Chapter 492: Looking for fragile topologies

Chapter 492 Searching for Fragile Topology (13, seeking votes)
a new day,
Xu Mang went to his laboratory with a pile of books.
The road from his Fuda apartment to the laboratory was long, and Xu Mang was successfully blocked on the elevated during the rush hour. Traffic jams are what happens every day in this city. Xu Mang has long been used to it.
About half an hour later,
Xu Mang finally got off the elevated highway and went all the way to the laboratory.
"Ugh?"
"Is it the earliest?"
Xu Mang found out that he was the first one today. When he came here, everyone had already started working. He glanced at the time... it was only half past seven. At this time, Xu Mang was in a daze.
I...
Wrong time.
Helpless Xu Mang could only come to the office silently, took out a physics book, covered his face directly and started sleeping.
Physical skills +5
Physical skills +5
Currently,
The work of gravitational wave detection is stuck, and the solution is to find a mathematical tool for accurately calculating gravitational waves. Unfortunately, Xu Mang does not know this mathematical tool, and the exchange value of the system is very large...
It requires three skills of mathematics, physics and astronomy to be proficient, and consumes millions of skill points.
fortunately,
Since the intelligence reached level 4, the value obtained has been directly increased by five times, which means that in the future, I can master the skills faster and upgrade its related levels. So it seems that this system is quite good. I used it as the Taibai cat. Big pit cargo...
Mistakes,
Pure mistake!
for a long time,
A young woman came to the office, Wang Ai, the daughter of Professor Wang Jiafuwang. She came to the office as usual and woke Xu Mang who was sleeping.
"Xu...Xu Mang!"
In private,
Wang Ai’s name is Xu Mang, usually his full name. Although every cell in his body admires Xu Mang, his soul is repelling him. However, Wang Ai is very polite. When there are many people, she will be respectful. Shout to Professor Xu.
"Uh?"
"Why...what's the matter?" Xu Mang took off the data covering his face, looked at her with a confused look, and asked curiously: "Don't go to work...what do you want me to do?"
"..."
"There is nothing else to do now." Wang Ai said with a black face: "The mathematical tool for calculating gravitational waves, have you solved it?"
"No."
"Any problem?" Xu Mang asked.
I...
This...
Since the problem has not been solved, how did he sleep so soundly?
Hearing Xu Mang's words, Wang Ai almost didn't collapse. Did he meet someone? Don't you know what's going on now? Don't you know how much progress you are behind others? Don't know how many difficulties the laboratory is facing?
"you..."
"Forget it!" Wang Ai said angrily: "It doesn't matter to me anyway, just do whatever you like."
"Hey..."
"Don't panic!" Xu Mang said with a grin: "Gravitational waves appeared in Einstein's general theory of relativity in 1915. It has been a total of one hundred and four years since we are talking. Many people have been searching for gravitational waves for 104 years, but they have not found anything."
"Do you know what it means?" Xu Mang asked with a smile.
Wang Ai frowned and replied earnestly: "It means it is extremely difficult."
"wrong!"
"This means that one hundred and four years have passed, and it doesn't matter if one more year is passed." Xu Mang said, "Understand?"
Wang Ai: @#￥%...!
What is this theory?
Salted fish theory?
"If you continue to do this, I'm going to call and file a complaint with Xiaoman!" Wang Ai had no choice but to seek help from Yang Xiaoman.
Not to mention,
This trick worked especially well, and Xu Mang woke up instantly.
"do not!"
"If you have something to say, can you not involve that tigress?" Xu Mang said helplessly: "As for the mathematical tools for calculating gravitational waves...I really have no clue at the moment. Think about it...the world The famous scientist Xu Mang doesn't even know this question, aren't others talking nonsense?"
"You said it earlier!"
"At present, "Science" has passed our quantum probability paper, and you are the corresponding author." Wang Ai said, "There is nothing to do now."
"Nothing to do... Find something to do."
"Can living people be suffocated by urine?" Xu Mang said indifferently: "Now our research funds are very sufficient. Do whatever you like. Don't have any scruples... Tell you a rough figure. We have at least two. One billion!"
Two billion?
cut!
It is not used in the laboratory.
Wang Ai knew that a research institute was being built next door, and estimated that 2 billion was the funding of the research institute next door.
"Ugh?"
"Speaking of the current scientific world, are there any new discoveries?" Xu Mang sat in a chair and asked curiously: "Since we still can't solve the mathematical tools for calculating gravitational waves, we might as well set our sights on other fields again for the time being. Can you make a breakthrough."
"just now..."
"The most popular research in the world is graphene and topological state." Wang Ai said: "Graphene is based on your findings. Many research institutions around the world are looking for new superconductors, and the topological state is also because of your graphene superconductivity. , From a strange thing to one of the hottest researches in physics."
what?
Topological state?
Xu Mang was stunned for a moment. Topological states had previously learned that due to the strange properties of electronic kinks and quantum states, this is a very unpopular concept. Why did it suddenly become popular? Is it also related to graphene superconductivity?
