Chapter 776: Breakthrough of the magnetic polaron electromagnetic shield!
In the large-scale SQUID superconducting quantum interference magnetometer laboratory, the first test of the magnetic polariton electromagnetic shield generator was officially launched.
Huge power sources are continuously fed into various devices through lines.
In the core experimental cabin, the magnetic polaron electromagnetic shield generator started operating, and the computer connected to the magnetometer was already continuously collecting magnetic field information and data.
In front of the computer screen, Xu Chuan's eyes fell on the curve that kept jumping, with a thoughtful look in his eyes.
Although magnetic wires, magnetic polarons, and magnetic particles cannot be seen in experiments on magnetic fields, this does not hinder anything.
Because some things do not need to be seen intuitively, intuitive data is more reliable than anything else.
It has to be said that scientific research depends largely on the advancement of equipment.
Some details and data that were not observed at the Xinghai Research Institute were exposed in the large-scale SQUID superconducting quantum interference magnetometer laboratory at the Shenzhou Branch.
Standing next to Xu Chuan, Li Kaichang, who is in charge of the magnetic polaron electromagnetic field project, looked at the data on the screen, frowned and said: "The magnetic lines are too disordered, resulting in a low guidance rate of the magnetic polaron field. This problem feels
Trouble."
Xu Chuan nodded and said: "The carriers in the solid generate an electric field that polarizes the surrounding medium. This induced polarization is accompanied by the movement of the carriers."
"The size and energy of the complex of carriers plus induced polarization in the solid are determined by the electron interaction. In other words, we need to first calculate the relationship between the internal excited state of the polaron and the coupling strength and magnetic field."
Li Kaichang frowned and said, "I'm afraid we need to get detailed and complete data before we can handle this."
On the side, Xu Chuan stared at the experimental data on the computer screen. He did not answer his words, but was silently thinking about what to calculate.
Xu Chuan didn't speak for a while, and the laboratory suddenly became quiet. Li Kaichang, who was staring at the experimental data and observing, looked over in confusion. Seeing that he was thinking, he suppressed the questions that came to his mouth.
In the laboratory, the magnetic polaron electromagnetic shield generator is constantly undergoing transformation experiments, and the large-scale SQUID superconducting quantum interference magnetometer is also continuously collecting relevant magnetic field data into the computer.
Just when the first round of experiments was about to end, a slightly excited voice sounded in the laboratory.
"Zeeman Split!"
Xu Chuan's voice rang in front of the computer screen. Li Kaichang, who was awakened, turned his head and looked over, and asked subconsciously.
"What?"
As if answering his question or talking to himself, Xu Chuan stared at the curve data on the computer screen with excitement in his eyes.
"That's right, it's Zeeman splitting!"
"The cyclotron resonance frequency of the magnetic polaron in the parabolic quantum dot splits into two branches. The binding energy of the ground state and excited state magnetic polaron as well as the resonance frequency of the magnetic polaron increase with the increase of the cyclotron frequency, and with the effective effect of the quantum dot
It decreases as the binding strength increases."
"If my judgment is correct, then the degree of splitting increases with the strengthening of the magnetic field. And as the magnetic field or temperature increases, the self-trapping energy of the magnetic polaron decreases, and the electron spin energy is less than the self-trapping energy of the magnetic polaron.
The ratio increases. When the magnetic field is strong enough or the temperature is high enough, the ratio of the electron spin energy to the magnetic polaron self-trapping energy will increase to a maximum value..."
Short and quick words rang out in the laboratory. Xu Chuan's eyes had moved away from the computer screen and stared at the magnetic polaron electromagnetic shield generator that had disconnected its power supply.
Perhaps, he knows how to optimize subsequent experiments.
Xu Chuan's words were like a thunder in Li Kaichang's heart. He was shocked and confused at the same time, as if he had caught some clues, but he couldn't fully understand them.
Suppressing the shock in his heart, he swallowed and continued: "What should we do?"
