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…
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…
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…
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…
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…
An experimental platform for levitated mechanics in space
Jack Homans, Elliot Simcox, Jakub Wardak +9
Conducting levitated mechanical experiments in extreme conditions has long been the aim of researchers, as it allows for the investigation of new fundamental physics phenomena. One…
Ultralight dark matter detection with levitated ferromagnets
Saarik Kalia, Dmitry Budker, Derek F. Jackson Kimball +7
Levitated ferromagnets act as ultraprecise magnetometers, which can exhibit high quality factors due to their excellent isolation from the environment. These instruments can be uti…
Levitated ferromagnetic magnetometer with energy resolution well below
Felix Ahrens, Wei Ji, Dmitry Budker +3
A quantum limit on the measurement of magnetic field has been recently pointed out, stating that the so-called Energy Resolution is bounded to $E_\mathrm{R} \gtrsim…
Nanoparticle Interferometer by Throw and Catch
Jakub Wardak, Tiberius Georgescu, Giulio Gasbarri +2
Matter-wave interferometry with increasingly larger masses could pave the way to understanding the nature of wavefunction collapse, the quantum to classical transition or even how…
Linear cooling of a levitated micromagnetic cylinder by vibration
Chris Timberlake, Elliot Simcox, Hendrik Ulbricht
We report feedback cooling of translational and librational degrees of freedom of a levitated micromagnet cylinder, utilizing a piezoelectric actuator to apply linear feedback to h…
Testing Dissipative Collapse Models with a Levitated Micromagnet
A. Vinante, G. Gasbarri, C. Timberlake +2
We present experimental tests of dissipative extensions of spontaneous wave function collapse models based on a levitated micromagnet with ultralow dissipation. The spherical micro…
Correlated random walks caused by dynamical wavefunction collapse
Daniel Bedingham, Hendrik Ulbricht
Wavefunction collapse models modify Schrödinger's equation so that it describes the collapse of a superposition of macroscopically distinguishable states as a dynamical process. Th…
