Chapter 839: Blindness

Although the magnetic polariton electromagnetic shield generator has been successfully tested.

But it is still a long way from the plasma electromagnetic deflection shield technology.

However, the interim results have already had certain application value.

After taking a group of people back to his office, as soon as he sat down, Academician Wang Yong couldn't wait to pull Xu Chuan and asked: "If it's convenient, can you tell me in detail about this magnetic polariton electromagnetic shield generator?"

"Regarding the generation and stable control of the magnetic polariton field, how did you do it?"

Xu Chuan smiled and simply replied: "Unified framework theory of strongly correlated electron system!"

Hearing these four words, Academician Wang Yong was obviously stunned, frowned and thought hard for a long time, and then said uncertainly: "I have read the theory of strongly correlated electron system, but does it have such a theoretical point?"

Academician Wang Enge also cast a puzzled look on the side.

They must have read the top papers in the physics community, such as the unified framework theory of strongly correlated electron system.

Not only have they read it, but they must have read and studied it more than once.

But they are sure that the papers they read did not include theories on how to verify and create magnetic monopoles and magnetic polarization fields. Could there be another version?

Xu Chuan smiled and simply answered the question: "Quantum spin!"

There is no other version, but the unified framework theory of strongly correlated electron systems is not so easy to be fully understood by people, even if the object is an academician in the field of physics, even if this theory has been around for several years.

Just like Einstein's gravitational field equations in general relativity, if the energy-momentum tensor is considered, its mathematical solution is still a very difficult problem.

Even Einstein himself could only derive multiple predictions by approximate methods.

For example, in 1917, Einstein applied the gravitational field equations to the entire universe, creating the field of cosmological applications of relativity.

Although Friedmann and Lemaître later obtained the solution of the expanding universe from the gravitational field equation, and Hubble observed the expansion of the universe, making this achievement the biggest mistake that Ai Lao thought he had made.

But this does not affect the importance of the gravitational field equation at all.

In addition to the cosmological application of relativity, general relativity also predicted and verified the precession of Mercury, gravitational bending of light, explained the expansion of the universe, discovered black holes, predicted gravitational waves, and so on.

To this day, the physics community is still constantly studying this paper, which can be called the greatest paper of the 20th century, and from time to time successfully verifies its predictions.

If general relativity is a masterpiece about gravity, then the unified framework theory of strongly correlated electron systems is the core theory of condensed matter physics.

Pulling out a blackboard from the corner, Xu Chuan picked up the marker in the pen holder, wrote a few lines of formulas on the blackboard, and then continued.

".Assume that the quantum state ψ can obtain another state φ after the operation of the operator L."

"In condensed matter physics, the behavior of the electronic system can usually be regarded as a gas (free electron gas). The "electron" here can be a quasiparticle."

"Such as the conduction band electrons in the crystal, or the single particle excitations of other interacting systems-that is, it is originally a liquid, but it can still be regarded as a gas through a simple approximation.

"Therefore, when the interaction is very small, it can be approximated by free electrons; when the interaction is very large, a Mott insulator will be formed, and the freedom of the electron or quasiparticle movement will be frozen, leaving only the freedom of spin. At this time, a large degree of freedom can be expanded to obtain an effective spin model."

Staring at the formula on the whiteboard for a long time, Academician Wang Enge frowned and said:

"Is this the inference of the unified framework theory of strongly correlated electron systems in terms of quantum spin? "

Although he is not a math researcher, he is mainly engaged in condensed matter physics research. Naturally, he has read the unified framework theory of strongly correlated electronic systems countless times.

But for the derivation of electronic systems, or quasiparticle systems, he never thought that it could be developed in this way.

Looking at Academician Wang Enge who was lost in thought, Xu Chuan nodded slightly and smiled: "That's right."

On the surface, the improvement of the magnetic polariton electromagnetic shield generator is because the Zeeman splitting has been solved and the cyclotron resonance frequency of the magnetic polaritons in the parabolic quantum dots has been improved.

But in fact, the core reason is the magnetic oscillator lattice excitation device manufactured based on the unified framework theory of strongly correlated electronic systems.

Without this, even if he knew that the magnetic monopole was a quasiparticle, he would not be able to excite it and form a magnetic polariton electromagnetic field.

