Quantum Materials and Devices for Dark Matter Detection

Astronomical and cosmological observations show that dark matter is a major component of the Universe, yet its microscopic nature remains unknown. Searches are increasingly turning toward lowmass particles, axions, and other wave-like candidates that may produce only a few excitations or an extremely weak coherent signal.

The material in which an interaction occurs, the excitation that carries the signal, and the device used to read it out must be considered together. Superconductors, topological and magnetic materials, and low-dimensional systems offer new possibilities as absorbers and transducers.

At the same time, microwave cavities, superconducting circuits, qubits, electromechanical systems, and low-temperature calorimeters are approaching the sensitivity required to detect individual photons, quasiparticles, or very small energy deposits, creating new opportunities for dark matter searches.

This seminar will bring together researchers in dark matter physics, quantum materials, and quantum devices to examine the path from microscopic interaction to material response and quantum-limited readout. Related rare-event searches will be included selectively where they provide transferable detector concepts or measurement strategies relevant to dark matter detection.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
