Searching for dark matter with a spin-based interferometer
No full textName/institution/contact information for: Principal Investigator (or person responsible for collecting the data): Arne Wickenbrock / Johannes Gutenberg University in Mainz / [email protected] Data manager or custodian: Daniel Gavilan-Martin / Johannes Gutenberg University in Mainz / [email protected], Grzegorz Łukasiewicz / Jagiellonian University / [email protected] Methodology: This is experimental data related to the article 'Searching for dark matter with a spin-based interferometer' (https://doi.org/10.48550/arXiv.2408.02668). The data consists of discrete Fourier transforms of 25-h long time series recorded by self-compensating K-Rb-3He comagnetometers in Kraków, Poland and Mainz, Germany. The spectra are calibrated assuming neutron coupling referring to Table 1 in Mikhail Padniuk's et al. article 'Response of atomic spin‑based sensors to magnetic and nonmagnetic perturbations' (https://doi.org/10.57903/UJ/J33SMI). Calibration function parameters are also available in each file. Description of methods used for collection/generation of data: Each file corresponds to 25 h long dataset collected by comagnetometer sensor in Kraków, Poland and Mainz, Germany and has been already preprocessed according to description in Methods section of the article. Calibration: In order to recalibrate the data please use the 'calibration' group in h5 file and refer to the methodology described in Mikhail Padniuk's et al. paper 'Response of atomic spin‑based sensors to magnetic and nonmagnetic perturbations' (https://doi.org/10.57903/UJ/J33SMI) and the related repository (https://uj.rodbuk.pl/dataset.xhtml?persistentId=doi:10.57903/UJ/J33SMI). File name structure: Krakow.zip and Mainz.zip - correspond to data collected in Krakow and Mainz respectively. .h5 files containing 'freq (Hz)' and 'neutron-calibrated fft (pT)' datasets as well as 'calibration' group. Filename correspond to unix timestamps. neutron_limits.txt - final ALP-neutron limits (from Fig. 4
