“…Our results highlight the importance to investigating the possibility of non-standard early cosmologies when considering the range of parameters consistent with cosmological observations. In the light of emerging experiments which can be used to probe axions in the ultra-light mass region, such as IAXO [35], CASPEr [36], ABRA-CADABRA [37], KLASH [38], DANCE [39], SHAFT [40] and MAGIS [41], our results…”

In the framework where the strong coupling is dynamical, the QCD sector may confine at a much higher temperature than it would in the Standard Model, and the temperature-dependent mass of the QCD axion evolves in a non-trivial way. We find that, depending on the evolution of ΛQCD, the axion field may undergo multiple distinct phases of damping and oscillation leading generically to a suppression of its relic abundance. Such a suppression could therefore open up a wide range of parameter space, resurrecting in particular axion dark-matter models with a large Peccei-Quinn scale fa ≫ 1012 GeV, i.e., with a lighter mass than the standard QCD axion.

“…For this reason it is crucial to have a preliminary characterization of the site at Fermilab to better understand the noise that will arise from temperature and pressure fluctuations, and seismic activity. MAGIS-100 aims to be a next generation probe for dark matter (DM), quantum effects, and gravitational waves (GWs) in the mid-band frequency range of 0.1-10 Hz [21][22][23]. The detector uses advances in atomic interferometry while simultaneously pushing the limits of baseline length, time duration, and large momentum transfer (LMT) [24][25][26][27][28][29][30][31][32].…”

We investigate and analyze site specific systematics for the MAGIS-100 atomic interferometry experiment at Fermi National Accelerator Laboratory. As atom interferometers move out of the laboratory environment passive and active mitigation for noise sources must be implemented. To inform the research and development of the experiment design, we measure ambient temperature, humidity, and vibrations of the installation site. We find that temperature fluctuations will necessitate enclosures for critical subsystems and a temperature controlled laser room for the laser system. We also measure and analyze the vibration spectrum above and below ground for the installation site. The seismic vibration effect of gravity gradient noise is also modeled using input from a low-noise seismometer at multiple locations and a mitigation scheme is studied using a stochastic simulation and characterized by a suppression factor.

“…It is anticipated that composite pulses [17] or pulses employing adiabatic rapid passage [16], or optimal quantum control [39], which makes the transfer efficiency less sensitive to Doppler and AC-Stark-shift induced detunings and Rabi frequency inhomogeneities, would further increase the peak enhancement in sensitivity. Moreover, the implementation of PSI in combination with spatially resolved phase detection offers the potential to characterize and mitigate laser-wavefront-induced phase errors [1,40]. These and other mitigation strategies will be explored in future work.…”

High Sensitivity Multi-Axes Rotation Sensing Using Large Momentum Transfer Point Source Atom Interferometry

A point source interferometer (PSI) is a device where atoms are split and recombined by applying a temporal sequence of Raman pulses during the expansion of a cloud of cold atoms behaving approximately as a point source. The PSI can work as a sensitive multi-axes gyroscope that can automatically filter out the signal from accelerations. The phase shift arising from the rotations is proportional to the momentum transferred to each atom from the Raman pulses. Therefore, by increasing the momentum transfer, it should be possible to enhance the sensitivity of the PSI. Here, we investigate the degree of enhancement in sensitivity that could be achieved by augmenting the PSI with large momentum transfer (LMT) employing a sequence of many Raman pulses with alternating directions. We analyze how factors such as Doppler detuning, spontaneous emission, and the finite initial size of the atomic cloud compromise the advantage of LMT and how to find the optimal momentum transfer under these limitations, with both the semi-classical model and a model under which the motion of the center of mass of each atom is described quantum mechanically. We identify a set of realistic parameters for which LMT can improve the PSI by a factor of nearly 40.
