Dielectric Haloscopes as Gravitational Wave Detectors / Domcke, Valerie (CERN) ; Ellis, Sebastian A.R. (Geneva U., Dept. Theor. Phys.) ; Kopp, Joachim (CERN ; Mainz U.)
We argue that dielectric haloscopes like MADMAX, originally designed for detecting axion dark matter, are also very promising gravitational wave detectors. [...]

A novel search for high-frequency gravitational waves with low-mass axion haloscopes / Domcke, Valerie (CERN ; Ecole Polytechnique, Lausanne) ; Garcia-Cely, Camilo (DESY) ; Rodd, Nicholas L. (CERN)
Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of external electric and magnetic fields. We discuss this phenomenon with a particular focus on reinterpreting the results of axion haloscopes based on lumped-element detectors, which probe GWs in the 100 kHz-100 MHz range. [...]

Symmetries and Selection Rules: Optimising Axion Haloscopes for Gravitational Wave Searches / Domcke, Valerie (CERN) ; Garcia-Cely, Camilo (Valencia U., IFIC) ; Lee, Sung Mook (CERN ; IPAP, Seoul) ; Rodd, Nicholas L. (CERN)
In the presence of electromagnetic fields, both axions and gravitational waves (GWs) induce oscillating magnetic fields: a potentially detectable fingerprint of their presence. We demonstrate that the response is largely dictated by the symmetries of the instruments used to search for it. [...]

Magnets are Weber Bar Gravitational Wave Detectors / Domcke, Valerie (CERN) ; Ellis, Sebastian A.R. (Geneva U., Dept. Theor. Phys.) ; Rodd, Nicholas L. (LBL, Berkeley ; UC, Berkeley)
When a gravitational wave (GW) passes through a DC magnetic field, it couples to the conducting wires carrying the currents which generate the magnetic field, causing them to oscillate at the GW frequency. [...]

Potential of radio telescopes as high-frequency gravitational wave detectors / Domcke, Valerie (DESY ; CERN ; EPFL, Lausanne, LPPC) ; Garcia-Cely, Camilo (DESY)
In the presence of magnetic fields, gravitational waves are converted into photons and vice versa. We demonstrate that this conversion leads to a distortion of the cosmic microwave background (CMB), which can serve as a detector for MHz to GHz gravitational wave sources active before reionization. [...]

Search for a Dark-Matter-Induced Cosmic Axion Background with ADMX / ADMX Collaboration
We report the first result of a direct search for a Cosmic ${\it axion}$ Background (C$a$B) - a relativistic background of axions that is not dark matter - performed with the axion haloscope, the Axion Dark Matter eXperiment (ADMX). Conventional haloscope analyses search for a signal with a narrow bandwidth, as predicted for dark matter, whereas the C$a$B will be broad. [...]

Looking for MACHOs in the Spectra of Fast Radio Bursts / Katz, Andrey (CERN ; Geneva U., CAP) ; Kopp, Joachim (CERN ; U. Mainz, PRISMA) ; Sibiryakov, Sergey (CERN ; EPFL, Lausanne, LPPC ; Moscow, INR) ; Xue, Wei (CERN ; Florida U.)
We explore a novel search strategy for dark matter in the form of massive compact halo objects (MACHOs) such as primordial black holes or dense mini-halos in the mass range from $10^{-4}$ to 0.1 solar masses. These objects can gravitationally lens the signal of fast radio bursts (FRBs), producing a characteristic interference pattern in the frequency spectrum, similar to the previously studied femtolensing signal in gamma ray burst spectra. [...]

Design, development, and construction of the new beam stoppers for CERN's injector complex / Baillard, D. (CERN) ; Grenier-Boley, E. (CERN) ; Dole, M. (CERN) ; Deslande, F. (CERN) ; Froeschl, R. (CERN) ; Lorenzon, T. (CERN) ; Moyret, P. (CERN) ; Peron, R. (CERN) ; Pilan Zanoni, A. (CERN) ; Sharp, C. (CERN) et al.
Beam stoppers are installed in the transfer lines of the CERN accelerator complex; these components are used as part of the access safety system, which guarantees the safety of workers in the accelerators. [...]

Complexity Equals Anything? / Belin, Alexandre (CERN) ; Myers, Robert C. (Perimeter Inst. Theor. Phys.) ; Ruan, Shan-Ming (Perimeter Inst. Theor. Phys. ; Waterloo U. ; Kyoto U., Yukawa Inst., Kyoto) ; Sárosi, Gábor (CERN) ; Speranza, Antony J. (Perimeter Inst. Theor. Phys. ; Illinois U., Urbana)
We present a new infinite class of gravitational observables in asymptotically anti–de Sitter space living on codimension-one slices of the geometry, the most famous of which is the volume of the maximal slice. We show that these observables display universal features for the thermofield-double state: they grow linearly in time at late times and reproduce the switchback effect in shock wave geometries.
