Great Country Academician

The report meeting on the stage is still going on.

Xu Chuan explained the unified framework theory of strongly correlated electronic systems in an orderly manner. It was not until the introduction of dimensional space that the speed slowed down a bit.

This is the core of the entire framework theory, which uses the concept of dimensions to divide different materials, and then uses different mathematical theories and methods to explain the strong correlations in different dimensional areas.

"The oscillation and Weber blocking effect caused by the vortex motion of the magnetic flux can form van der Waals heterojunctions between different low-dimensional films, and their physical properties can be controlled through symmetry engineering methods such as twisting and stacking."

"Novel physical properties of the interface can also be studied by stacking films with different physical properties, such as the study of superconducting/ferromagnetic heterogeneous interfaces."

"The specific mathematical method can be started from the following: χ(q,ω)=∑kfkfk+qεkεk+q+ω."

"."

On the reporting table, Xu Chuan separated the introduction of dimensional space into a separate topic and explained it carefully.

Off the stage, many physicists in the auditorium were also staring intently at the PPT on the screen, listening to every word with their ears wide open, for fear of missing any detail.

For Xu Chuan, the mathematical methods applied in the unified framework of strongly correlated electronic systems are not very deep, but for most physicists, it is still quite difficult to fully understand these things.

Although it can be said that all top physicists understand mathematics, and many of them are even top mathematicians, they have greatly promoted the development of mathematics.

Such as Newton (calculus), Heisenberg (matrix), Descartes (Cartesian curve), Laplace (Laplace transform) and so on.

But not every physicist can take into account mathematical physics.

Just like Einstein, Maxwell, Bohr and others, although their mathematical attainments are equally different, they are still some distance from the top.

And although most of the physicists sitting here today can use mathematical tools to solve some problems encountered in research, but if you want to say that people like Witten and Xu Chuan directly won the Fields Medal, they have the ability to do so. There are very few people with top mathematical abilities.

Fortunately, before this report meeting, there was enough time for them to understand and familiarize themselves with the paper, so that they would not be left behind at the report meeting.

On the lecture stage, Xu Chuan was explaining the paper while paying attention to the reactions of the audience.

Especially the big guys in the front row, check to see if they understand your report.

For a novel theory, it is impossible for everyone to accept it at the first time.

But as long as the logic is perfect and has no flaws, it can be recognized by the top experts, it can pass peer review and journal review, it can be officially released publicly, and it can be circulated in the academic world as a theory, that is enough.

As for those who don't understand and still have doubts, honestly speaking, their opinions are not that important.

Unless they can find flaws in the paper, there is no need for reporters to respond.

After all, it is impossible for everyone and all scholars to understand truly cutting-edge theories.

If an individual raised a question and the reporter had to explain it, would the academic world still be developing?

Especially those in civil sciences, they like to join in the fun the most.

Therefore, in today's report meeting, Xu Chuan did not need to let everyone understand his paper and explanation. He only needed to ensure that most of the experts sitting in the front row could understand it.

Fortunately, judging from the reactions of the powerful audience members in the front row, Xu Chuan knew that he had already succeeded halfway.

At least, they should all have understood the unified framework of strongly correlated electronic systems.

Some people may still have some doubts and questions in their minds, but these questions should be resolved in the following question and answer session.

All that's left is to wait for peer review and journal review.

Waiting for the paper to be published, the physics world will have another unified framework theory.

Perhaps its importance is far less than the Standard Model or the Five Laws.

But in condensed matter physics, it will be the bible guiding its development.

As time went by, the report meeting began to come to an end.

As this stage began, the atmosphere in the lecture hall became obviously enthusiastic.

Sitting next to Edward Witten, Michael Kosterlitz closed his notebook and sighed softly: "As expected of a genius who won both the Nobel Prize and the Fields Medal. This set of theories , will forever shine in the history of physics."

To be honest, before coming here, he had read the papers on strongly correlated electron systems countless times. I also recorded many questions in my notebook.

Originally, he planned to resolve these questions during the question-and-answer session, but now it seems that it is no longer necessary.

During the lecture, the scholar had already answered most of his questions.

His reference to dimensional space and his application of mathematical methods are all worthy of astonishment.

On the side, Witten turned to look at him and said with a smile: "It would be great if he could leave a little more time for physics, so maybe we can see something beyond the standard model in our lifetime."

Hearing this, Michael Kosterlitz was stunned for a moment, then reacted and said with a smile: "I almost forgot that this person is most famous in academia not for his achievements in physics, but for his mathematics."

After a slight pause, he continued: "But speaking of which, you are his mentor in physics, guiding him to study physics. Isn't this what you should do?"

Hearing this, Witten shrugged and did not answer the question.

If he could do that, that would be great.

Maybe physics will advance rapidly in this way.

On the stage, Xu Chuan did not stop his explanation. He continued to turn over the papers on the PPT until finally:

".From the above formula, it is not difficult to see that for a two-variable function with antisymmetry, the complete basis is the two-variable Slater determinant."

"The strongly correlated electronic mathematics system based on dimensional space is theoretically suitable for the K/U0(1) system."

"That is, the strongly correlated electronic mathematics system born based on dimensional space should systematically adapt to most strongly correlated systems and form a unified framework!"

When the essay on the screen froze on the last page, as Xu Chuan's words fell, the auditorium also froze in this moment of silence.

Looking at the quiet crowd in the audience, Xu Chuan smiled and continued: ""

"We have known the universal theory of most materials a long time ago. Such as Newton's equations for atomic nuclei, Schrödinger's equation for electrons, and the electromagnetic interaction between atomic nuclei."

"But in more materials, although these theories have limitations and counterexamples. For a macroscopic system, it is impossible to solve these equations accurately."

"So all we can do is leave two possibilities, either do some approximations that are often very rigorous, or look at a simpler problem, which is the fundamental physics that we grasp."

"Today, the unified framework theory of strongly correlated electronic systems will fill the last big gap in condensed matter physics for us, at least in current research."

"It will go beyond the standard model of materials we have defined in the past and will lead us to find materials that are not described in traditional paradigms."

"This concludes my report, and I appreciate everyone's patience in listening."

After finishing speaking, Xu Chuan moved his steps slightly, walked out from behind the reporting table, and bowed slightly to the audience to show his gratitude.

At the same time, the huge auditorium was filled with thunderous applause.

PS: To make up for yesterday’s chapter, please vote for me. There are two more chapters today.
