Cs Atomic(铯原子)研究综述
Cs Atomic 铯原子 - Motivated by recent experiments on $^{6}$Li-$^{133}$Cs atomic mixtures with high mass imbalance, we study the Efimov correlation in atomic system of two heavy bosons ($^{133}$Cs) immersed in a bath of light fermions ($^{6}$Li). [1] For GPS satellites, the average standard deviations (STDs) of Cs atomic clocks will reach as high as 0. [2] The wavelength of our system is stabilized within transmission frequency region of 852 nm Faraday optical filter, and the peak of the transmission is corresponding to Cs atomic Doppler broadened line at the cell temperature of 41 $$^{\circ }$$C and the magnetic field of 330 G, making it suitable for laser-pumped Cs gas-cell and atomic beam frequency standard, etc. [3] We have designed a highly collimated collinear Rb/Cs atomic beam source device used in vacuum environment, which can be applied to both high-precision comparison measurement based on dual-atom system and dual clock. [4] As Cs is a line-poor system, only five usable Cs atomic emission lines could be found and characterised by employing high-resolution system. [5] To investigate the surface morphology as well as microstructural characteristics atomic force microscopy (AFM), transmission electron microscopy TEM, and x-ray diffraction (XRD) measurements were employed. [6] 1 to 6 kG, in which Cs atomic transitions are split into a large number of components, and FR signals of spectral width of ∼ 50 MHz are frequency-resolved allowing the investigation of individual transitions. [7] 5 mm − 1 by modulating the pump laser beam with a digital micromirror device and then obtain the SFR of a Cs atomic magnetometer by measuring the spin polarization of Cs at different spatial frequencies. [8] This definition of SI second is realized in practice using Cs atomic fountain primary frequency standard (PFS). [9]受最近对具有高质量不平衡的 $^{6}$Li-$^{133}$Cs 原子混合物的实验的启发，我们研究了两个重玻色子 ($^{133}$Cs) 在原子系统中的 Efimov 相关性。轻费米子浴 ($^{6}$Li)。 [1] 对于 GPS 卫星，铯原子钟的平均标准偏差（STDs）将高达 0。 [2] 我们系统的波长稳定在 852 nm 法拉第滤光片的透射频率范围内，透射峰值对应于电池温度 41 $$^{\circ }$$C 和 Cs 原子多普勒展宽线330 G的磁场，使其适用于激光泵浦Cs气室和原子束频率标准等。 [3] 我们设计了一种用于真空环境的高准直共线Rb/Cs原子束源装置，可应用于基于双原子系统和双时钟的高精度比对测量。 [4] 由于 Cs 是一个线差系统，因此通过采用高分辨率系统只能找到五个可用的 Cs 原子发射线并对其进行表征。 [5] 为了研究表面形态和微观结构特征，采用原子力显微镜 (AFM)、透射电子显微镜 TEM 和 X 射线衍射 (XRD) 测量。 [6] 1 到 6 kG，其中 Cs 原子跃迁被分成大量分量，光谱宽度为 ∼50 MHz 的 FR 信号是频率分辨的，允许研究单个跃迁。 [7] 5 mm - 1 通过用数字微镜器件调制泵浦激光束，然后通过测量不同空间频率下Cs的自旋极化获得Cs原子磁强计的SFR。 [8] SI 秒的这种定义在实践中使用 Cs 原子喷泉主频率标准 (PFS) 来实现。 [9]