Hearing this question, Xu Chuan withdrew his gaze from the magnetic polaron electromagnetic shield generator and looked over, with a faint smile hanging on the corner of his mouth.
He smiled and said: "The ground state energy of magnetic polarons in quantum dots increases with the increase of characteristic frequency and cyclotron frequency. When considering the magnetic field and high temperature and high pressure at the same time, positive transformation and linear combination calculation can be applied
The symbol method is used to improve and study the influence of electron spin on the self-trapping energy of weakly coupled two-dimensional magnetic polarons."
"That is, when the characteristic frequency (or cyclotron resonance frequency) increases to a certain value, the magnetic polaron energy changes from negative to positive. The ground state energy increases as the column height decreases, and the smaller the column height, the faster the increase; when
When the column height decreases to a certain value, the magnetic polaron energy also changes from negative to positive..."
"In short, the ground state energy of magnetic polarons in quantum dots increases with the increase of magnetic field and decreases with the increase of the thickness of quantum dots. However, the ground state energy of magnetic polarons in cylindrical quantum dots is related to the scale of the quantum dot.
It is related to external magnetic field, characteristic frequency, etc.”
"As for how to do it..."
Speaking of this, Xu Chuan smiled confidently and continued: "Magnon is a quantized quasi-particle related to spin waves. It is the orderly excitation of spin in the crystal lattice. What is important is to change the intensity of a certain point in the crystal lattice.
Magnetization affects nearby locations like waves rippling on the surface of a calm pond."
"We simply measure the response to different tunings of photon-magnon coupling strength and position in the device with a magneto-electro-optic spectrometer, and then plot the results in a three-dimensional map of the special surface."
"Using nanotechnology to construct a matching magnon lattice excitation device is theoretically enough to complete the manufacturing of a magnetic polaron electromagnetic shield generator!"
...
It has to be said that scientific research equipment is really the core foundation of scientific research.
The data detected by the large-scale SQUID superconducting quantum interference magnetometer laboratory cannot be detected by the small magnetometer at Xinghai Research Institute.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! And this experimental data directly pointed out to Xu Chuan the problem with the magnetic polaron electromagnetic shield generator.
Although pointing out where the problem is does not mean that the problem can be solved directly, it is much better than the headless flies running around without knowing where the problem is.
Although the magnetic polaron problem in cylindrical quantum dots is only one of the problems of the magnetic polaron electromagnetic shield generator, in the magnetic polarization field, this problem is as important as high-temperature plasma turbulence control in controlled nuclear fusion technology.
Technology is one of the cores of the entire technology.
If they can solve this problem, there is no doubt that they can take a big step forward in plasma and electromagnetic deflection shield technology.
...
While Xu Chuan led the team to study plasma and electromagnetic deflection shield technology.
On the other side of the Eurasian continent, the high-luminosity LH-LHC large particle collider located one hundred meters underground in Geneva, Switzerland, is also conducting collision experiments at the moment.
The CRHPC Ring Super Particle Collider has not yet been officially completed. At this moment, CERN is still like a holy place in the world of physics, gathering countless physicists from all over the world.
In particular, the verification of the unified theory of strong electricity has attracted the attention of not only the physics community, but also governments of various countries, paying attention to the LH-LHC.
After all, whether it verifies that this theory is correct or fails, it will be a result that affects the development of the entire physics community.
Especially in China, although due to the drama with CERN, no physicists and university institutions have arranged for physicists to go to CERN to participate in the collision experiment this time. But it can be said that almost everyone from top to bottom is paying attention to the relevant information.
In CERN's headquarters building, busy staff are shuttled everywhere.
After the collider experiment is completed, the most important thing is undoubtedly the related data analysis work.
This is the first collision experiment to verify the unified theory of strong electricity. According to the tradition of CERN, data analysis is generally conducted by two or three different institutions or schools from different countries.
This time, CERN, under the influence of "hidden rules," distributed the data to two American universities and a physics research institution in England.
Although other CERN member states are somewhat dissatisfied with this allocation result, there is nothing they can do.
