I Don’t Want to Win Lying Down

Although the current Xu Yang Institute is quite small, although the sparrow is small and has all the internal organs, it has all the equipment inside. In fact, the area is quite large. Compared with the Academy of Sciences, it is not worth mentioning. Fortunately, the equipment Aspect surpasses others.

With such a powerful trench as Xiaoman, you can handle all the equipment without money. If there is... let Xu Mang threaten it, you may be retaliated if you sell it.

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

really,

Xu Mang’s initial calculation results were problematic. Initially, he believed that when the temperature was lowered, the semi-quantum vortex would disappear, but according to experiments, it was found that when the superfluid helium is cooled to a certain temperature, the semi-quantum vortex still exists, and this time it appears. A non-topological wall surface.

Although physical walls will not hinder the flow, non-topological walls will change the magnetic properties of helium, which is similar to what Xu Mang envisioned, just like what happens when the superfluid in the nanostructured volume cools.

However, Xu Mang was surprised that he also discovered the second speed of sound in the Bose-Einstein condensate. This is a quantum phenomenon. In superfluid helium, in addition to the normal sound of liquid, the second sound Kind of sound phenomenon.

This phenomenon stems from the quantum nature of the liquid. First, the first sound will be heard, and then when it appears as the second sound, there will be a second chance to hear it, even though the sound is very weak.

Between one and two Kelvins, which are 25 meters per second and 250 meters per second, respectively. Although the traditional second sound theory has been successfully applied to superfluid helium, the Bose-Einstein condensate The emergence of has brought new challenges.

Therefore, Xu Mang proposed a new theory to capture the second sound in these quantum liquids. This is entirely due to Xu Mang’s discovery that in superfluid helium, the second sound is faster, and thus proposed Feynman path integrals. Extend superfluid theory.

Feynman’s path integral theory expresses quantum mechanics as the sum of trajectories, and Xu Mang modified these trajectories. In the old path integral, they contain the information of quantum fluctuations, extending from A to B, which is a Visualize the trajectory of the entry path integral, and the cross section is more or less round, with a constant diameter along the length.

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

"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 are not many examples to solve, he uses this new framework. In the future, many questions will be able to get insights in essence.

In short,

Xu Mang used superfluid helium to derive two points of view, the new quantum structure in superfluid helium, and a new theory of superfluid.

But Xu Mang is now very worried that these super-strong theories may not be accepted by the world. After all, there are too many advances. Especially the new super-fluid theories in the back will surely welcome a lot of people's scolding. It's from Europe and America.

For example, BBC or CNN, or inferior newspapers such as the "New York Times", to Xu Mang, whether it is BBC, CNN, or the New York Times, as well as some messy things, they are a group of crazy people who like to smear.

I can't understand the thinking of these people. Perhaps speaking about them, the main Chinese or myself have a little bit of trouble, just to oppose them, but think about it...this is the usual routine of Europe and the United States, using contradictions to resolve contradictions.

Leave the laboratory,

Xu Mang returned to his office, holding Erlang's legs upright, showing no dignity as an academician. Only a touch of salted fish was left, and a trace of decadence was revealed.

Bang bang bang,

There was a knock on the door,

Then Wang Ai came to the door with a stack of documents. Xu Mang had to say that he took good care of her daughter who used to be his teacher, and Wang Ai did not live up to Xu Mang’s expectations. During the time working here, He has grown a lot and published many heavyweight research reports.

unfortunately...

I don’t even come to visit during the New Year. According to the truth, I am her leader, brother, and teacher.

"Academician Xu."

"This is the most mysterious gravitational wave we have detected recently." Wang Ai submitted a document, followed by a second one, and said earnestly: "This is what we have simulated through a simulation diagram that is violent. Immediately before the explosion, the star was stretched by tidal forces."

Xu Mang checked it carefully, raised his head and asked, "You mean this is the merger of two original black holes? In the study of the expansion of super large black holes, the concept of the original black hole was proposed. How come this time? "

"No no no!"

"We have summarized this merger into the neutron star collision." Wang Ai said: "Actually...Academician Xu, the purpose of my coming this time...I want you to help me transfer to another department."

"what?"

"Transfer to another department?" Xu Mang was stunned, and asked curiously: "What? The relationship with other people in the team broke?"

