Chapter 493: Forever Shining in the History of Physics

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, and only slowed down a bit until the introduction of dimensional space.

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

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

"It is also possible to stack films with different physical properties together to study the novel physical properties of the interface, such as the study of superconducting/ferromagnetic heterojunctions."

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

"."

On the report stage, Xu Chuan separated the introduction of dimensional space and explained it carefully.

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

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

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

Such as Newton (calculus), Heisenberg (matrix), Descartes (Cartesian curve), Laplace (Laplace transform), etc.

But not every physicist can take care of mathematical physics.

Just like Einstein, Maxwell, Bohr and others, although their mathematical attainments are also different, they are still a long way from the top.

And the physicists sitting here today, although most of them can use mathematical tools to solve some problems encountered in research, there are very few people like Witten and Xu Chuan who directly won the Fields Medal and have 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 fall behind in the report meeting.

On the report platform, Xu Chuan explained the paper while paying attention to the reactions of the audience below.

Especially those experts in the front row, to check whether they understood his report.

For a new theory, it is impossible to get everyone to accept it at the first time.

But as long as the logic is perfect and there are no flaws, it can be recognized by those experts at the top level, can pass peer review and journal review, and be officially published publicly, and circulated in the academic community as a theory, that is enough.

As for those who don’t understand and still have doubts, to be honest, their opinions are not that important.

Unless they can find flaws in the paper, there is no need for the reporter to stand up and respond.

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

If the reporter has to explain every question raised by an individual, will the academic community still develop?

Especially those amateur scientists, they like to join in the fun the most.

Therefore, at today's report, Xu Chuan didn't need to make everyone understand his paper and explanation. He just needed to ensure that most of the experts sitting in the front row could understand it.

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

At least, they should have understood the unified framework of the strongly correlated electron system.

Some people may still have some doubts and questions in their hearts, but the following question-and-answer session should be able to solve these problems.

The rest is to wait for peer review and journal review.

Waiting for the paper to land, the physics community 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 passed, the report began to come to an end.

With the beginning of this stage, the atmosphere in the lecture hall became obviously warm and high.

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

To be honest, before coming here, he had read the paper on the strongly correlated electron system countless times. He also recorded many questions in his notebook.

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

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

His reference to dimensional space and the application of mathematical methods are all worthy of admiration.

On the side, Witten turned his head and looked at him, and smiled: "If he could leave more time for physics, maybe we can see something beyond the standard model in our lifetime."

Hearing this, Michael Kosterlitz was slightly stunned, and then reacted, smiling and said: "I almost forgot that this person is most famous in the academic world for his achievements in mathematics rather than physics."

After a slight pause, he continued: "But speaking of it, you are his mentor in physics. Isn't it your job to guide him in studying physics?"

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

If he can do it, that's great.

In this way, physics may advance rapidly.

On the stage, Xu Chuan did not stop his explanation. The paper on the PPT continued to turn over until the end:

"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."

"And the strongly correlated electron mathematical system born based on dimensional space is theoretically suitable for the K/U0(1) system."

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

When the paper on the screen froze on the last page, as Xu Chuan's voice fell, the auditorium also froze in this silent moment.

Looking at the quiet crowd below the stage, Xu Chuan smiled and continued: ""

"Long ago, we knew the universal theory of most materials. Such as Newton's equations for atomic nuclei, Schrödinger's equations for electrons, and electromagnetic interaction particles between atomic nuclei."

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

"So there are only two possibilities left for us to do, either make some usually very strict approximations, or study a simpler problem, which is the basic physics we grasp."

"And today, the unified framework theory of strongly correlated electron 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."

"My report ends here, thank you very much for your patience."

After speaking, Xu Chuan moved his feet slightly, walked out from behind the report table, and bowed slightly to the audience below the stage to show his gratitude.

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