For the first time in the world observed the ＂projection＂ of the gravitice in the world

Xinhua News Agency, Nanjing, March 28 (Reporter Chen Xiyuan) The reporter learned from Nanjing University that the international scientific research team led by Professor Du Lingjie of the School of Physics at the School of Physics has made significant progress in the field of quantum physics.projection”.Related papers published online on the 28th in the international academic journal “Nature”.
Du Lingjie introduced that gravitational seeds and gravitational waves corresponding to gravitational waves have been confirmed by the experiment, and gravitationals have not been directly observed.”Gravity is a product of the combination of broad theory of relativity and quantum mechanics. If this mysterious particles can exist, it may help to achieve the unity of the two major theories, which is of great significance to contemporary physics.”
He told reporters that in recent years, there are theoretical predictions that there may be a “divided number Hall effect gravitational child” in condensed material. Because its behavioral rules are similar to gravitational children, they are vividly called “projection” of gravites.Essence
Five years ago, Du Lingjie’s team found a new collective stimulation phenomenon in the sub -Hall effect.The theoretical physics community believes that this may be evidence of the existence of gravites in the segments Hall effect, and a experimental plan is proposed.
“But at that time, there was no measurement equipment that met the requirements of the experiment at home and abroad. Because this experiment had high requirements for the equipment and seemed to be contradictory.” Liang Jiehui, the first author of the paper and the doctoral student of Nanjing University, told reporters that on the one hand, the experimental needs need to be needed.Extremely low -temperature and strong magnetic field -temperature is only about 0.05 degrees Celsius higher than the absolute zero degree, and the magnetic field strength must reach more than 100,000 times the average magnetic field of the earth. Although these two conditions can be achieved through special refrigerators, on the other hand, in order to carry out the developmentOptical measurement must be installed on the refrigerator, which must easily cause the experimental temperature to rise, and the vibration of the machine will also affect the accuracy of optical measurement.
The team spent more than 3 years, and it was independently designed and assembled an experimental device on the campus of Nanjing University.”You can understand it as a two -storey ‘microscope’.” Du Lingjie said that after testing, multiple measurement parameters of the device reached the world’s leading level.
Relying on this weapon, the team successfully observed the quantity of the quantum Hall effect gravitational seeds in the quantum trap of arsenide, and confirmed the relevant experimental evidence from the perspective of spin, momentum, and energy.
“This is the first time that the concept of gravitational child has been proposed in the 1930s, the first observation of its’ projection ‘in the experiment.” Du Lingjie said that the team will continue to study the physical world of the gravitational submissions, “Looking forward to this’ microscope’ ‘Bring us more new discoveries in the frontier field of quantum. “
