A nuclear clock synchronized to Th
Beichen Huang, Gaowei Yan, Qi Xiao +37
Atomic clocks have made time and frequency the most precisely measured quantities in physics, progressing from microwave standards that realize the SI second to optical clocks with…
A continuous-wave vacuum ultraviolet laser for the nuclear clock
Qi Xiao, Gleb Penyazkov, Xiangliang Li +14
The exceptionally low-energy isomeric transition in Th at around 148.4 nm offers a unique opportunity for coherent nuclear control and the realisation of a nuclear clock. R…
High-precision laser spectrum analyzer via digital decoherence
Zhongwang Pang, Chunyi Li, Hongfei Dai +5
With the continuous advancement of laser technology, accurately evaluating the noise spectrum of high-performance lasers has become increasingly challenging. In this work, we demon…
Highly coherent two-color laser with stability below 3E-17 at 1 second
Bibo He, Jiachuan Yang, Fei Meng +8
Two-color lasers with high coherence are paramount in precision measurement, accurate light-matter interaction, and low-noise photonic microwave generation. However, conventional t…
Observation of anomalous information scrambling in a Rydberg atom array
Xinhui Liang, Zongpei Yue, Yu-Xin Chao +4
Quantum information scrambling, which describes the propagation and effective loss of localinformation, is crucial for understanding the dynamics of quantum many-body systems. We r…
Absolute frequency measurements with a robust, transportable ^{40}Ca^{+} optical clock
Huaqing Zhang, Yao Huang, Baolin Zhang +9
We constructed a transportable 40Ca+ optical clock (with an estimated minimum systematic shift uncertainty of 1.3*10^(-17) and a stability of 5*10^(-15)/sqrt{tau} ) that can operat…
Development and Evaluation of a Narrow Linewidth Laser System for 171Yb+ E2 Transition
Yani Zuo, Shiying Cao, Shaoyang Dai +9
We report the construction and characterization of a narrow-linewidth laser system to interrogate the E2 clock transitions at 436 nm of ytterbium ions trapped in end-cap traps. The…
Inelastic collisions and density-dependent excitation suppression in a Sr optical lattice clock
Michael Bishof, Michael J Martin, Matthew D. Swallows +5
We observe two-body loss of Sr atoms trapped in a one-dimensional optical lattice. We measure loss rate coefficients for atomic samples between 1 and 6 K that…
Resolved atomic interaction sidebands in an optical clock transition
Michael Bishof, Yige Lin, Matthew D. Swallows +3
We report the observation of resolved atomic interaction sidebands (ISB) in the Sr optical clock transition when atoms at microkelvin temperatures are confined in a two-di…
Suppression of collisional shifts in a strongly interacting lattice clock
Matthew D. Swallows, Michael Bishof, Yige Lin +4
Optical lattice clocks have the potential for extremely high frequency stability owing to the simultaneous interrogation of many atoms, but this precision may come at the cost of s…