After all, in this LHC upgrade, the United States did make an extraordinary and extraordinary effort. It not only fulfilled its investment, but also provided a batch of high-temperature superconducting materials.
Moreover, other CERN member states also know very well that the reason why Lao Mi is so involved this time is mainly because he wants to suppress the country in the east of Eurasia in the field of basic science.
After all, with the failure of controllable nuclear fusion technology and failure in the aerospace field, the United States' position in the world is now in jeopardy.
The pattern of one superpower and multiple powers has long turned into a confrontation between east and west. The competition between the red and blue sides in the last century is re-enacted in the 21st century like a replica.
Although CERN has already intended to shut down the LHC collider and shift the focus of the field of high-energy physics to the rising Eastern power. After all, with the changes of the times, it has been difficult for the EU to bear the upgrading, collision and maintenance of the collider.
Waiting for related work.
But for North America, its successive failures in the energy and aerospace fields have made it difficult for them to accept another defeat in other fields.
Especially in areas such as chips and basic sciences that are at the core of national interests and development.
Although high-energy physics is only a part of the field of basic science, once this gap is opened, it means that basic science, at least in the field of physics, has begun to completely fall to China.
After all, a large strong particle collider is fatal to physicists, and nothing interests these scholars more than this.
It is difficult to form a systematic development in the field of basic science, but once formed, it is extremely easy to form a relationship and difficult to break.
Just like the United States used the Second World War in the last century to attract countless talents and almost monopolize the development of the entire basic disciplines, such as mathematics, physics, chemistry, etc., they still occupy a dominant position today.
The United States does not want to see its red opponent become stronger in these fields, even in the field of high-energy physics that may take decades or even longer to be applied.
...
CERN, in the headquarters building.
After the first collision experiment to verify the unified theory of strong electricity was completed, the two American universities that had obtained the original data immediately organized scholars to conduct analysis.
In the office, the physics team from Stanford University is working overtime to process the raw data.
"Gray, when will the data analysis in your hand be completed?"
Holding a cup of coffee, Professor Fox Hale, the leader of the physics group at Stanford University, walked in from the door and asked a young researcher who was sitting in front of the computer working hard.
"It's coming soon, Professor, give me another two days and I'll be able to complete it." Gray Dreiser's eyes widened, trying to find useful information in the raw data.
"come on!"
Hearing this answer, Fox Haier patted Gray on the shoulder with satisfaction and said with a smile: "This time we must be in front of Caltech and Cavendish Laboratory."
"This is a verification of the unified theory of strong electricity. As long as we can get a confidence level above 5sigma, we will definitely be able to become famous in one battle. Your bonus will also be quite generous!"
Competition in the field of high-energy physics has always been fierce. Whoever can find the exact signal first and draw the corresponding Dalitz diagram will belong to whom this honor belongs.
Not only do you have to compete for data analysis qualifications, but you also have to compete with peers who have also obtained data analysis qualifications for the speed of analysis.
It can be said that behind every data analysis is the result of the research team working overtime or even staying up all night.
And this time, the data analysis of the first collision experiment for the unified theory of strong electricity is naturally no exception, and it is more intense than before.
Because this is a unified theory of strong electricity, if we can complete its verification first, we may even have the opportunity to touch the dazzling Nobel Prize.
Although CERN groups will basically not be considered for the Nobel Prize, it is not impossible if they make a significant contribution to the exploration of a certain theory.
For example, the Nobel Prize in 1984 was awarded to Carlo Rubbia and Simon van der Meer who made decisive contributions to the large-scale project of field particles W and Z.
And I am afraid that no scholar will miss the opportunity to touch the Nobel Prize.
Thinking about it, Professor Fox Hale of Stanford University showed a pleasant smile on his face.
In his opinion, it was really stupid for China to withdraw from CERN three years ago. If China were still in CERN now, the verification of the unified theory of strong power would probably not be their turn at all.
After all, with Professor Xu here, others probably don't have the slightest chance.
Now, this opportunity is in front of us, it depends on who can seize it first.
