I really don't want to lie down and win

"Maybe this is love." Xu Mang squeezed Xiaoman's face, and said seriously, "Have you taken care of your charity foundation seriously?"

"Yes!"

"I almost forgot... I haven't taken care of it for a long time." Yang Xiaoman suddenly reacted, and said seriously: "Find an opportunity to check the accounts. The number of reports in the past three months is a bit too much. , besides various supplies and donations, the other two months... are much more than before."

"Ah."

"You'd better check it out." Xu Mang said calmly, "Don't give out 100 for [-] million."

Yang Xiaoman nodded, and said silently: "If this happens... I will be the first to take the life of the responsible person!"

...

institute of physics,

Subordinate Quantum Materials and Physics Research Group.

Dr. Gu and his team are solving a problem.

In many materials, resistance and voltage change in the presence of a magnetic field, often smoothly as the field rotates. This simple magnetic response is the basis for many applications, including non-contact current sensing, motion sensing, and data storage. .

In crystals, the charge and spin arrangement and interaction of electrons underlie these effects, and exploiting this arrangement property, known as symmetry, is a key factor in the design of functional materials for spintronics.

Dr. Gu needed to find a new type of magnetically driven electrical response.

however,

Now they are in trouble. This trouble is very complicated. At present, Professor Gu and his team cannot solve it.

I found a lot of people,

But basically there is nothing they can do, and those who are capable have no time.

"Professor Gu?"

"What do we do now?" asked a young researcher.

How to do?

who knows what to do...

Professor Gu is also very helpless. According to theoretical reality, crystals composed of cerium, aluminum, germanium and silicon can produce a new type of magnetically driven electrical response, but experiments have found that it is impossible.

"We must find an authority in this area." Professor Gu said seriously: "In the field of materials and physics, only authoritative figures can help us."

Material?

physics?

authority?

The few people present were stunned for a moment, and based on the elements of these people, they pieced together and sorted out a formula.

Academician Xu, an authority on materials physics

"Academician Xu!"

"It's difficult to find Academician Xu!"

......

8 Chapter Fifty This Is Strength (2/2)

Although the current Xu Yang Research Institute is quite small, although the sparrow is small and well-equipped with all kinds of equipment, in fact, the area is quite large. Compared with the Academy of Sciences, it is not worth mentioning at all. Fortunately, the equipment than others.

With Xiaoman as a powerful mogul, he can handle any equipment, and if there is something that cannot be handled without money, if there is... Let Xu Mang threaten to sell it, and he may be retaliated against.

The research on superfluid helium is not a particularly complicated research. Xu Mang only got inspiration from a paper and obtained some results through theoretical calculations. Of course, experiments are still needed to prove it.

really,

Xu Mang's initial calculation results were problematic. At first he thought that when the temperature was lowered, the half-quantum vortex would disappear, but according to experiments, it was found that when the superfluid helium was cooled to a certain temperature, the half-quantum vortex still existed, and at this time it appeared non-topological walls.

Although physical walls would not impede flow, non-topological walls would change the magnetism of helium, which is similar to what Xu Mang envisioned, just like what happens when a superfluid in a nanostructured volume cools.

To Xu Mang's surprise, he also discovered the second speed of sound in the Bose-Einstein condensate. This is a quantum phenomenon. In addition to the normal sound of liquid, there is a second speed in superfluid helium sound phenomenon.

This phenomenon stems from the quantum nature of the liquid, where the first sound is first heard, and then when it appears as the second sound, there is a second chance to hear it, albeit weakly.

Between one and two Kelvin, which are 25 m/s and 250 m/s respectively, although the traditional second-acoustic theory has been successfully applied to superfluid helium, the appearance of Bose-Einstein condensate brings new challenge.

Therefore, Xu Mang proposed a brand new theory to capture the second sound in these quantum liquids. This was entirely due to Xu Mang's discovery that in superfluid helium, the speed of the second sound was faster, so he proposed the Feynman path integral to Extended superfluid theory.

Feynman's path integral theory expressed quantum mechanics as the sum of trajectories, and Xu Mang modified these trajectories. In the old path integrals, they contained the information of quantum fluctuations, extending from A to B, which is a Trajectories integrated over the incoming path are visualized while the cross-section is more or less circular with a constant diameter along the length.

But in the new path integral, the shape of the cross section can be changed, it can be in the shape of an ellipse, and Xu Mang called these quantum mechanical states squeezed states, so it can be applied to any method based on path integrals.

"Ugh..."

"I don't know if it can be adopted." Xu Mang sighed. He wanted to use this method to solve many phenomena at the interface between quantum physics and classical physics. Although there were not many solutions, this new framework was used. In the end, many problems will be able to gain insights from their nature.

Anyway,

Xu Mang used superfluid helium to draw out two points of view, a new quantum structure in superfluid helium, and a brand new superfluid theory.

But Xu Mang is very worried now that these super-powerful theories may not be accepted by the world. After all, they are too far ahead, especially the new superfluid theory behind it, which will definitely usher in many people's scolding. Of course, these people should It's from Europe and America.

For example, the BBC or CNN, or a low-quality newspaper like the New York Times, to Xu Mang, whether it was the BBC, CNN, the New York Times, or any other mess, they were all psychopaths who liked to smear.

I can't understand the thinking of these people. Perhaps for them, the main reason is that Huaguo or itself has a little bit of turmoil, which is to oppose them, but think about it carefully... This is the usual European and American routine, using contradictions to solve contradictions.

leave the lab,

Xu Mang returned to his office, crossing his legs and looking like a fool. He didn't have the slightest majesty of an academician, leaving only a faint smell of salted fish, revealing a trace of decadence.

bang bang bang,

There was a knock on the door,

Immediately afterwards, Wang Ai came to the door with a stack of documents. For the daughter of his former mentor, Xu Mang had to say that he took good care of her, and Wang Ai lived up to Xu Mang's expectations. It has grown a lot and published many heavyweight research reports.

pity...

I don't even come to visit during the Chinese New Year. Logically speaking, I am her leader, brother, and teacher.

"Academician Xu."

"This is the most mysterious gravitational wave that we have detected recently." Wang Ai submitted one document, and then submitted the second one, and said seriously: "This is the violent gravitational wave that we simulated through the simulation map." Just before the explosion, the star was stretched by tidal forces."
