Recently, there was an uproar in the mathematics world.
First was Sir Atiyah and the Riemann’s conjecture, then it was Schultz and Shinichi Mochizuki.
Recently, Peter Schultz and Jakob Stix recently co-wrote a thesis regarding Shinichi Mochizuki’s 1.5 inequation proof. They also said that Shinichi Mochizuki’s proof process required a lot of corrections.
Of course, in Mochizuki’s opinion, Schultz didn’t discover any problems.
As for the reason, he would explain it in a thesis.
Compared to Sir Atiyah’s abysmal thesis, this fight was obviously a lot more popular among the mathematics community.
After all, it was rumored that there were fewer than 20 people in the world that could understand Mochizuki’s 500-page book that caused quite a bit of controversy in 2012.
One was the founder of the “anabelian geometry”, “Teichmuller theorem”, and the disciple of Mr. Faltings while the other was the founder of the “PS theory”, and the winner of the Fields Medal.
The confrontation between the two seemed epic, and it dazzled the outsiders who were watching the fight.
Unfortunately, compared to number theory, Lu Zhou wasn’t well versed in algebraic geometry, much less the extremely unpopular anabelian geometry.
The abc conjecture wasn’t something Lu Zhou wanted to pay a large amount of attention to. He set notifications on for the development in this topic and left it aside. He put all his energy into his superconducting materials research.
Although the mathematical model was complete, he still needed to be at the laboratory.
Any theorems that were based on calculations were open to being questioned. Computational materials could only guide experiments, it wouldn’t determine the final experiment results.
Lu Zhou didn’t stay in the laboratory just to produce results as soon as possible. It was also to perfect his own theories through the knowledge gained from experiments.
Time quickly flew by; it was already the end of October.
A quiet celebration was heard in the scanning electron microscope room at the Frick Chemistry Laboratory.
Why was it quiet?
Because the instrument and samples at the laboratory were too “fragile”, plus their experiments were full of metaphysics where even the tiniest vibrations could affect the final experiment results.
“It’s a N-shaped doping! We did it!”
Connie clenched his fists as he excitedly looked at the image in the scanning electron microscope. He recorded the data and said, “I knew it. As long as you participate in the research project, anything is possible!”
This sudden compliment was as unexpected as the experiment result. Lu Zhou was almost embarrassed by it. He said, “That’s an exaggeration, I only provided a mathematical model.”
Professor Chirik was standing next to them, just as cheerful. However, he had been around a lot more than Connie.
Therefore, he smiled as he joked, “No need to be humble, your mathematical model was undoubtedly useful. If we used traditional methods to find this sample, we’d be lucky to produce any in-progress results by the end of the year.”
Compared to the Jinling Institute of Computational Materials and Sarrot Laboratory, their focus was mainly on theory and finding the electronic band structure close to zero dispersion…
According to Lu Zhou’s mathematical model, the positions of the two energy bands were at the negative and positive doping ends of the graphene Dirac point. This was proven by the experiment.
What was the reason for all this?
There were many reasons.
Finding the zero-dispersion energy band meant finding the Mott insulator.
When they applied a small voltage to the two-dimensional structure material and added a certain amount of electrons to the Mott insulator, a single electron combined with other electrons in the graphene would allow them to pass through a place that couldn’t previously be accessed.
Throughout this entire process, Lu Zhou and the team had been measuring the resistance of the material while also reducing the temperature of the material. They soon discovered that whenever the temperature dropped to 101K, the resistance rate of decrease suddenly reached a peak, and the value of the resistance also approached zero.
Obviously, this was what they were looking for.
Sometimes theory and application research didn’t form a contradiction, especially in the field of materials science.
Of course, underlying these simple research were many profound theoretical problems; problems that Lu Zhou didn’t even know how to explain.
For example, how could he explain the forbidden superlattice bandwidth near 1.1 degrees, or what kind of parameter should be used to describe the Mott insulator formed at this angle…
Maybe someone in the future would dive into these theoretical problems, or maybe their research partners would be interested in this type of follow-up work.
In short, when they changed the concentration of charge carriers by using N-doping, they also adjusted the superimposition angle of the two-dimensional materials. Finally, they found a “half-filling” structure by using the new angle.
When the temperature reached 101k, as they imagined, the material went through a superconductivity transition.
Although 101K wasn’t a high temperature, relatively speaking, this was undoubtedly an amazing achievement.
Excited, Connie looked at Lu Zhou and asked, “Professor, what should we name this new material?”
Lu Zhou said, “… Are you guys sure you want me to name it?”
Honestly, Lu Zhou wasn’t good at coming up with names.
He was quite self-aware about this.
However, these two obviously didn’t know that.
It wasn’t just Connie, even Professor Chirik smiled and said, “Of course, this should be done by you.”
Lu Zhou didn’t want to refuse their kind gesture. He thought about it seriously for a moment before he said, “Okay then… Let’s call it SG-1.”
SG-1 stood for Superconductivity Graphene 1. Although they could name it by a preparation method or a compound type, functional naming was easier to distinguish.
After all, there were countless ways in which two-dimensional materials could be superimposed on each other, not to mention the complex chemical processing methods; all of them produced a different N-doping graphene material…
Lu Zhou wasn’t confident at first, but he was quite satisfied with this name.
Of course, being satisfied alone wasn’t enough; he had to seek the opinions of his two partners.
“What do you guys think about this name?”
Connie: …
Chirik: …
When the two suddenly became silent, Lu Zhou hesitated slightly.
“… What?”
Chirik and Connie looked at each other and made a helpless expression.
Connie: “Nothing, SG-1 it is… It’s just such an exciting discovery, I thought you’d come up with a cooler name.”
Now that I think about it, this is Lu Zhou’s style.
Modified PDMS and HCS-2…
I knew I shouldn’t have let him be the one to name the material.
Lu Zhou: “…”
