Description

The idea of searching for gravitational waves using cavities in strong magnetic fields has recently received significant attention. In particular, cavities with rather small volumes that are currently used to search for axion-like particles are discussed in this context. GravNet - the gravitational wave network - is an initiative to build a global network of detectors to search for high frequency gravitational waves. The first 3 detectors are currently under construction. Several sources of high frequency gravitational waves are discussed in new physics models, most prominently primordial black hole merges and axion super-radiance. Both production mechanisms lead to signals with distinct features. Challenges of detecting gravitational waves from both exemplary sources are discussed as well as prospects for the detection of GW using the network of RF cavity based detectors.
