The top student must be diligent.

Chapter 149 I'll go back to the lab to verify it

As Luo Mingya said, the next step is to publish the paper.
As for where the paper will be published first...

This is indeed a problem.

Since it is a paper on materials science, it would of course be best to publish it in the field of materials science.

It’s just that arxiv does not include the field of materials science, nor does it even contain any chemistry content. Generally speaking, materials science can be classified as chemistry.

Of course, there is also a chemistry preprint website, ChemRxiv, which includes papers on materials.

It's just...

Xiao Yi was too lazy to register on this preprint website.

"Forget it, let's just post it on the physics section of arxiv."

Anyway, there is not that big a difference between materials science and physics. All the previous papers related to density functional theory were published in physics journals, namely Physical Review. Its sister journal Physical Review Letters is a top journal in the field of physics.

However...as for which journal he will submit his paper to later, let's wait and see how the situation develops.

Xiao Yi didn't worry about it anymore. After organizing the paper, he submitted it directly to arxiv.

"Well, the next step is to wait for the review to pass..."

After sending out the paper, he stopped caring about it.

In the following time, he chose to continue studying the Goldbach conjecture.

"We have already studied to the extent of combining Xiao's expansion with the Yuan method."

"But... it seems to be a little bit lacking in details. What is the difference?"

As his thoughts gradually sank, he once again entered into deep thought.

……

Time passed quietly.

In an afternoon tea restaurant at Princeton University.

Manjul Bhargava was discussing a topic with another professor over a cup of coffee.

The professor's name is Ali Yazdani. He is a professor at the School of Physics at Princeton University, and he is also the director of the Princeton Center for Composite Materials.

It can be said that he is very good at using physical methods to analyze material problems and is a top expert.

"Manjuer, how long will it take us to complete our computational model?"
Ali Yazdani put down his coffee cup and asked Manjul Bhargava.

“Probably another week,” Bhargava replied.

As a Fields Medal-level mathematician, it is very common to be invited by scholars in other fields to help with data analysis.

So some time ago, Yazdani approached him and asked him to help model a material model.

Hearing that there was still a week left, Yazdani asked, "Well, this is a bit long. Is it troublesome?"

“No, not really.” Bhargava shook his head and said, “I just attended a math conference and gained a lot from it, so I devoted some time to study some math.”

"I see." Yazdani nodded to show his understanding, but he still smiled and joked: "But what other mathematics conference can you, a Fields Medal winner, gain something from?"

Bhargava said angrily: "Look at what you said. If winning the Fields Medal means you understand all mathematical knowledge, then we in the mathematics community would have proved the Riemann hypothesis 10 times."

"That report included the math genius Xiao Yi. He briefly talked about some things, which gave me a lot of inspiration."

Yazdani raised his eyebrows: "Is that the super genius who is not even 20 years old?"

"Yes." Bhargava nodded. "In addition, he also revealed at the meeting that he has been researching applied mathematics recently. It may not be long before there are results. Maybe you can pay attention to it and it may be able to bring some help to your project?"

Yazdani burst out laughing: "How is this possible! As you know, we are currently studying topological insulators, which mainly involve surface states and spin-orbit coupling effects. This is already quite cutting-edge research. He was still proving the twin prime conjecture in January. What heavyweight results can he come up with now?"

Bhargava shrugged. “That’s just talk.”

But at this moment, they suddenly heard several students discussing: "Guess what I found? I just saw GodXiao published a new paper on arxiv, and it is related to the field of physics, but it seems to involve materials."

"Really? It's not related to mathematics?"

"It should be true. I attended Zhang Yitang's report on the Landau-Siegel zero-point conjecture a few days ago, and GodXiao revealed that he would publish results on applied mathematics soon."

“Take a quick look…”

……

Listening to the students' conversation, Bhargava and Yazdani looked at each other. Uh...

It seems like it’s really a bit of a coincidence?
"Impossible, absolutely impossible." Yazdani shook his hands. He absolutely did not believe that Xiao Yi's paper could bring him any effect.

