Time crystals represent a new phase of matter proposed by Frank Wilczek, the Nobel laureate of Physics in 2004; they can break original time-translation symmetry and create new time oscillations spontaneously.<\/p>\n

Recently, a joint research team from the National Time Service Center (NTSC) of the Chinese Academy of Sciences and Shanghai Jiao Tong University observed a time crystal in a spin<\/a> maser system.<\/p>\n

The results are published<\/a> in Communications Physics.<\/p>\n

In this study, the researchers investigated a Rb-Xe hybrid atomic spin maser system. They discovered that when the interaction strength of the spin-feedback magnetic field surpasses that of the spin\u2013DC magnetic field<\/a>, a distinct spin oscillation signal emerges. The signal oscillates with a frequency<\/a> totally different from that of the original spin Larmor precession, and it has random phases and shows high robustness over repeated experiments, fitting the definition of time crystals<\/a>.<\/p>\n

“Our research provides an alternative scheme to the existing time crystals,” said Prof. Liu Guobin, leader of the atomic spin gyroscope research group from NTSC.<\/p>\n

The time crystal in a spin maser could potentially be used for both fundamental studies and practical applications based on precision measurement physics.<\/p>\n
