Cavity-enhanced spectroscopy in the deep cryogenic regime -- new hydrogen technologies for quantum sensing
Kamil Stankiewicz, Marcin Makowski, Michał Słowiński +13
Spectrometers based on high-finesse optical cavities have proven to be powerful tools for applied and fundamental studies. Extending this technology to the deep cryogenic regime is…
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…
Absolute frequency determination of molecular transition in the Doppler regime at kHz level of accuracy
K. Bielska, S. Wojtewicz, P. Morzynski +7
We present absolute frequency measurement of the unperturbed P7 P7 O B-band transition with relative standard uncertainty of . We reached the level of accuracy…
Searching for topological defect dark matter with optical atomic clocks
Piotr Wcislo, Piotr Morzynski, Marcin Bober +4
The total mass density of the Universe appears to be dominated by dark matter. However, beyond its gravitational interactions at the galactic scale, little is known about its natur…
Absolute measurement of the - clock transition in neutral Sr over the 330 km-long stabilized fibre optic link
Piotr Morzynski, Marcin Bober, Dobroslawa Bartoszek-Bober +14
We report a stability below of two independent optical lattice clocks operating with bosonic Sr isotope. The value (429228066418008.3(1.9)(…
Strontium optical lattice clocks for practical realization of the metre and secondary representation of the second
M. Bober, P. Morzyński, A. Cygan +17
We present a system of two independent strontium optical lattice standards probed with a single shared ultra-narrow laser. The absolute frequency of the clocks can be verified by t…
