This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

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 …

We search for ultralight scalar dark matter candidates that induce oscillations of the fine
structure constant, the electron and quark masses, and the quantum chromodynamics …

We simultaneously measure the gravitationally induced phase shift in two Raman-type
matter-wave interferometers operated with laser-cooled ensembles of Rb 87 and K 39 …

Fundamental constants are a cornerstone of our physical laws. Any constant varying in
space and/or time would reflect the existence of an almost massless field that couples to …

We use 6 yrs of accurate hyperfine frequency comparison data of the dual rubidium and
caesium cold atom fountain FO2 at LNE-SYRTE to search for a massive scalar dark matter …

In a fibre-based quantum information network, telecom-wavelength transmission between
quantum memory elements is required to minimize absorption. Owing to the paucity of …

The gravitational couplings of matter are studied in the presence of Lorentz and CPT
violation. At leading order in the coefficients for Lorentz violation, the relativistic quantum …

We give an overview of the work done with the Laboratoire National de Metrologie et
d'Essais-Systemes de Reference Temps-Espace (LNE-SYRTE) fountain ensemble during …

The S 0 1-P 0 3 clock transition frequency ν Sr in neutral Sr 87 has been measured relative
to the Cs standard by three independent laboratories in Boulder, Paris, and Tokyo over the …
