High-Frequency Gravitational Wave Constraints from Precision Spectroscopy
Dmitry Budker, Valerie Domcke, Joachim Kopp +1
Gravitational waves affect the propagation of electromagnetic waves in laser cavities, modulating the frequency of emitted photons. We use this effect to search for high-frequency…
Shielded inner-shell transitions in atomic samarium for tests of fundamental physics
R. Aramyan, D. Budker, V. A. Dzuba +5
Forbidden atomic transitions provide some of the most stringent low-energy tests of physics beyond the Standard Model, with sensitivity set by the interplay between the sought-for…
Global detector network to search for high-frequency gravitational waves (GravNet): conceptual design
Dorian Amaral, Diego Blas, Yuliia Borysenkova +30
We propose GravNet (Global detector network to search for high-frequency gravitational waves), a novel experimental scheme enabling the search for gravitational waves in the MHz to…
Second-order correlations in directed emissions in sodium atoms
Ara Tonoyan, Sushree Subhadarshinee Sahoo, Anahit Gogyan +4
We report on measurements of second-order intensity correlations of infrared emission under bichromatic excitation at 589.2\,nm and 569.0\,nm of sodium atoms contained…
Search for fast-oscillating fundamental constants with space missions
Dmitry Budker, Joshua Eby, Marianna S. Safronova +1
While it is possible to estimate the dark matter density at the Sun distance from the galactic center, this does not give information on actual dark matter density in the Solar sys…
Scalar dark matter induced oscillation of permanent-magnet field
I. M. Bloch, D. Budker, V. V. Flambaum +3
Scalar-field dark matter models imply small oscillations of fundamental constants. These oscillations could result in observable variations of the magnetic field in a permanent mag…
New Horizons: Scalar and Vector Ultralight Dark Matter
D. Antypas, A. Banerjee, C. Bartram +123
The last decade has seen unprecedented effort in dark matter model building at all mass scales coupled with the design of numerous new detection strategies. Transformative advances…
Improved bounds on ultralight scalar dark matter in the radio-frequency range
Oleg Tretiak, Xue Zhang, Nataniel L. Figueroa +5
We present a search for fundamental constant oscillations in the range ~kHz- MHz, that may arise within models for ultralight dark matter (UDM). Using two independent, sig…
Search for oscillations of fundamental constants using molecular spectroscopy
R. Oswald, A. Nevsky, V. Vogt +8
A possible implication of an ultralight dark matter (UDM) field interacting wibeginth the Standard Model (SM) degrees of freedom is oscillations of fundamental constants. Here, we…
Probing fast oscillating scalar dark matter with atoms and molecules
Dionysios Antypas, Oleg Tretiak, Ke Zhang +5
Light scalar Dark Matter with scalar couplings to matter is expected within several scenarios to induce variations in the fundamental constants of nature. Such variations can be se…
Continuous-Wave Cavity Ring-Down Polarimetry
Jim C. Visschers, Oleg Tretiak, Dmitry Budker +1
We present a new cavity-based polarimetric scheme for highly sensitive and time-resolved measurements of birefringence and dichroism, linear and circular, that employs rapidly-puls…
Polychromatic, continuous-wave mirrorless lasing from monochromatic pumping of cesium vapor
D. Antypas, O. Tretiak, D. Budker +1
We report on studies of simultaneous continuous-wave mirrorless lasing on multiple optical transitions, realized by pumping hot cesium vapor with laser light resonant with the 6$S_…
Scalar dark matter in the radio-frequency band: atomic-spectroscopy search results
D. Antypas, O. Tretiak, A. Garcon +3
Among the prominent candidates for dark matter are bosonic fields with small scalar couplings to the Standard-Model particles. Several techniques are employed to search for such co…

Oleg Tretiak, Peter Blümler, Lykourgos Bougas
We present a design for producing precisely adjustable and alternating single-axis magnetic fields based on nested Halbach dipole pairs consisting of permanent magnets only. Our de…
Eddy-current imaging with nitrogen-vacancy centers in diamond

We demonstrate microwave-free eddy-current imaging using nitrogen-vacancy centers in diamond. By detecting the eddy-current induced magnetic field of conductive samples, we can dis…
Raman and nuclear magnetic resonance investigation of alkali metal vapor interaction with alkene-based anti-relaxation coating
O. Yu. Tretiak, J. W. Blanchard, D. Budker +3
The use of anti-relaxation coatings in alkali vapor cells yields substantial performance improvements by reducing the probability of spin relaxation in wall collisions by several o…
