Search for non-Newtonian interactions at micrometer scale with a levitated test mass
Charles P. Blakemore, Alexander Fieguth, Akio Kawasaki +5
We report on a search for non-Newtonian forces that couple to mass, with a characteristic scale of m, using an optically levitated microsphere as a precision force sens…
Entanglement-Enhanced Optical Atomic Clock
Edwin Pedrozo-Peñafiel, Simone Colombo, Chi Shu +8
State-of-the-art atomic clocks are based on the precise detection of the energy difference between two atomic levels, measured as a quantum phase accumulated in a given time interv…
Evidence for Nonlinear Isotope Shift in Yb Search for New Boson
Ian Counts, Joonseok Hur, Diana P. L. Aude Craik +7
We measure isotope shifts for five Yb isotopes with zero nuclear spin on two narrow optical quadrupole transitions , ${}^2S_{1/2} \rightarr…
High sensitivity, levitated microsphere apparatus for short-distance force measurements
Akio Kawasaki, Alexander Fieguth, Nadav Priel +3
A high sensitivity force sensor based on dielectric microspheres in vacuum, optically trapped by a single, upward-propagating laser beam, is described. Off-axis parabolic mirrors a…
Trapping Yb Atoms into a One-Dimensional Optical Lattice with a Small Waist
Akio Kawasaki, Boris Braverman, Edwin Pedrozo-Peñafiel +4
In most experiments with atoms trapped in optical lattices, the transverse size of the optical lattice beams is on the order of tens of micrometers, and loading many atoms into sma…
Absolute pressure and gas species identification with an optically levitated rotor
Charles P. Blakemore, Denzal Martin, Alexander Fieguth +4
The authors describe a novel variety of spinning-rotor vacuum gauge in which the rotor is a m-diameter silica microsphere, optically levitated. A rotating elec…
