Surpassing the Energy Resolution Limit with ferromagnetic torque sensors
Andrea Vinante, Chris Timberlake, Dmitry Budker +3
We discuss the fundamental noise limitations of a ferromagnetic torque sensor based on a levitated magnet in the tipping regime. We evaluate the optimal magnetic field resolution t…
Ferromagnetic Gyroscopes for Tests of Fundamental Physics
Pavel Fadeev, Chris Timberlake, Tao Wang +6
A ferromagnetic gyroscope (FG) is a ferromagnet whose angular momentum is dominated by electron spin polarization and that will precess under the action of an external torque, such…
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…
Ultralow mechanical damping with Meissner-levitated ferromagnetic microparticles
A. Vinante, P. Falferi, G. Gasbarri +3
Levitated nanoparticles and microparticles are excellent candidates for the realization of extremely isolated mechanical systems, with a huge potential impact in sensing applicatio…
Optimal control for feedback cooling in cavityless levitated optomechanics
Luca Ferialdi, Ashley Setter, Marko Toroš +2
We consider feedback cooling in a cavityless levitated optomechanics setup, and we investigate the possibility to improve the feedback implementation. We apply optimal control theo…
Static force characterization with Fano anti-resonance in levitated optomechanics
Chris Timberlake, Marko Toroš, David Hempston +3
We demonstrate a classical analogy to the Fano anti-resonance in levitated optomechanics by applying a DC electric field. Specifically, we experimentally tune the Fano parameter by…
