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…
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…
