Engineering the sensitivity of macroscopic physical systems to variations in the fine-structure constant
Beata Zjawin, Marcin Bober, Roman Ciuryło +3
Experiments aimed at searching for variations in the fine-structure constant are based on spectroscopy of transitions in microscopic bound systems, such as atoms and ions, or r…
Ultra-high finesse cavity-enhanced spectroscopy for accurate tests of quantum electrodynamics for molecules
M. Zaborowski, M. Słowiński, K. Stankiewicz +11
We report the most accurate measurement of the position of the weak quadrupole S(2) 2-0 line in D. The spectra were collected with a frequency-stabilized cavity ring-down spect…
Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
First observation with global network of optical atomic clocks aimed for a dark matter detection
P. Wcisło, P. Ablewski, K. Beloy +19
We report on the first earth-scale quantum sensor network based on optical atomic clocks aimed at dark matter (DM) detection. Exploiting differences in the susceptibilities to the…
Dual Hg-Rb magneto-optical trap
Marcin Witkowski, Bartlomiej Nagoorny, Rodolfo Munoz-Rodriguez +6
We present a two-species laser cooling apparatus capable of simultaneously collecting Rb and Hg atomic gases into a magneto-optical trap (MOT). The atomic sources, laser system, an…
Weakly bound molecules as sensors of new gravitylike forces
Mateusz Borkowski, Alexei A. Buchachenko, Roman Ciuryło +5
Several extensions to the Standard Model of particle physics, including light dark matter candidates and unification theories, predict deviations from Newton's law of gravitation.…
