Search for ultralight dark matter with spectroscopy of radio-frequency atomic transitions
Xue Zhang, Abhishek Banerjee, Mahapan Leyser +4
The effects of scalar and pseudoscalar ultralight bosonic dark matter (UBDM) were searched for by comparing the frequency of a quartz oscillator to that of a hyperfine-structure tr…
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…
Precision determination of isotope shifts in ytterbium and implications for new physics
N. L. Figueroa, J. C. Berengut, V. A. Dzuba +3
We report measurements of isotope shifts for the five spinless Yb isotopes on the transition using Doppler-free two-photon s…
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…
Fast apparent oscillations of fundamental constants
Dionysios Antypas, Dmitry Budker, Victor V. Flambaum +3
Precision spectroscopy of atoms and molecules allows one to search for and to put stringent limits on the variation of fundamental constants. These experiments are typically interp…
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…
Isotopic variation of parity violation in atomic ytterbium: method of measurements and analysis of systematic effects
D. Antypas, A. M. Fabricant, J. E. Stalnaker +3
We present a detailed description of experimental studies of the parity violation effect in an isotopic chain of atomic ytterbium (Yb), whose results were reported in a recent Lett…
Dependence of atomic parity-violation effects on neutron skins and new physics
A. V. Viatkina, D. Antypas, M. G. Kozlov +2
We estimate the relative contribution of nuclear structure and new physics couplings to the parity non-conserving spin-independent effects in atomic systems, for both single isotop…
All-Optical Spin Locking in Alkali-Vapor Magnetometers
Guzhi Bao, Dimitra Kanta, Dionysios Antypas +5
The nonlinear Zeeman effect can induce splittings and asymmetries of magnetic-resonance lines in the geophysical magnetic-field range. We demonstrate a scheme to suppress the nonli…
Lineshape-asymmetry elimination in weak atomic transitions driven by an intense standing wave field
Dionysios Antypas, Anne Fabricant, Dmitry Budker
Owing to the ac-Stark effect, the lineshape of a weak optical transition in an atomic beam can become significantly distorted, when driven by an intense standing wave field. We use…