Just when Academician Wang Enge was still thinking, Gao Hongming on the side couldn't wait to ask: "Can this magnetic field shield be installed on equipment such as aircraft carriers and space shuttles?"

Xu Chuan thought for a while and said: "If you want to ask about the application of comprehensive defense, I'm afraid it's not possible for the time being. "

"Although the magnetic polariton electromagnetic field is pretty good from the current laboratory test data. However, for high-power microwaves and electromagnetic attack protection, it is not the magnetic polariton electromagnetic field that is effective, but the plasma wall. "

"But the plasma wall technology is still under research. You can't just put a layer of plasma glow plate on the outside of the aircraft carrier. "

Gao Hongming quickly asked: "If the comprehensive one is not possible, what about the local one? For example, it should be feasible to deploy such a system in a certain important area?"

Xu Chuan thought for a while and said: "From the current situation, there should be no big problem."

"But."

After a slight pause, he continued: "But when the magnetic polariton electromagnetic field is in operation, it will not only intercept external electromagnetic attacks, but also internal communications."

"In short, it is a comprehensive electromagnetic shielding, regardless of friend or foe. This cannot be solved for the time being."

Hearing this, Gao Hongming frowned. This is indeed a difficult problem.

The shielding method that does not distinguish between friend and foe is indeed a very troublesome thing for electronic equipment.

Academician Wang Yong, who was standing by, smiled and said, "This is easy to solve."

Hearing this, everyone in the office looked over, and Gao Hongming asked excitedly, "Academician Wang, do you have a solution?"

"Ah~"

Academician Wang Yong shook his head and smiled and said, "You are in a misunderstanding. If it is comprehensive protection, this problem is indeed difficult to solve."

"But local protection is only local. If the wireless electromagnetic signal is blocked, it is entirely possible to transmit the information of the protected area through wired means and transmit and transfer it in other unprotected areas."

Hearing this answer, Xu Chuan was slightly stunned.

This is really a blind spot.

The wireless electromagnetic signal is intercepted, and they can transmit the signal of the protected area through a special data cable.

Of course, this method is limited to local protection.

If it is a comprehensive defense, this method is useless. After all, they can't pull a network cable to an aircraft carrier or a space shuttle.

So this solution is only temporary, and the best way is to solve the problem of wireless communication.

After all, the original purpose of this technology project was to apply it to the space shuttle so that it can cope with various cosmic rays, fine dust, etc. that it will encounter when sailing in space.

And wireless communication is too important for space navigation.

Hearing this method, Gao Hongming's eyes lit up, took a deep breath, stood up, looked at the academicians in the room and spoke solemnly.

"Thank you for your hard work, academicians. On behalf of the country, I would like to say thank you."

The importance of plasma electromagnetic deflection shield technology can directly change the form of future wars.

Whether it is the purpose of its own development, in order to protect spacecraft from the influence of cosmic radiation and dust in space, it provides important security guarantees for future lunar and Mars exploration missions;

or it is used to protect military equipment, important military facilities and national key infrastructure from the threat of "invisible killers" such as electromagnetic pulse weapons, it is crucial.

Xu Chuan smiled indifferently and said, "Don't be so polite."

Although he is not very interested in the research and development of equipment in the military industry, he is still very happy to see if his research can contribute to the national defense cause.

After all, only when the motherland is strong can we have more say.

Whether it is the miniaturization of controlled nuclear fusion technology or plasma electromagnetic deflection shield, etc., although they can be used for civilian purposes, to be honest, these technologies are more inclined to military purposes.

Of course, for him, he is generally only responsible for theoretical and technical research and development.

As for how to apply these technologies to equipment such as aircraft carriers or space shuttles, that is the task of the Military Equipment Department.

In addition, there is another point that the patents and intellectual property rights related to these technologies are in the hands of Xinghai Research Institute, that is, in his hands.

Although the profits from the military are far less than the profits brought by controlled nuclear fusion, for the institute, this is already a considerable income.

Although the purpose of studying these technologies is not to make money.

Gao Hongming looked at Xu Chuan and said sincerely: "Academician Xu, I'll leave the research and development of plasma and electromagnetic deflection shield technology to you."

"If you need any help, please let me know."

