Resonant heterodyne conversion applied to a low-frequency haloscope for dark matter axion searches in the 1-35 MHz range
Jose R. Navarro-Madrid, José Reina-Valero, Alejandro DÃaz-Morcillo +1
We study resonant heterodyne up-conversion in the RADES-BabyIAXO haloscope as a method to search for low-mass dark matter axions using microwave cavities. Starting from axion elect…
Enhancement of dark-photon haloscope sensitivity with degenerate modes: toward axion-level form factor and polarization determination
Jose R. Navarro-Madrid, José Reina-Valero, Alejandro DÃaz-Morcillo +1
The dark photon has been postulated as a potential constituent of dark matter, exhibiting notable similarities to the axion. The primary distinction between the two particles lies…
Multiple-cavities interferometric analysis for dark matter axions directional-sensitive search based on signal cross-correlation processing
José Reina-Valero, Alejandro DÃaz-Morcillo, Benito Gimeno +5
Current axion detection limits neglect the relevance of the relative velocity between the axion field and the detectors. However, this aspect can lead to a daily modulation of the…
Dark Matter Axion Detection with Neural Networks at Ultra-Low Signal-to-Noise Ratio
José Reina-Valero, Alejandro DÃaz-Morcillo, José Gadea-RodrÃguez +5
We present the first analysis of Dark Matter axion detection applying neural networks for the improvement of sensitivity. The main sources of thermal noise from a typical read-out…
