Prospects for HFGW searches with the axion experiments ALPS II and BabyIAXO
/ Lindner, Axel (speaker)
At DESY in Hamburg, axions search experiments not relying on the dark matter paradigm are taking data (ALPS II) or have good prospects to start construction soon (BabyIAXO). Due to the similarity of axion-photon and GW-photon conversions in background magnetic fields, both experiments will also be sensitive to high frequency gravitational waves (HF-GW). [...]

Sensing High Frequency Gravitational Waves with Acoustic Resonators: an update on the MAGE experiment
/ Campbell, William (speaker)
The Multimode Acoustic Gravitational wave Experiment (MAGE) is a high frequency gravitational wave detection experiment [1] that utilises quartz bulk acoustic wave resonators as precision strain sensors. In its first stage, the experiment features two near-identical quartz bulk acoustic wave resonators that act as strain antennas with spectral sensitivity as low as $6.6\times 10^{-21}\left[\textrm{strain}\right]/\sqrt{\textrm{Hz}}$ in multiple narrow bands across MHz frequencies [...]

Partially-levitated membranes for high-frequency gravitational wave (HFGW) detection
/ Reinhardt, Christoph (speaker) (DESY)
Patterned thin films that are freely suspended from a silicon chip (i.e., membranes) are some of the lowest-loss mechanical oscillators.
As such, they provide an exceptional level of isolation from the noisy environment, similar to what has been achieved with levitated nanoparticles.
Here, I will present a concept for a HFGW detector, which corresponds to a Michelson interferometer with a membrane incorporated in each arm cavity.
In addition to explaining the underlying operating principle, I will provide details on achieving a sensitivity comparable to the target for the Levitated Sensor Detector, which relies on optically levitated stacks instead of membranes. (see dedicated talks).
In this regard, a particular focus will be on realizing suitable membranes, which requires significantly reducing their intrinsic loss..

High-Frequency Gravitational Waves in Electromagnetic Waveguides
/ Sorge, Francesco (speaker)
The interaction between a very-high-frequency gravitational wave (VHFGW) and an electromagnetic wave (EMW) in a rectangular waveguide is discussed in the weak field limit. The background EMW is assumed to be initially in the TE10 mode along the waveguide. [...]
