Study of NbN as superconducting material for the usage in superconducting radio frequency cavities
Kristof Schmieden, Tim Schneemann, Matthias Schott +4
A new axion-haloscope is setup at the Johannes Gutenberg university of Mainz, named the Supax (a SUPerconducting AXion search) experiment. This setup is used to characterize the be…
Towards high-sensitivity magnetometry with nitrogen vacancy centers in diamond using the singlet infrared absorption
Ali Tayefeh Younesi, Muhib Omar, Arne Wickenbrock +2
The negatively-charged nitrogen vacancy (NV) center in diamond is widely used for quantum sensing since the sensitivity of the spin triplet in the electronic ground state to…
Temperature shift of magnetic-field-dependent photoluminescence features of nitrogen-vacancy ensembles in diamond
Irena Rodzoń, Xue Zhang, Viktor Ivády +3
Recently significant attention has been paid to magnetic-field-dependent photoluminescence (PL) features of the negatively charged nitrogen-vacancy (NV) centers in diamond. These f…
Microwave-free imaging magnetometry with nitrogen-vacancy centers in nanodiamonds at near-zero field
Saravanan Sengottuvel, Omkar Dhungel, Mariusz Mrózek +4
Magnetometry using Nitrogen-Vacancy (NV) color centers in diamond predominantly relies on microwave spectroscopy. However, microwaves may hinder certain studies involving biologica…
Searching for dark matter with a 1000 km baseline interferometer
Daniel Gavilan-Martin, Grzegorz Lukasiewicz, Mikhail Padniuk +8
Axion-like particles (ALPs) arise from well-motivated extensions to the Standard Model and could account for dark matter. ALP dark matter would manifest as a field oscillating at a…
A Multi-Messenger Search for Exotic Field Emission with a Global Magnetometer Network
Sami S. Khamis, Ibrahim A. Sulai, Paul Hamilton +38
Quantum sensor networks in combination with traditional astronomical observations are emerging as a novel modality for multi-messenger astronomy. Here we develop a generic analysis…
Near-zero-field microwave-free magnetometry with nitrogen-vacancy centers in nanodiamonds
Omkar Dhungel, Mariusz Mrózek, Till Lenz +6
We study the fluorescence of nanodiamond ensembles as a function of static external magnetic field and observe characteristic dip features close to the zero field with potential fo…
