  1. 39. The Piezoaxionic Effect
    Amalia Madden (Perimeter Institute)

    Talk

    Axion dark matter (DM) constitutes an oscillating background that violates parity and time-reversal symmetries. Inside piezoelectric crystals, where parity is broken spontaneously, this axion background can result in a mechanical stress. We call this new phenomenon "the piezoaxionic effect". When the frequency of axion DM matches the natural frequency of a bulk acoustic normal mode of the...

  2. 27. First constraints on axion-like particles from Galactic sub-PeV gamma rays
    Christopher Eckner (LAPTh, CNRS)

    Talk

    Experimental refinements and technical innovations in the field of extensive air shower telescopes have enabled measurements of Galactic cosmic-ray interactions in the sub-PeV (100 TeV to 1 PeV) range, providing new avenues for the search for new physics and dark matter. For the first time, we exploit sub-PeV (from 10 TeV to 1 PeV) observations of Galactic diffuse gamma rays by

    Talk

    We present the current status and future plans of the various experiments within The Oscillating Resonant Group AxioN (ORGAN) Collaboration, which develops microwave cavity axion haloscopes. 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...

  4. 16. Gravitational Focusing of Dark Matter Streams in Solar Neighborhood and Implications for Detection
    Abaz Kryemadhi (Messiah University)
    09/08/2022, 15:40
    Talk

    Cosmological models of dark matter in the galaxy reveal more intricate features than a smooth standard Halo model. One of the features is the existence of numerous fine-grained streams at the location of the solar system, where these fine-grained streams have small velocity dispersion owing to the cold non-interacting nature of dark matter. The gravitational focusing of dark matter by the...

  5. 65. Dark Matter Radio Cubic Meter
    Maria Simanovskaia (Stanford University)
    11/08/2022, 14:00
    Talk

    The QCD axion, originally proposed as a solution to the strong CP problem in QCD, is one of the most strongly motivated candidates for dark matter. In this talk, I will describe a suite of experiments referred to as the Dark Matter Radio that search for the coupling of axionic dark matter to electromagnetism at masses below 1 $\mu$eV. Axions at these lower mass ranges can naturally be produced...

  6. 36. Cosmological constraints on decaying axion-like particles: a global analysis
    Sebastian Hoof (Georg-August-Universität Göttingen)
    11/08/2022, 15:40
    Talk

    Future cosmological probes promise significant progress in probing the dark universe and the related fundamental particles. Their impact is most powerful when we combine cosmological data with astrophysical observations and laboratory experiments. While computational tools are available for such studies, the large number of model parameters and ensuring consistency between data sets can...