"Be specific," Xu Mang said.
"Just..."
"The Oxford University research team discovered a topological structure that appears in almost all solid crystals. This structure is called fragile topology." Wang Ai said: "According to the Oxford University research team, almost all materials have a certain topology. state."
"At present, this fragile topology has only indirect evidence, no direct evidence..." Wang Ai continued: "Now the whole world is looking for this evidence."
Xu Mang nodded, and said with a bewildered face: "What does that have to do with graphene?"
"The Oxford University research team discovered this topology from your double-layer magic-angle graphene. Some electronic states contained in the twisted graphene show a suspected fragile topology." Wang Ai seriously. Said: "This is calculated by pure mathematics."
I...
Nima!
Why didn't I find out?
Hearing Wang Ai's words, Xu Mang almost died of anger, and every cell in his body was very upset.
Why is the double-layer graphene discovered by the dude, but this topology is found by Oxford University? Shouldn't they all belong to buddies?
"Are you furious?"
"It's useless to be angry...Who didn't let you find out." Wang Ai said with a grin.
"What am I..."
[Trigger task: Fragile topology state]
[Explanation: Find this kind of evidence that can give the material a strange property]
[Reward: Upgrade Card20]
When Xu Mang was halfway through the conversation, he saw that the system had issued a brand new task, and he even asked himself to find evidence of fragile topology.
"Go back and talk to other people and have a small meeting." Xu Mang said.
Wang Ai:? ? ?
soon,
meeting room.
Xu Mang announced the next research direction. As there is no mathematical tool for calculating gravitational waves, the temporary research direction is now to find evidence of fragile topology. However, this decision has met with opposition from many people.
"Professor Xu!"
"The fragile topology is a very radical academic bottomless pit. Anyone who enters is stuck in the quagmire and can't get out." Dong Yu said seriously: "I think we change one. Brother Chuan Xiao proposed to explore the first chemistry of the universe yesterday. The product of the reaction, helium hydride ion."
"what?"
"You already have..."
suddenly,
Xu Mang was interrupted by the system again.
[Trigger task: Origin]
[Description: Explore the starting point of the birth of stars, planets and life-helium hydrogen ion]
[Reward: Upgrade Card10]
I...
Damn it!
What's the situation?
It used to wait for a thousand years before, but now one comes at every turn.
so awkward,
How should I choose?
In fact, Xu Mang really wants to choose the mission of'origin'. After all, he is facing the sea of ​​stars. Helium hydride ions are a kind of mysterious ion, because helium hydride ions cannot be observed. For humans, they are in the universe. invisible.
And not only helium hydride ions, many first-generation molecules in the universe are in a state of invisibility. These invisible molecules constitute a very important period in the universe. This period is called the dark age and is also called the origin.
"Well then."
"We formed two groups, the fragile topology group and the helium hydride ion group." Xu Mang smiled and said, "Is anyone willing to study fragile topology with me?"
Words fall,
The scene was silent.
"What about the helium hydride ion group?" Xu Mang asked, "This interesting research project."
"I am I!"
"Add me!"
"me too!"
Everyone joined Brother Chuan Xiao's group.
Xu Mang: 囧
This group of people...
It's too bad, right?
But let alone... I want to study helium hydrogen ions.
"Xu Mang!"
"Let's study the helium hydride ions together." Brother Chuan Xiao said: "We can only be competitive if you are with us. The difficulty of the fragile topology is too high, and it may not be rewarding."
"in fact..."
"I also want to study the product of the first chemical reaction in the universe, and want to see its true colors." Xu Mang sighed: "But...anyway, the situation is very complicated. I can only choose fragile topology and find and calculate gravitational waves by the way. Mathematical tools."
The truth is the task of fragile topology, and the reward is richer than the helium hydrogen ion task.
finally,
Xu Mang alone studied the boring fragile topology, while Brother Chuan Xiao took the whole team to study the product of the first chemical reaction in the very interesting universe.
suddenly,
Xu Mang felt that he was particularly lonely.
...
noon,
back to school,
Xu Mang went to the cafeteria for a little meal first, then stayed alone in the apartment, and began to look for information about fragile topology. Because it was a new field of physics research, there was very little information about fragile topology.
Without any choice,
Xu Mang can only start from the beginning and study from the most basic branch of mathematics. In fact, topology is only a branch of mathematics. It studies the continuous deformation of objects and cannot cut or split objects.
Almost an hour has passed without much gain.
"The direction is wrong..."
"Ugh..."
Xu Mang sighed ~EbookFREE.me~ This thing is really not ordinary boring.
quickly,
Xiaoman returned to the apartment, glanced at her with a smile at this time, and knew that this fierce peasant woman had a good harvest today.
"Dear!"
"I earned you a Ferrari today!" Yang Xiaoman hugged Xu Mang from behind and said with a smile: "Is your wife good?"
"what?"
Yang Xiaoman looked at the computer screen and asked in surprise: "Why are you also studying fragile topology?"
......
Uh... ask for a monthly pass...
