Shen Qi and Ou Ye have moved to the house, the 150-square-meter house has complete furniture and electrical appliances, and the 90-square-meter upstairs has been simply arranged.

Shen Qi and Ou Ye were lying on the bed chatting, and Shen Qi reported the family's financial information: "We brought back a total of $5.03 million from the United States, plus the $25,000 bonus you just received, our current assets are equivalent to about 35.38 million soft sister coins, which is living money, not including houses and cars." ”

"You're pretty good at making money. Ou Ye listened to Shen Qi's report and made comments.

The $5.03 million brought back by the United States was earned by Shen Qi alone, including bonuses, salaries, and sales revenue from academic monographs.

After Ou Ye returned to China, she also joined the money team, and she contributed 25,000 US dollars.

"Your math grades are relatively good, and you will be in charge of the money in the future. Shen Qi stuffed the bank card into Ou Ye's hand and instructed: "The money for our marriage is in it, and the hard-earned money is not easy to come by, so we still have to save some money." ”

"Your consciousness is so high. Ou Ye is satisfied with Shen Qi's performance, man, the most important thing is attitude.

Ou Ye took Shen Qi's bank card and touched it, and returned it to Shen Qi: "You have more social experience than me, or you take care of the money." ”

"Well, I'll keep it for you. "Shen Qi is better than obeying his orders if he is respectful.

"Don't mess around. Ou Ye reminded.

"Who dares to spend the money for marrying a daughter-in-law?" Shen Qi's wife has almost saved enough, the house is there, the country has it, the car is there, and Ou Ye's father gave it, more than 30 million Chinese and Western weddings of any kind will not be too shabby.

With a smooth career and a happy love, Shen Qi is a big winner in life in the eyes of others.

Shen Qi is not complacent, he realizes that he still has shortcomings in many aspects and needs continuous improvement.

The 973 project of "Application and Expansion of Defect Topology Research in Condensed Matter Materials" was finally approved, and Shen Qi was approved with a fund of 5 million yuan to meet Shen Qi's needs.

Shen Qi purchased basic condensed matter physics experimental equipment such as X-ray instrument, spectrometer, laser device, etc., and he did it alone in the selection and inspection of goods and debugging equipment, and Shen Qi was the strongest in the whole center.

Shen Qi has set up a laboratory on the third floor of the mathematics building, and he has been in the laboratory every day recently, doing experiments and collecting real data.

For the research on the origin mechanism of the complex oxide q2DEG, Shen Qi is still continuing.

Condensed matter matter is all-encompassing, and complex oxides are not just complex oxides.

Shen Qi simultaneously carried out the research work on nanoscale amorphous alloys, and selected a typical zirconium-based amorphous alloy as the experimental material, with a nominal composition of Zr41.2Ti13.8Cu12.5Ni10Be22.5 (atomic percentage).

In order to obtain an effective X-ray scattering signal at a small angle, the sample is prepared into a thin band with a thickness of about 20 μm.

The preparation of samples of this specification requires the use of a high-vacuum single-roller spin quenching machine, which is quite expensive, and Shen Qi cannot afford it for the time being, so he entrusts the Yan University Institute to help prepare the samples, and the Yan University Institute has such a machine.

It really costs money to do physics research, and 5 million soft girl coins are not used, which is converted into less than 1 million dollars.

Shen Qi knows very well that $1 million is basically nothing to do in the physics department of Princeton, and the PPPL plasma laboratory in Princeton burns nearly $1 billion a year, while Yan University's annual scientific research funding is only 3 billion soft sister coins.

The first physics project after returning to China, Shen Qi was embarrassed to ask the country for too much money, 5 million is 5 million, spending a small amount of money can still do big things, the key is to see who the person who uses the money is.

Shen Qi repeats the same thing every day, adjusting the receiving angle range of the 12A beam to -3.5-0mrad horizontally, (0.36±0.18) mrad vertically, the incident X-ray wavelength of 0.154nm, the angular resolution of 0.5mrad, the energy resolution (△E/E) of about 10 to the negative power, and the luminous flux of 1×10^11cps with a distance of 1 meter from the sample to the detector......

The inspection of experimental equipment and the preparation of the experiment were completed, and the morning passed.

In the afternoon, the machine starts up and performs small-angle X-ray diffraction on the zirconium-based amorphous alloy sample.

As soon as the machine was turned on, Shen Qi had to stay in the laboratory to prevent fire or sabotage by saboteurs.

Buzzing, the experimental machine makes a regular vibration sound.

At room temperature, the sample is stretched to fracture and broken, and the detector begins to collect real-time data to measure the scattering intensity patches with an exposure time of 5 minutes for each patch.

Shen Qi used FIT2D software to process the data of the original spot map in the laboratory, first normalized the scattering data of the sample and the back, and then deducted the backscattering data to obtain the scattering data of the amorphous sample.

Finally, there is some mathematical finishing to do a small angle of fan integration along the stretching direction, today's angle, Shen Qi set it at 10 degrees.

From morning to night, Shen Qi worked all day to get an A4 piece of paper, on which the one-dimensional scattering curve of the sample was printed.

This A4 paper embodies the patience, carefulness and sense of responsibility of scientific researchers, as well as an ambition to seek breakthroughs.

At the end of the 19th century, a British physicist named Rayleigh discovered an incredible thing when studying nitrogen: the nitrogen produced from the air was always slightly heavier than the nitrogen prepared from nitrogen-containing compounds such as ammonia - 0.0064 grams.

Rayleigh spent two years doing repeated experiments, doing the same experiment, perseverance, repeated observation and verification, and finally came to an astonishing conclusion that there is a "lazy" gas in the air - argon. Argon means laziness in Greek.

Times are changing, experimental equipment is upgrading, but the tradition of experimental physicists has continued, doing experiments, constantly doing experiments, so that the world is old and retired.

"It's fun to go to the lab, but I can't go to the lab all day. Shen Qi gets an A4 piece of paper a day, and he estimates that he has to collect at least 100 sheets before he can establish a theoretical system.

This is not only in the field of amorphous alloys, but also complex oxides, superconductors, various nanomaterials, as well as polymers and biopolymers.

The Nobel Prize in Physics is not so easy to come by, and Shen Qi knows that it is difficult for most physicists to recognize theories that are not supported by experimental data.

It is necessary for graduate students and doctoral students to soak in the laboratory.

Shen Qi is such a big leader, it is impossible to do experiments and calculate simulation data every day, his responsibility is to grasp the strategic direction, put forward innovative ideas, most of the specific and tedious experimental work should be handed over to his subordinates to do, Shen Qi occasionally supervises it is OK.

This returned to the topic of talents, Shen Qi summoned Cui Xiaoyi into his director's office and asked, "Why hasn't the doctor of physics been in place yet, and what are the difficulties?"
