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…

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…

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…
