As an unknown in the universe, dark matter is invisible and intangible, and hardly interacts with any object, but it accounts for 26.8% of the matter in the universe, which to a certain extent affects the structure and evolution of the entire universe.

As Qin Jingyu looked through more information and consulted papers, he gained a deeper understanding of dark matter.

In the past decade, more than 20 detection experiments to capture dark matter have been carried out internationally, using different detection methods, including "going up to the sky", "going down to the ground" and "artificial dark matter".

I understand why Parker and Steven thought that Professor Murphy was teasing her by giving her this topic.

There are more than 20 laboratories open to the public internationally that are studying dark matter. So many scientists have tried their best but still have not found a way to prove the existence of dark matter. Isn't it just a joke to teach Qin Jingyu a newcomer?

Qin Jingyu read some information in the apartment until late at night, and couldn't help laughing after he finished reading it.

After a few more days of looking up information, Qin Jingyu returned to the laboratory.

Steven smiled and said, "Hey, Qin, have you been missing these days? Parker and I thought you gave up."

Qin Jingyu put on his goggles. "Although it's difficult, I don't think it's time to give up. The notes you gave me are very useful. Thank you."

Parker: "You're welcome. I gave it to you in the hope that it would be helpful to you."

Steven: "We will be staying in the lab to work on projects recently. If you have any questions, you can come to us. Of course, if we don't know how to do it, then there's nothing we can do."

Qin Jingyu curled his lips and said, "I appreciate your kindness."

Since the 1980s, researchers have been hoping to use experiments to find the particles that make up dark matter.

If Qin Jingyu really wanted to use Professor Murphy's large underground laboratory to complete the project, one month would obviously not be enough. It also took her several days to look up information and papers, and the time was less than a month.

Professor Murphy also knew that there was not enough time, so he only allowed her to complete 50% to pass.

She had looked up information before and found that according to the official website of M Institute of Technology, under the leadership of Professor Zurek of Theoretical Physics, researchers began to seek new ideas.

Professor Sourek and his colleagues have been investigating the possibility that dark matter is made up of particles in a "hidden zone" that are lighter than previously assumed and could theoretically be discovered using tabletop experiments located underground.

They proposed this small tabletop experiment theory. At present, she has not found much data and conclusions about this experiment in the materials, but she looked up the papers published by Professor Su Ruik on tabletop experiments.

It was discovered that Professor Surik first proposed the concept of hidden zone particles many years ago. He introduced:

"Dark matter is always passing through us. As we move around the center of the galaxy, the steady wind of dark matter will usually go unnoticed, but we can still devise new ways to search for rare interactions between the dark matter wind and our detectors, depending on where the dark matter comes from."

In the paper, physicists including Professor Murphy outline how to detect lighter dark matter particles through a quasiparticle called a magnon.

Quasiparticles are an emergent phenomenon that appear when solids behave as if they contain weakly interacting particles.

A magnon is a quasi-particle that has the electron spin phenomenon. It acts like a small magnet and has a collective excitation effect.

In the tabletop experiment envisioned in Surek's paper, a magnetic crystal material would be used to search for signs of excited magnons produced by dark matter.

Qin Jingyu believes that compared to spending a lot of time observing and searching for dark matter in a large underground laboratory, this small desktop experimental setup seems to be more suitable for her at the moment.

So now the first step is that she needs to build a small desktop experiment.

There are many devices in Professor Murphy's laboratory, so it should not be difficult to build this small desktop experimental equipment.

However, if she wanted to start working in Professor Murphy's laboratory, she had to ask the professor for advice first.

After listening to Qin Jingyu's idea of ​​building a laboratory, Murphy suddenly showed some interest, but he still said, "So my laboratory is not enough for you, right?"

Qin Jingyu scratched the back of his nose. "Professor Murphy, let's be frank. You should know that with traditional experiments, in one month, I can only complete 50%, even 20% is difficult. When the deadline is up, you will get to see me go away as you wish."

Professor Murphy coughed lightly, feeling guilty.

She continued, "Of course, Professor Murphy definitely didn't mean to make things difficult for me and ask me to leave. This was actually a test for me. When the test results come out, you will be able to understand my level in physics experiments. You know that I participated in the development of the Hope, but in fact, you don't really agree with me in your heart, right?"

Seeing that Qin Jingyu had made it clear, Murphy also said, "You are indeed a smart child. No wonder John said that although you are young, you have a thorough understanding of everything. Indeed, the outside world has spread you as a genius, and the international community calls you a genius.

I admit and agree with John that you have a talent in mathematics that surpasses those old guys, but mathematics is different from physics. You calculated the parameters of the quantum engine, but that just happened to be the numerical model that you are best at, and you did not participate in the development of the Hope throughout the entire process.

My understanding of you is limited to various reports and John's description of you, but those reports often contain some exaggeration or derogatory elements.

If you want to be my student, I need to know what kind of person you are. I don't accept mediocre people. You should have met Parker and Steven. Although I have called them pigs, they are also people who stand out among the many students at Purdue University. "

"So Qin, this is a test question and also a test question."

Professor Murphy was not like other professors in the academy, who were eager to accept Qin Jingyu as a student because of his great achievements in the mathematical academic world. He had his own standard line in his heart, and this standard line was customized by himself.

Qin Jingyu has read the notes made by Parker and Steven themselves, and it can be seen from them that they are very powerful people.

Regarding the development of the Hope, she only participated in the calculation of the parameters of the quantum engine, which happened to be the part she was good at. So in Professor Murphy's mind, she did not participate in the development of the Hope throughout the whole process, and he did not think that she could have the same talent in mathematics as in physics.

The difficult assignment he gave her was not meant to tease her, nor was it meant to make her feel ashamed when she was persuaded to drop out. Instead, it was a threshold he set for his students.

Qin Jingyu is still outside his threshold.

"Professor, since this is a test question, shouldn't we let the candidates express themselves as they please?"

"Of course, as long as the final answer is correct."

"Then professor, do you agree that I can do whatever I want on your territory?"

Professor Murphy spread his hands, "Did I say no?"

"Thank you, Professor."

"You want to get a small desktop experimental device from me because of the paper published by Professor Su Ruike?"

"I can't hide it from the professor."

Professor Murphy snorted. There was everything he didn't know, but he didn't expect that this kid was so smart and knew about the small desktop experiment so quickly.

He suppressed the corners of his mouth that were about to rise uncontrollably, and said in a serious tone: "Okay, don't waste your time here. Do whatever you want. I will give you the greatest authority in the laboratory."

He was already looking forward to what Qin Jingyu would come up with in the end.
