A nuclear clock based on Th
Beichen Huang, Gaowei Yan, Qi Xiao +35
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 that…
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…
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…
