    1. 27. Towards a Tunable and Modular Qubit-Based Haloscope with Vertical-Cut Cavities
      Dr Jose Maria Garcia Barcelo
      04/09/2026, 09:30

      Superconducting qubits and microwave photon counting offer a promising route towards quantum-enhanced axion searches, but efficient frequency scanning over a broad range remains a major challenge. We investigate a modular haloscope architecture combining a fixed readout cavity and transmon-based detection with elongated storage cavities employing vertical-cut tuning. This approach enables...

    2. 28. Strongly tunable YIG gyromagnetic modes for dark matter search
      Jeanne Bally
      04/09/2026, 09:50

      We propose a paradigm for quantum enhanced axion dark matter search, which does not rely on power measurements. We propose to measure directly the axion amplitude and phase in an interferometric protocol at the quantum limit, using a non-linear cavity. In addition, we introduce gyromagnetic modes as wide mass range transducers for axion signals compatible with standard haloscope designs. We...

    3. 29. Heterodyne detection applied to the RADES-BabyIAXO haloscopes
      Jose Ramón Navarro Madrid
      04/09/2026, 10:10

      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 electrodynamics, we derive the axion-induced source term and the power extracted through a readout mode, explicitly accounting for the finite axion linewidth. This leads to effective quality factors that determine the...

    4. 43. Recent Progress in HTS REBCO Coatings for the RADES Haloscope
      Irfan Ahmed (ICMAB-CSIC)
      04/09/2026, 10:30

      This report summarizes our recent progress on high-temperature superconducting (HTS) REBCO coatings for the RADES axion dark matter search. We present an optimized coating procedure based on a delamination technique that exposes the superconducting layer directly to the RF field, improving the cavity quality factor.To assess the mechanical reliability of the coating, we carried out adhesion...
