The Science Fiction World of Xueba

Before being transformed by genetically optimized medicines, Pang Xuelin seldom did research in the real world.

On the one hand, the time flow rate in the real world is 1:10,000 to the sci-fi plane, so it doesn't make much sense to retreat in the real world.

On the other hand, Pang Xuelin knows that his talent, at best, is due to the good study habits cultivated by his grandfather since he was a child, coupled with his persistent efforts, he was able to complete his doctoral studies at the age of 22.

However, after the modification of the gene optimization medicine, Pang Xuelin's memory and neural response speed have been greatly improved.

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

Therefore, this time, he wanted to try to see how far he could go when he devoted himself to a research work.

Pang Xuelin rebuilt a small study in the basement of Binjiang Villa.

The beds and bathrooms are complete.

For the next month or so, Pang Xuelin didn't hear anything outside the window, and stayed in the study every day to do research.

When he was hungry, someone would deliver food, and when his body was rotten, he would think of taking a bath and changing into clean clothes.

He doesn't know the passage of time and only exists in his own world every day.

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

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

Electromagnetic space launch systems and aerospace aircraft, from super-large-capacity energy storage systems to large linear motors, from space life cycle support systems to high-thrust Hall thrusters, from the related applications of aerospace-grade carbon-based chips to orbit design, from launch From control systems to supercomputers based on carbon-based chips...

There are not only basic physics, chemistry, mathematics, information science, biology, basic medicine, but also engineering.

These papers are not those of hydrology 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 were many papers that Pang Xuelin couldn't understand at once, when he integrated the knowledge into his mind, it greatly expanded Pang Xuelin's cognitive boundary.

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

Of course, in the field of superconductivity, Pang Xuelin is not without gains.

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

Among them, two papers attracted Pang Xuelin's attention, one was "Unconventional Superconductivity and Quantum Criticality in Heavy Fermion Compounds", and the other was "Superconductivity in Two-dimensional Electronic Systems under Microwave Irradiation ".

The so-called heavy fermion compounds in the first paper are generally intermetallic compounds based on lanthanides and actinides, usually with unfilled f-electron shells.

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

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

Unconventional superconductivity and quantum critical behavior in heavy fermion compounds exhibit many features similar to cuprate high-temperature superconductors,

Its physical description goes beyond the theoretical framework of the classic Landau Fermi liquid theory and the traditional BCS superconducting theory.

In this paper, the scientists found that there are two different superconducting states in the CeCu2Si2 material, the low-voltage superconducting phase is similar to other heavy fermion superconducting states, and another new high-voltage superconducting state appears in the valence electron quantum phase Near the change point.

At the magneto-induced superconducting quantum phase transition point, the Wiedemann-Franz law generally followed in metals is broken in heavy fermion superconductors5.

In addition, there is also experimental evidence that a theoretically predicted Fulde-Ferrell-Larkin-Ovikov (FFLO) superconducting phase may exist near the upper critical magnetic field of 5 superconductivity.

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

When the antiferromagnetic phase of 5 was gradually suppressed by pressure, the scientists found that the magnetically induced quantum phase transition appeared 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 gave the many-body wave function in the strong correlation model of heavy fermion compound materials, trying to obtain a definite superconducting state by solving the complete strict solution in the multi-wave body function.

In another paper, "Superconductivity in Two-Dimensional Electronic Systems Under Microwave Irradiation", the scientists' findings were basically the same as those of Cao Yuan, who also discovered superconductivity in a two-dimensional electronic system composed of graphene.

The only difference between the two is that what Cao Yuan and his colleagues discovered was to realize the superconductivity of the graphene two-dimensional electronic system through low temperature and changing the electric field strength.

In this paper, the scientists realized the superconductivity of the two-dimensional electronic system through low temperature and changing the intensity of microwave irradiation.

After further investigation, the scientists found that at lower magnetic fields away from the quantum Hall state, the two-dimensional electronic system exhibits a novel magnetoresistance oscillation with a periodic structure available at the microwave frequency ω and the cyclotron resonance frequency ωc (Landau energy level interval) is characterized by the ratio ε≡ω/ωc: when ε is approximately an integer (ε≈n), it corresponds to an oscillation peak, and when ε is approximately a half-integer (ε≈n +1/2 ), it corresponds to an oscillation valley.

Compared to the magnetoresistance without microwaves, the microwave contribution to the magnetoresistance is positive at the oscillation peaks and negative at the oscillation valleys. Further experiments found that as the sample became more and more pure, the oscillation caused by microwaves became more and more the dominant feature of the magnetoresistance of the sample, and the resistance value of the oscillation valley became smaller and smaller, tending to become zero.

Finally, the scientists observed on a very pure sample that under microwave excitation, the resistance value of the magnetoresistance oscillation valley tends to zero exponentially as the temperature decreases, which is the so-called superconductivity of the two-dimensional electronic system under microwave irradiation. Phenomenon.

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

But before he could figure out the connection between the two, someone knocked on the door of the room that had been closed for many days.

Pang Xuelin was stunned for a long time, and then remembered that before he entered the retreat state, he had told Zuo Yiqiu to ask her to come and find him on December 8th.

During this period of research and thinking day and night, Pang Xuelin has no concept of time at all, and all his attention is placed on those papers.

