I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 655 Is this a recruitment drive for us?

Xu Qingzhou had already published his paper proving the Riemann Hypothesis on arXiv, but it was different from the official announcement by the Clay Institute.

Publishing the results can garner discussion in the academic community and even gain the support of 80% of scholars, but the intellectual property rights remain ambiguous and can still be questioned as "partial verification rather than complete proof."

Publicly declaring oneself is equivalent to making a declaration in the academic square, while Clay certification is equivalent to the Civilization Council promulgating a code.

The Clay Institute's announcement of Xu Qingzhou's findings on its official website can be considered a definitive conclusion, bringing a period to the path of proving the Riemann Hypothesis.

It can be said that only through Clay certification can the solution to the Riemann Hypothesis be elevated from an "individual breakthrough" to a "civilizational axiom." Of course, this is an exaggeration. Whether mathematical truths are correct is not subject to human will, nor does it rely on the endorsement of a single research institute.

However, it is undeniable that more than 90% of people will have fewer doubts.

The news sparked heated discussions online, and official media outlets also reposted the relevant news.

Xu Qingzhou wasn't particularly excited; he continued his life as usual, engrossed in calculations.

Two days later, the online buzz finally died down, and the libraries of Kyoto University and MIT respectively established "Riemann Hypothesis Special Archives".

In his office, Xu Qingzhou stared blankly at the manuscript in front of him.

After he solved the problem that the intense thermal motion of ions made it difficult for the spin polarization decoherence time to provide a stable carrier for the spin locking effect, three more technical difficulties emerged in the quantum spin-dynamic topological coupling model.

First, the computational complexity of cross-scale modeling, the difference in spatiotemporal resolution between the phase field method and topology optimization requires adaptive meshing, which increases the computation time by 3-5 times.

This is a piece of cake for the research institute's supercomputer.

Secondly, the difficulty of experimental-model co-validation: dynamic imaging of lithium deposition requires the combined use of synchrotron radiation XAS and cryo-electron microscopy, which is not a problem for Xu Qingzhou.

Don't forget, he spent over 100 million to buy electron microscopes, making capturing the dynamics of lithium deposition a piece of cake.

Thirdly, the numerical instability of nonlinear systems is perhaps the most challenging problem.

In numerical solutions, the condition number of the Jacobian matrix increases sharply to (>10^{12}) under the superposition of nonlinear coupling terms, such as double-well potential and SIMP penalty factor, causing the iterative trajectory to deviate from the true solution.

To put it more vividly, it's like a roller coaster going out of control and veering off the track at a sharp turn, or like a loose thread causing the entire fabric to disintegrate during weaving.

Assistant Wang Sidong knocked on the door and came in.

"Professor, this is the construction plan for the compact magnet system that Academician Ren had sent over."

Wang Sidong handed over a document.

"it is good."

Xu Qingzhou nodded.

Wang Sidong asked considerately, "Would you like a cup of coffee?"

"Iced Americano".

Xu Qingzhou thought for a moment and then ordered a cup of coffee to perk himself up.

"Okay, come right away."

Wang Sidong was very efficient; he brought the coffee over in just two minutes.

Xu Qingzhou took a sip of coffee and continued to look through the proposal that Zhao Shengwen had sent over.

Currently, the fusion group has two tasks: one is to build a compact magnet system, and the other is to test the performance of superconducting thin films under extreme environments.

“A single set of compact magnets requires at least 300 square meters of experimental space, including a winding area, a testing area, and a storage area.” Xu Qingzhou flipped through the drawings and related equipment information.

The experimental site was chosen in the southwest of the institute, near the Summer Palace, and close to Experiment Building No. 3, which has a superconducting thin film deposition system.

Previous simulations of superconducting thin films' performance under extreme conditions relied on mathematical reasoning. The first task for controlled nuclear fusion is to initiate the extreme condition verification of superconducting thin film materials in May, using a 1 MeV-level ion beam device for equivalent neutron irradiation verification, covering a fusion reactor flux simulation of 10 n/cm. This can effectively avoid large-scale trial and error later on.

During this period, the prototype of a compact magnet system was built simultaneously, equipped with machines such as laser positioning winding machines and vacuum impregnation systems, and high-performance superconducting thin films were transformed into operable magnet modules.

Superconducting thin film verification lays the material foundation for magnet prototypes, while magnet integration reverse-verifies the direction of thin film process optimization, forming a closed technology loop.

"Academician Ren is really efficient."

Xu Qingzhou finished reading the plan and nodded slightly. With Academician Ren overseeing things, he felt much more at ease.

After spending an hour reviewing the plan, he rubbed his aching temples, picked up his pen to do calculations, and said, "Let's get back to the calculations."

3 month 6 day.

Academician Zhang Zhigao and his team from the Southwest Institute of Physics made an official visit.

Xu Qingzhou led the welcoming party. Zhang Zhigao looked to be about the same age as Ren Nan, a tall, thin old man wearing glasses.

"Academician Ren."

After Zhang Zhigao and Xu Qingzhou shook hands and exchanged pleasantries, Zhang Zhigao looked at Academician Ren Nan standing to the side. Although they disliked each other, they were all respectable people and it was not to the point of a passionate argument.

"Welcome, Academician Zhang."

Ren Nan reached out his hand, his expression indifferent. Although he disapproved of Zhang Zhigao's behavior at times, he had to admit that this guy was definitely among the top technicians in the field of fusion.

"I've heard that the Kyoto Institute for Materials Science is extraordinary, and I've always wanted to come and see it. Today, I've seen it for myself, and it's indeed different from other institutes. The research atmosphere is very strong."

"You flatter me, Academician Zhang, please go ahead."

Everyone walked together into the research institute.

After being greeted, we visited the superconducting thin film laboratory according to the schedule, followed by a day of exchange meetings.

Zhang Zhigao presented the latest advanced technologies such as divertor configuration control and high-power neutral beam injection. Xu Qingzhou's team, Gao Wenjin, presented a report on experiments such as superconducting thin film radiation resistance, Jc attenuation, and interface stripping.

The whole process was harmonious, and there were no unpleasant incidents due to the matter between Ren Nan and Zhang Zhigao.

It's even a bit hot.

Li Yi and Zhang Zhigao's students even discussed the design of superconducting magnets while eating.

After the conversation, Zhang Zhigao went to Xu Qingzhou's office alone.

"Tea, please."

"Professor Xu, this Da Hong Pao is excellent. The aroma is long-lasting, and the tea soup is rich and smooth. It's a top-quality product."

"I'm happy with whatever you like." Xu Qingzhou smiled. It seemed that Academician Zhang had come to see him alone because he had something on his mind.

"Professor Xu, now that you've decided to pursue a fusion project, have you considered collaborating with other organizations?"

After drinking tea for a while, Zhang Zhigao smiled and said, "If you're willing, we can transfer some of the experiments from the Circulation-3 satellite to the Kyoto Institute for Materials Science, and apply for the National Magnetic Confinement Special Fund through the Southwest Institute of Physics. Your R&D subsidy ratio can be increased to at least 60%, and in addition..."

"We can also use the port of the Circulation No. 3 vacuum chamber for priority verification of superconducting magnet dynamic confinement. Our requirements are simple: the patent for the joint research and development results must list us as the first right holder."

Upon hearing this, Xu Qingzhou frowned. This meant that the fusion project team of the institute was basically a subordinate research institution of the Southwest Institute of Physics.

Well, it turns out that Academician Zhang used the Circulation-3 satellite as bait to recruit them.
