Physics and measurements are inseparable. Precision measurements play a significant role in testing existing physics laws, in determining fundamental physical constants, and in searching for new physics beyond the standard model of particle physics. With unprecedented advances in the development of atomic clocks, time-frequency measurement has become an important tool for such basic research and even for deep space exploration. At the same time, time-frequency technology has brought huge benefits to national well-being and social life, ranging from navigation and positioning, high-speed communication, smart grid, and national finance and securities.
A great deal of effort has been made recently to promote time-frequency technology, including the generation, measurement, keeping, and transfer of high-precision time-frequency signals. For example, rapidly advancing atomic clock technologies have made it possible to build time standards with an accuracy better than 10-18. With the maturity of long-distance optical fiber transmission engineering, the high-fidelity time-frequency transmission of thousand-kilometer optical fiber has reached a timing accuracy of several picoseconds and frequency stability of 10-19. Combined with quantum technology, time transfer even shows the potential to reach the level of femtosecond precision. This Research Topic focuses on the latest progress in high-precision time-frequency research and related applications, and further explores the importance and potential of high-precision time-frequency technology.
The 9th International Symposium on Cold Atom Physics will be held in Quanzhou, China between June 29th and July 2nd, 2022. The conference chairmen, Professor Zong-Chao Yan from the University of New Brunswick, Canada, and Professor Shou-Gang Zhang from the National Time Service Centre, Chinese Academy of Sciences, welcome researchers in this field to join this event to share the latest findings and discoveries. This symposium will mainly discuss the new progress in the field of cold atom physics, which has become the cornerstone of cutting-edge precision measurement physics and time-frequency research. This Research Topic hosted in Frontiers in Physics will provide an opportunity to show the breakthrough in the aspect of precision measurement physics and time-frequency research. All attendees of the 9th International Symposium on Cold Atom Physics are welcome to submit high-quality manuscripts on this Research Topic. Contributions from other interested professionals are also welcome.
We welcome high-quality original research and review articles in the following areas (but not limited to).
• Cold atom physics;
