Professor Klaas hurriedly called the head of the physics department at Cornell University and said that he needed to be recognized, and this recognition had to be from his own school, otherwise the recognition would be much lower and his self-confidence would be damaged.

"Director!"

"I'm Klaas. Professor Klaas made a phone call and said seriously, "I met Xu Mang at New York University... He is related to Professor Tong of NYU, and now Xu is solving the problems we are having with NYU. ”

"What?"

"Is there such a thing?" the other party was stunned for a moment, with a hint of incredulity in his words, but more excited, and said: "Isn't that great? ”

Klaas smiled bitterly, it seems that the director doesn't know some of the things inside, too... I didn't say anything to him myself, and then squeaked and whimpered: "Director... Xu told us that it was a problem with the physics experiment that prevented NYU from doing the calculations. ”

The protocol?

How could this go wrong!

Hearing Klaas's words, the other party subconsciously denied it, about the experimental part... It was the result of the joint efforts of the physics department at Cornell University, but Xu Mang, the god of contemporary physics, told him that the experiment was problematic...

"Impossible!"

"It's the result of a joint discussion, and there can't be a problem. The head of the physics department at Cornell University said solemnly: "We have also found a lot of such experts, and they basically agree with our experimental procedures. Are we all wrong?"

Not to mention...

At this moment, the head of the physics department is a little uncertain, if the other party is just an ordinary person who is not famous, it must be that there is something wrong with the other party, but the other party is Xu Mang... The question is huge, and he has not missed it to this day, and all his theories have been verified.

Quite possibly... Cornell University and the experts have made a mistake in one of their cognitions, but... It seems a little difficult for everyone to make mistakes together.

"How long will he be able to finish?" asked the director.

"About two hours. "I'm sure he'll be able to do it in two hours, but..."

"Wait!"

"Two hours?" the head of the physics department at Cornell University reflected and hurriedly asked, "Isn't that right... Since there is a problem with the experimental procedure, it is necessary to re-run the experiment, and this experiment is not simple, let alone two hours... It was difficult for both days!"

"That was my second shock. ”

"In the words of Professor Martin of New York University, he told us... Xu Mang uses existing data for analysis, and then derives the answer. Professor Klaas smiled wryly, "I think it's a little ridiculous, how can anyone do this." ”

Perhaps...

It is precisely because he is Xu Mang that he can do it.

"Wait!"

"Tell me the results in two hours!" said the dean of physics at Cornell University, earnestly, "Actually, I don't believe it, how can this be done?"

...

At this point,

Xu Mang was holding a pen, constantly stopping to write on the paper, occasionally using the computer to look at a model made by himself on the screen, in fact, this experiment is quite interesting, it reveals a possible existence of a three-dimensional quantum spin liquid.

Of course, it is only possible to exist... Because there is currently no known way to prove the existence of three-dimensional quantum spin liquids in the world, research experiments at Cornell University and New York University have shown that cerium zirconium pyrochlorate single crystals are suitable materials that can be used as the first three-dimensional version of the long-term search for the state of matter.

A quantum spin liquid is a solid material in which the peculiar properties of quantum mechanics ensure a liquid-like magnetic state.

Regarding the views of Cornell University and New York University, Xu Mang basically agrees that he has also done related research in the past, not three-dimensional quantum spin liquids, but meson spin relaxation experiments, but the concept of this experiment is basically consistent with the three-dimensional quantum spin liquid experiment.

In quantum spin liquids... There is something that cannot be seen in the definition, that is, in the arrangement of rotations, the order of the long range is not seen, how to solve it ... Cerium zirconium pyrochlorate single crystal gives the answer.

Xu Mang put down the pen in his hand, held the mouse and looked at the three-dimensional model on the screen carefully, constantly changing the color of the single crystal, and after trying a few times, he started his own calculations, Cornell University and New York University were right on this problem.

Single-crystal is a material that does not phase change at fifty Kelvin, has no disorder, no long-range magnetic sequence, and no oxygen vacancies or other known defects.

But...

When a single crystal is scattered with inelastic neutrons, it shows the presence of a spin-excited continuum.

Cornell University and New York University believe that this may be a quantum spin liquid, and this idea... Xu Mang basically agrees, but in the latter conclusion, Xu Mang thinks that there is a slight doubt, since the experiment has produced a spin-excited continuum, indicating that there is a spin entanglement that produces a short-range order.

But it can't be fully stated that it is a spin liquid, for the simple reason that quantum spin liquid is defined as a state that exists at absolute zero degrees and cannot be reached by any experiment.

