Cosmology has advanced from "2.5 facts" in 1963 to a very data-rich field today. This has led to the determination of the baryon density, the dark matter density, and the dark energy density. But more facts lead to a greater reliance on advanced statistical techniques, which are usually useful but occasionally misleading. It is important to consider "look elsewhere effects", and to remember...

In the regime of linear growth of structure, dark matter dominates structure formation at all scales. On small scales, the thermal and kinetic properties of dark matter will alter the growth of structure at a finite scale that depends on the nature of dark matter. I will review the methods for constraining matter clustering on small scales, highlighting those most robust to modeling and data...

Sterile neutrinos are a natural extension of the Standard Model of particle physics. If their mass is in the keV range, they are a viable dark matter candidate. One way to search for sterile neutrinos in a laboratory-based experiment is via tritium beta decay, where they would manifest themselves as a characteristic spectral distortion. The direct neutrino mass experiment, KATRIN, provides...

Sterile neutrino of keV-scale mass is one of strong dark matter candidates. One of the ways for observing “sterile” neutrino is using nuclear beta decays. Non-zero mixing of sterile neutrino to electron neutrino allows them being emitted in nuclear beta decays, which modifies the shape of beta decay spectrum by adding a 4-th spectral component with reduced end-point energy. This modification...

We will introduce new cosmological dynamics of the QCD axion, where the axion field rotates in field space. Axion dark matter may be produced from the kinetic energy of the rotation and the required axion decay constant is much below the prediction of the conventional evolutions. The angular momentum of the rotation is transferred into baryon asymmetry through baryon number violating...

In most direct detection experiments, the free nuclear recoil description of dark matter scattering breaks down for masses ≲ 100 MeV, or when the recoil energy is comparable to a few times the typical phonon energy. For dark matter lighter than 1 MeV, scattering via excitation of a single phonon dominates and has been computed previously, but for the intermediate mass range or higher detector...

Light thermal dark matter, whose mass is below 1GeV, is an attractive candidate for dark matter, as its abundance in the present universe is well explained by the thermal freeze-out mechanism. At the same time, it may solve the so-called core-cusp problem via its strong enough self-scattering. We study a minimal model for a light scalar dark matter as an example of such a candidate, requiring...

We propose a novel technique to search for axions with an optomechanical cavity filled with a material such as superfluid helium.

The axion absorption rate is enhanced by the high occupation number of coherent photons or phonons in the cavity, allowing our proposal to largely overcome the extremely small axion coupling....

ORGAN is a collaboration of various nodes of the ARC Centres of Excellence for Engineered Quantum Systems, and Dark Matter Particle Physics, and is primarily hosted at the University of Western Australia....

Among the theoretical particles that could explain dark matter, axions make an ideal candidate. They can be produced in the early Universe and make up the observed abundances, permeating the universe as an invisible wave. In recent years, the efforts to build a kind of radio that would tune to this unique frequency has intensified, with conventional techniques failing to look for high...

The QUest for Axion (QUAX) is a direct-detection CDM axion search which reaches the sensitivity necessary for the detection of galactic QCD-axion in the range of frequency 8.5-11 GHz. The QUAX collaboration is operating two haloscopes, located at LNL- and LNF-INFN laboratories in Italy, that work in synergy and operate in different mass ranges. In this talk we will report about results...

The Windchime Project seeks to exploit advances in quantum sensing technologies in order to search for dark matter in the laboratory, based on its gravitational interaction alone. The Planck mass (~10^19 GeV or 20 micrograms) is a particularly well-motivated mass range to search for dark matter. At this mass, the dark matter flux at Earth is still large enough to be experimentally accessible,...

The TESSERACT project will search for sub-GeV dark matter via multiple complementary advanced, ultra-sensitive phonon detectors, sensitive to nuclear-type, electron-type, and dark photon-type DM interactions, using targets of liquid helium (HeRALD) and the polar crystals GaAs and Sapphire (SPICE). Those detectors will share identical readout and experimental settings. Besides maximizing...

We report recent progress toward using superfluid 4He for nuclear recoil direct detection, as part of the overall TESSERACT pre-Project R&D effort. The quantum evaporation signal pathway allows both a low threshold and the possibility of rejecting the primary low-energy background (heat-only events in the calorimetry itself) through multi-channel coincidence. We have recently demonstrated...

TASEH (Taiwan Axion Search Experiment with Haloscope) devotes to search dark matter axions based on a haloscope setup, consisting of a frequency-tunable microwave cavity detector in a strong magnetic field and a readout amplification chain. The TASEH experiment targets axion searches in the mass range of 10–25 μeV, roughly corresponding to the frequency band of 2.5–6 GHz. In this presentation,...

We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program. This haloscope plans to search for bosonic dark matter across the [10−3, 1] eV ([0.24, 240] THz) mass range. BREAD proposes a cylindrical metal barrel to convert dark matter into photons, which a novel parabolic reflector design focuses onto a photosensor. This unique geometry...

Data from astrophysics and cosmology point to the existence of Cold Dark Matter in the Universe, for which a light axion is a well-motivated candidate. The HAYSTAC Experiment (Haloscope At Yale Sensitive To Axion CDM) is a microwave cavity search for axions with masses above 10 $\mu$eV/c$^2$. HAYSTAC, now in its second iteration, Phase II, employs squeezed state receiver to achieve sub-quantum...

The properties of dark matter halos and subhalos on scales below 10^9 solar masses depend on the formation mechanism, mass, and possible interactions of the dark matter particle. As such, inferences of the halo mass function and the internal structure of dark halos on these scales can be interpreted in the context of fundamental dark matter physics. I will discuss how effects such as...

Prof. Yanou Cui (University of California, Riverside)Axions, Alps, Wisps as dark matterTalk
While most searches for cosmic axions so far focused on their cold relics as (a component of) dark matter, various well-motivated cosmological sources can produce ``boosted'' axions that remain relativistic today. In this talk I will demonstrate that existing/upcoming neutrino experiments such as Super-Kamiokande, Hyper-Kamiokande, DUNE, JUNO, and IceCube can probe such energetic axion relics....

Over the past several decades, the dual-phase xenon time projection chamber (TPC) has risen to the forefront of the race to directly detect dark matter (DM). The technology utilizes photomultiplier tubes (PMTs), or other light detection devices, to readout scintillation produced promptly after a particle scatters in the liquid and electroluminescence generated when electrons freed by the...

Nuova Officina Assergi (NOA) is a Clean Room (CR) - classification ISO6 according to the ISO 14644-1 standard, intended for the construction and assembly of advanced electronic devices. This facility arises as a fundamental part of the Dark side-20K project and it has been realised thanks to two Italian government fundings called “Piano Operativo Nazionale 2014-2020” (PON) and “Programma di...
