Solid-state nuclear magnetic resonance search for axion-like dark matter with broadband SQUID magnetometry
Andrew J. Winter, János Ádám, Deniz Aybas +5
We report the results of an experimental search for ultralight axion-like dark matter in the mass ranges 19.5--20.5 and 21.5--22 neV. The Cosmic Axion Spin Precession Experiment-el…
Control of relaxation properties of a macroscopic nuclear spin ensemble
János Ádám, Andrew J. Winter, Deniz Aybas +4
Macroscopic spin ensembles in solids are powerful platforms for quantum sensing and precision metrology. A key challenge is controlling the nuclear spin population relaxation time…
Floquet engineering of spin-spin interactions in a hybrid atomic system
Daniel Gavilan-Martin, Grzegorz Łukasiewicz, Vincent Schäfer +8
We demonstrate dynamical control of the effective spin-spin interaction, dominated by Fermi-contact interaction, in a hybrid spin system via parametric modulation. We show that, in…
Magnetic Microscopy of Skyrmions in Magnetic Thin Films with Chiral Overlayers
Buddhika Hondamuni, Théo Balland, Fabian Kammerbauer +15
Topologically nontrivial magnetic textures such as skyrmions offer promising opportunities for spintronic applications. In recent years, it has been shown that the magnetic propert…
First Axion Search Results of the SUPAX Prototype Experiment
Tim Schneemann, Hendrik Bekker, Dmitry Budker +4
The SUPerconduction AXion search experiment (Supax) is a future haloscope-type detector designed to probe axion-like particles (ALPs) as candidates for dark matter and solutions to…
Black hole scalar sirens in the Milky Way
Daniel Gavilan-Martin, Olivier Simon, Dhashin Krishna +3
Hypothetical light scalar particles trigger the superradiant instability around spinning black holes (BHs), causing clouds of scalars to grow around the BH. In the presence of suff…
Cavity, lumped-circuit, and spin-based detection of axion dark matter: differences and similarities
Deniz Aybas, Hendrik Bekker, Dmitry Budker +12
Axions and axion-like particles are compelling candidates for ultralight bosonic dark matter, forming coherent oscillating fields that can be probed by experiments known as halosco…
Human Cardiac Measurements with Diamond Magnetometers
Muhib Omar, Magnus Benke, Shaowen Zhang +27
We demonstrate direct, non-invasive and non-contact detection of human cardiac magnetic signals using quantum sensors based on nitrogen-vacancy (NV) centers in diamond. Three confi…
Zero- to low-field J-spectroscopy with a diamond magnetometer
Muhib Omar, Jingyan Xu, Raphael Kircher +8
We report measurements of zero- to ultra-low-field nuclear magnetic resonance (ZULF NMR) signals at frequencies of a few hertz with a diamond-based magnetic sensor. The sensing dia…
