A Levitated-Magnet Vector Force Sensor for Spin-Dependent Exotic Interactions
Dorian W. P. Amaral, Lei Cong, Tim M. Fuchs +2
We present a magnetically levitated ferromagnetic vector force sensor that enables selective searches for spin-dependent exotic interactions mediated by beyond-Standard-Model boson…
Detection of the Earth Tides by Diamagnetic Levitation
Tim M. Fuchs, Elliot Simcox, Michael Hawker +2
The detection of mass distributions and mass transport via gravity mapping is a key geophysical tool for understanding the structure and dynamics of the earth. Changes in mass dist…
Magnetic Levitation as a New Probe of Non-Newtonian Gravity
Dorian W. P. Amaral, Tim M. Fuchs, Hendrik Ulbricht +1
We present MORRIS (Magnetic Oscillatory Resonator for Rare-Interaction Studies) and propose the first tabletop search for non-Newtonian gravity due to a Yukawa-like fifth force usi…
Macroscopic Quantum Resonators Path Finder (MAQRO-PF) White Paper
Jack Homans, Laura da Palma Barbara, Jakub Wardak +3
Optically levitated particles are used in a wide range of experiments to explore both fundamental physics and to act as sensors to a variety of external forces. One field of partic…
Oligonucleotide selective detection by levitated optomechanics
Timothy Wilson, Owen J. L. Rackham, Hendrik Ulbricht
This study examines the detection of oligonucleotide-specific signals in sensitive optomechanical experiments. Silica nanoparticles were functionalized using ZnCl and 25-mers o…
Cryogenic pressure sensing with an ultrafast Meissner-levitated microrotor
Joel K Jose, Andrea Marchese, Marion Cromb +5
Magnetically levitated spinning rotors are key elements in important technologies such as navigation by gyroscopes, energy storage by flywheels, ultra-high vacuum generation by tur…
