Chapter 1125

Professor Klass called the head of the Physics Department of Cornell University in a hurry. He needed to be recognized by others, and the recognition had better be from his own school. Otherwise, the recognition would be greatly reduced and his self-confidence would be damaged.

"Director!"

"I'm Klass." Professor Klass called each other and said seriously, "I met Xu mang at NYU... He is related to Professor Tong of NYU. Now Xu mang is solving the problems we have with NYU."

"What?"

"And something like that?" The other party was stunned for a moment, and his words were inconceivable, but more excited, he said: "that's not very good? This problem will soon be solved, and Xu mang was contacted by the way, laying a foundation for future cooperation. "

Klass grinned bitterly. It seems that the director didn't know something about it. He didn't say it to him. Then he said, "director... Xu mang told us that there was something wrong with the steps of physics experiment, which made New York University unable to calculate."

Experimental steps?

How can this go wrong!

Hearing Klass's words, the other party subconsciously denied that the part about the experiment was the result of the joint efforts of the Physics Department of Cornell University. However, Xu Mang, the God of contemporary physics, told him that there was something wrong with the experiment...

"impossible!"

"This is the result of the discussion together. There is no possibility of problems." Cornell University Physics Department Director seriously said: "we also have a lot of such experts, basically agree with our experimental steps, is not... All of us are wrong?"

Let alone...

at the moment, the head of the Department of physics has some uncertainties. If the other party is just an ordinary and unknown person, there must be something wrong with the other party, but the other party is Xu mang... This problem is very big, he has not missed it up to now, and all his theories have been verified.

It's very likely that... Cornell University and the experts have made a mistake in a certain cognition, but... It seems difficult to make mistakes together.

"How soon can he finish it?" Asked the director.

"In about two hours." "I believe he can do it in two hours, but..."

"wait a minute!" Klass said

"Two hours?" The director of the Department of physics at Cornell University reflected this and asked in a hurry: "no... since there is a problem with the experimental steps, we need to carry out the experiment again, and this experiment is not simple, let alone two hours... Two days are very difficult!"

"This is my second shock."

"According to Professor Martin of New York University, he told us... Xu mang uses the existing data to analyze, and then deduces the answer." Professor Klass said with a wry smile, "I think it's a bit ridiculous. How can anyone do it?"

Maybe...

because he is Xu Mang, he can do it.

"Wait!"

"Tell me the result in two hours!" "In fact, I don't believe it. How can it be done?" said Cornell's physics director

...

at this time,

at this time,

Xu mangzheng kept writing on the paper. Occasionally, he used a computer to look at a model made by himself on the screen. In fact, this experiment is very interesting. It reveals a possible three-dimensional quantum spin liquid.

Of course, it is only possible... Because there is no known method to prove the existence of three-dimensional quantum spin liquid in the world, and the research and experiment of Cornell University and New York University show that cerium zirconium pyrochlorate single crystal is a suitable material, which can be used as the first three-dimensional version of the long-term search for the state of matter.

Quantum spin liquid is a kind of solid material, in which the peculiar properties of quantum mechanics ensure the liquid like magnetic state.

With regard to the views of Cornell University and New York University, Xu mang basically agrees. He has done relevant research in the past. It is not a three-dimensional quantum spin liquid, but a meson spin relaxation experiment. However, the concept of this experiment is basically consistent with the three-dimensional quantum spin liquid experiment.

In the quantum spin liquid... There is an invisible thing in the definition, that is, in the rotation arrangement, there is no long-range order, how to solve... Cerium zirconium pyrochlorate single crystal gives the answer.

Xu put down his pen in his hand, held the mouse and looked at the three-dimensional model on the screen carefully. He was constantly changing the color of the single crystal. After several attempts, he started his own calculation. Cornell University and New York University are right on this issue.

Single crystals are materials that do not phase change below 50 Kelvin. There is no disorder, no long-range magnetic order, and no oxygen vacancies or other known defects.

However...

when the single crystal undergoes inelastic neutron scattering, it will show the existence of spin excited continuum.

