Heterodyne dispersive cavity ring-down spectroscopy exploiting eigenmode frequencies for high-fidelity measurements
Agata Cygan, Szymon Wójtewicz, Hubert Jóźwiak +6
Measuring low light absorption with combined uncertainty < 1 permille is crucial in a wide range of applications. Popular cavity ring-down spectroscopy can provide ultra-high preci…
Line-shape study of CO perturbed by N with mid-infrared frequency comb-based Fourier-transform spectroscopy
Akiko Nishiyama, Grzegorz Kowzan, Dominik Charczun +3
We developed a mid-infrared optical frequency comb-based Fourier-transform spectrometer and performed a line-shape study of the fundamental vibrational band of CO perturbed by N${_…
CIRCUS: an autonomous control system for antimatter, atomic and quantum physics experiments
Marco Volponi, Saiva Huck, Ruggero Caravita +49
A powerful and robust control system is a crucial, often neglected, pillar of any modern, complex physics experiment that requires the management of a multitude of different device…
Positronium laser cooling via the - transition with a broadband laser pulse
L. T. Glöggler, N. Gusakova, B. Rienäcker +49
We report on laser cooling of a large fraction of positronium (Ps) in free-flight by strongly saturating the - transition with a broadband, long-pulsed 243 nm alexandri…
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…
Sub-promille measurements and calculations of CO (3--0) overtone line intensities
K. Bielska, A. A. Kyuberis, Z. D. Reed +11
Intensities of lines in the near-infrared second overtone band (3--0) of CO are measured and calculated to an unprecedented degree of precision and accuracy. Agreemen…
