I really don't want to lie down and win

Xu Mang froze for a moment, then asked curiously, "Have you been deducted money again?"

Although he didn't know why Xu Mang said again, at this moment, Xiao Zheng could only follow him and say, "Yes...the funds were cut off again."

Xu Mang was very upset. This research is poisonous, right?

This...

Doesn't this mean that you have harmed others?

"Email me the question."

"it is good!"

moment,

Xiao Zheng sent Xu Mang an email, which contained the problems his team encountered and the current experimental data.

According to Xiao Zheng's thinking, it would take at least a week to solve this problem. As a result... 5 minutes later, she received a call from Xu Mang.

"Xiao Zheng, right?"

"I have already understood my situation, and this problem will be resolved tomorrow morning."

Hearing Xu Mang's words,

Xiao Zheng was at a loss.

......

Chapter 435 Not enough qualifications! (1/3, please subscribe)

Xiao Zheng's question is actually not very difficult, at least it is not difficult for Xu Mang. When Xu Mang saw this question, the first theory that came to mind was to control the lattice constant and electron density of graphene. It is possible to realize the continuous change of graphene from metallic to insulating state.

That's about as superconducting as its own three-layer graphene, but with a slightly different core.

If the interaction between electrons is strong, each electron is associated with other electrons, and the movement of an electron will be strongly constrained by other electrons, so the Coulomb interaction between the conductive electrons in the material is greater than the kinetic energy of the electrons, which will make The movement of electrons becomes difficult.

Thus an insulating state is formed.

actually...

It is the strongly correlated electron system in the theory of condensed matter physics, a system in which the interaction between electrons cannot be ignored.

"Ugh..."

"This needs to be overthrown and started again." Xu Mang sighed helplessly, and silently recalculated from the theory, at least according to Xiao Zheng's request, to complete the establishment of this theoretical framework, otherwise the road ahead would be very difficult for them.

"Fool?"

"Whose call was it just now?" Yang Xiaoman flipped through the menu and asked curiously: "I seem to hear a woman's voice, the voice is quite gentle... Do you need to explain to me ?”

"I'm a student."

"I arranged to work in the Institute of Materials Technology, Academy of Sciences." Xu Mang said blankly, "This research is poisonous...Because of the research progress, the scientific research funds were cut off again, so I came to look for it when I had nowhere to go." I."

Yang Xiaoman nodded, and said seriously: "Since it's your student, then I have to help, and it's you who pushed him into the fire pit, it's a little too much not to help."

"I see..."

"Isn't this helping to establish a theoretical framework?" Xu Mang said, "I won't go to bed at night, so go to bed by yourself."

"what?"

"I..." Yang Xiaoman felt very uncomfortable, she felt that she had dug a big hole for herself, and said helplessly: "Helping is helping, but you still have to sleep, your body is important."

at this time,

Xu Mang didn't talk to Xiaoman, but just made a graphene model in front of the computer, which was actually copied from his own three-layer graphene theory, because the bottom of the three-layer graphene energy band is very flat, which means that electrons have Great effective mass.

Simultaneously,

Xu Mang still chose boron nitride as a material composed of nitrogen atoms and boron atoms, but in the process of design control, Xu Mang adopted a different concept from superconductivity, using two voltages to control the graphene system in situ. The strength of the interaction of electrons in the electron makes the effective mass of the electron larger.

As a result,

It realizes the transformation of graphene from a metal state conductor to an insulating state conductor, just need to follow the switch, and it is still at normal temperature, not a temperature of a few Kelvin.

of course,

Xu Mang would not give Xiao Zheng and the others such a detailed process. He could only give a core theory, which is a rough framework. Under this theoretical framework, let Xiao Zheng and the others complete it by themselves. If everything is done, Also study a ghost.

calculate...

Finally, it's time to calculate again.

After designing the theory, the next step is endless calculation, and this calculation process is the Hamiltonian operator that Xu Mang hates the most. It is composed of pure point, absolute continuity and singularity. It is one of the hated and desperate concepts of quantum mechanics. One, but it cannot be used, after all, the Hamiltonian operator can calculate the time evolution of the quantum state.

How to do?

Need to find a tool person.

At this time,

Xu Mang saw Yang Xiaoman who was studying the recipes. Although Xiaoman didn't know much about physics, she was very good at mathematics. She only needed to be taught to understand it. How about... fooling around?

"Wife!" Xu Mang shouted.

moment,

Yang Xiaoman's soul has been sublimated. This is the first time that Xiaoman was called his wife by Xu Mang. Normally, he was only called dear, and dear is already the limit of the limit. Who would have thought that he would suddenly be called "my wife" today? wife...

"Husband" Yang Xiaoman flew into Xu Mang's arms, his hands were like cat's claws, his joints were slightly bent, and he said happily, "I love you, I love you!"

Hear this,

Xu Mang's scalp was numb.

But he understands a truth, even a domineering girl like Yang Xiaoman still has a cute side hidden deep inside, but this hidden attribute is too difficult to trigger.

Suppressing the discomfort, Xu Mang said with a smile, "I...I have something to do, can you help me figure it out?"

"Okay, husband." Yang Xiaoman nodded, and said with a smile: "My wife, I will help you do it with your heart."

"Ha ha..."

"Ok!"

Xu Mang smiled and nodded.