Here we go,

Xu Mang took out his housekeeping skills, and a formula named after his son appeared-Xu Yang structure formula, and now Xu Mang needs to calculate the direction of the electron spin, what does the direction of the electron spin look like in the magnetic electron solid.

Ten minutes later,

The concept of topology was reintroduced to determine what exactly that spin is doing in a solid with a periodic spin arrangement, and at this point... It has been proven that the Cornell and NYU experiments have huge flaws.

Of course

Xu Mang wants to remove the Xu Yang structure formula, and he can't give the Xu Yang structure formula to the United States for no reason because there is a cousin in this team, otherwise he will lose a lot of money, and in the process of going to the Xu Yang structure formula, Xu Mang will collapse a little, which is equivalent to doing it all over again.

No way...

Xu Yang's structural formula is too important, and if it is published, it will lose its superiority over the United States.

Ten minutes later,

Basically, the modification of the experimental part has been completed, and all that remains is to recalculate, take a look at the time, more than half an hour has passed, and then Xu Mang turned on his own acceleration mode, and he needs to solve everything in twenty minutes.

meanwhile

In another office,

My cousin, Professor Martin, Professor Klaas, and a few international students were anxiously waiting, and now more than half an hour had passed, and although there was still plenty of time, the longing could not be stopped.

"Martin?"

"I think... Our experiments didn't go wrong. Professor Klaas was not dead yet, he always believed that he was right, and then said: "I have contacted the head of the physics department at Cornell University before, and he also thinks that the experimental part cannot be wrong. ”

"Humph!"

"Are you questioning the remarks of the world's top physicists?" the cousin glanced at Klaas and said indifferently: "Don't do any more fearless struggles, your Cornell University physics department just can't do it, what else do you need to justify?"

"You..."

Professor Klaas was so angry in his heart, how could he have been insulted like this before, there was no way... The pressure Xu Mang gave was too great, so big that he couldn't breathe, but it also brought infinite hope, if... What if Xu Mang is wrong? Although this hope is very slim.

"Stop struggling fearlessly. ”

"There's no way my cousin-in-law could go wrong. My cousin laughed.

Looking at Klaas's aggrieved expression, my cousin and the members of her team felt comfortable in their hearts... The previous appearance was high, but at this time, his face was full of bitter melon.

Then

Professor Klaas received a phone call from the chair of the physics department at Cornell University.

"Hello?"

"Director!"

"Is there anything going on?" asked Professor Klaas.

"Regarding the problem of the error of the experimental procedure you mentioned earlier, we at Cornell University Physics Department have re-researched and discussed it, and we think... There was no problem with the experiment at all!" the other party's attitude was very tough and full of confidence.

"Is there no problem?"

Professor Klaas's neck also stiffened a lot, and his previous depressed state was swept away, and he glanced at his cousin and said indifferently: "It's a pity that some people don't think so." ”

"Then it depends on the final result!"

"But I can tell you now that it's NYU's own problem!"

afterwards

hung up the phone,

Professor Klaas said to Martin and his cousin, who were present, "It's a pity... We, the physics department at Cornell University, have come to the conclusion that there is no problem with the experimental procedure at all, even if Xu Mang comes... Nor can it change this fact. ”

Arrogant!

Dig wildly!

Ignorance!

The cousin glanced at the middle-aged man who had never been at odds with him, showed a contemptuous smile, and said, "That's the conclusion? Premature conclusions will be slapped in the face, Professor Klaas... Which is more internationally known, the Xu Yang Institute or the Department of Physics at Cornell University?"

"I think..."

This question does not need to be answered. My cousin smiled, "In less than an hour and a half, we will know the final answer." ”

Words fall,

He no longer bothered with the self-righteous Klaas.

...

About twenty minutes more,

Xu Mang stretched his waist, he hadn't worked at such a high intensity for a long time, and he was as tired as if he had fallen apart in an instant, and he was old... I'm really old, if I was myself five years ago, let alone twenty minutes, twenty hours, there would be no pressure.

rise

Leave the office,

Xu Mang took the data in his hand, went to the office next door, knocked on the door, and then pushed the door in.

"Huh?"

"Are they all there?"

"It's been solved!" Xu Mang said with a smile: "It's so fast!"

“？？？”

“？？？”

“？？？”

Seeing Xu Mang's smiling face, everyone's facial features were almost distorted together.

What the?

This... It's been less than an hour!
