Xu Mang was still struggling to calculate, but he was about to enter the final stage.
1 minutes later,
Xu Mang got a very long formula and a complex conjugate equation, but the self-consistent equation at this time is an equation satisfied by the wave function of a single electron. Although it is a little simpler than the wave equation, it is nonlinear after all. System of Differential Integral Equations.
Can be more simple!
Xu Mang began to approximate step by step, using an appropriate central field to replace the previous long calculation formula, after finding out the single-electron wave function, bring the obtained wave function into the central field, and calculate its value, which is the same as the original and then fine-tune the central force field.
This process is... slightly time consuming.
Because it must be within a required accuracy range, the center force field obtained after trial must be consistent with the center force field obtained after calculation.
When Xu Mang was trying to reach a consensus,
The students gradually woke up from the shock. As the answer gradually approached, the whole process became clearer and clearer. Only then did the students truly realize Xu Mang's horror.
"..."
"..."
"..."
How could this work out?
How exactly is this done?
5 minutes later,
Xu Mang finished all the calculations. In the fine-tuning of the central force field, its physical significance has been proved.
"Cough cough!"
"Pay attention... this process does not take into account the exchange antisymmetry requirements of electrons." Xu Mang came to the first blackboard, pointed to the product of the wave functions of each electron, and said seriously: "If you consider the electron's In exchange for the antisymmetric requirement, then the quantum state of each electron should be represented here."
"certainly..."
"Due to limited time, I will no longer prove the exchange antisymmetry of electrons in the wave function of the multi-electron system." 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 on-site teaching." Professor Jeff said to Xu Mang with a smile on his face, "I never thought I could capture you alive here."
"???"
"???"
"???"
what?
Professor Xu?
He... he's a professor?
I don't think so at all, he is more like a student, right?
at this time,
Xu Mang also had a look of horror on his face. He was recognized unexpectedly. What happened to the East and West blindness?Why doesn't it work all of a sudden?
"I remember!" A girl stood up excitedly, pointed at Xu Mang and shouted: "Professor Xu Mang, an authority in the field of superconductivity and black holes, one of the judges of the Future Science Award, an outstanding frontier leader in physics By."
words fell,
There was an uproar on the scene, and everyone knew who this young man was.
No wonder he is so familiar, the Internet was full of his reports before!
among them,
The most exciting thing was that girl named Casey, who actually got the guidance of Professor Xu. At this time, she glanced at the equation in her notepad, and made up her mind to go down this path of no return in physics. .
anyway,
Isn't Professor Xu too narcissistic?
And got married...
at this time,
Most people were still silent in surprise. After all, it was not easy to meet Xu Mang. The most important reason was that he was a foreigner. Unless he went to Huaguo on the west coast of the Pacific Ocean to meet him, there were no special circumstances. Basically invisible.
clap clap clap!
There was applause, and there was a trace of respect in the eyes.
quickly,
The noisy classroom returned to calm.
"Professor Xu."
"There is still an hour." Professor Jeff smiled, "Could you briefly explain your views on the future and your latest trends?"
future view,
Latest trends...
Xu Mang thought for a while, and said seriously, "Learn physics well and go to the universe!"
"ended?"
"ended!"
suddenly,
The students present looked depressed, isn't this too perfunctory?
"Cough cough!"
"Professor Xu...then why, let's talk about your latest trends?" Professor Jeff asked: "Before you bought MIT's laser interferometer at a price of [-] million, this is to enter the field of gravitational wave detection ?"
