MTL - The Science Fiction World of Xueba-Chapter 379 Exit

Prior to genetically optimized pharmaceutical transformation, Pang Xuelin rarely conducted research in the real world.

On the one hand, the time velocity of the real world and the sci-fi plane is 1: 10000, which is of little significance in the real world retreat.

On the other hand, Pang Xuelin knew his talent. At best, it was because of the good study habits cultivated by grandpa from an early age, and his persistent efforts to complete his Ph.D. at the age of 22.

However, after genetically optimized medicament modification, Pang Xuelin has greatly improved both his memory and neural response speed.

From the perspective of IQ, ， has reached the peak of human existence.

Therefore, this time, he wanted to try to what extent he could reach when he devoted himself to a research work.

Xi Pang Xuelin converted a small study in the basement of the Riverside Villa.

The bed and toilet are complete.

For the next month or so, Pang Xuelin turned a blind eye to events outside the window and stayed in the study every day for research.

When I was hungry, someone would naturally deliver meals. When I was stunned, he thought of going to take a bath and then changed into clean clothes.

不 He doesn't know how time passes, and only exists in his own world every day.

He mainly focused on the content of quantum computers brought back from the world of rural teachers, and the related technical materials of the electromagnetic ejection space launch system and aerospace aircraft brought back from the dark forest world.

The field of quantum computers, from various quantum logic components to physical implementation, from quantum to physical limits of information processing to quantum algorithms, from quantum error correction to quantum coding, from decoherence of macroscopic objects to classical reduction of the quantum universe ...

Electromagnetic aerospace launch systems and aerospace aircrafts, from ultra-large-capacity energy storage systems to large linear motors, from space life cycle support systems to high-thrust Hall thrusters, from related applications of space-grade carbon-based chips to orbital design, from launch Control systems to supercomputers based on carbon-based chips ...

There are contents in basic physics, chemistry, mathematics, information science, biology, basic medicine, and engineering.

论文 These papers are not those in the real world. Each one is enough to form a breakthrough in some professional fields or open up a new research direction.

These papers took root in Pang Xuelin's mind one by one. Although there are many papers Pang Xuelin couldn't understand at once, when he put these knowledge into his mind, he greatly expanded Pang Xuelin's cognitive boundary.

And after such a retreat study, Pang Xuelin has a deeper understanding of how to complete the electromagnetic space launch project in the real world planning office.

Of course, in the superconducting field, Pang Xuelin is not without gain.

Of the hundreds of papers he has read, nearly ten are related to superconductivity.

Two of them attracted the attention of Pang Xuelin, one was "Unconventional superconductivity and quantum criticality in heavy fermion compounds" and the other was "Superconductivity of two-dimensional electronic systems in microwave irradiation" ".

The so-called heavy fermion compound in the first paper is generally an intermetallic compound formed based on lanthanides and actinides, and usually has an unfilled f-electron shell.

这类 In this kind of material, the effective mass of the carrier increases sharply due to the hybridization of the local f-layer electrons and the conduction electrons, which can reach more than 1000 times the free electrons, so it is also called a heavy electron compound.

Germany A.P. Drozdov's team confirmed that when the pressure is 1 million earth atmospheres, various hydrogen-rich lanthanide metal hydrides become superconductors at about 250K, which is based on this material.

The unconventional superconductivity and quantum critical behavior in heavy fermion compounds show many characteristics similar to those of copper-oxygen high-temperature superconductors, but their physical descriptions surpass the classic Landau Fermi liquid theory and traditional BCS superconducting theory. Theoretical framework.

In this paper, scientists have discovered that CeCu2Si2 material has two different superconducting states. The low-pressure superconducting phase is similar to other heavy fermion superconducting states, and another new high-pressure superconducting state appears in the valence electron quantum phase. Near the point of change.

At the magnetically induced superconducting quantum phase transition point, the Wiedemann-Franz law, which is generally followed in metals, is destroyed in the heavy fermion superconductor 5.

In addition, there is experimental evidence that a theoretical Fulde-Ferrell-Larkin-Ovikov (FFLO) superconducting phase predicted in the 1960s may exist near the 5th superconducting upper critical magnetic field.

Below the upper critical magnetic field, 5 shows a rich magnetic flux phase diagram and cannot be described by the traditional Abrikosov magnetic flux lattice model.

