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…

All-optical Saddle Trap
Daniel Tandeitnik, Oscar Kremer, Felipe Almeida +3
The superposition of frequency-shifted Laguerre-Gauss modes can produce a rotating saddle-like intensity profile. When spinning fast enough, the optical forces produced by this str…
