Superfluid He-4 as Dark Matter Detectors
Zizhou Huang, Mihaela Parvu, Dmitry Budker +2
Superfluid helium-4 is an attractive medium for high-sensitivity detection of dark matter (DM) candidates (as well as other particles). There are several collaborations that have b…
Generation of continuous-wave laser light at 148.4 nm using cavity-enhanced second harmonic generation in
Keerthan Subramanian, Hiroki Tanaka, Simon J. Herr +22
We experimentally investigate the potential of crystals to create a continuous-wave (CW) solid state laser at the vacuum ultraviolet (VUV) wavelength of 148.4 nm via cavi…
Ferromagnetic broadband sensing of axionlike dark matter
Chenhao Peng, Dmitry Budker, Yuanning Gao +6
Levitated particles have demonstrated ultrahigh sensitivity to magnetic fields and accelerations owing to their extremely low dissipation. Such systems have strong potential for fu…
Microwave-free vector magnetometry and crystal orientation determination with Nitrogen-Vacancy centers using Bayesian inference
Hilario Espinós, Omkar Dhungel, Arne Wickenbrock +3
Nitrogen-vacancy (NV) centers in diamond provide a solid-state platform for quantum sensing. While optically detected magnetic resonance techniques offer high sensitivity, their re…
Control of relaxation properties of a macroscopic nuclear spin ensemble
János Ãdám, 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 Åukasiewicz, 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…
