Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

Probing an atomic resonance without disturbing it is an ubiquitous issue in physics. This
problem is critical in high-accuracy spectroscopy or for the next generation of atomic optical …

We experimentally investigate an optical frequency standard based on the 467 nm (642
THz) electric-octupole reference transition S 1/2 2 (F= 0)→ F 7/2 2 (F= 3) in a single trapped …

Neutral quantum absorbers in optical lattices have emerged as a leading platform for
achieving clocks with exquisite spectroscopic resolution. However, the studies of these …

We present a detailed experimental and theoretical study of the effect of nuclear spin on the
performance of optical lattice clocks. With a state-mixing theory including spin-orbit and …

We present nonstandard optical Ramsey schemes that use pulses individually tailored in
duration, phase, and frequency to cancel spurious frequency shifts related to the excitation …

We experimentally investigate a recently proposed optical excitation scheme VI Yudin et
al.[Phys. Rev. A 82, 011804 (R)(2010)] that is a generalization of Ramsey's method of …

We report what we believe to be the first accuracy evaluation of an optical lattice clock based
on the S01--> P03 transition of an alkaline earth boson, namely, Sr88 atoms. This transition …

In this paper we propose to utilize the X 2 Σ g (ν, N, F, M)=(0, 0, 1/2,±1/2)→(1, 0, 1/2,±1/2) or
(2, 0, 1/2,±1/2) transition of N 2+(I= 0) to test variations of the proton-to-electron mass ratio …

We review advances in the field of coherent population trapping (CPT) over the last decade
with respect to the application of this physical phenomenon to atomic frequency references …