Three meals a day and a change of clothes are exchanged through a small window.

"Hey, it's been a long time since I've been in such a state of devotion to research. It feels so good, but it's a pity that time flies too fast."

Pang Xuelin stood up from the desk and stretched long.

This kind of research state, he had only experienced it when he was working on nonlinear partial differential equations in the Martian world and the world of Wandering Earth.

Perhaps because of the gene optimization medicine, Pang Xuelin didn't feel tired after thinking for a long time for more than a month, but was full of energy and spirit.

He walked to the door, opened the door, and saw Zuo Yiqiu, Yao Bingxia, and Qi Xin standing at the door, looking at him worriedly.

"Xiao Xia, Ah Xin."

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

Zuo Yiqiu looked at Pang Xuelin in shock.

If before, she was only in admiration of Pang Xuelin's academic ability and extraordinary talent, then now, she had a faint feeling of awe towards Pang Xuelin.

She never thought that a scientist with such a high status could lock herself in a small room and not communicate with the outside world for more than a month in order to conduct research.

Ordinary people would probably go crazy if they were locked up like this.

But even though Pang Xuelin had been in seclusion for so long, apart from his unshaven beard and his hair had grown a lot, his whole person looked radiant, especially his eyes, which were as bright as stars.

Zuo Yiqiu said: "Pang...Professor Pang, our plane leaves for Stockholm at 11:30 this evening. It is now 9:00 in the morning, so we can start preparations."

At this moment, Yao Bingxia on the side covered his nose and said, "Brother Xiao Lin, how long has it been since you took a shower?"

Pang Xuelin sniffed himself from left to right and said: "It seems like more than ten days ago, I forgot too, it doesn't smell bad."

Qi Xin smiled and said: "You don't smell bad, I smelled a bad smell from a long distance away, let's go, take a bath quickly, shave your beard, and take care of your hair later. In addition, me and Xiaoxia helped you choose several sets of tuxedos for this Nobel Prize presentation ceremony, and I will change them later."

With that said, the two women, one on the left and the other on the right, pulled Pang Xuelin out of the basement.

...

The shower time is a bit long.

First, Pang Xuelin went back 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 Pang Xuelin and the three of them came out of the room, it was already lunch time.

Zuo Yiqiu looked at the pale pink faces of Yao Bingxia and Qi Xin, and couldn't help but complain in his heart: "Shameless."

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

It took Pang Xuelin three or four hours to try on clothes for five sets of regular clothes and three sets of dresses, which was more tiring than Pang Xuelin's research paper.

But including Zuo Yiqiu, the three girls were all a little bit bored, and even commented on Pang Xuelin's attire,

In the evening, parents, grandparents and grandparents all rushed over, they were Pang Xuelin's relatives and friends attending the Nobel Prize Ceremony this time.

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

At 6 o'clock in the evening, everyone had dinner in the villa, and then boarded a mighty convoy to Jiangcheng International Airport to join Kirton Walker's team.

Attending the Nobel Prize Ceremony this time, in addition to Kirton Walker and his two children, Jiang University President Xu Xincheng, 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 all accompanied them.

In addition, there are accompanying media reporters.

The reporter of CCTV news even began to broadcast the whole process on the web when Pang Xuelin and the others arrived at the airport.

On Weibo, the number of netizens who simultaneously watched the live broadcast exceeded 30 million.

"Haha, come here and check in. I can finally see for myself how to receive the Nobel Prize?"

"To be honest, I don't know why. When Mr. Tu won the award last time, he didn't feel this excited. Maybe it's because Mr. Tu's achievement was decades ago. On the contrary, I was very excited to see Professor Pang accept the award this time. .”

"Same as above, thanks to Professor Pang. In a few months, Jinlong battery will be officially launched. I am saving money to buy a Jinlong battery mobile phone. When I go out, I can finally play with my mobile phone without looking at the battery."

"I hope everyone will not forget Professor Kirton Walker. This time, two Chinese people won the award at the same time."

"Yes, Professor Pang deserves respect, and so does Professor Kirton Walker!"

"I saw Miss Qi Xin, she is so beautiful..."

"I'll go, the two girls behind Professor Pang are also super beautiful..."

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

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

...

This massive live broadcast was not interrupted until they got on the plane.

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

There was no words all the way. Thirteen hours later, it was not until 8:30 a.m. local time on December 9 that Pang Xuelin's special plane arrived at Stockholm Arlanda International Airport.

Lars Heikensten, chairman of the Nobel Foundation, and Herbert Green, chairman of the Nobel Prize in Chemistry judging committee, were greeted at the airport.

After a short greeting at the airport, everyone went directly to the Stockholm Grand Hotel in the center of Stockholm.

It's winter in Sweden now, even though it's almost nine o'clock in the morning, the sky is still dark, snowflakes are falling from the sky, and the street lights on the street corners are still on.

At the entrance of the hotel, reporters from major media outlets around the world had been waiting for a long time. When Pang Xuelin and his convoy arrived, the flashing lights blared even more.

Pang Xuelin and his family directly stayed in the presidential suite of this hotel, while Zuo Yiqiu and Zhou Chen lived in the executive suite downstairs.

The next day, Pang Xuelin and the others mostly rested in the room to overcome jet lag.
