Extending vacuum trapping to absorbing objects with hybrid Paul-optical traps

Gerard Planes Conangla, Raúl A. Rica Alarcón, Romain Quidant

The levitation of condensed matter in vacuum allows the study of its physical properties under extreme isolation from the environment. It also offers a venue to investigate quantum…

Overdamped dynamics of a Brownian particle levitated in a Paul trap

Gerard P. Conangla, Dwight Nwaigwe, Jan Wehr +1

We study the dynamics of the center of mass of a Brownian particle levitated in a Paul trap. We focus on the overdamped regime in the context of levitodynamics, comparing theory wi…

Sensing with the harmonic oscillator

Gerard P. Conangla

A system obeying the harmonic oscillator equation of motion can be used as a force or proper acceleration sensor. In this short review we derive analytical expressions for the sens…

Optimal Feedback Cooling of a Charged Levitated Nanoparticle with Adaptive Control

Gerard P. Conangla, Francesco Ricci, Marc T. Cuairan +3

We use an optimal control protocol to cool one mode of the center of mass motion of an optically levitated nanoparticle. The feedback technique relies on exerting a Coulomb force o…

Accurate mass measurement of a levitated nanomechanical resonator for precision force sensing

Francesco Ricci, Marc T. Cuairan, Gerard P. Conangla +2

Nanomechanical resonators are widely operated as force and mass sensors with sensitivities in the zepto-Newton and yocto-gram regime, respectively. Their accuracy, however, is usua…

Motion control and optical interrogation of a levitating single NV in vacuum

G. P. Conangla, A. W. Schell, R. A. Rica +1

Levitation optomechanics exploits the unique mechanical properties of trapped nano-objects in vacuum in order to address some of the limitations of clamped nanomechanical resonator…
