China News Agency, Hefei, January 5th (Reporter Wu Lan) Wave-particle duality is the cornerstone principle of quantum mechanics, and it is also one of the sources of quantum mechanics' "counter-common sense" and "counter-intuition".
The single-particle double-slit interference thought experiment can explain the wave-particle duality very directly from the phenomenon.
For nearly half a century, experimentalists have successively used photons, electrons, atoms, molecules and biological macromolecules as interference entities to realize the double-slit interference thought experiment of single particles.
Then, can the common unstable particles in high-energy nuclear physics experiments also produce the phenomenon of double-slit interference as entities?
The reporter learned from the University of Science and Technology of China on the 5th that the joint research team of the university's high-energy nuclear physics research group, Brookhaven National Laboratory, Shandong University and other units played a leading role in the STAR international cooperation group and realized the Fermi nuclear energy for the first time. Scale single-particle double-slit interference experiments.
The research results were published in "Science Advances" (Science Advances) on January 4.
STAR is a large-scale international cooperation group based on the STAR experiment on the Relativistic Heavy Ion Collider of the Brookhaven National Laboratory in the United States, consisting of more than 700 researchers from 71 units in 14 countries.
The High Energy Nuclear Physics Research Group of the University of Science and Technology of China is an important research force of the STAR International Cooperation Group.
According to reports, the research team of STAR used the unstable particle ρ0 (with a lifetime of about 1 Fermi/speed of light) produced by coherent light in very high-energy nuclear collisions as an interference entity to realize a Fermi-scale double-slit interference experiment. Currently the smallest double-slit interference experiment.
During the interfering process of correlated collision strokes, the phenomenon of double-slit interference is manifested in the polarized space for the first time.
Interestingly, in these collisions, the double-slit interference is actually produced by the cooperation of its decay products (such as π+π-pairs), among these decay products, the π+π-pairs cooperate to complete the interference “over time and space” , is an excellent model to explain the phenomenon of quantum entanglement.
