Chapter 187 I Want to Be Your First Leg Pendant
Over the course of several weeks, Xu You conducted many sets of experiments on non-Fermi liquids.
The experiment was generally successful, and Xu You also came to some new conclusions.
However, there is still some distance to go before we can fully understand the mechanism of high-temperature superconductivity.
Moreover, Xu You feels that some parts still need to be explained in conjunction with quantum spin liquid.
After confirming the experimental arrangements, Xu You came to the quantum physics laboratory.
Although Xu You hasn't been here for a long time, he is still very familiar with it.
Wang Xiangwu was not in the laboratory, but Zhao Weijia was busy with his own experiments.
Seeing Xu You coming, Zhao Weijia was also delighted.
"Xu You, long time no see! After so many days, you finally come to the lab again."
Seeing his long-lost senior brother Zhao Weijia, Xu You was in a good mood and chatted with Zhao Weijia about recent events.
At this moment, 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 and my hair has grown back. This way, I will be more popular in the dating market."
"So, you're still on a blind date, right?"
"Haha, just like you said last time, the fruit I like really doesn't want to be picked by me. Let's take it slow."
After chatting for a while, the two began their own experiments.
The experiment conducted by Xu You was about quantum spin liquid.
When the temperature approaches 0K, the frustrated spin system neither exhibits long- range magnetic order nor breaks the lattice symmetry.
Its low-energy physical properties show fractional quantum characteristics, which is the quantum spin liquid state.
This special state is closely related to superconductivity, and is therefore one of Xu You's important research objects.
After a series of experimental operations, Xu You prepared a quantum spin liquid model with an effective spin of 1/2 based on a two-dimensional hexagonal honeycomb lattice.
Using various data in the model, Xu You calculated the Hamiltonian of his system.
Soon, half a day was over.
While Xu You was resting, Zhao Weijia came to Xu You and put his hands on his shoulders.
"Brother, what are you doing?"
"You've been doing experiments for the whole morning. You must be tired, right? Come, let me massage your shoulders."
Xu You knew that since Zhao Weijia was being so attentive to him for no reason, he must have some purpose.
"Tell me, Brother, what can I do for you?"
Zhao Weijia smiled and said:
"Haha, I still can't hide it from you. I have some problems in my project that are not easy to solve. If it is convenient for you, can you spare some time to help me take a look?"
Xu You thought that this little favor would be no problem at all.
"Well, Brother, let me take a look now. Anyway, this project of mine takes a long time, and I don't know when I can finish it."
"Okay, wait a moment, I'll show you my data."
Zhao Weijia was very happy after getting Xu You's consent.
Ever since Xu You helped me solve a difficult problem in the project.
Zhao Weijia decided that Xu You was his lucky star.
Zhao Weijia doesn't have any big wishes in this life.
Zhao Weijia would feel satisfied if she could become Xu You's first leg pendant.
Zhao Weijia moved the mouse and turned out the data of his thesis.
"Xu You, this is it. I used the single-particle spectrum function A(k, ω) to describe the experimental data measured by ARPES. And this is its relationship with the Green's function..."
Listening to Zhao Weijia's story, Xu You quickly understood Zhao Weijia's problem.
"Brother, that means you didn't get the accurate Elishberg function in the end, right?"
"Yes, there may be some problems with the intermediate method, which affects the relevant physical quantities."
"I see. I'll take a look."
Seeing Xu You reading his paper seriously, Zhao Weijia was not idle either.
Zhao Weijia took out a tea bag and put it into the teapot, then filled it with boiling water and made a pot of hot tea.
After brewing the tea, Zhao Weijia poured a cup of tea for himself and Xu You respectively.
"Xu You, this is chrysanthemum tea. It has the effect of reducing liver heat and improving eyesight. Drink it while it's hot. It won't taste good when it gets cold."
Zhao Weijia knew that this problem could not be solved in a short time.
Zhao Weijia has been studying it for more than half a month, but has not come up with any clues.
Xu You waved his hand upon hearing this:
"No hurry, wait until I solve this problem before drinking."
Zhao Weijia thought, by the time you solve this problem, the tea will have gone cold.
But when Zhao Weijia came 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 moment, Zhao Weijia suddenly remembered a familiar plot:
"Cao ordered a cup of hot wine to be poured for Guan Gong, and he drank it and then mounted his horse. Guan Gong said: "Pour the wine, I will be back soon..."
"Xu You might want to..."
Just then, Xu You put down his pen.
"Brother, I've pushed it out, please take a look."
After handing the draft paper to Zhao Weijia, Xu You could finally go and drink tea with peace of mind.
Xu You picked up the teacup and brought the tea to his mouth.
"It's so hot!" Xu You exclaimed.
These three simple words hurt Zhao Weijia's heart.
While hesitating, Zhao Weijia glanced at the results presented by Xu You.
Sure enough, this is the answer I wanted.
Next, Xu You explained his ideas to Zhao Weijia while drinking hot tea.
"Because it does not contain the original electronic dispersion of multi-body interactions, it does not depend on temperature changes. When the electron self-energy measured at two temperatures is subtracted, the parameters will be eliminated, and this expression can be obtained based on equations (2) and (3)..."
After listening to Xu You's explanation, Zhao Weijia took a long time to react and finally understood the whole derivation process.
"Xu You, you are amazing! You have helped me solve another difficult problem! This time, this project is finally going to break through the bottleneck. Xu You, come, have another cup of tea. This tea is especially good for the eyes."
Xu You's mouth was burned just now and he still feels a little bit burning.
Zhao Weijia clearly said that the tea was about to get cold, so Xu Youcai drank it in a hurry. He didn't expect it to be still so hot.
"Haha, when Hua Xiong meets Guan Gong, he will be killed instantly!"
Xu You didn't know why Zhao Weijia suddenly said this.
"Brother, wasn't Hua Xiong killed by Sun Jian in history?"
"I know, but the plot in the novel is still more interesting."
In the following days, Xu You continued his experimental life day after day.
After a few more weeks, Xu You completed the planned experiment.
"We have finally obtained enough experimental data. Next, we will start the crucial analysis work."
