Relations Between Generalized JST Algorithm and Kalman Filtering Algorithm for Time Scale Generation
Yuyue Yan, Takahiro Kawaguchi, Yuichiro Yano +2
In this paper, we present a generalized Japan Standard Time algorithm (JST-algo) for higher-order atomic clock ensembles and mathematically clarify the relations of the (generalize…
Structured Kalman Filter for Time Scale Generation in Atomic Clock Ensembles
Yuyue Yan, Takahiro Kawaguchi, Yuichiro Yano +2
In this article, we present a structured Kalman filter associated with the transformation matrix for observable Kalman canonical decomposition from conventional Kalman filter (CKF)…
Higher-Order Allan Variance for Atomic Clocks of Arbitrary Order: Mathematical Foundation
Takayuki Ishizaki, Taichi Ichimura, Takahiro Kawaguchi +2
In this paper, we perform a time-domain analysis of the higher-order Allan variance for atomic clock models of arbitrary order. Adopting a standard atomic clock model where the tim…
Two-step pulse observation to improve resonance contrast for coherent population trapping atomic clock
Yuichiro Yano, Shigeyoshi Goka, Masatoshi Kajita
We study resonance contrast by a two-step pulse observation method to enhance the frequency stability of coherent population trapping (CPT) atomic clocks. The proposed method is a…
Two-step pulse observation for Raman-Ramsey coherent population trapping atomic clocks
Yuichiro Yano, Shigeyoshi Goka, Masatoshi Kajita
We propose a two-step pulse observation method to enhance frequency stability for coherent population trapping (CPT) atomic clocks. The proposed method is a Raman-Ramsey scheme wit…
High-contrast Coherent Population Trapping based on Crossed Polarizers Method
Yuichiro Yano, Shigeyoshi Goka
We developed a method based on crossed polarizers to observe high-contrast coherent population trapping (CPT) resonance. Since crossed polarizers have a simple optical system, our…
Theoretical and experimental investigation of the light shift in Ramsey coherent population trapping
Yuichiro Yano, Wujie Gao, Shigeyoshi Goka +1
The ac Stark shift (or light shift) of the 6S (F 3 4) transition in Cs, as observed through coherent population trapping under pulsed e…
