Position measurement of a levitated particle with vectorial light
Daniel Tandeitnik, Lucas Bianchi, Sebastian Gutierrez-Bernal +3
We develop a fully vectorial, semiclassical scattering formalism for optically levitated dipolar scatterers, expressed within the angular spectrum representation and applicable to…

Heterodyne position detection of an optomechanical system
Daniel Tandeitnik, Gabriel Dias, Thiago Guerreiro
We report a heterodyne detection scheme for position readout of an optomechanical system, in particular an optically levitated particle, implemented via digital In-phase and Quadra…

All-optical saddle trap as a platform for mesoscopic quantum experiments
Pedro V. Paraguassú, Luca Abrahão, Daniel Tandeitnik +3
We investigate the quantum dynamics of a levitated nanoparticle in a structured light rotating saddle-like optical potential consisting of a superposition of Gaussian and Laguerre-…
