Supporting data for "A Prototype Atom Interferometer to Detect Dark Matter and Gravitational Waves"

Summary This is an archived copy of the data and code used to produce the results presented in the work “A Prototype Differential Atom Interferometer for Fundamental Physics”, stored on Zenodo under DOI:10.5281/zenodo.15166669. This repository contains the curated analysis inputs and experimental control code underlying the differential atom-interferometry measurements reported in the paper. In the manuscript, we compare Low Laser Noise (LLN) and High Laser Noise (HLN) operation, and we demonstrate the recovery of injected oscillatory signals over a wide frequency range. The data catalogue in this release is organised around those measurement configurations. The Imperial laboratory uses ARTIQ as an experimental control platform. To trace any processed dataset back to the experiment that produced it, this release includes the relevant ARTIQ run IDs (RIDs) and HDF5 data files in hdf5_data, together with a trimmed copy of the corresponding experiment code in icl_experiments. Note: Analysis code and processed datasets are archived separately in DOI:10.5281/zenodo.19592552 - these are almost certainly more useful for most readers, so you should start there. Data - hdf5_data The file experiment_rids.yml is the index of the experimental runs used in the paper’s analysis, which are included as HDF5 files. Each top-level YAML key names a dataset family. Most entries contain a single scan parameter and a list of RIDs; where more than one parameter setting is associated with the same family, the file uses an entries list. The LLN/HLN comparison used for the differential-phase stability analysis is stored under with_phi_hln-lnl-repeat. This has two entries with the same RID set and different noise_amplitude values: noise_amplitude: 0 for the Low Laser Noise dataset. noise_amplitude: 2 for the High Laser Noise dataset, corresponding to the phase-randomised operating regime discussed in the paper. The signal-injection datasets used to test recovery of oscillatory differential signals are grouped by injected signal frequency: signal-0_1mHz: signal_amplitude: 0.6, RIDs [63483, 63489, 63668, 63667] signal-0_3mHz: signal_amplitude: 0.6, RIDs [63846, 63845, 63844, 63866, 63868, 63867] signal-1mHz: two entries, signal_amplitude: 0.3 and signal_amplitude: 1.2, both with RIDs [62068, 62069, 62070, 62145] signal-1mHz-again: signal_amplitude: 0.6, RIDs [65278] signal-3mHz: signal_amplitude: 0.6, RIDs [63900, 63902, 63901] signal-10mHz: signal_amplitude: 0.6, RIDs [64979] signal-30mHz: signal_amplitude: 0.6, RIDs [65093] signal-100mHz: signal_amplitude: 0.6, RIDs [64835] These run groups correspond to the measurements used for the likelihood-based signal-recovery studies described in the paper. Together they cover the representative frequency range from 0.1 mHz to 100 mHz, as well as the repeated 1 mHz measurements used for amplitude studies. The RID list is intended to provide provenance for the processed datasets bundled elsewhere in this release. In particular, data_analysis/data/ contains the derived CSV, NPY and NPZ files used for figure generation, while hdf5_data/experiment_rids.yml records which ARTIQ runs contributed to those products. Code - icl_experiments and data_analysis The full icl_experiments repository is available open-source at https://gitlab.com/aion-physics/code/artiq/experiment-repositories/icl_experiments. Various commits of this repostory were used to produce the datasets above - the HDF5 files contain a commit hash that can be used to replicate the exact version for any given dataset. In this archived repository, only the files relevant to the presented experiment are retained. The experiment implementation included here is repository/clock_interferometry/clock_interferometry_from_xodt.py/DifferentialClockInterferometryWithNoiseAndSignal, which combines the differential clock interferometer sequence with both injected laser-noise and injected signal capabilities. The directory data_analysis contains the stripped-down analysis code and bundled derived data used to reproduce the figures in the paper. This includes the notebooks for the black-hole sensitivity projection and for the differential interferometer analyses, together with the precomputed data products needed to run them without access to the laboratory data store.
