Morning 4: Session 4
- Mihaela Parvu (Faculty of Physics, University of Bucharest)
In recent years, we witnessed an increasing growth in the research of light Dark Matter (DM) candidates, addressing in particular axions and axion-like particles (ALPs).
The axion observation technique is based upon its in- verse Primakoff conversion into one photon, stimulated by a static magnetic field.
Here, recent results of the QUAX experiment are presented.
In particular, the...
MADMAX, the MAgnetized Disc and Mirror Axion eXperiment, is a novel dielectric haloscope concept to detect the axion in the mass range 40-400 ueV through enhancement of the inverse Primakoff process. In this overview talk, I will review the experiment's design concept and discuss the status of ongoing research on the critical path of the experiment, including advancements in magnet...
Ultra-light axions is one of the most widely considered models of dark matter. In my talk, I will focus on the formation of cosmic web, first structures, stars and galaxies in a fuzzy dark matter universe. We model star and galaxy formation using a hydrodynamical code AREPO coupled to the ultra-light dark matter component solved using Schrodinger-Poisson code. We explore properties of the...
Axions and other light pseudoscalar bosons with masses below $1\,\mathrm{eV}/c^2$, collectively referred to as axionlike particles (ALPs), are among the most well-motivated dark matter (DM) candidates.
The Cosmic Axion Spin Precession Experiment (CASPEr)\,[1] aims at detecting axionlike DM with nuclear magnetic resonance techniques.
CASPEr-Gradient in Mainz probes the coupling of nuclear...
We present the status and recent results of the room temperature BREAD gigahertz pilot experiment (GigaBREAD) which is looking for axion-like particles in the $\sim 50 \ \mu\mathrm{eV}$ range. Reflector-based searches allow for wave-like dark matter searches at higher mass regimes where resonant cavity searches lose sensitivity due to scaling limitations. BREAD is a novel reflector concept...
The sexaquark, a hypothetical stable and neutral six-quark state, has been recently proposed as a dark matter candidate. Here, I argue it is very unlikely sexaquarks could consistently compose more than a billionth of the dark matter abundance for a wide range of scattering cross sections and annihilation rates. To draw these conclusions, I connect the sexaquark freeze-out abundance to...
In this presentation I will provide an update on research at the Quantum Technologies and Dark Matter Laboratories at the University of Western Australia to develop new techniques to search for wave-like dark matter candidates and to test fundamental physics using precision low-energy metrology.
In particular we will focus on techniques which utilize low-loss and low-noise electromagnetic...
