I really just want to be a scholar

Chapter 558 His report conquered the mathematicians in Bernhard's hometown!
In the early morning two days later, Qin Ke and Ning Qingyun met Professor Roger Koppett in the office of the teaching building of the Department of Mathematics at the University of Munich.

Professor Coppet is in his early 60s and is a typical Germanic man. He is tall and serious, and at first glance he is a serious but strict person.

Seeing Qin Ke and Ning Qingyun's exchange of greetings, he asked directly in English, "Are you Qin Ke?"

"Yes. Hello, Professor Koppett. This is a letter of recommendation from Mr. Faltings, because I want to seek a partner for a project related to quantum computing, and he recommended you to me." Qin Ke used this time It's German.

Hearing the familiar mother tongue, the resistance and coldness in Professor Coppett's eyes subsided a little.Although he can speak English, there is no doubt that German would make him feel more comfortable and communicate more easily.

Professor Copette didn't accept the recommendation letter from Qin Ke, but just stared at him and asked, "You major in physics, and you're only a sophomore this year?"

Qin Ke said neither humble nor overbearing: "Yes."

Professor Coppett raised his eyebrows: "Then do you know that in my team, doctoral students and postdoctoral students are basically required?"

Qin Ke made eye contact with him without flinching: "If Professor Coppett judges a person's actual ability by his academic qualifications, I think I can leave. Such a superficial person is not qualified to be my partner."

Professor Coppett looked at his confident expression, and thought that this kid was a bit interesting. He obviously came to ask for cooperation, but he always maintained an equal attitude.

"Let me ask you, sophomore physics freshman, do you understand quantum science?"

"I have completed all the professional courses in quantum physics and quantum information science by myself. In terms of quantum science, I should be no worse than any of your doctoral students."

Professor Copette laughed dumbfounded. He had heard about Qin Ke's reputation in mathematics for a long time, but a mathematician who is only 20 years old and has achieved such outstanding results in mathematics said that in physics, especially it is generally recognized as difficult. In terms of quantum theory, can it be compared to the doctoral students brought out by yourself?
This bragging is a bit too much.

You must know that the doctoral students he brought out are more than enough to be lecturers in other schools, and some outstanding ones can even be directly hired as associate professors.

He pulled a blackboard and wrote an equation: "HΨ=i/tΨ"

"Fill up the equation represented by H and show me."

Qin Ke smiled faintly, took the pen and finished writing in just a few seconds.

"H=^2/2m·^2/x^2+V(x,t)"

"Professor Koppett, you have the kindness to study me with such a simple single-particle one-dimensional Schrödinger equation. How much do you look down on me?"

Qin Ke wrote another set of equations that were several times more complicated as he spoke:

"Ψ(x, t)=∫[C1(E)ψE, 1(x)+C2(E)ψE, 2(x)]e^(iEt/)·dE"

Professor Coppett's pupils shrank slightly. This is the relationship between the energy E in the stationary Schrödinger equation and the two linearly independent solutions ψE, 1(x), ψE, 2(x), which can be written by hand like this It can be seen that Qin Ke has a deep understanding of the stationary Schrödinger equation, the eigenwave function, the Sturm-Liouville theory, and the eigenproblems of the Hermitian matrix.

Professor Coppett asked questions one after another, from quantum mechanics, tunneling effect, quantum entanglement, quantum system, quantum harmonic oscillator, to Hilbert space, Laplace operator, Fourier optics and propagation of light, and asked a whole lot Nearly 10 minutes.

Qin Ke was able to answer questions fluently throughout the whole process, and he was able to conduct in-depth exchanges with Professor Coppert by drawing inferences from one instance.

At this time, not only Professor Coppett was greatly moved, but even the assistant beside him was stunned, because the scope of Professor Coppett's questions became wider and wider, and the scope of questions became more and more biased. Even Professor Coppett The best doctoral students taught may not be so comprehensive and proficient in everything!
But this Xia Guo mathematician, who is only about 20 years old and is still in his sophomore year of undergraduate studies, has actually done it!

This is simply unbelievable. Could it be that Xia Guo's physical world has quietly developed to such a powerful point?Or is this young Xia country mathematician known as "Miracle Kid" also a genius in physics?

