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…
Robust kHz-linewidth distributed Bragg reflector laser with optoelectronic feedback
Megan Yamoah, Boris Braverman, Edwin Pedrozo-Peñafiel +3
We demonstrate a combination of optical and electronic feedback that significantly narrows the linewidth of distributed Bragg reflector lasers (DBRs). We use optical feedback from…
Measurement of the Newtonian Constant of Gravitation by Precision Displacement Sensors
Akio Kawasaki
The Newtonian constant of gravitation historically has the largest relative uncertainty over all other fundamental constants with some discrepancies in values between different…
Precision Mass and Density Measurement of Individual Optically Levitated Microspheres
Charles P. Blakemore, Alexander D. Rider, Sandip Roy +4
We report an mass measurement of approximately-m-diameter, optically levitated microspheres with an electrostatic co-levitation technique. The mas…
Near-Unitary Spin Squeezing in Yb
Boris Braverman, Akio Kawasaki, Edwin Pedrozo-Peñafiel +9
Spin squeezing can improve atomic precision measurements beyond the standard quantum limit (SQL), and unitary spin squeezing is essential for improving atomic clocks. We report sub…
