Professor Klaas hurriedly called the dean of the physics department at Cornell University. He needed to be recognized by others, and this recognition should preferably be from someone in his own school, otherwise the recognition will be reduced a lot and his self-confidence will be affected.

damage.

"director!"

"I'm Klass." Professor Klass called the other party and said seriously: "I met Xu Mang at New York University... He is related to Professor Tong from New York University, and now Xu Mang is solving our problem

and problems encountered by New York University.”

"What?"

"Is there such a thing?" The other party was stunned for a moment, with a hint of disbelief in his words, but more excited, and said: "Isn't that great? This problem will be solved soon, and by the way, I also got in touch with Xu

It laid the foundation for future cooperation."

Klaas smiled bitterly. It seemed that the director didn't know some of the things inside, and he didn't tell him either. Then he said in a squeaky voice: "Director... Xu Mang told us that it was a physics experiment.

Something went wrong with the procedure, preventing NYU from performing calculations."

Experimental steps?

How could this possibly go wrong!

After hearing what Klaas said, the other party subconsciously denied it. Regarding the experimental part... it was the result of the joint efforts of the Department of Physics at 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 a discussion together, and there is no chance that there will be any problems." The dean of the Department of Physics at Cornell University said seriously: "We have also found many such experts, and they basically agree with our experimental procedures. Could it be...

.are we all wrong?”

Not to mention...

At this moment, the head of the physics department is a little unsure. 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 huge. He has not yet solved it.

Missed, all his theories were verified.

It is very possible that... Cornell University and those experts have made a mistake in a certain understanding, but... it seems a bit difficult for everyone to make mistakes together.

"How long will it take for him to finish?" the director asked.

"About two hours." Klass said: "I believe he can complete it in two hours, but..."

"etc!"

"Two hours?" The dean of the Department of Physics at Cornell University reacted and asked hurriedly: "That's not right... Since there is a problem with the experimental steps, the experiment needs to be rerun, and this experiment is not simple, let alone

Two hours... both days were difficult!”

"That was the second thing that shocked me."

"According to Professor Martin of New York University, he told us...Xu Mang uses existing data to analyze, and then obtains the answer through derivation." Professor Klass smiled bitterly: "I think this is a bit ridiculous, how is it possible?

Someone does this."

Maybe...

Just because he is Xu Mang, he can do it.

"wait!"

"Tell me the results in two hours!" The director of physics at Cornell University said seriously: "Actually, I don't believe it either. How can this be done?"

...

at this time,

Xu Mang was holding a pen and kept writing on the paper. Occasionally he would use the computer and take a look at a model he made on the screen. In fact, this experiment was quite interesting. It revealed the possible existence of a three-dimensional quantum spin liquid.

.

Of course it is only possible... because there is currently no known method in the world to prove the existence of three-dimensional quantum spin liquids, and research experiments by Cornell University and New York University have shown that cerium zirconium pyrochlorate single crystal is

With the right materials, it could serve as the first three-dimensional version of the long-sought state of matter.

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. He has done related research in the past, which is not a three-dimensional quantum spin liquid, but a meson spin relaxation experiment. However, the concept of this experiment is different from

Three-dimensional quantum spin liquid experiments are basically consistent.

In quantum spin liquids... there is something invisible in the definition, that is, in the arrangement of rotation, the long-range order cannot be seen, how to solve... The cerium zirconium pyrochlorate single crystal gave 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. After trying a few times, he started his calculations again. Cornell University and New York University are doing this.

That's right on the issue.

Single crystal materials do not phase change below fifty Kelvin, there is no disorder in the crystal, there is no long-range magnetic order, and there are no oxygen vacancies or other known defects.

but...

When a single crystal undergoes inelastic neutron scattering, it will show the existence of a spin excitation continuum.

Cornell University and New York University believe that this may be a quantum spin liquid. Xu Mang basically agrees with this view. However, Xu Mang thinks there is a trace of doubt about the subsequent conclusion. Since the experiment produced a spin excitation continuum

body, indicating the existence of spin entanglement that produces short-range order.

But it cannot be completely explained that it is a spin liquid. The reason is very simple. The definition of quantum spin liquid is a state that exists at absolute zero, and no experiment can reach this state.

Arrived here,

Xu Mang used his special skills, and a formula named after his son appeared - Xu Yang's structural formula. Now Xu Mang needed to calculate the direction of the electron spin. In the magnetic solid state of electrons, the electron spin

What exactly does the direction look like.

Ten minutes later,

Reintroducing the concept of topology to determine what exactly this spin is doing in a solid with a periodic spin arrangement. At this point...it has been proven that the Cornell University and New York University experiments have huge flaws.

.

certainly,

Xu Mang wants to remove Xu Yang's structural formula. He cannot give Xu Yang's structural formula to the United States for no reason just because there is a cousin in the team. Otherwise, he will be at a loss. In the process of removing Xu Yang's structural formula, let him

Xu Mang collapsed a little, it was like doing it all over again.

no way...

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

Ten minutes later,

Basically, the modifications to the experimental part were completed. All that was left was to recalculate. He glanced at the time and saw that more than half an hour had passed. Then Xu Mang turned on his own acceleration mode. He needed to do it within twenty minutes.

Solve all problems.

at the same time,

in another office,

Cousin, Professor Martin, Professor Klaas and several international students are waiting anxiously. More than half an hour has passed now. Although the time is quite ample, the desire cannot be stopped at all.

"Martin?"

"I think... there is nothing wrong with our experiment." Professor Klass has not given up yet. He always believes that he is correct, and then said: "I have contacted the dean of the Department of Physics at Cornell University before, and he also

I think it’s impossible to go wrong in the experimental part.”

"snort!"

"Are you questioning the remarks of the world's top physicists?" My cousin glanced at Klass and said calmly: "Stop struggling fearlessly. Your Cornell University Physics Department just can't do it. What else needs to be done?"

excuse?"

"you..."

Professor Klass was so angry in his heart. How could he have been insulted like this before? There was no way... The pressure given by Xu Mang was too great, to the point of being unable to breathe, but it also brought unlimited hope. If...

..What if Xu Mang is wrong? Although this hope is slim.

"Stop struggling fearlessly."

"My cousin's husband can never make a mistake." The cousin smiled.

Seeing Klaas's aggrieved expression, my cousin and the members of her team felt so comfortable... They had looked so aloof before, but now their faces were full of bitterness.

At this time,

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

"Hello?"

"director!"

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

"As for the error in the experimental steps you mentioned before, our Department of Physics at Cornell University has re-researched and discussed it. We believe that... there is no problem with the experiment at all!" The other party's attitude was very tough and full of confidence.

"No problem?"

Professor Klaas's neck also stiffened a lot, and the previous depressed state was gone. He glanced at his cousin and said calmly: "It's a pity that some people don't think so."

"Then let's see the final result!"
