“…The BPM framework may be straightforwardly applied to future data from ADMX [19], HAYSTAC [26], and other haloscopes and similar dark matter searches [3,[29][30][31][32][33][34][35][36]46]. We expect that BPM will probe deeper couplings at no experimental cost while permitting experimentalists to operate nimbly, without the more strict constraints of preordained scan protocols.…”

In experiments searching for axionic dark matter, the use of the standard threshold-based data analysis discards valuable information. We present a Bayesian analysis framework that builds on an existing processing protocol [1] to extract more information from the data of coherent axion detectors such as operating haloscopes. The analysis avoids logical subtleties that accompany the standard analysis framework and enables greater experimental flexibility on future data runs. Performing this analysis on the existing data from the HAYSTAC experiment, we find improved constraints on the axion-photon coupling gγ while also identifying the most promising regions of parameter space within the 23.15-24.0 µeV mass range. A comparison with the standard threshold analysis suggests a 36% improvement in scan rate from our analysis, demonstrating the utility of this framework for future axion haloscope analyses.

“…Later, it was noted that axions and axionlike particles (ALP) are perfect candidates be the dark matter component [31]. Despite numerous experiments to search for ALPs [32][33][34][35][36][37][38][39][40][41][42][43][44], it has not been reliably detected. As it was noted in Refs.…”

“…Tabletop experiments have expanded the range of constraints, particularly in the light mass ( 1 meV) and macroscopic length ( 0.2 mm) range. Examples of these experiments include nuclear magnetic resonance spectroscopy [9][10][11][12], spin-polarized torsion pendulum measurements [13][14][15][16], atomic beam spectroscopy [17,18], and ultracold molecular spectroscopy [19,20].…”

For decades, searches for exotic spin interactions have used increasingly-precise laboratory measurements to test various theoretical models of particle physics. However, most searches have focused on interaction length scales of 1 mm, corresponding to hypothetical boson masses of 0.2 meV. Recently, quantum sensors based on Nitrogen-Vacancy (NV) centers in diamond have emerged as a promising platform to probe spin interactions at the micrometer scale, opening the door to explore new physics at this length scale. Here, we propose experiments to search for several hypothetical interactions between NV electron spins and moving masses. We focus on potential interactions involving the coupling of NV spin ensembles to both spin-polarized and unpolarized masses attached to vibrating mechanical oscillators. For each interaction, we estimate the sensitivity, identify optimal experimental conditions, and analyze potential systematic errors. Using multi-pulse quantum sensing protocols with NV spin ensembles to improve sensitivity, we project new constraints that are 5 orders-of-magnitude improvement over previous constraints at the micrometer scale. We also identify a spin-polarized test mass, based on hyperpolarized 13 C nuclear spins in a thin diamond membrane, which offers a favorable combination of high spin density and low stray magnetic fields. Our analysis is timely in light of a recent preprint [1] reporting a surprising non-zero result of µm-scale spin-velocity interactions.