Cornell University and New York University believe that this may be a quantum spin liquid, which Xu basically agrees with. However, Xu believes that there is a little doubt about the latter conclusion. Since the experiment produces a spin excited continuum, it indicates that there is a short-range ordered spin entanglement.However, it can not be completely explained that it is a spin liquid. The reason is very simple. The definition of quantum spin liquid is a state existing in absolute zero degree, which can not be reached by any experiment.

At this point,

Xu mang has taken out his own skills and launched a formula named after his son - Xu Yang structure formula. Now Xu mang needs to calculate the direction of electron spin, what is the direction of electron spin in magnetic electronic solid state.

Ten minutes later,

the concept of topology was reintroduced to determine what the spin was doing in solids with periodic spin arrangements, and at this point... It has been proved that Cornell University and New York University experiments have great defects.

Of course,

if Xu mang wants to get rid of Xu Yang's structural formula, he can't send it to the United States for no reason because there is a cousin in the team. Otherwise, it will be a big loss. In the process of formulating Xu Yang's structure, Xu mang will collapse a little, which is waiting to be repeated.

There is no way...

Xu Yang's structural formula is too important. If this is published, it will lose its superiority to the United States of America.

Ten minutes later,

basically, the modification of the experimental part has been completed, and the rest is to recalculate. After a look at the time, it has been more than half an hour. Then Xu mang opened his own acceleration mode. He needs to solve all problems in 20 minutes.

At the same time,

in another office,

cousin, Professor Martin, Professor Klass and several foreign students are waiting anxiously. Now more than half an hour has passed. Although there is plenty of time, the desire can not be stopped.

"Martin?"

"I don't think... Our experiment was wrong." Professor Klass did not give up. He always thought he was right, and then said, "I have contacted the head of Physics Department of Cornell University before, and he also thinks that the experiment part can't be wrong."

"Hum!"

"Are you questioning the statements of the world's top physicists?" My cousin glanced at Klass and said calmly, "don't struggle fearlessly any more. You can't do it in the Department of physics at Cornell University. What else do you need to explain?"

"You..."

Professor Klass was angry. How could he have been insulted like this before? There was no way... Xu Mang's pressure was too great to breathe, but it also brought infinite hope. What if Xu mang was wrong? Although this hope is very slim.

"Stop fighting fearlessly."

"My cousin's husband can never be wrong." My cousin said with a smile.

Looking at Klass's expression, my cousin and her team members, I feel comfortable... The way I was high before, but now I'm full of bitter gourd.

At this time,

Professor Klass received a phone call from the head of the Department of physics at Cornell University.

"Hello?"

"Director!"

"What's the matter?" Asked Professor Klass.

"As for the problem that you said that the experimental steps were wrong, we conducted a new research and discussion in the Department of physics of Cornell University. We believe that... There is no problem in the experiment at all!" The other side's attitude is very tough, full of confidence.

"No problem?"

Professor Klass's neck is also a lot of hard, before that depressed state swept away, looked at his cousin, calmly said: "unfortunately, some people don't think so."

"It depends on the final result!"

"But I can tell you now, it's NYU's own problem!" Said the other.

After that,

hung up the phone,

Professor Klass rushed to Martin and his cousin who were present and said, "it's a pity... Our department of physics at Cornell University has come to the conclusion that there is no problem with the experimental steps, even if Xu mang comes... It can't change this fact."

Arrogance!

Digging!

Ignorance!

My cousin took a look at the middle-aged man who he had never dealt with. She showed a slight smile and said, "is this the conclusion? History tells us that... Premature conclusions will be slapped in the face, Professor Klass... Which one has more international fame, Xu Yang Institute or Cornell University Physics Department? "

"I think..."

"there is no need to answer this question." My cousin said with a smile: "there is still less than an hour and a half before we can know the final answer."

As a result,

he stopped taking care of this self righteous Klass.

...

about 20 minutes more,

Xu mang stretched for a long time. He had not worked at such a high intensity for a long time. In a moment, he was as tired as a frazzle. He was really old. If he had been himself five years ago, let alone 20 minutes or 20 hours, he would have no pressure.After getting up,

leaving 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 to enter.

"Ouch?"

"Are they all there?"

"It's settled!" Xu mang said with a smile: "it's so fast!"

“？？？”

“？？？”

“？？？”

Seeing Xu mang with a smile on his face, his facial features almost twisted together.

What?

This... This is less than an hour!
