"Answer the concept of length contraction of time dilation in the theory of relativity." Xu Mang asked.

"Eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee..."

Although he didn't know what to say, Xu Mang still nodded, showed a smile, and said, "Very good, your mother is much smarter!"

"Hey, hey, hey!"

"Xu Yang!"

"Look at sister...look at you again. Come home and see if I don't spank you!" Xu Mang looked at his son. At this moment, he felt that his son was extremely naughty compared to his daughter.

after,

Xu Mang put away his playfulness and began to design a new ion trap design for the quantum clock to reduce thermally induced ion motion and make the operation closer to the ideal ground state, or the lowest motion energy level. Then he had to choose an appropriate frequency.

.

Because a lower frequency is used to operate the ion trap, unnecessary ion motion caused by the electric field used in the ion trap can be reduced.

This is just the beginning,

There is also improved quantum control that reduces measurement uncertainty of frequency shifts caused by ion motion.

noon,

Xu Mang, who had been busy all morning, stretched out and found that the children were already asleep. He couldn't help but take out two bananas. He was in a hurry to go out... He forgot to bring lunch, but only brought some fruits.

no way...

Let's eat together.

Sudden,

The office door was opened, and Yang Xiaoman walked in with a stern expression on her face, carrying takeaway food.

"Are you starving to death?" Yang Xiaoman rolled her eyes at Xu Mang and said angrily: "You don't even bring food with you when you go out in the morning. You just left in a hurry...what an idiot!"

"hey-hey!"

"Honey, you're so kind." Xu Mang said with a smile, "Ouch? It's braised pork?"

"..."

"Is the baby fussy?" Yang Xiaoman said seriously while taking out vegetables and rice from the bag: "In a strange environment."

"No."

"I also told the children about the concept of time dilation in the theory of relativity and the concept of ion traps." Xu Mang smiled and said, "Listen carefully!"

Yang Xiaoman:(#￣～￣#)

at this moment,

A song appeared in Xiaoman's mind... Children, do you have many question marks?

after lunch,

Xiaoman originally planned to entertain the children for a while, but seeing that they were sleeping so soundly and not having the heart to disturb their dreams, he could only leave the institute quietly.

Subsequently,

Xu Mang started working, but the work was at a stalemate. Regarding the new ion trap design, progress was a little slow.

"What should we do?" Xu Mang sighed and stared at the computer boredly, feeling a little dazed for a while.

"Eaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"

Daughter Xu Man woke up and kept talking to Xu Mang.

"Yo yo yo..."

"Is daddy's little cotton-padded jacket awake?" Xu Mang happily held the child in his arms, kept teasing her, and said, "Do you miss daddy?"

Faced with Xu Mang's inquiry,

Xu Man kept talking, as if he wanted to express something, maybe his love for his father.

snap,

A crisp sound,

Xu Man's noisy little feet kicked the keyboard, making her cry instantly.

"Don't cry, don't cry!" Xu Mang was also anxious, slapped the keyboard hard, and said, "Dad has already called you back, we don't cry, don't cry..."

At this time,

When Xu Man stopped crying, Xu Mang saw an astonishing scene. A webpage popped up in front of the screen, and the content of this webpage turned out to be... a certain paper on ion traps.

Just reading the abstract, Xu Mang suddenly understood.

yes!

Isn’t this enough?

"Xu Man!"

"You are really dad's caring little cotton-padded jacket!" Xu Mang rubbed his daughter's little face affectionately with his own, and said excitedly: "Your kick... directly solved a confusion in dad's heart!"

Xu Man:???
