International Optical Clock Comparison Using the European Optical Fiber Network
Marco Pizzocaro, Clara Zyskind, Anne Amy-Klein +41
Optical clocks have achieved remarkable estimated fractional frequency uncertainties reaching the level and below, enabling applications in fundamental physics, general…
A High-frequency Geodetic VLBI Experiment for Optical Clock Comparison
Monia Negusini, Myoung-Sun Heo, Cecilia Clivati +40
An intercontinental metrological clock comparison between Italy and the Republic of Korea was performed by means of geodetic K-band VLBI observations. The comparison involved the h…
Atomic thermometry in optical lattice clocks
Irene Goti, Tommaso Petrucciani, Stefano Condio +3
Accurate measurement of atomic temperature is fundamental for a wide range of applications, from quantum sensing to precision metrology. In optical lattice clocks, precise characte…
Coordinated international comparisons between optical clocks connected via fiber and satellite links
Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62
Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…
