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-…
