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…
Acceleration sensing with magnetically levitated oscillators above a superconductor
Chris Timberlake, Giulio Gasbarri, Andrea Vinante +2
We experimentally demonstrate stable trapping of a permanent magnet sphere above a lead superconductor, in vacuum pressures of ~mbar. The levitating magnet behave…
Characterization of Non-linearities through Mechanical Squeezing in Levitated Optomechanics
Ashley Setter, Jamie Vovrosh, Hendrik Ulbricht
We demonstrate a technique to estimate the strength of non-linearities present in the trapping potential of an optically levitated nanoparticle. By applying a brief pulsed reductio…
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…
