DarkSide-20k is a next-generation direct dark matter search experiment under construction at the Gran Sasso National Laboratory (LNGS) in Italy. The core of the detector is a two-phase liquid argon time projection chamber designed to probe WIMP interactions down to the neutrino floor, with an exposure goal of ~200 tonne-years in expectation of a WIMP-nucleon cross section of 10^-47 cm2 for a...

COSINE-100 is a NaI dark matter detection experiment located at the Yangyang Underground Laboratory in South Korea, designed with the main goal of testing the controversial, positive dark matter signal from the DAMA experiments using the same target material. COSINE-100 has been operational for almost six years and in that time has been the first NaI experiment to exclude the DAMA signal in...

The NEWS-G collaboration is searching for light dark matter using spherical proportional counters. Access to the mass range from 50 MeV to 10 GeV is enabled by the combination of low energy threshold, light gaseous targets (H, He, Ne), and highly radio-pure detector construction. The NEWS-G collaboration has constructed a new, 140 cm in diameter, spherical proportional counter at LSM using 4N...

The LUX-ZEPLIN (LZ) direct dark matter detection experiment is currently operating at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. LZ recently set new limits on WIMP-nucleus interactions above 9 GeV/c^2 with its first science run (SR1). This talk will detail these results, the status and outlook of the project.

I present an update on the work of the Quantum Sensing for the Hidden Sector collaboration, who are designing and building detectors for wave-like dark matter, particularly axions in the first instance, in the UK.

The toolkit of quantum technologies developed in atomic, molecular and optical physics are ideally suited to enhance the search for dark matter axions with masses above ~40 µeV. I will present an overview of a new experimental effort at Imperial College, developing technologies to initially target an axion mass range 120-250 µeV. We will use a large mode area Fabry-Perot cavity to efficiently...

Several independent observations suggest that there is more mass in the Universe than has been directly observed. Dark matter is a hypothetical new form of matter that does not interact with the electromagnetic field and has a very weak interaction with ordinary baryonic matter. WIMPs (weakly interacting massive particles) are a dark matter candidate currently widely investigated in...

The BREAD Collaboration proposes a novel dish antenna programme for broadband searches of terahertz axion dark matter. Its hallmark is a cylindrical metal barrel converting axions to photons that are focused by a parabolic reflector onto ultralow-noise quantum sensors. We present the BREAD conceptual design and science program from dark photon pilot planned at Fermilab to large-scale...

I introduce the Atom Interferometer Observatory and Network (AION), an experimental programme which aims to use cold strontium atoms to search for ultra-light dark matter and to explore gravitational waves. I outline the experimental concept of AION, and its place within the landscape of ultra-light dark matter detectors. Finally, I give progress update for the AION project in the UK, which is...

Levitated optomechanics provides a novel platform to test fundamental physics. One such application provides a unique directional dark matter direct detection technique to explore alternative parameter space to that being investigated by large scale experiments deployed underground. We detail our experiment, capable of resolving collisions in all three dimensions, utilising nanoparticles...

Previous calculations of the Migdal effect assumed small values of the nuclear recoil velocity and were limited to the ionisation of single electrons. I will discuss new calculations of the Migdal effect that are robust for any conceivable value of the nuclear recoil velocity and allow for the ionisation of multiple electrons. Our results enable robust predictions of the Migdal effect...

Liquid noble direct dark matter detection experiments aim to detect galactic dark matter scattering off nuclei in highly sensitive detectors in underground laboratories. As positive signals of dark matter in the lab are elusive, it is crucial that current and future experiments broaden the reach and scope of dark matter models which are explored. In this presentation I will report on work...

The non-thermal production of dark matter (DM) usually requires very tiny couplings of the dark sector with the visible sector and therefore is notoriously challenging to hunt in laboratory experiments. Here we propose a novel pathway to test such a production in the context of a non-standard cosmological history, using both gravitational wave (GW) and laboratory searches. We investigate the...
