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 …

A transportable optical clock based on the 4s 2 S 1/2-3d 2 D 5/2 electric quadrupole
transition at 729 nm of a single 40 Ca+ ion trapped in a mini Paul trap has been developed …

We report on the first absolute transition frequency measurement at the 10-15 level with a
single, laser-cooled Ca+ 40 ion in a linear Paul trap. For this measurement, a frequency …

An ion trap of the end-cap design was built recently at the National Research Council of
Canada for improved control of the 88 Sr+ single-ion optical frequency standard systematic …

Accelerating displacements preceding some catastrophic landslides have been found to
display a finite time singularity of the velocity v∼ 1/(tc− t)[Voight, 1988a, 1988b]. Here we …

This second volume of the Charged Particle Traps deals with the rapidly expanding body of
research exploiting the electromagnetic confinement of ions, whose principles and …

A fundamental limit to the stability of a single-ion optical frequency standard is set by
quantum noise in the measurement of the internal state of the ion. We discuss how the …

A systematic study of Ca+ atomic properties is carried out using a high-precision relativistic
all-order method where all single, double, and partial triple excitations of the Dirac-Fock …

High-resolution molecular spectroscopy is a sensitive probe for violations of fundamental
symmetries. Symmetry violation searches often require, or are enhanced by, the application …