When the antiferromagnetic phase of 5 was gradually suppressed by pressure, scientists found that magnetically induced quantum phase transitions occurred in the superconducting phase.

Based on these evidences, it is sufficient to show that the formation of heavy fermion superconductivity is closely related to spin fluctuations.

In this paper, the scientists also presented the multi-body wave function in the strong correlation model of heavy fermion compound materials, in an attempt to obtain a clear superconducting state by solving the completely rigorous solution in the multi-wave body function.

另一 In another paper, "Superconductivity of Two-Dimensional Electronic Systems in Microwave Irradiation", the scientists found that they were basically the same as Cao Yuan's. They also found superconductivity in two-dimensional electronic systems composed of graphene.

The only difference between the two is that Cao Yuan and his team discovered that the superconductivity of graphene's two-dimensional electronic system can be achieved by low temperature and changing the electric field strength.

In this paper, scientists realized the superconducting phenomenon of two-dimensional electronic systems by lowering the temperature and changing the intensity of microwave irradiation.

After further research, scientists have discovered that the two-dimensional electronic system exhibits a novel reluctance oscillation in a lower magnetic field far from the quantum Hall state. Its periodic structure can use microwave frequency ω and cyclotron resonance frequency ωc (Landau energy level Interval) is characterized by the ratio ε≡ω / ωc: when ε is about an integer (ε≈n), it corresponds to an oscillation peak, and when ε is about a half integer (ε≈n + 1/2), it corresponds to an oscillation valley.

相比 Compared with the magnetoresistance without microwave, the contribution of microwave to the magnetoresistance is positive at the oscillation peak and negative at the oscillation valley. Further experiments found that as the sample becomes more and more pure, the oscillation caused by microwave becomes more and more the dominant characteristic of the sample's magnetoresistance, and the resistance value of the oscillation valley becomes smaller and smaller and tends to become zero.

In the end, scientists observed on a very pure sample that the resistance value of the magnetoresistive oscillation valley under microwave excitation decreases exponentially with temperature, which is the so-called two-dimensional electronic system superconductivity under microwave irradiation. phenomenon.

The superconducting phenomenon exhibited by the graphene two-dimensional electronic system in electric fields and microwave irradiation, and the relationship between the formation of heavy fermion superconductors and spin fluctuations, made Pang Xuelin faintly feel that between the two There is some mysterious internal connection.

He just hadn't waited for him to figure out the connection between the two, and finally closed the door of the room for many days.

Xun Pang Xuelin spent a long time in the middle, and then she remembered that she had told Zuo Yiqiu before entering the retreat and asked her to come and find her on December 8.

During this time, there was no day to night research and thinking. Pang Xuelin didn't have much time concept at all. All his attention was focused on those papers.

三 Three meals a day and changing clothes are exchanged through a small window.

哎 "Hey, I haven't entered such a state of research for a long time, and it feels good, but unfortunately time has passed too quickly."

Xi Pang Xuelin stood up from the desk and stretched a long waist.

In this state of research, he also experienced it when he first worked on nonlinear partial differential equations in the Martian rescue world and the stray earth world.

Perhaps because of genetically optimized medicaments, and continued thinking for more than a month, Pang Xuelin didn't feel much tired, but was full of energy and energy.

He went to the door, opened the door, and saw Zuo Yiqiu, Yao Bingxia, and Qi Xin, the three daughters standing at the door, looking at themselves anxiously.

"Xiaoxia, Axin."

Xi Pang Xuelin smiled and nodded towards Yao Bingxia and Qi Xin, turned his head to Zuo Yiqiu and said, "Xiao Zuo, it's December 8th so soon?"

Wu Zuoqiu looked at Pang Xuelin with shock.

If before, she just admired Pang Xuelin's academic ability and extraordinary talent, then now, for Pang Xuelin, she has a faint feeling of awe.

She never thought that a scientist who had such a high status could confine herself in a small house for research, and would not contact the outside world for more than a month.

I am ordinary people being so locked up, I'm afraid they have to go crazy.

Although Ke Pang Xuelin has been in retreat for so long, in addition to his beard and hair, his hair has grown a lot, but the whole person looks energetic, especially those eyes, even more like a star.

Zuo Yiqiu said: "Professor Pang ... Pang, we will fly to Stockholm at 11.30 this evening. It is now 9 am, and we are almost ready to start."

At this moment, Yao Bingxia covering her nose said, "Brother Xiaolin, how long have you been out of the shower?"

