Abstract：Devolop the analysis techniques in optical frequency standards and the approach of high-precision spectroscopy calculations. Find out the physical sources and limits of the errors in the high-precision spectroscopy experiments. Demonstrate the inner mechanics and limits of the quantum noises in the optical frequency standards system and explore effective methods to beat the traditional quantum limit. Give some understanding of many-body quantum effects and develop the new methods to manipulate many-body quantum effects in the optical frequency standard system. Search for the new approach for laser cooling and manipulation. Explore the theoretical and experimental probability of novel optical frequency standards in atomic ensembles system with many-body quantum effects.

Key Words：Optical frequency standards； Many-body quantum effect； High-precision spectroscopy
