Chapter 359: Giving the juniors a heavy blow

"Hoo~"

After reading the paper, Yang Yang Hongbin and Jia Jia Wenyu look at each other, their throats moving. He asks in confusion, "Is this thing really submitted to our journal?"

This content could have been submitted directly to a top journal.

"Should we call Old Zhang and ask?"

Jia Jia Wenyu thinks for a moment, smiles lightly, and shakes his head. "With Old Zhang's rigor, would a mistake in submitting a paper occur? Besides, after years of development, we aren't weak now either."

"That's true."

Yang Yang Hongbin agrees deeply.

Jia Jia Wenyu looks at the paper again and continues, "Then let's look at the other two papers. If there's no problem, let's put this paper in this month's issue."

"Good."

Not long after, the two finish reading the remaining two papers.

"Standard and steady. Compared to Xu Xu Qingzhou's paper... they can't be compared; after all, they aren't on the same level. However, written by an undergraduate, it's still not bad."

"Right, there aren't many places that need modification. It seems Old Zhang is very strict."

"The field of graphics and contact mechanics will probably be lively this month. Using Xu Xu Qingzhou's model, many previous problems will be solved easily."

"There's another problem. Isn't Xu Xu Qingzhou doing that harmonic analysis or something? How did he suddenly run into our computer field?"

"God knows."

"The most outrageous thing is that he really came up with an amazing model."

The sweltering summer passed in busyness.

In October, the temperature dropped significantly. Morning and evening, one has to wear a jacket or a slightly thicker hoodie.

Sunlight shines in through the floor-to-ceiling glass, falling into a corner of the living room. Er Miao hangs its head, dozing in the sun.

Xu Xu Qingzhou lies lazily on the sofa, watching Song Yao read. "Do you have a feeling that summer was stolen?"

"No," Song Yao answers.

"I do." Xu Xu Qingzhou adjusts his posture, staring at the ceiling in a daze. "It's like winter just left, and the next year's winter is here again."

"It must be because our days are too standard."

"Then what do you want?"

"We can do something more exciting."

Song Yao ignores this guy. Getting beaten every day, isn't that exciting enough?

Xu Xu Qingzhou stares at the ceiling and sighs. Time is something that, when you don't pay attention, you don't even know when it slipped away.

Song Yao gets up, stuffs the materials into her bag, ruffles Xu Xu Qingzhou's hair again, and says, "I'm going to eat with Zhang Qiong and the others at noon... When are you going to get a haircut?"

His hair is long, and it doesn't have that prickly feeling when touched anymore.

"The hottest summer has passed."

Xu Xu Qingzhou mutters. Absolutely can't cut it, otherwise, this girl will come over to ruffle it whenever she has nothing to do.

The two pack their things and go out at 8:30. Song Yao goes to Li Daiyue's side, and Xu Xu Qingzhou finds an empty classroom, takes out the manuscript paper, and stares at it in a daze.

Currently, he still can't solve the coupling problem of the two models.

After thinking for half an hour, Xu Xu Qingzhou lets out a long breath, rests his chin on his hand, and relaxes his brain.

A cross-breeze blows in, and the white gauze curtains flutter with the wind. The wind even carries a faint scent of osmanthus. The curtains fall slowly again, returning to their original state.

Xu Xu Qingzhou squints, and two words inexplicably pop into his mind—topology.

Topological structure refers to a mathematical structure that studies the shape and deformation of space without considering metrics and distance.

For multi-particle systems, entangled states may present complex topological structures. These structures may include chain entanglement, ring entanglement, network entanglement, etc., describing the complex and diverse interaction relationships between particles.

In some cases, even if the entangled state is disturbed by the external environment or noise, its topological structure remains unchanged, thereby ensuring the stability and anti-noise capability of the entangled state.

Furthermore, the non-locality of multi-body entanglement is also closely related to topological structure. In an entangled state, the correlation between particles can span the boundaries of time and space; this non-locality can be described and understood using topological structure.

Seems like there's a lot to work with.

Xu Xu Qingzhou digs the manuscript paper out of his bag again.

In manifold theory, a topological structure can be represented as an (n)-dimensional manifold (m), which is a space locally homeomorphic to an (n)-dimensional Euclidean space.

One can obtain the content of entanglement entropy by calculating the topological invariants of the manifold (such as Euler characteristic, genus, etc.).

