say: "the neuropathy that has not been cured can only do this in the fantasy of flying wildly, otherwise... I can't think of the possibility of a second existence."

Hearing the words of long hair boy Denny, the girl looked at the figure in front of her,

genius on the left and madman on the right.

Who the hell is he?

At this time,

many students noticed professor Jeff's expression. He seemed so calm and calm that he didn't feel much about the genius around him, as if all this was taken for granted.

Do you know each other?

Otherwise, why did Professor Jeff meet with no expression?

"Alas

"I feel... This figure is very familiar, is it my illusion?" A black classmate said, "I seem to have seen this figure not long ago, really... I have, but I just can't remember where I saw it."

"That's what you say." The white people on the edge were speechless at the same time.

"No!"

"I did see it. I swear to God." "And in the near future," the black student said seriously

In fact,

the white students on the edge are not like this, but I'm sorry... I can't remember who he is. If he is a famous person, he must know who he is. Unfortunately, he is not a celebrity.

Xu mang is still struggling to calculate, but is about to enter the final stage.

One minute later,

Xu mang got a very long formula and a complex conjugate equation. However, the self consistent equation at this time is an equation satisfied by a single electron wave function. Although it is a little simpler than the wave equation, it is, after all, a nonlinear differential integral system.

It can be simpler!

Xu began to approximate gradually, using an appropriate central field to replace the previous long formula. After calculating the single electron wave function, he brought the wave function to the central field, calculated its value, compared with the original value, and then adjusted the central force field.This process is... A little time-consuming.

Because it must be within a required accuracy range, the central force field measured must be consistent with the calculated central force field.

When Xu mang is trying to reach a consensus,

the students gradually wake up from the shock. With the answer gradually approaching, the whole process becomes more and more clear. At this time, the students really realize the horror of Xu mang.

"..."

"..."

"..."

"..."

can this be calculated?

How is this done?

Five minutes later,

Xu finished all the calculations and proved its physical significance in fine-tuning the central force field.

"Cough!"

"Note that... This process does not take into account the antisymmetric requirement of electron exchange." Xu mang came to the first blackboard, pointed to the product of electron wave functions, and said seriously: "if we consider the requirement of electron exchange antisymmetry, we should show the quantum state of each electron here."

"Of course..."

"because of the limited time, I will not prove the electron exchange antisymmetry in the wave function of multi electron system any more." Xu mang said with a smile: "you will come into contact with it in the future."

This...

this...

who is this guy?

"Professor Xu!"

"Thank you for your live teaching." Professor Jeff said to Xu with a blank face and a smile: "I can't believe I can catch you alive here."

“？？？”

“？？？”

“？？？”

What?

Professor Xu?

He... He's a professor?

I don't think so. Is he more like a student?

At this time,

Xu mang was also frightened on his face, which was actually recognized. What about the eastern and western face blindness? Why doesn't it work all of a sudden?

"I remember it!" A girl stood up excitedly, pointed to Xu Mang and yelled: "Professor Xu Mang, the authority in the field of superconductivity and black hole, one of the judges of the future science award, and an outstanding pioneer of physics."

As a result,

there was an uproar on the scene, and everyone knew who the young man was.

No wonder so familiar, before the Internet is full of his reports!

Among them,

the most exciting one is that the girl named Casey got the instruction of Professor Xu. At this time, she took a look at the equation in her Notepad, and was more determined to go on the path of no return to physics.

After all,

is Professor Xu too narcissistic?

At this time,

at this time,

most people are still silent in surprise. After all, it is very difficult to see Xu mang. The most important reason is that he is a foreigner. Unless he goes to China on the west coast of the Pacific Ocean to see him, there are no special circumstances and basically can't see him.

Pa Pa Pa Pa Pa!

There was applause and a look of respect.

Soon,

the noisy classroom returned to calm.

"Professor Xu."

"There's an hour left." Professor Jeff said with a smile, "can you tell us what you think of the future and what you're up to now?"

The future view,

the latest trend...

after thinking about it for a while, Xu mang said seriously: "learn physics well and go to the universe!"

"It's over?"

"It's over!"

All of a sudden,

the students present were depressed. Is this too perfunctory?

"Cough!"

"Professor Xu... Why, let's talk about your latest trends?" Professor Jeff asked, "you bought MIT's laser interferometer for 100 million yuan. Are you planning to enter the field of gravitational wave detection?"

"Yes

"At present, the construction of the laboratory has been completed, and I have received letters of appeal from all over the world, hoping to participate in this exploration project. Now the personnel have been basically determined. It is estimated that the gravitational wave detection will be officially launched in April." Xu said.

"Are you confident that you will be the first to detect it?"

This question...

has a little meaning of luring into the pit.

But Xu mang doesn't matter. There are only two sets of equipment in the world, which are bought by his father-in-law. What competition can others take? I'm two years ahead of them. Why can't you do it?

"Of course

"For the Nobel Prize in physics." Xu mang said with a smile.

Although a bit arrogant, many people here are willing to believe that Xu mang can win the Nobel Prize in physics. Some of Professor Xu's research findings are fully qualified to win the international prize, but so far, he has not won any awards. This is indeed a pity.How to say...

many international awards owe Professor Xu a trophy.

"In fact, I'm just like a person..."

at this time,

a song of "poultry you are too beautiful" sounded, and Xu mang glanced at Xiaoman's call again and hung her up in silence.

"What..."

"sorry, I have to go." Xu mang awkwardly and politely said: "come back next time when you are free, Professor... Goodbye!"

"Well!"

Of course, Xu mang came to the door and suddenly stopped. He turned to the students and said, "goodbye, students."

For a moment,

Xu Mang's figure disappeared in the field of vision.

The students here knew that the next time they met, it might be at the Nobel Prize in physics.

...

"asshole!"

"Where the hell are you?"

At this time,

at this time,

Yang Xiaoman finally got through Xu Mang's phone call, and he growled and complained to him: "I called you so many times, but you didn't answer any of them..."

XU mang said with a smile: "what? At that time, the situation was quite special, there were all people around... I can only hang you up, this is not... Just escaped."

Yang Xiaoman urged: "come to the comprehensive office of mathematics major immediately, and ask about the way if you don't know the way."

"Oh..."

after hanging up the phone,

Yang Xiaoman looked up at his cousin and said with a smile, "he's here."

Many of the professors present did not understand each other because they spoke Chinese.

"Professor mu?"

"What is the situation now?" A professor asked in a hurry, "is Professor Xu mang here?"

Xiaoman's cousin looked at all the people present and nodded helplessly and said, "he... He will be here soon. Don't worry."
