Search for ultralight dark matter from long-term frequency comparisons of optical and microwave atomic clocks
Takumi Kobayashi, Akifumi Takamizawa, Daisuke Akamatsu +8
We search for ultralight scalar dark matter candidates that induce oscillations of the fine structure constant, the electron and quark masses, and the quantum chromodynamics energy…
Librational Feedback Cooling
Charles P. Blakemore, Denzal Martin, Alexander Fieguth +4
Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the c…
Evidence of Two-Source King Plot Nonlinearity in Spectroscopic Search for New Boson
Joonseok Hur, Diana P. L. Aude Craik, Ian Counts +12
Optical precision spectroscopy of isotope shifts can be used to test for new forces beyond the Standard Model, and to determine basic properties of atomic nuclei. We measure isotop…
