Description
Ideas originally developed for axion dark matter can be adopted to search for high-frequency gravitational waves. To illustrate this, I will discuss the Gertsenshtein effect, or the inter-conversion of gravitational waves into electromagnetic waves in the presence of external magnetic (or electric) fields. Exploiting the analogy with axions I will show that axion haloscopes based on lumped-element detectors can probe gravitational waves in the 100 kHz-100 MHz range. Finally, I will discuss the corresponding detection prospects of primordial-black-hole binaries. Based on 2202.00695 (accepted for publication in PRL) and Phys.Rev.Lett. 126 (2021) 2, 021104