Professor Coppett couldn't help sighing in his heart, no wonder Faltings dared to recommend this young man to be his project partner. This young man has a solid foundation in quantum theory, and there are almost no dead ends. For quantum He is familiar with all sub-branches of scientific theory, the only thing he lacks is the grasp and understanding of the details of the experiment, which should be related to the fact that he has not carried out many related experiments.

However, from textbooks and literature alone, it is simply a miracle to be able to master quantum theory to such an extent.

As expected of a genius mathematician who was able to prove several world-class mathematical conjectures at a young age and won the Crawford Award, his talent in science is simply enviable. At least Professor Coppett himself, at the same age, Not even half of the opponent's level.

Professor Coppett's face has been greatly relieved. Qin Ke can join his research team just because of his level of quantum theory.

But what Professor Coppert needs most is the ability in mathematics to help him solve the bottleneck problem.

"Qin, I know that you are very good at theoretical mathematics, especially number theory, which is already at the top level in the world, but I don't know your level of functional analysis, topology, probability, and mathematical modeling. You know , My topic is related to topological quantum computing, the key core is to study quantum entanglement, which requires massive data analysis and modeling to confirm my hypothesis and improve the theory.”

Unknowingly, Professor Coppett's address for Qin Ke has become a more affectionate "Qin", which is the recognition of his physics level.

Qin Ke smiled and said to himself: "Although the international papers I usually publish are related to number theory, mathematical analysis is my specialty, especially mathematical modeling. Not only me, but my partner is also a mathematical An expert in modeling. If you agree, she can join me in this multinational project and work together on this project. Don't forget, she is also the winner of the Crawford Award."

As he spoke, Qin Ke took out a thick printed paper, which was the English version of the paper he had submitted on "Using the Karman Vortex Street Effect to Study High-Throughput Preparation of Ultrafine Fibers".

"This paper has been submitted to "Nature Materials", and we are responsible for all the data analysis and mathematical modeling in it."

Qin Ke took out three more Chinese versions of computational fluid dynamics papers: "This is a paper related to computational fluid dynamics, and it is enough to prove our ability in mathematical modeling."

Professor Coppett carefully flipped through the English version of the paper, and the look in his eyes gradually became serious.

He pondered for a moment, then looked up at Qin Ke: "You have basically convinced me, but because I have been fooled by a mathematician once, this time you and your partner want to join my research group, you have to go through a month's work." During the probationary period, if your performance during the period satisfies me, I will agree that you will officially become important members of my team, and the final project results will be signed and shared with you according to your contributions."

With Professor Coppert's status in the German physics community, it is very rare to be able to cooperate with a mathematician who is not well-known in the international physics community to conduct research on the subject, and he also promised to co-sign and share the results of the subject.

Qin Ke breathed a sigh of relief, knowing that this was the most ideal result, he stretched out his hand and said with a smile: "Yes."

Professor Coppert also extended his hand and shook it firmly with his.

"Before that, please allow me to say that you are welcome to join my topological quantum computing research group. Our goal is to achieve breakthrough results before the middle of next year, making the highest tolerable logic operation error rate in quantum error correction Raise to the level where quantum computing can be performed under experimental conditions!"

……

Qin Ke and Ning Qingjun stayed at the University of Munich for another two days, mainly following Professor Koppett and his team to get familiar with the situation of topological quantum computing and some necessary experimental operations.

Although theoretical physics is mainly based on theory, physics is inseparable from experiments. Topological quantum computing also requires experiments to verify the final results.Professor Koppett can apply to use the leading quantum computing laboratory in Germany at the University of Munich.

And in the past two days, Qin Ke and Ning Qingyun's physics and mathematics levels have also successfully convinced the team of Professor Copette. A dozen doctoral students in the team with high-sighted eyes, in the two When leaving, there was no contempt and resistance, and the two young college students from far eastern countries were kindly accepted and became important members of the team.

——The physics world is the same as the mathematics world, and strength always speaks, especially in a rigorous and somewhat rigid country like Deguo. Without strength, no matter how strong the background relationship is, it will not be recognized and accepted by others.

The strength of Qin Ke and Ning Qingyun undoubtedly achieved this.

After the division of labor and the agreement to communicate through encrypted emails, Qin Ke took Ning Qingyun to bid farewell to Professor Kopet and others, and returned to Bonn to continue to participate in the remaining academic reports.