How could such a coincidence happen?

"I know you are anxious, but don't be anxious yet." Bhargava laughed and said, "Let's take a look first."

Then he took out a notebook from his bag, quickly opened arxiv, and searched for Xiao Yi's paper.

Soon, he found the paper.

"That should be it. The title of the paper is... "Calculation of Absolute Electronicity"."

Seeing the title of the paper, Bhargava raised his eyebrows: "Absolute Electron? It seems that Xiao Yi directly proposed a new computational material model. This should be a big deal for the materials science community, right?"

He looked at Yazdani again: "Hey, maybe it can really help your project, don't you really want to take a look?"

"No matter what, I don't believe it. Xiao Yi has made so many achievements in mathematics. How could he make important achievements in materials science?"

Yazdani shook his head, but his eyes still moved closer honestly.

"I just want to see what he has come up with. Maybe it will be helpful for the research of materials. Of course, if he is wrong, I will also give him some advice."

First, the summary.
【This paper proposes a computational material model called Absolute Electronicity Calculation (AEC) to achieve more accurate predictions of material properties in complex systems. The model combines multiple computational material theories including density functional theory and first-principles calculations, and introduces a new electron correlation processing method to more accurately describe the electron behavior in strongly correlated electron systems.

Through testing a series of typical materials (such as high-temperature superconductors, heavy fermion systems and topological insulators), we have verified the high accuracy and reliability of AEC in calculating electronic band structure, state density and superconducting transition temperature, etc. In particular, AEC was used to predict the properties of high-temperature superconductor YBCO, and its superconducting energy gap and transition temperature were successfully predicted, showing its advantages in dealing with strongly correlated electronic systems.

This research provides a powerful tool for theoretical studies of complex electronic structure systems and is expected to have a profound impact on the research of materials science and condensed matter physics.

After reading the summary, Bhargava showed a little surprise on his face: "Wow, it sounds like there is something to it?"

"If we can achieve accurate predictions for yttrium barium copper oxide... Ali, don't you think this is amazing?"

Yazdani frowned and said, "Let's wait and see. We haven't verified whether his model is correct yet."

Hearing his words, Bhargava smiled.

Obviously, Yazdani's words have already acknowledged from another perspective that this model may indeed have something to offer, if it can even achieve accurate predictions for YBCO as stated in the abstract.

The two stopped talking and continued watching.

Of course, when he saw that the book involved some more in-depth theories in materials science and physics, Bhargava stopped reading because he couldn’t understand it anymore.

After all, he is just a mathematician.

However, he was still quite surprised.

When did Xiao Yi acquire so much knowledge in these areas?

In addition to his research in mathematics, does he have the energy to study these?

As for Yazdani next to him, he had basically placed the laptop in front of him.

Although he said he didn't believe it, he was still watching it very seriously.

Time passed slowly.

Until finally, Yazdani raised his head with an incredible look on his face.

"This...this...this..."

“Now you believe it?” Bhargava said.

“I…” Yazdani was speechless.

After reading this paper, he was left with shock. Not to mention the mathematical techniques Xiao Yi demonstrated in the process of introducing path integrals and Markov chain Monte Carlo techniques, that part of the content... to be honest, he couldn't understand it either.

However, based on the calculation results of several complex materials that Xiao Yi cited as examples later, he felt extremely incredible. The error rates were all within 10%. Wasn't this a bit too outrageous?
Especially for high-temperature superconductors like YBCO, it is even more...

"Could this thing even be used to study the mechanism of high-temperature superconductivity?"

He couldn't help but think of it in his heart.

It can't be that the data is falsified. After all, he is a top math genius and he shouldn't do such a thing.

Finally, he stood up and said, "Whether you believe it or not... I have to go back to the lab to verify it, so I won't stay here with you for now."

"Go ahead, go ahead." Bhargava laughed, "Go and experience what a true genius is! Now you can also understand how we mathematicians feel when facing Xiao Yi."
