Chapter 197: New Methods for Searching for Superconductors
“This feeling is still very good.”
After returning to his seat, Xu You recalled what had just happened.
Being able to make other people understand your theory is also a way to gain a sense of accomplishment.
Through the narration just now, Xu You also had some new understanding of his own theory.
Qiao Sen nodded to Xu You, expressing his approval of his performance.
As a professor of condensed matter physics, Qiao Sen understood very well what Xu You had just said.
Although these contents only occupy a small part of Xu You's entire theory.
But Qiao Sen could also feel that Xu You's theory was indeed of extraordinary significance.
And in the face of so many experienced professors below, Xu You was still able to give his lectures calmly.
This kind of performance is indeed very rare.
Even Qiao Sen himself found it difficult to reach such a level.
In addition, Xu You also did a good job in controlling his posture.
Neither appear arrogant nor inferior.
It can be completely described as "neither humble nor arrogant".
Then it was time for several other professors to come forward and explain some of their academic achievements.
Some professors’ lectures are really exciting, while others are rather dull.
But Xu Youdu gained a lot of new knowledge in the process of listening.
This kind of academic exchange lasted for some time.
Everyone has a certain understanding of Xu You's theory.
Xu You's knowledge of materials science has also improved significantly.
After careful discussion, the project began to be planned.
The work that each professor was responsible for was gradually assigned.
We will explore various directions that may lead to the discovery of new high-temperature superconductors.
But Xu You was not restricted to any direction.
When it comes to finding high-temperature superconductors, Xu You has a unique idea.
After returning to his rental house, Xu You began to prepare for this idea.
Through these days of communication with experts.
Xu You further understood the properties of various materials.
In this way, Xu You can better simulate various materials through the software.
"If we can use software modeling to search for superconductors, it will definitely be a more efficient way."
Such an idea may sound a little bizarre.
But in fact, when helping Xu You synthesize new metal atom clusters.
Software modeling plays an important role.
As long as a very high degree of simulation can be achieved.
Software simulation will have great practical significance.
These days, Xu You has gained a deeper understanding of his theory of high-temperature superconductors.
This set of theories can greatly help Xu You in his software modeling work.
After reaching the academic level of informatics and a Ph.D. in informatics.
Xu You has also become more adept at software modeling work.
After a period of work.
Xu You can already do this. By inputting information such as the type of element, the number of each atom, and the way atoms are bonded together, he can predict the probability that a molecule will be superconducting.
If the probability of superconductivity of a molecule is extremely high, the superconducting critical temperature of the material can also be predicted.
Through verification, it was found that Xu You's software modeling has a relatively high overall prediction accuracy.
After that, Xu You continued to expand the amount of data, comparing the actual information of various substances with the predicted information, correcting errors, and further improving the software's prediction accuracy.
Seeing that the accuracy rate has reached over 99%, Xu You was very excited.
"Sure enough, the importance of informatics in scientific research is really huge!" Xu You exclaimed.
Xu You wished he could send Peng Jun a banner right now to express his gratitude to Peng Jun.
In this way, as long as the molecular formula and molecular structure of a molecule can be determined, superconductivity can be predicted through software without having to measure it one by one.
The discovery of superconducting materials is absolutely a revolutionary achievement.
But soon, Xu You also calmed down.
“Although the modeling program has been developed, the amount of data that needs to be verified is indeed too large.”
Now, what lies before Xu You is a permutation and combination problem.
For each simulation, Xu You needs to extract several elements from more than 100 chemical elements and determine the number of each atom, the structure between atoms and other information.
In this way, the types of substances that need to be measured are almost infinite.
Such a huge amount of data is even greater than the number of all possible chess games that can occur in Go.
Even supercomputers cannot complete all calculations within a limited time.
"No wonder high-temperature superconductors are so hard to find. If we can't determine the range of high-temperature superconductors, it will be harder than finding a needle in a haystack."
Even if room-temperature superconductors at normal pressure really exist, it is unknown when we can find them.
Thinking of this, Xu You decided to narrow down the scope of several conditions first.
"First, select several elements that are most likely to form superconductors, and limit the number of atoms of each element to within 200..."
For example, the superconductor with the highest temperature at normal pressure known so far has a strange molecular formula of Hg12Tl3Ba30Ca30Cu45O127.
Xu You roughly estimated the number of possible combinations after narrowing the range of conditions.
"The number is still too huge. Ordinary computers are definitely not able to complete the calculation. It seems that supercomputers will be needed again."
Xu You estimated that if this method was used to find new high-temperature superconductors, the cost of supercomputing electricity alone would be very high.
But in comparison, this should be the fastest way.
If one material is synthesized and measured at a time.
Not only is the preparation cost also not low.
The time consumed is also much greater.
Thinking of this, Xu You found Qiao Sen and explained his new idea to him.
"Using software simulation to predict superconductors? This is a really novel idea."
And when Qiao Sen carefully looked at Xu You's model and input some substances for verification.
It was found that the prediction accuracy of Xu You’s model is indeed very high.
“What an incredible result!”
The value of such a software model alone is difficult to estimate.
But after further communication with Xu You, Qiao Sen also realized another problem.
"Indeed, the number of all possible molecular structures is too huge. If we want to verify them one by one, there will definitely not be enough time."
"Teacher, I want to first define a rough range and select a few of the most likely elements for verification. Although the amount of data is also very large, it is still possible to complete the calculation if a supercomputer is used."
