From top student in college to scientific research powerhouse

Chapter 55 You can't lead your child down a dead end!

"The known conclusion is that the growth of stanene is specific and related to the static magnetism of the bismuth telluride surface."

"Stanene possesses the characteristic of having both 100% edge conductivity and superconductivity, and its theoretical framework necessitates the study of strongly correlated electron systems..."

"The Ferm Hubbard model is unavoidable!"

Zhang Minghao scratched his head in frustration.

The fermion Hubbard model, used to describe the motion of correlated electrons in a crystal lattice, is considered one of the core theoretical frameworks for studying the mechanism of high-temperature superconductivity.

Because of its importance, many teams both at home and abroad are studying how to solve the model.

The difficulty in solving the fermion Hubbard model lies in the fact that there is no strictly analytical solution in the two-dimensional or three-dimensional case. In addition, its computational complexity far exceeds the capabilities of classical computers.

One approach to studying the fermion Hubbard model is to use an ultracold atom quantum simulator to simulate the motion of fermions within a crystal lattice at ultra-low temperatures, in order to understand the physical laws described by the fermion Hubbard model.

Simply put, it involves using a quantum simulator to simulate the Hubbard model of fermions.

Even so, the results were meager.

Simulating a 'part' of the laws of the Hubbard model of fermions using a quantum simulator is a research achievement worthy of being published in one of the top three international journals.

This demonstrates just how complex it is to solve the fermion Hubbard model.

Zhang Minghao pondered for a moment, then decided to give "Correct Perception" a try—

Is it possible to solve the fermion Hubbard model?
The difficulty level is too high; no feedback was received.

Is it possible to bypass the fermion Hubbard model to analyze the correlation between the specific growth characteristics of stanene and the static magnetism of bismuth telluride surface?
can.

Feedback has emerged regarding "Correct Perception," but the problem is that there are simply too many 'bypass' methods.

If he could easily come up with a solution, he wouldn't have bothered with the fermion Hubbard model.

How do we get around it?

"To describe the electronic motion laws of superconductivity, it is best to perform analytical and numerical analysis in order to connect it with the magnetic characteristics of the bismuth telluride surface..."

Chen Shuai arrived at the workroom.

After he entered, he asked Chen Lanjun about her work progress, and the two talked for a long time.

After finishing speaking, Chen Shuai turned to leave, but noticed Zhang Minghao scratching his head beside him and immediately asked, "What's wrong? What are you thinking about? Is it so difficult?"

He pointed to himself and joked, "Don't mess with your hair, or you'll end up like me."

Zhang Minghao noticed Chen Shuai's sparse scalp and quickly put his hand down.

He explained, “Professor Chen, I’m thinking about the magnetic correlation problem you discovered.”

"The correlation between the static magnetism of bismuth telluride surface and its properties in promoting stanene growth."

As soon as he finished speaking, Chen Shuai asked, "Are you talking about the third connection I analyzed?"

"Correct."

"Any questions? I mean... what do you think?"

Chen Shuai sounded a little nervous as he spoke.

Zhang Minghao said, "I believe that magnetic correlation exists, so I want to analyze the basic principles behind it, but I've encountered a major problem: the research cannot bypass the superconductivity of stanene..."

"This necessitates the use of the fermion Hubbard model, but solving the model..."

He went on and on.

Chen Shuai didn't even finish listening; he only had one thing on his mind—Zhang Minghao believed in the existence of 'magnetic correlation' and even wanted to use it as a basis for research on fundamental principles.

"Okay!"

Chen Shuai said excitedly, "I think so too, there must be a connection!"

He was genuinely excited!
The current research method was proposed by Zhang Minghao, because it requires extensive data analysis to draw conclusions before conducting experimental verification.

In the entire project team, Chen Shuai, who specializes in computational physics, became the most crucial figure.

Chen Shuai and his doctoral students conducted the analysis together and found a kind of 'possible or nonexistent correlation'. Then, the others carried out experiments based on the analysis results.

Being a key figure sounds good, but the work pressure is also enormous.

Chen Shuai knew his abilities were limited; he himself wasn't very confident in the results of his analysis, let alone others.

Some doctoral students didn't trust him much, and the level of trust among other associate researchers, and then among project leaders Zhu Bingkun and Xue Kun, was even more pitiful.

Zhu Bingkun comforted him by saying, "We've already wasted a year, so another year won't matter."

"Old Chen, just focus on your analysis. Whether it's right or wrong, we'll use it as a reference for our experiments!"

