Recently, the mathematics community had been unexpectedly restless.
First, it was Sir Atiyah and the Riemann conjecture, then it was Schulz and Shinichi Mochizuki.
Not long ago, Peter Schulz and Jacob Styx jointly published a paper arguing that there were problems with the proof of inequality (1.5) in Shinichi Mochizuki's paper and that small fixes could not save the entire proof process.
Of course, from Mochizuki's point of view, the mistakes pointed out by Schulz were not a problem at all.
As for why, he would write a paper to explain it.
Compared to Sir Atiyah's paper that was not even a mistake, this controversy was obviously more topical in the mathematics community.
After all, the 500-page paper that was said to be understood by no more than 20 people in the world had caused a considerable degree of controversy as early as 2012.
On one side was the founder of "Anabelian geometry" and "interuniverse theory", as well as Faltings' disciple. On the other side was the founder of the "PS theory" and the new Fields Medal winner. The battle between the two was like a fight between gods, and it was dazzling to the onlookers.
Unfortunately, compared to number theory, algebraic geometry was not Lu Zhou's strength, let alone the unpopular "Anabelian geometry".
The ABC conjecture was not the direction that Lu Zhou was concerned about. After he set a tab on the progress of this matter, he did not pay attention to the specific situation anymore. Instead, he focused all his energy on the research of superconducting materials.
Although the mathematical model had been completed, this did not mean that he did not need to appear in the laboratory.
Any conclusions based on calculations were debatable. What computational materials could do was only to guide the experiment, not to determine the results of the experiment.
Not only to produce results as soon as possible, but also to use the experience gained from the experiment to perfect his own theory. Regardless of the reason, Lu Zhou could not leave the laboratory.
Time passed by day by day, and it was soon the end of October.
In the scanning electron microscope room of the Frick chemistry laboratory, there was a small cheer.
As for why it was quiet.
Because the instruments here and the samples they observed were too "fragile", and the experiments they carried out were full of metaphysics, so a slightly strong vibration might affect the final experimental results.
"It's N-type doping. We succeeded, Professor!"
Connie clenched his fists and excitedly looked at the image captured by the scanning electron microscope on the screen. He saved the data and said with joy, "I knew that as long as you join my research project, the problems we face will not be a problem at all!"
This sudden flattery caught Lu Zhou off guard. He coughed and said, "You're exaggerating, I just provided a mathematical model."
Professor Chirik, who was standing next to him, was also overjoyed. However, compared to Connie, he had seen a lot of things.
"Don't be humble, your mathematical model has undoubtedly come in handy. If we used the traditional method to find this sample, we would be thankful if we could produce in-progress results before the end of the year."
Compared to the Jinling Institute of Computational Materials and Sarrot's laboratory, their work was mainly focused on theory, which was to find the two energy bands with close to zero dispersion …
According to Lu Zhou's mathematical model, the positions of these two energy bands were finally determined to be on the negative and positive doping of the graphene Dirac point.
What was the use of this?
It was very useful.
Finding the zero-dispersion energy band was equivalent to finding the Mott insulator they were looking for.
When they applied a small gate voltage on this two-dimensional structural material, adding a certain amount of electrons to the Mott insulator, a single electron would combine with other electrons in the graphene, allowing them to flow through places they couldn't before.
Throughout this process, Lu Zhou and the others continued to reduce the temperature of the material while continuing to measure the resistance of the material. Soon after, they discovered that when the temperature dropped to 101K, the resistance reached a sudden peak, and the value of the resistance rapidly approached zero.
It was obvious that this was what they were looking for.
Lu Zhou had to admit that sometimes theoretical and applied research did not conflict, especially in the field of materials science.
Of course, in addition to this easy-to-understand research, there was also a lot of more esoteric theoretical work. There were also many problems that even Lu Zhou didn't know how to explain.
For example, how to explain the bandgap width of the superlattice near 1.1 °. For example, what kind of order parameter should be used to describe the Mott insulator formed at this angle …
Maybe someone would complete this more in-depth theoretical work in the future, or maybe their partners would be interested in completing this follow-up work.
In short, they used the N-doping method to change the carrier concentration of the material and adjusted the overlap angle of the modified two-dimensional material. Finally, they found the "half-filled" structure from a new angle.
When the temperature reached 101K, this new material, as they had imagined, underwent a superconducting transformation.
Even though 101K wasn't that high, there was no doubt that this was an amazing result.
Connie looked at Lu Zhou excitedly and said, "Professor, how should we name the new material?"
Lu Zhou had a strange expression on his face as he said, "Are you sure you want me to name it?"
Honestly speaking, he wasn't good at naming things.
Regarding this, he was quite self-aware.
However, these two obviously didn't understand him.
It wasn't just Connie, even Professor Chirik smiled and said, "Of course, you should be the one to do this."
Lu Zhou smiled awkwardly and thought for a moment before he spoke.
"If that's the case … Then let's call it SG-1."
SG was the abbreviation for superconducting-graphene. Even though it could be named after the preparation method or the type of compound, it was easier to name it based on function.
After all, considering the way two-dimensional materials were stacked and the complex chemical processing methods, there were too many graphene materials that could be classified as N-type doped …
Even though Lu Zhou wasn't confident in the beginning, he was quite satisfied with the name.
Of course, it wasn't enough for him to be satisfied. He had to ask the other two partners for their opinions.
"What do you guys think of this name?"
Connie: "…"
Chirik: "…"
Seeing how the two suddenly stopped talking, Lu Zhou hesitated for a second.
"… What?"
Connie and Professor Chirik looked at each other and made a helpless expression at Lu Zhou.
"Nothing, SG-1 it is … It's just that this is such an exciting discovery, I thought you would think of a cooler name."
Now that I think about it, this guy has always been like this.
From modified PDMS to HCS-2 …
If I knew this would happen, I wouldn't have given him the chance to come up with a name.