Lines of complex operators appear on the manuscript paper.

【\psi(x_1, x_2,..., x_n) \neq \psi_1(x_1)\psi_2(x_2)... \psi_n(x_n)】

Topological phase is a physical quantity describing the phase change of particles as they move in space; it is closely related to the topological structure of the system. In multi-body entanglement, the non-locality of particles can be obtained by calculating their topological phase, which helps in understanding the stability and anti-noise capability of the entangled state. Time passes extremely quickly.

Xu Xu Qingzhou is immersed in calculations when he suddenly notices that there seem to be more people around than just a moment ago.

Next door, two boys are discussing math problems in low voices.

"We need to find all positive integer pairs (x, y) satisfying (x+y)(x-y)=n. This can be achieved by traversing all factor pairs of n."

"."

"Here we also have to check whether x and y are both positive integers..."

Through the conversation between the two, Xu Xu Qingzhou knows this is a classic problem of solving positive integers under specific conditions in number theory and combinatorics in the Olympiad.

It's like this when you first enter school; you like to discuss Olympiad problems. By the second semester, you won't, because you will find that these problems are just like that.

There are more and more people in the classroom, very lively. Xu Xu Qingzhou also packs his things, preparing to change places.

"Little Xu?"

Just as Xu Xu Qingzhou packs up, a familiar voice comes from the side.

In the eyes of others...

"Professor Gu." Xu Xu Qingzhou is a bit surprised; he didn't expect it to be such a coincidence. This session happens to be Gu Gu Zhizhong's mathematical analysis class.

Gu Gu Zhizhong puts his teacup on the table with a smile and says, "You kid, haven't seen you for a while, and you've done another big thing."

"Ah?" Xu Xu Qingzhou looks confused.

"You don't know?"

Gu Gu Zhizhong says with a smile, "IPC, your paper made the cover of *Journal of Software*. Many people came to ask me today."

Xu Xu Qingzhou is surprised: "It was published so quickly..."

"I heard from a professor in the School of Computer Science that your paper could have been submitted to a top journal. Why submit it to *Journal of Software*?"

Xu Xu Qingzhou sighs and says helplessly, "No time to translate, so I just submitted it randomly."

Hearing this, Gu Gu Zhizhong is stunned for a moment, suddenly having the urge to beat someone up. He didn't even want the top journal delivered to his doorstep.

However, to a certain extent, this is also a good thing; he doesn't care that much about fame and fortune.

In the classroom, many people's gazes look over, looking at Xu Xu Qingzhou with a little excitement in their eyes.

"Xu Xu Qingzhou, ah!"

"Has he been here all along? Ah, ah, ah, why didn't I see him just now?!"

"Damn, a big shot is hiding in the corner!"

"Finally saw a live one!"

Most are amazed. Besides these, there seem to be challenges?

Xu Xu Qingzhou looks at a girl in the front, short hair, staring tightly at him. Even from ten meters away, he can feel the meaning of "challenge."

This little junior, interesting.

On this side, Gu Gu Zhizhong smiles and asks, "Aren't you doing physics? How did you run into the computer field again?"

"Just doing a friend a favor, tinkered with it randomly."

"Do you kid know that you've created something that shocked the field of graphics and contact mechanics? This is 'tinkered with it randomly'?"

Gu Gu Zhizhong glares, saying with annoyance.

"I'm just being humble," Xu Xu Qingzhou says with a grin.

"Excessive humility is pride." Although Gu Gu Zhizhong says this, his eyes are full of praise. He pauses and asks again: "How is the progress on the physics side?"

"Not very smooth," Xu Xu Qingzhou says truthfully.

"In scientific research, how can it always be smooth sailing? Don't get stuck in a dead end. If the obstacles are relatively large, put it aside first and study it slowly when the opportunity is ripe."

"I will pay attention."

Xu Xu Qingzhou nods. Seeing that the time is almost up, he says, "Professor, if you want to teach, I'll first..."

"No rush."

Gu Gu Zhizhong waves his hand and says with a smile, "I left a problem when class ended last week. I estimate no one has solved it. You happen to be here, why don't you explain it?"

*There it is. * Professor Gu hasn't changed; he likes to give new students a heavy blow first.

This is wanting to use him to shave off the sharpness of this group of juniors.

Just like this "battle-ready" little junior in front.