Xu Chuan smiled and nodded, saying: "Yes."

The breakthrough in magnetic polaritons and electromagnetic field technology almost made Wang Yong and Wang Enping, two academicians who came all the way here, forget their purpose and leave with Gao Hongming.

Fortunately, before leaving, they remembered the mathematical problems related to electromagnetic railguns and stayed.

As for Gao Hongming, although he came here to promote the research and development of electromagnetic railgun-related technologies, the breakthrough in electromagnetic shield and magnetic polaritons forced him to leave early.

This kind of important news related to the fate of the country must be kept strictly confidential, and the fewer people who know it, the better.

Therefore, he can only go to Beijing to report this matter to the leaders in person.

At the same time, in Xinghai Research Institute, Xu Chuan summoned the researchers of the magnetic polaritons and electromagnetic shield technology project team to the conference room and held a brief temporary meeting.

". First of all, congratulations on the breakthrough in magnetopolariton and electromagnetic shield technology. Thank you for your hard work during this period."

"However, the magnetopolariton and electromagnetic shield technology has been completed, but the related paper theory may not be made public in the short term."

"After all, it involves national security and is not suitable for public publicity, including commendation conferences, which may not be held."

In the conference room, Li Kaichang, who was responsible for the research and development of magnetic polaritons and electromagnetic shield technology, smiled and said, "Nothing, the overall situation is more important, and papers and such are not important."

On the side, several other researchers also nodded and expressed their understanding.

When they were invited to participate in this project, they had considered this situation after the project was completed.

After all, the importance of plasma and electromagnetic deflection shield technology is the focus of confidentiality for any country.

Although it is a pity that this honor cannot be written on the resume, being able to participate in such a historic research is itself a matter of pride for a lifetime.

Xu Chuan's eyes fell on the research team headed by Li Kaichang. Looking at this group of middle-aged men, he smiled and said:

"Although honors and other things may not be available in the short term, there will definitely be no shortage of related rewards, whether it is bonuses, wages, or other things, there will be, everyone can rest assured."

Hearing this, several key researchers in the conference room also smiled.

Although everyone has made relevant preparations, researchers are also human beings, with families and lives. They are naturally happy to get higher salaries and bonuses.

After a slight pause, Xu Chuan continued: "In addition, although the research and development of magnetic polaritons and electromagnetic shield technology has come to an end, the plasma and electromagnetic deflection shield technology is still in progress."

"So I will give you two choices about your future."

"One is to continue to participate in the research and development of plasma and electromagnetic deflection shield technology and cooperate with the work of researcher Zhang Ming."

"The other is to return to the original position, continue research work or take a break for a while, or prepare to apply for new projects."

"The Institute will not force you to make this choice. It's up to you. If you want to stay and continue to participate in the research and development of plasma and electromagnetic deflection shield technology, you can, and if you want to take a break for a while, it's no problem."

Before he finished speaking, Li Kaichang raised his hand first and said without any hesitation: "I choose to participate in the research and development of plasma walls."

For him, who has already participated in the research and development of magnetic polaritons and electromagnetic shield technology, it would be a pity if he did not continue to participate in the research and development of plasma and electromagnetic deflection shield technology.

This kind of technology that you can only encounter once in a lifetime, if you miss it, it would be a pity.

With Li Kaichang taking the lead, several other core researchers also raised their hands and expressed their desire to stay and continue to participate in the research and development of plasma electromagnetic deflection shield technology.

Xu Chuan smiled, and was not surprised by these people's choices.

"In this case, I will notify researcher Luo Ming to integrate team resources as soon as possible, and hope to complete the research and development of plasma electromagnetic deflection shield technology as soon as possible."

As he said, he looked at the only researcher in the conference room who was not from Xinghai Research Institute, Academician Ming Chengbi.

The old academician of the Naval Equipment Department raised his eyebrows and said, "Why, the research and development has not been completed yet, and you are going to drive me away?"

Xu Chuan smiled and said, "Since Academician Ming has made a choice, let's go with Li Kaichang and others. I am relieved to have you in charge."

He knew that Mr. Ming would not leave before the plasma electromagnetic deflection shield technology was fully developed.

This is his mission, and it is also the mission he has always taken the initiative to shoulder.