"No."

"I want to challenge physics research in other fields." Wang Ai smiled bitterly: "Astrophysics is not my strong point."

"..."

"Sun Chuanxiao knows?" Xu Mang asked.

Wang Ai nodded and said seriously: "Brother Sun knows that he asked me to discuss with you. If you agree, he is willing to let go. If you disagree...I can only stay in the gravitational wave detection laboratory."

Xu Mang: 囧

This is completely forced!

Forget it...

"Ok!"

"You are also a veteran. Although your qualifications are a little weak, it is difficult to have an opponent in your research ability and results. Then you will work hard and bring some new people." Xu Mang said: "There should be no problems, right? "

"it is good!"

"The task must be completed." Wang Ai said with a smile, "I want to do research on condensed matter physics."

Xu Mang nodded, knowing why Wang Ai chose condensed matter physics, because it is easy to make achievements in this area, which is like theoretical physics.

After Wang Ai left,

Xu Mang called the former head teacher, Professor Wang, and told his daughter about the recent situation. In addition to a few words of gratitude, it is more about the research findings in physics, and the future Xu Yang Institute’s new intern students Requirements.

Due to the change in nature, the requirements have been improved a lot. Previously, it was only for graduate students, but now graduate students are not good enough. Xu Mang requires independent research capabilities. Although it will still be a team model, members still need corresponding research. ability.

"This one..."

"I'm studying for a Ph.D." Xu Mang said: "And it's too bad without..."

"We don't have a few PhDs in the Physics Department in a year. Those who can read Ph.D. are all first-class." Professor Wang smiled bitterly: "Xu Mang...you can't find it anymore."

"That can't be helped..."

"The requirement is such a requirement, forget it... After all, I am their senior brother." Xu Mang said with a smile: "You can be a PhD student, but you must pass the corresponding political review... This is the above requirement. of."

"it is good!"

"I will discuss with Director Fang."

hang up the phone,

Xu Mang stretched his waist, glanced at the pile of documents on his desk, and remembered that he had not yet written a research report.

"let's talk tomorrow."

"Go home and take your wife!"

After packing his handbag, Xu Mang took a pile of documents and planned to go home to Xiaoman's gentle town.

"Tingling bell~"

suddenly,

The landline on the desk rang.

"Hey?"

"Who?" Xu Mang's tone was not very good, after all, it affected the time to go home to hold his wife.

"..."

"Academician Xu... I am Gu Chong, the head of the Quantum Materials and Physics Research Group at the Institute of Physics." After hearing Xu Mang's tone, Professor Gu thought he had disturbed him and said helplessly: "I'm really sorry... . Academician Xu, did I disturb you?"

"what?"

"Oh...no no." Xu Mang asked curiously: "What's the matter?"

"Ahem..."

"Academician Xu...We want you to help us solve a problem." Professor Gu smiled bitterly: "This problem can only be solved by you. It is about the electric response of the magnetic drive. Our theoretical research shows that Crystals composed of germanium and silicon can produce a new type of magnetic drive electrical response."

"But on the experimental part..."

"It's not the result of our theoretical calculations at all. It's a pity...all of our theoretical parts are wrong." Professor Gu said: "After searching many people, I couldn't solve this problem."

"is it?"

"Oh oh oh..." Xu Mang was anxious to go home, without even thinking about it, and said absently: "You can send it to my mailbox first... small questions, small questions..."

Snapped!

Hang up directly.

Professor Gu held the phone with a confused look, this...Is the plot developing too fast? Just asked about the research direction and questions, and then directly agreed...this...should I not ask more?

"professor?"

"What did Academician Xu say?" asked a researcher present.

"accepted..."

"But it feels unreliable to me~www.wuxiaspot.com~Professor Gu frowned, and said in confusion: "Everyone else asked very clearly, but only Academician Xu seemed to be... In the dark, I don't know what I have to face at all. I think it's just a small problem. "

"???"

"???"

"???"

what's the situation?

Xu Mang didn't even know anything, so he directly agreed to help us solve the problem? Is it just a small problem?

All the people present glanced at each other, and saw the curiosity and fear in each other's eyes. What happened to Academician Xu? Could it be...is this the expression of confidence in the legend?

perhaps,

This is strength!
