Axionlike particles are compelling ultralight dark matter candidates that may couple weakly to photons and induce minute, time varying rotations of the polarization state of light. Cavity enhanced polarimetry offers a promising route to probing such effects by amplifying small polarization changes over many optical round trips. In particular, a Fabry Perot cavity containing two intracavity...

The ALPS group at DESY has constructed a unique infrastructure for tests of fundamental physics consisting of two strings of 12 HERA dipole magnets. Each string provides 5.3 T magnetic fields over a length of roughly 100 m with cleanrooms in between the magnet strings and at the ends of the experiment. This environment is particularly well suited for experiments that use laser interferometry,...

Ultralight vector dark matter is expected to form a coherent oscillating field that can generate tiny, periodic forces detectable by precision instruments. Our differential torsion sensor focuses on detecting differential accelerations between beryllium (Be) and aluminium (Al) test masses, materials chosen for their contrasting neutron-to-mass ratios. By measuring the differential...

The Axion Dark Matter eXperiment (ADMX) is a major haloscope experiment that has achieved DFSZ sensitivity at around 1 GHz. VERA (“Volume Enhanced Resonators for Axions”) is an ADMX high-frequency working group that explores new geometries for resonators with volumes far exceeding $\lambda^3$ ($V\gg \lambda^3$). The main objective is to extend ADMX's sensitivity to theoretically motivated...

DMRadio-50L is a lumped-element search for axion dark matter in the 5 kHz–5 MHz range, corresponding to axion masses of order 10⁻¹¹–10⁻⁸ eV. It combines a superconducting toroidal magnet, a high-Q tunable LC resonator, and a SQUID-based readout chain operating at mK temperatures to detect the narrowband electromagnetic response induced by axion dark matter.
This talk presents the first...

The TASEH experiment searches for the Axion Dark Matter with a Haloscope detector, featuring a high-quality-factor cavity with tunable resonance frequency in a uniform magnetic field. The whole setup is maintain at a temperature of few tens of miliKelvin in a Dilution Refrigerator. The system design follows the concept developed by Sikivie and pioneered by ADMX and Haystack experiments....

The use of travelling wave parametric amplifiers (TWPAs) represents a convenient and effective readout strategy for axion haloscope experiments. TWPAs produce many GHz of broadband gain, typically covering the entire range of an experimental run, with near-quantum-limited added noise that is increasingly competitive with that of their resonant, narrowband counterparts. Beyond low-noise...

QCD axions are expected to both mediate forces between nuclei and interact electromagnetically. Axion dark matter haloscope searches have exquisite sensitivity, but only to narrow bands of axion masses and rely on axions making up a known quantity of dark matter. 5th force experiments do not rely on dark matter and have a wide axion mass range, but are limited in coupling sensitivity. Is...
