Detecting high-frequency gravitational waves (HFGWs) encounters challenges due to smaller interferometers and weaker astrophysical sources. A promising homodyne detector utilizes the inverse Gertsenshtein effect, where HFGWs convert to photons in a magnetic field. A physical analysis highlights intrinsic noise and other complications. Dark matter (DM) axions can similarly be detected through the inverse Primakoff effect. Although not directly detected yet, axions are anticipated to produce stronger coherent signals and would additionally solve the strong charge-parity problem in QCD. Current detection mechanisms struggle at THz frequencies due to complex mechanical tuning and a lack of low-loss THz materials. The proposed THz-Radiometer for AXions (T-RAx) leverages recent advancements in semiconductor quantum structures, with electromagnetically tunable resonance frequencies, to target the THz (meV) axion. COMSOL simulations show significant enhancements of the axion-induced photons, optimistically reaching the QCD axion parameter space.","abstract_html":"Gravitational waves have been directly detected at sub-kHz frequencies.