At the academic report meeting of the Humboldt Research Award, Qin Ke's report is still the fourth set of expressions of the Riemann conjecture.

Bernhard Riemann is one of the most famous and greatest mathematicians in Germany. In his hometown, an academic report on Riemann's conjecture will naturally cause a strong sensation.

The original report video given by Qin Ke at the Crawford Prize has been circulated on the Internet. Many mathematicians from all over the world have already watched it, but they still rushed to Bonn to listen to the report again.

The prestige of Riemann's conjecture in the academic circles of Germany is almost the same as that of Goldbach's conjecture in the academic circles of Xia.

So Qin Ke's academic report naturally became the most popular one in the entire Humboldt Research Award academic report meeting. More than half of the German mathematicians sat in the audience, listening to this young man who was too young. Mathematicians of the Xia Kingdom revealed the mystery of the Riemann conjecture that they are most proud of and most eager to understand.

Among these mathematicians, some are disapproving, some are full of curiosity, some confirm their ideas, some are excited and looking forward to it, and some deliberately want to criticize.After all, there are so many mathematicians studying Riemann's conjecture in Germany, accounting for at least one-fifth of their counterparts in the world.

When Qin Ke began to give a report, even some arrogant "National Science Mathematicians" gave out imperceptible mocking smiles. In their eyes, only outstanding Germans could crack such a great proposition as the Riemann conjecture.

Qin Ke already knew the possible consequences of making such a report in Riemann's hometown. He calmly explained the derivation process of the fourth group of expressions of Riemann's conjecture in German in detail.

Originally, with his intermediate German level, he couldn't give such a professional math report fluently, but he had prepared in advance and translated the entire speech content into German through Shimmer, and asked the German professor of Kiyoki University to help revise it. Sometimes you only need to memorize the unfamiliar words and sentences in it. Naturally, it will not be difficult.

It came out really well in the end.

No one expected that Qin Ke would give a report in German, which made it easier for the audience to accept, until they saw the rigorous and flawless derivation process, and saw the young boy on the stage berating Fang Qiu. Slowly, the pickiness and disapproval in the audience's eyes disappeared, replaced by shock, excitement, amazement, and admiration.

At the end of the report, the audience was silent at first, and then the stormy applause sounded from every corner of the venue, and finally filled the entire venue space.

Facing the applause surging like a tide, Qin Ke smiled, took off his hat and bowed slightly in a very gentlemanly manner.

This scene was filmed by reporters.

The next day, "World Academic News", the most influential academic newspaper with the largest circulation in Germany, published a report titled "His Report Conquered the Mathematicians of Bernhard's Hometown!" ", the accompanying picture is Qin Ke's extremely aesthetic bow and thanks, while the background is full of excited cheers and applause from the audience.

At the end of the report, he commented: "Hundreds of mathematicians from all over the country tried to find the loopholes in the report of the Xia country mathematicians, but unfortunately, until the end of the whole report, no one This can be done. This means that the Miracle Boy from Xia Kingdom has successfully uncovered two-thirds of the mystery of Riemann's conjecture. Perhaps in the near future, we will be able to fully see the whole picture of Riemann's conjecture. let us wait and see!"

This report has aroused strong repercussions in German academic circles and even the public.

On the eve of Qin Ke's trip to Deguo and preparing to return, the Deguo Mathematical Society sent honorary membership certificates and medals, and the Deguo National Museum even sent a photocopy of the precious "Riemann Manuscripts" , in recognition of his great contribution to the Riemann Hypothesis.

You must know that most of Riemann's manuscripts have been burned or lost, including the booklet that recorded his thinking and research on the Riemann ζ function. The existing manuscripts are stored in the University of Göttingen and are regarded as the treasure of the town school. However, there is only a photocopy version in the German National Museum.

The photocopied copy given to Qin Ke is so clear that it is almost indistinguishable from the photocopied version in the Deguo National Museum.

Qin Ke accepted it after thanking him repeatedly. This precious manuscript material will be extremely important for him to understand the fifth set of expressions.

In mid-March, Qin Ke and Ning Qingyun, with honors and fresh applause, took a low-key flight back to Xiaguo to continue their studies in the last semester of their undergraduate studies.

And what greeted them in the motherland was naturally more flowers and applause.
