I really don't want to lie down and win

words fell,

The presence fell into silence, only relying on the existing data, and then correcting the experimental errors?

What kind of ability is this?

but,

Here comes the problem!

Since there is an error in the experimental part, this problem...needs to be studied carefully.

"Ha ha!"

"Unexpected!"

"It turns out that the problem lies with Cornell University." The cousin glanced at Professor Klass, and said calmly: "Cornell University...is really not good at physics!"

Hearing what my cousin said,

Professor Klass almost didn't go crazy, and hurriedly argued: "Impossible...we won't make mistakes!"

"is it?"

"Then what do you mean, my brother-in-law is wrong?" The cousin said calmly, "We'll see the result in two hours."

Professor Klass left the office and picked up the data again. After careful analysis and investigation, he found no problems... At this moment, he was completely confused. There was nothing wrong with it. Why did Xu Mang say that the steps were wrong? up?

"No!"

"impossible!"

"How could this go wrong?"

......

The first thousand and 120 six chapters are so fast!

Professor Klass hurriedly called the dean of the Department of Physics at Cornell University. He needed to be recognized by others, and the recognition had better be from his own school, otherwise the degree of recognition would be greatly reduced, and his self-confidence would also 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 of New York University, and now Xu Mang is solving our problem. and the problems that NYU is having."

"what?"

"Is there such a thing?" The other party was stunned for a moment, with a hint of disbelief in his words, but more excitement, and said: "Isn't that very good? This problem will be solved soon, and by the way, I also got in touch with Xu It lays the foundation for future cooperation.”

Klass smiled wryly. It seems that the director didn't know about some of the things inside, and also...he didn't tell him, and then he said, "Director...Xu Mang told us that it's a physics experiment. Something went wrong with the procedure, preventing NYU from doing the calculation."

Experimental procedure?

How could this go wrong!

Hearing what Klass said, the other party subconsciously denied it. The part about the experiment... was the result of the joint efforts of the Department of Physics at Cornell University. However, Xu Mang, the contemporary god of physics, told him that there was something wrong with the experiment...

"impossible!"

"This is the result of a joint discussion, and there is no possibility that there will be 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?"

let alone...

At this moment, the head of the physics department is a little uncertain. If the other party is just an ordinary unknown person, there must be something wrong with the other party, but the other party is Xu Mang... This is a big problem, and he hasn't solved it yet. Miss it, and his whole theory is validated.

It is very possible that ... Cornell University and those experts have made a mistake in one cognition, but ... everyone makes mistakes together, which seems to be difficult.

"How soon will he finish?" asked the Director.

"About two hours." Klass said, "I believe he can finish it within two hours, but..."

"and many more!"

"Two hours?" The dean of the Department of Physics at Cornell University realized this, and asked hastily: "No...Since there is a problem with the experimental procedure, the experiment needs to be repeated, and this experiment is not simple, let alone Two hours... two days were difficult!"

"That was my second shock."

"According to Professor Martin of New York University, he told us...Xu Mang can use the existing data to analyze, and then get the answer through derivation." Professor Klass smiled wryly: "I think this is a little ridiculous, how is it possible? Someone did it."

maybe...

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

"Wait!"

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

...

at this time,

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

Of course, it is only possible...Because there is no known method in the world to prove the existence of three-dimensional quantum spin liquids, and research experiments at Cornell University and New York University have shown that cerium-zirconium pyrochlorate single crystals are The right material could serve as the first three-dimensional version of the long-sought state of matter.

A quantum spin liquid is a solid material in which quantum mechanical peculiarities ensure a liquid-like magnetic state.

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

In the quantum spin liquid... there is something that cannot be seen in the definition, that is, in the arrangement of the spin, the long-range order cannot be seen. How to solve it... The single crystal of cerium zirconium pyrochlorate gave the answer.

Xu Mang put down the pen in his hand, held the mouse and carefully looked at the [-]D model on the screen, constantly changing the color of the single crystal, and after a few attempts, he started his own calculations again. Right on the subject.

A single crystal is a material that does not undergo phase transitions below [-] Kelvin. There is no disorder in the crystal, no long-range magnetic order, and no oxygen vacancies or other known defects.

but...

When single crystals are subjected to inelastic neutron scattering, a spin excitation continuum is shown to exist.

Cornell University and New York University believe that this may be a quantum spin liquid. This view...Xu Mang basically agrees, but Xu Mang thinks there is a little bit of doubt in the latter conclusion. Since the experiment produced a spin excitation continuous body, suggesting the existence of spin entanglement that produces short-range order.

But it cannot be fully explained that it is a spin liquid. The reason is very simple. The definition of a quantum spin liquid is a state existing at absolute zero, which cannot be reached by any experiment.

here,

Xu Mang showed his housekeeping skills, and a formula named after his son appeared. Xu Yang's structural formula. Now Xu Mang needs to calculate the direction of electron spin. In the magnetic solid state of electrons, the direction of electron spin is Exactly what it's like.

10 minutes later,

Reintroduce the concept of topology to determine what the spin is doing in a solid with a periodic spin arrangement, and at this point... it has been proved that there are huge flaws in the experiments of Cornell University and New York University .
