In a few weeks, Xu You did many experiments on non-Fermi liquids.

The experiment was generally successful, and Xu You also came to some new conclusions.

However, there is still a certain distance from a complete solution to the mechanism of high-temperature superconductivity.

Moreover, for some parts, Xu You feels that it still needs to be explained in combination with quantum spin liquid.

After confirming the arrangement of the experiment, Xu You came to the quantum physics laboratory.

Although Xu You has not been here for a long time, he is still very familiar with it.

In the laboratory, Wang Xiangwu was not there, and Zhao Weijia was busy with his experiments in the laboratory.

Seeing Xu You coming over, Zhao Weijia was also delighted.

"Xu You, long time no see! After so many days, you finally came to the lab again."

Seeing the long-lost Senior Brother Zhao Weijia, Xu You was also in a good mood, and chatted with Zhao Weijia about recent events.

At this time, Xu You suddenly noticed a change in Zhao Weijia.

"Brother, your hair volume...why does it seem to be more than before?"

"Oh, I had a hair transplant before, and my hair has grown back. This way, I will be more popular in the dating market."

"So, are you still on a blind date?"

"Haha, as you said last time, I really don't want to pick the fruit I like. Let's take it slowly."

After chatting for a while, the two started their own experiments.

Xu You's experiments are related to quantum spin liquids.

When the temperature tends to 0K, the frustrated spin system does not exhibit long-range magnetic order and does not break the lattice symmetry.

Its low-energy physical properties show fractional quantum characteristics, which is the quantum spin liquid state.

This special state is very closely related to superconductivity, so it is also one of Xu You's important research objects.

After a series of experimental operations, Xu You prepared a quantum spin liquid model based on a two-dimensional hexagonal honeycomb lattice with an effective spin of 1/2.

Using various data in the model, Xu You is calculating the Hamiltonian of his system.

Soon, half a day was over.

While Xu You was resting, Zhao Weijia came to Xu You's side and put his hands on Xu You's shoulders.

"Brother, what are you doing?"

"I've been doing experiments all morning, are you tired? Come on, senior brother will give you a massage on your shoulders."

Xu You knew that since Zhao Weijia had nothing to do to show courteousness, there must be some purpose.

"Tell me, brother, what can I do for you?"

Zhao Weijia laughed and said:

"Haha, I still can't hide it from you. There are some problems in my project, which are not easy to solve. If it's convenient for you, brother, can you find time to help me?"

Xu Youxin said that there is no problem with this little busyness.

"Well, brother, let me take a look now. Anyway, I have a long time for this project, and I don't know when I can finish it."

"Okay, wait a minute, I'll show you my data."

After getting Xu You's consent, Zhao Weijia was very happy.

Ever since Xu You helped him solve a difficult problem in the project.

Zhao Weijia decided that Xu You was his lucky star.

Zhao Weijia doesn't have much aspirations in this life.

Zhao Weijia would be satisfied if he could be Xu You's first leg pendant.

Zhao Weijia moved the mouse and turned out the data of his thesis.

"Xu You, this is here. The experimental data I measured through ARPES is described by the single-particle spectral function A (k, ω). Then this is its relationship with the Green's function..."

Listening to Zhao Weijia's narration, Xu You quickly understood Zhao Weijia's problem.

"Brother, that is to say, in the end you didn't get the exact Elishberg function, did you?"

"Yes, there may be some problems with the method in the middle, which affects the relevant physical quantities."

"Understood, I'll take a look."

Seeing that Xu You was seriously reading his thesis, Zhao Weijia was not idle.

Zhao Weijia took out a tea bag and put it in the teapot, filled it with boiling water, and made a pot of hot tea back.

After making the tea, Zhao Weijia poured a cup of tea for himself and Xu You.

"Xu You, this is chrysanthemum tea, which has the effect of reducing liver fire and improving eyesight. Drink it while it's hot, it won't taste good when it's cold."

Zhao Weijia knows that this problem cannot be solved in a short while.

Zhao Weijia has been studying it for more than half a month, but he has not come up with any clues.

Xu You heard the words but waved his hands and said:

"Don't worry, drink it after I finish solving this problem."

Zhao Weijia said heartily, by the time you finish solving this problem, the tea will be cold long ago.

But when Zhao Weijia leaned over and saw the process on Xu You's draft paper.

But he found that things were not what he thought.

Xu You has completed most of the derivation process and is about to get the final result.

At this time, Zhao Weijia suddenly remembered a familiar plot:

"Caojiao had a cup of hot wine, and got on the horse with Guan Gong. Guan Gong said: "Pour the wine, and you will come when you go..."

"Could Xu You want to..."

At this moment, Xu You put down his pen.

"Brother, I've released it, you can take a look."

Passing the draft paper to Zhao Weijia, Xu You can finally drink tea in peace.

Xu You picked up the teacup and brought the tea to his mouth.

"It's so hot!" Xu You exclaimed.

Those three simple words hurt Zhao Weijia's heart.

While hesitating, Zhao Weijia glanced at the results Xu You released.

Sure enough, it was the answer I wanted.

Next, while drinking hot tea, Xu You explained his thoughts to Zhao Weijia.

"Because it does not contain the original electron dispersion of many-body interactions, it does not depend on temperature changes. When the electron self-energies measured at two temperatures are subtracted, the parameters will be eliminated, and then according to (2) and ( 3) to get this expression..."

Listening to Xu You's explanation, Zhao Weijia reacted for a long time, and finally figured out the whole derivation process.

"Xu You, you are really amazing! Helped me solve another problem! This time, this subject is finally going to break through the bottleneck. Xu You, come, have another cup of tea, this tea is especially good for the eyes."

Just now his mouth was scalded, Xu You still felt a little burned.

Obviously Zhao Weijia said that the tea was going to be cold, so Xu Youcai drank it in a hurry, but he didn't expect it to be so hot.

"Haha, when Hua Xiong meets Guan Gong, he will be instantly killed!"

Xu You didn't know why, but Zhao Weijia suddenly said such a sentence.

"Brother, wasn't Hua Xiong killed by Sun Jian in history?"

"I know, but the plot in the novel is still good."

In the days that followed, Xu You continued his experimental life day after day.

In another few weeks, Xu You completed the planned experiment.

"Finally enough experimental data has been obtained. The next step is the key analysis work."
