Facing this hypothetical particle from forty-two years ago again, Xu Mang had a rough guess after completing the Weyl semimetal and Weyl fermions. He suspected that axion properties could be captured in solid crystals.

A type of particle.

certainly,

The conjecture here needs to be supported by a theoretical framework. What Xu Mang is currently working on is to improve the theoretical framework and how to use existing physical concepts to describe axions or axion-like particles.

In Xu Mang's theoretical framework, he still chose the tase family crystal that he had discovered before, but this time he chose the tase4 crystal.

but...

At this time, Xu Mang encountered some troubles. He found that even after finding Weyl's semimetals and fermions, he still had many difficulties with the axion problem. There was an invisible force that was hindering his progress.

What exactly is it?

Xu Mang doesn't know yet, he is also looking for this problem.

"well..."

"It's so difficult for me..." Xu Mang simply lay on the chair with his legs crossed. Although his clothes were in a state of shame, the word 'sorrow' was written all over his forehead.

At this time,

The phone rang. I glanced at the caller and realized that I had to answer the call. It was from my father-in-law.

"Hello?"

"Dad...what do you want from me?" Xu Mang asked with a smile.

"Xiao Xu."

"When do you have time?" Yang Jian's tone was a little relaxed, and there was no rush in his words. "The main reason is that your aunt misses you and Xiaoman. She hasn't come home to see her for so long. She has been always

Complaining."

Ouch!

I actually forgot about this.

It was almost a tragedy.

"Ahem!"

"Dad... I've been a little busy recently, you should know that." Xu Mang awkwardly and politely put all the responsibilities on Xiao Man, and said with a smile: "The work pressure is very high, I really can't take it away.

I came here to see you and mom, but... didn't I ask Xiaoman to come? Could it be that... she didn't come? "

"You asked Xiaoman to come see us?"

"Why didn't I see her?"

Hearing Xu Mang's words, Yang Jian frowned and tried to recall the past fragments. After thinking for a long time, he was sure that he had never seen his daughter. He couldn't help but said, "When did you ask Xiaoman to come?"

"ah?"

"I urge her to go back to her parents' home every day..." Xu Mang shook the pot with a serious face: "I can't help it. You should know how heavy the burden is on me. If there is no such heavy burden, I will do it myself.

Came to see you and mom."

"I see..."

"You still make us very excited." Yang Jian sighed and said helplessly: "My daughter has grown up...she is becoming less and less filial."

Xu Mang hurriedly continued: "No, no, no... Dad, don't think like this. In fact, Xiaoman is also very hard-working. She has to manage a company and use finance to cut leeks outside. It's very hard!"

"

Well?

Financial cutting of leeks?

Is Xiaoman playing in finance?

Yang Jian's expression gradually became tense and he asked hurriedly: "Xiao Xu... tell the truth, what is Xiao Man doing recently?"

Damn it!

I accidentally let it slip!

It's over, it's over, now I've tricked my wife.

certainly,

What Xu Mang was afraid of was not whether Xiaoman would be scolded by Yang Jian, but also thinking that after Xiaoman was scolded, she would definitely retaliate against herself by multiplying her grievances a hundred times and using violence.

When the time comes... not only will I receive a sweet beating, but I will also spend an entire night with her.

I lost my wife and lost my troops,

What a bargain!

"Well..."

"What about that? Why don't you ask it yourself?" Xu Mang said cautiously: "I... Dad, don't you understand what your daughter's temper is like? If she finds out that I am the one who told the secret, I'm afraid she will

Fight with me."

"Um!"

"I'm hanging up now. I'll come home often when I have time."

"oh..."

snap,

call interrupted,

Xu Mang hurriedly opened WeChat and sent a message to Yang Xiaoman.

The dream of all female creatures in the universe: Be careful, there is a mole!

moment,

Yang Xiaoman responded to the message.

Bits and pieces of life: big idiot!

Bits and pieces of life: Can you be a little more normal? Don’t be a guilty person. Remember that you are a great scientist!

after,

Xiaoman never sent another message. Xu Mang knew why. He guessed that his father-in-law was talking to Xiaoman about life. By the way...turn off your phone. You will definitely receive an angry message from Yang Xiaoman later.

Incoming call.

As expected,

Murphy's Law happened. The theme song of "Lawyer's Letter" rang on the phone, and the caller was classmate Yang Xiaoman.

"Hello!"

"Did you tell the secret?" Yang Xiaoman asked angrily: "Dad scolded me all over my face... You must be a big idiot who let it slip. You... Xu Mang, you will die tonight.

Well, if you don’t serve me well today, you won’t live to see the sun the next day.”

snap,

The call was hung up.

Xu Mang shrank his head, it was really unlucky for him to drink so much that his teeth were blocked.

When I think of night,

Ouch...kidney pain!

After feeling melancholy for a while, Xu Mang returned to the problem. What he was currently encountering was the incompleteness of the theoretical framework. It was impossible to complete this framework with current physics, and there were still many loopholes to be filled.

cool,

After struggling for so long, the result is that it still cannot be completed.

Xu Mang sighed with a look of despair. This hypothetical particle is really not that difficult. To explore an unknown particle theoretically, it is better to use a particle collider to blast out a future world. If...

It would be nice if I had my own particle collider.

No matter what,

It’s too expensive!

Investments of tens of billions are still in US dollars.

"never mind..."

"Go for a walk outside and look for inspiration." Xu Mang stretched out. He originally thought that he had broken through the Weyl fermion and would be very relaxed when facing this axion particle. The result was not what he thought. Although

To some extent, the direction has been given, but this direction is still full of potholes.

Along the way, I met many researchers from this institute. When facing Xu Mang, they were full of respect and would kindly say "Professor Xu". Of course, in response, Xu Mang would basically smile back to others.

Then,

Smiling and laughing...my mouth cramped.

"Professor Xu?"