Pan Pang Xuelin sniffed around and said to himself, "It seems like ten days ago, I also forgot, there is no smell."

Qi Xin laughed: "You still don't smell bad. I smell a lot of smell all the way. Go, take a shower, shave my beard, and take care of my hair later. In addition, I and Xiao Xia helped you choose several sets of tuxedos to attend the Nobel Prize Presentation Ceremony.

He said, the two women left and right, pulling Pang Xuelin apart from the basement.

Uh ...

It takes a long time to bathe.

First, Pang Xuelin returned to the bathtub in his bedroom to take a bath. Then it seemed that something was missing. Yao Bingxia was pulled in, and then something was missing. Qi Xin was also pulled in.

By the time Peng Xuelin and the three of them came out of the room, it was already lunch time.

Tong Zuo Yiqiu looked at the faint pink on Yao Bingxia and Qi Xin's faces, and couldn't help but uttered a sentence: "Shameless."

In the afternoon, Pang Xuelin first went to make a hairstyle, and then with the help of the three women, he began to try various styles.

Five sets of regular clothes and three sets of dresses. It took Pang Xuelin three or four hours to test the clothes alone, which was more tiring than Pang Xuelin's research thesis.

But the three women, including Zuo Yiqiu, are not too tired. They even talk about the clothes of Pang Xuelin,

In the evening, parents and grandparents rushed over. It was Pang Xuelin's relatives and friends group who participated in the Nobel Prize award ceremony.

Yao Bingxia, Qi Xin, Zuo Yiqiu, and Zhou Chen will follow.

六 At six in the evening, everyone had dinner in the villa, and then boarded the mighty convoy to Jiangcheng International Airport to meet with Kirton Walker's team.

出席 In addition to Kirton Walker and his two children attending the Nobel Prize Presentation Ceremony, President Xu Xincheng of Jiang University, some members of the lithium-air battery project team, the Ministry of Foreign Affairs, the Ministry of Science and Technology, and the Chinese Academy of Sciences were also accompanied.

In addition, there are accompanying media reporters.

CCTV News reporters even started a live webcast all the way when Pang Xuelin arrived at the airport.

微 On Weibo, the number of netizens watching this live broadcast exceeded 30 million.

"Haha, come here to check in, and finally you can see for yourself how to get the Nobel Prize?"

"To be honest, I don't know why, when Mr. Tu won the award last time, he didn't feel this kind of excitement. Perhaps it was the result of Mr. Tu's achievements decades ago. On the contrary, he was particularly excited to see Professor Pang go to receive the award. . "

"Ibid, thanks to Professor Pang. In a few months, Jinlong Battery will be officially launched. It is saving money to start a Jinlong battery mobile phone. When it is time to go out, you can finally play with your mobile phone without holding power ~ www.novelbuddy.com ~ I hope everyone will not forget Professor Kirton Walker. This time, two Chinese people won awards at the same time. "

"Yes, Professor Pang deserves respect, and Professor Corton Walker deserves respect!"

"I saw Miss Qi Xin, so pretty ..."

我 "I'm going, the two girls behind Professor Pang are also very beautiful ..."

"Is this the so-called Yan Ruyu in the book?"

"To be honest, I'm sore ..."

Uh ...

This huge live broadcast was not interrupted until the plane was boarded.

Everyone entered the airport through the VIP channel and boarded a charter flight from Air China.

There was no speech on the way. Thirteen hours later, until 8:30 a.m. local time on December 9th, Pang Xuelin's special plane arrived at Stockholm Arlanda International Airport smoothly.

I was greeted at the airport by Lars Heikenstein, Chairman of the Nobel Foundation, and Herbert Green, Chairman of the Nobel Prize Committee for Chemistry.

After a few moments of chilling at the airport, everyone went directly to the Stockholm Grand Hotel in central Stockholm.

It is winter in Sweden now. Even when it is almost nine o’clock in the morning, the sky is still dim, snow is falling from the sky, and street lights are still on.

At the door of the hotel, journalists from major media around the world have been waiting for a long time. When Pang Xuelin and his team arrived, the flashing lights became even louder.

Xi Pang Xuelin and his family checked into the presidential suite of this hotel directly. Zuo Yiqiu and Zhou Chen, their entourage, lived in the executive suite downstairs.

The next day, Pang Xuelin mostly had jet lag in their room.
