“…For example, in the case of non-relativistic non-clustered neutrinos and approximating LIGO's mirrors as 40 kg pure silicon, we find 5) which is right within the LIGO sensitivity band. However, as we will see in the next section, the corresponding acceleration of a G 2 F = 7.3 · 10 −32 cm/s 2 for silicon is very far beyond the current reach of LIGO.…”

The cosmic neutrino background is a key prediction of Big Bang cosmology which has not been observed yet. The movement of the earth through this neutrino bath creates a force on a pendulum, as if it were exposed to a cosmic wind. We revise here estimates for the resulting pendulum acceleration and compare it to the theoretical sensitivity of an experimental setup where the pendulum position is measured using current laser interferometer technology as employed in gravitational wave detectors. We discuss how a significant improvement of this setup can be envisaged in a micro gravity environment. The proposed setup could also function as a dark matter detector in the sub-MeV range, which currently eludes direct detection constraints.

“…Similar to the experiment proposed in [44] to search for ultralow-mass scalar and vector dark matter, a torque due to the oscillating axion field appears at six different frequencies corresponding to the combination of the axion frequency ν a ¼ m a /2π, the turntable frequency ν TT , and the Earth rotation frequency ν ⊕ ,…”

“…It is interesting to note axions with even lighter masses below 10 −22 eV can also form a partial contribution to the total dark-matter mass density [61,62]. This extreme ultralight dark matter has been the focus of several recent experimental proposals [42][43][44][46][47][48][49][50], but most have focused on scalar dark matter and its couplings. In this paper, we present several experiments that can be modified or created to search for axions at the lightest masses, and evaluate their potential to reach axion couplings several orders of magnitude beyond current astrophysical bounds.…”

Axionlike particles are promising candidates to make up the dark matter of the Universe, but it is challenging to design experiments that can detect them over their entire allowed mass range. Dark matter in general, and, in particular, axionlike particles and hidden photons, can be as light as roughly 10 −22 eV (∼10 −8 Hz), with astrophysical anomalies providing motivation for the lightest masses ("fuzzy dark matter"). We propose experimental techniques for direct detection of axionlike dark matter in the mass range from roughly 10 −13 eV (∼10 2 Hz) down to the lowest possible masses. In this range, these axionlike particles act as a time-oscillating magnetic field coupling only to spin, inducing effects such as a timeoscillating torque and periodic variations in the spin-precession frequency with the frequency and direction of these effects set by the axion field. We describe how these signals can be measured using existing experimental technology, including torsion pendulums, atomic magnetometers, and atom interferometry. These experiments demonstrate a strong discovery capability, with future iterations of these experiments capable of pushing several orders of magnitude past current astrophysical bounds.

“…Additionally, the new light field couples to matter through its mixing with the Higgs boson and so mediates a new force. It may be possible to design new high-precision experiments to search for these phenomena [50]. Such searches will be quite challenging.…”

A new class of solutions to the electroweak hierarchy problem is presented that does not require either weak-scale dynamics or anthropics. Dynamical evolution during the early Universe drives the Higgs boson mass to a value much smaller than the cutoff. The simplest model has the particle content of the standard model plus a QCD axion and an inflation sector. The highest cutoff achieved in any technically natural model is 10 8 GeV.
