Shot-to-shot noise cancellation for parametric oscillators
Martynas Skrabulis, Martin Colombano Sosa, Nicola Carlon Zambon +4
Powerful approaches to squeeze the motional state of a harmonic oscillator rely on the stepwise modulation of its resonance frequency. Such protocols can be limited by forces that…

Nanomechanical sensor resolving impulsive forces below its zero-point fluctuations
Martynas Skrabulis, Martin Colombano Sosa, Nicola Carlon Zambon +4
The sensitivity of a mechanical transducer is ultimately limited by its inherent quantum fluctuations. Here, we use an optically levitated nanoparticle to measure impulsive forces…

Trap-to-trap free falls with an optically levitated nanoparticle
M. Luisa Mattana, Nicola Carlon Zambon, Massimiliano Rossi +4
We perform free-fall experiments with a charge-neutral, optically levitated nanoparticle. This is achieved using an optical tweezer that can be rapidly toggled on and off and verti…
