The haloscope is one of the most sensitive approaches to the QCD axion physics within the region where the axion is considered to be a dark matter candidate. Current experimental sensitivities, which rely on the lowest fundamental TM010 mode of a cylindrical cavity, are limited to relatively low mass regions. Exploiting higher-order resonant modes would be beneficial because it will enable us to extend the search range with no volume loss and higher quality factors. This approach has been…

Dielectric-Boosted Sensitivity to Cylindrical Azimuthally Varying Transverse-Magnetic Resonant Modes in an Axion Haloscope

Axions are a popular dark matter candidate which are often searched for in experiments known as ``haloscopes" which exploit a putative axion-photon coupling. These experiments typically rely on

Search for Invisible Axion Dark Matter with a Multiple-Cell Haloscope.

The first results of a search for invisible axion dark matter using a multiple-cell cavity haloscope are presented, demonstrating the novelty of the cavity concept for high-mass axion searches and suggesting it can make considerable contributions to the next-generation experiments.

A first proof of principle booster setup for the MADMAX dielectric haloscope

Axions and axion-like particles are excellent low-mass dark matter candidates. The MADMAX experiment aims to directly detect galactic axions with masses between 40 and $$400\,\upmu \mathrm{eV}$$ 400

Sensitivity improvement in hidden photon detection using resonant cavities

Analogous to the light-shining-through-wall setup proposed for axion-like particle searches, a pair of resonant cavities have been considered to search for an extra U(1) massive gauge boson, called a

Discovering QCD-Coupled Axion Dark Matter with Polarization Haloscopes

In the presence of QCD axion dark matter, atoms acquire time-dependent electric dipole moments. This effect gives rise to an oscillating current in a nuclear spin-polarized dielectric, which can

Development of a cavity with photonic crystal structure for axion searches

Two cavities of different sizes with a photonic crystal structure have been developed for axion searches. In the cavities, the dispersion relation in the photonic crystal is utilized, and so they

Invisible axion search methods

Originally hypothesized to explain the absence of $C\phantom{\rule{0}{0ex}}P$ violation in the strong interactions, the axion has emerged as a candidate constituent of dark matter. This review guides



Tunable Supermode Dielectric Resonators for Axion Dark-Matter Haloscopes

We present frequency tuning mechanisms for dielectric resonators, which undergo "super-mode" interactions as they tune. The tunable schemes are based on dielectric materials strategically placed

Search for Invisible Axion Dark Matter with the Axion Dark Matter Experiment.

This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81  μeV, achieving unprecedented sensitivity by operating a large-volume haloscope at subkelvin temperatures, thereby reducing thermal noise as well as the excess noise from the ultralow-noise superconducting quantum interference device amplifier used for the signal power readout.

Axion Research at CAPP/IBS

The axion, a hypothetical fundamental particle, was postulated as an attractive solution to the CP problem in quantum chromodynamics and believed to be an ideal candidate for the cold dark matter.

Microwave cavity searches for dark-matter axions

Recent determinations of cosmological parameters point to a flat Universe, whose total energy density is composed of about two-thirds vacuum energy and one-third matter. Ordinary baryonic matter is
