Reporter today (13th) learned from the University of Science and Technology of China that the schools Professor Peng Xinhua, Associate Professor Jiang Min, and others use quantum precision measurement technology to make important progress in the detection of shaft dark matter.The international exploration boundary has been raised by at least 50 times.The results have recently been published in the international academic journal "Physics Review Express".Many theoretical predictions that surpass standard models that the axis is a candidate particle that constitutes dark substances.In this research work, the scientific research team used two polarized atomic comprehensives of 60 mm apart to detect the spin -related interaction induced by dark matter in the "axis window".
Researchers have also designed the magnetic shielding system to successfully weaken the classic magnetic field signal of the environment to one billionth, and use it in the gravityThe optimal filtering technology is widely used in wave detection, maximizing the signal -to -noise ratio of the axis signal.Through experiments, the scientific research team gave the strongest neutron -neutron coupling boundary in the "axis window", and increased the previous international detection boundaries by more than 50 times, setting a new international best record.This achievement not only shows the huge potential of quantum precision measurement technology in the field of dark matter detection, but also lays a solid foundation for future related research.
