Optically Derived Radio-Frequency Benchmark in Methanol: A Sub-kHz Reference for Astrophysical Tests of Fundamental Physics
Frank M. J. Cozijn, Arthémise Altman, Alexandr S. Bogomolov +8
Methanol radio lines observed in space provide sensitive probes of whether the proton-to-electron mass ratio has changed over cosmic time, but such tests require laboratory rest fr…
Quasi-continuous sub-K strontium source without a high-finesse cavity stabilized laser
Sana Boughdachi, Benedikt Heizenreder, Ananya Sitaram +8
We demonstrate a quasi-continuous sub-K strontium source achieved without the use of a high-finesse cavity-locked laser. Our frequency reference is based on a dispersion-optimiz…
Ultrastable optical frequency dissemination over a branching passive optical network using CDMA
Rodrigo González Escudero, Sougandh Kannoth Mavila, Jeroen C. J. Koelemeij
We demonstrate a technique for ultrastable optical frequency dissemination in a branching passive optical network using code-division multiple access (CDMA). In our protocol, each…
A hybrid optical-wireless network for decimetre-level terrestrial positioning
J. C. J. Koelemeij, H. Dun, C. E. V. Diouf +3
Global navigation satellite systems (GNSS) are widely used for navigation and time distribution, features indispensable for critical infrastructure such as mobile communication net…
Extraction of spin-averaged rovibrational transition frequencies in HD for the determination of fundamental constants
Jean-Philippe Karr, Jeroen C. J. Koelemeij
We present a comprehensive analysis of all currently available high-accuracy frequency measurements of rotational and rovibrational transitions in the hydrogen molecular ion HD…
Self-consistent extraction of spectroscopic bounds on light new physics
Cédric Delaunay, Jean-Philippe Karr, Teppei Kitahara +3
Fundamental physical constants are determined from a collection of precision measurements of elementary particles, atoms and molecules. This is usually done under the assumption of…
