Evidence for parity violation in gravitational fields
V. Gharibyan, V. Adler, P. D. Allfrey +28
Discrete symmetries in gravity have only been tested for low energy, non-relativistic matter, confirming the perfectly symmetric general relativity. A hint for high energy $\cal{CP…
Sensitivity of a closed dielectric haloscope to axion dark matter
A. Ivanov, D. Leppla-Weber, B. Ary dos Santos Garcia +40
We present a method to determine the sensitivity of a closed dielectric haloscope to axion dark matter. Dielectric haloscopes aim to probe the theoretically well-motivated axion ma…
Design and construction of a cryogenic subcooler-box for supplying single phase supercritical helium to dark matter and gravitational wave experiments
Udai Raj Singh, Rajinikumar Ramalingam, Christoph Reinhardt +4
We report on the design, development, and installation of the ALPS Cryo-Platform Subcooler Box (ACPS), which is part of the cryogenic platform being established in the HERA North H…
Any Light Particle Searches with ALPS II: first science results
Daniel C. Brotherton, Zachary R. Bush, Sandy Croatto +37
The light-shining-through-a-wall experiment ALPS II at DESY in Hamburg searched for axions and similar lightweight particles in its first science campaign from February to May 2024…
The International Axion Observatory (IAXO): case, status and plans. Input to the European Strategy for Particle Physics
A. Arcusa, S. Ahyoune, K. Altenmuller +120
The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions with unprecedented sensitivity. IAXO holds a unique position in…
An accurate solar axions ray-tracing response of BabyIAXO
S. Ahyoune, K. Altenmueller, I. Antolin +124
BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion heliosc…
First search for axion dark matter with a Madmax prototype
B. Ary dos Santos Garcia, D. Bergermann, A. Caldwell +34
This paper presents the first search for dark matter axions with mass in the ranges 76.56 to 76.82 eV and 79.31 to 79.53 eV using a prototype setup for the MAgnetized Disk an…
First search for dark photon dark matter with a MADMAX prototype
J. Egge, D. Leppla-Weber, S. Knirck +43
We report the first result from a dark photon dark matter search in the mass range from to with a dielectric haloscope prototype for MADMAX (Magn…
First mechanical realization of a tunable dielectric haloscope for the MADMAX axion search experiment
The MADMAX Collaboration, B. Ary Dos Santos Garcia, D. Bergermann +36
MADMAX, a future experiment to search for axion dark matter, is based on a novel detection concept called the dielectric haloscope. It consists of a booster composed of several die…
Measurement of the thermal accommodation coefficient of helium on a crystalline silicon surface at low-temperatures
Alexander Franke, Nils Sültmann, Christoph Reinhardt +5
Next-generation gravitational wave observatories are expected to use cryogenically cooled, pendulum-suspended 200 kg test mass mirrors from a crystalline material such as crystalli…
Self-calibrating gas pressure sensor with a 10-decade measurement range
Christoph Reinhardt, Hossein Masalehdan, Sandy Croatto +6
Recent years have seen a rapid reduction in the intrinsic loss of nanomechanical resonators (i.e., chip-scale mechanical oscillators). As a result, these devices become increasingl…
Qualification of piezo-electric actuators for the MADMAX booster system at cryogenic temperatures and high magnetic fields
E. Garutti, H. Janssen, D. Kreikemeyer-Lorenzo +5
We report on the qualification of a piezo-based linear stage for the manipulation of positions of dielectric discs in the booster of the MADMAX axion dark matter search experiment.…

We present 3D calculations for dielectric haloscopes such as the currently envisioned MADMAX experiment. For ideal systems with perfectly flat, parallel and isotropic dielectric di…
Gas cooling of test masses for future gravitational-wave observatories
Christoph Reinhardt, Alexander Franke, Jörn Schaffran +2
Recent observations made with Advanced LIGO and Advanced Virgo have initiated the era of gravitational-wave astronomy. The number of events detected by these "2nd Generation" (2G)…