Xue Kun chimed in, "Director Zhu is right!"

You can tell from that you have no hope!

Now that he knows Zhang Minghao believes in the connections he analyzed and even plans to use them to study the underlying principles, Chen Shuai's feelings are easy to imagine.

He was excited for a long time, telling Zhang Minghao a lot about how to analyze and research, and finally asked, "What about the other two connections?"

"What do you think?"

“Uh~~”

Zhang Minghao hesitated for a moment, then said, "I don't think the other two are a good fit." He quickly added, "That's just my personal opinion, and it might not be right!"

Chen Shuai was slightly downcast, but still said, "One is fine, one is fine..."

"Magnetic correlation, right?"

He said this and went out the door.

Zhang Minghao pursed his lips and looked at Chen Lanjun. Chen Lanjun shrugged and offered an explanation for her mentor, "Professor Chen has been under a lot of work pressure lately."

"Right."

Zhang Minghao sat down again, no longer wanting to study the problem. He opened his phone and scrolled through his messages, suddenly noticing a new email.

Upon clicking, it turned out to be an invitation to a computational mathematics conference?

He looked closely and saw that it was a computational mathematics conference held by the Capital University, inviting him to give a research report.

"A conference on computational mathematics, they invited me?"

"Is the special doctoral report related to the paper published in the Journal of Applied Mathematics?"

Zhang Minghao pondered.

On the other side, Chen Shuai left the doctoral student's workspace and returned to his office, still with a smile on his face.

I've been under a lot of work pressure lately.

In the laboratory, there was a pervasive distrust of him, but with Zhang Minghao, he felt an absolute trust.

Zhang Minghao is different too.

The current research method is based on Zhang Minghao's suggestion. His trust alone is equivalent to that of several or even dozens of other people.

He couldn't resist going to the main office and sharing the news that Zhang Minghao had trusted him with Zhu Bingkun and Xue Kun.

Zhang Minghao said he believes in the existence of magnetic correlations!

"I also think that magnetic correlation is the most likely possibility, as for the other two..."

Chen Shuai hesitated for a moment, then continued, "These are all data analysis results, and they're not definitive. If it doesn't work, I think we should focus our efforts on verifying the magnetic correlation!"

The three of them discussed it for a few minutes.

Xue Kun simply called Zhang Minghao over. Zhang Minghao came to the office and confirmed his opinion: "I believe that the magnetic correlation exists."

"Of the three types of correlations, static magnetic correlation is the most likely to exist, and I would like to study the underlying principles as well."

"If we can theoretically analyze the reasons for the existence of the correlation, we can find a breakthrough and then compare it with other data to find more correlations..."

Zhu Bingkun, Xue Kun, and Chen Shuai exchanged glances and remained silent.

This falls under the realm of theoretical physics and is beyond their capabilities.

Just then, there was a knock on the door.

Meng Guoqing stood at the door and called out, "Excuse me, I'm looking for Zhang Minghao!"

"Professor Meng! Please come in!"

Zhu Bingkun immediately welcomed Meng Guoqing in.

Meng Guoqing went straight to the point as he entered, asking Zhang Minghao, "Have you received the invitation to next week's computational mathematics conference?"

Zhang Minghao nodded and said, "There is one, it says it's an invitation for me to give a report."

"I came to tell you this."

Meng Guoqing laughed and said, "We'll go together then. I'll attend the meeting too, along with Xue Fengzhu and Professor Huang Ming."

Zhang Minghao hesitated for a moment, then said with difficulty, "This... is it okay if I don't go?"

He explained, "I'm a PhD student in physics. It's not really my area of ​​expertise to attend a conference on computational mathematics, is it?"

"Besides, I don't really want to go."

Meng Guoqing's face stiffened.

Xue Kun immediately offered his opinion, "You can decline the student council invitation, right? Just find an excuse to turn it down."

Zhu Bingkun chimed in, "Professor Meng, Zhang Minghao doesn't want to go. You can't lead your student astray!"

"How did it veer off course?"

Meng Guoqing was immediately dissatisfied. He stood up and retorted, "This is an international conference hosted by Capital University. The conference only invited three doctoral students to give presentations, and Zhang Minghao is one of them."

"What's wrong with a physics PhD student? A physics PhD student being invited to a mathematics conference proves their excellence!"

"but……"

"No buts! Zhang Minghao has such a talent for mathematics, you can't let experiments hold him back!"

“Going to study mathematics would be a waste of time; you can’t lead your child down a dead end…”
