“…(Taken from [371].) University of Western Australia -UWA) but also in Europe (QUAX [397,398] at INFN Legnaro) to extend the sensitivity of cavity experiments to mass ranges up to ∼70 µeV, maybe even beyond. These are mainly based on the challenging tasks of increasing magnetic field and volume [399,400], improving on detection technology to (sub) quantum limited detection of (quantum squeezed) signals in the 100 MHz to 10 GHz regime [401,402] and by increasing the Q-factor of cavities using superconducting foils [397,403] or using the dielectric cavity approach.…”

This Report provides an extensive review of the experimental programme of direct detection searches of particle dark matter. It focuses mostly on European efforts, both current and planned, but does it within a broader context of a worldwide activity in the field. It aims at identifying the virtues, opportunities and challenges associated with the different experimental approaches and search techniques. It presents scientific and technological synergies, both existing and emerging, with some other areas of particle physics, notably collider and neutrino programmes, and beyond. It addresses the issue of infrastructure in light of the growing needs and challenges of the different experimental searches. Finally, the Report makes a number of recommendations from the perspective of a long-term future of the field. They are introduced, along with some justification, in the opening Overview and Recommendations section and are next summarised at the end of the Report. Overall, we recommend that the direct search for dark matter particle interactions with a detector target should be given top priority in astroparticle physics, and in all particle physics, and beyond, as a positive measurement will provide the most unambiguous confirmation of the particle nature of dark matter in the Universe.

“…Recently, a new class of experiments has emerged, based on laser interferometry [45][46][47][48][49][50][51], where an optical cavity is used to measure the induced phase difference between two circularly-polarized modes in a laser beam due to the interaction with a background of ALP dark matter. Furthermore, ALPs may mediate shortrange spin dependent forces between spin polarized sources such as electron and nucleon [52][53][54][55][56][57][58]. Searching for ALPs in this manner is independent of the ALP DM density [59,60].…”

We propose an experiment for detecting Axion-Like Particles (ALPs) based on the axion-photon interaction in the presence of a non-uniform magnetic field. The impact of virtual ALPs on the polarization of the photons inside a cavity is studied and a detection scheme is proposed. We find that the cavity normal modes are dispersed differently owing to their coupling to the ALPs in the presence of a background magnetic field. This birefringence, in turn, can be observed as a phase difference between the cavity polarization modes. The signal is considerably enhanced for a squeezed light source. We argue that the amplified signal allows for exclusion of a range of axion mass 6 × 10-4 eV ≲ ma ≲ 6 × 10-3 eV even at very small axion-photon coupling constant with the potential to reach sensitivity to the QCD axion. Our scheme allows for the exclusion of a range of axion masses that has not yet been covered by other experimental techniques.

Dark matter from an even lighter QCD axion: trapped misalignment

We show that dark matter can be accounted for by an axion that solves the strong CP problem, but is much lighter than usual due to a Z N symmetry. The whole mass range from the canonical QCD axion down to the ultra-light regime is allowed, with 3 ≤ N 65. This includes the first proposal of a "fuzzy dark matter" QCD axion with m a ∼ 10 −22 eV. A novel misalignment mechanism occurs -trapped misalignment-due to the peculiar temperature dependence of the Z N axion potential. The dark matter relic density is enhanced because the axion field undergoes two stages of oscillations: it is first trapped in the wrong minimum, which effectively delays the onset of true oscillations. Trapped misalignment is more general than the setup discussed here, and may hold whenever an extra source of Peccei-Quinn breaking appears at high temperatures. Furthermore, it will be shown that trapped misalignment can dynamically source the recently proposed kinetic misalignment mechanism. All the parameter space is within tantalizing reach of the experimental projects for the next decades. For instance, even Phase I of CASPEr-Electric could discover this axion.
