Cell Reproduction in a Dark Optical Trap
Ariel Hertz, Gabriel Dias, Carlos L. R. Fragoso +3
Optical tweezers are a versatile tool in the domain of cytology, enabling trapping and manipulation of individual cells. However, the incidence of laser light causes photodamage to…
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…
Time-dependent accelerated Unruh-DeWitt detector without event horizon
F. Sobrero, M. S. Soares, T. Guerreiro +1
We investigate unitarily inequivalent representations of the algebra of operators in quantum field theory in the cases where there is a Fock representation of the commutation relat…
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…
All electrical cooling of an optically levitated nanoparticle
Oscar Kremer, Igor Califrer, Daniel Tandeitnik +3
We implement an all electrical controller for 3D feedback cooling of an optically levitated nanoparticle capable of reaching sub-Kelvin temperatures for the center of mass motion.…
Generation of classical non-Gaussian distributions by squeezing a thermal state into non-linear motion of levitated optomechanics
Rafael Muffato, Tiberius Georgescu, Jack Homans +6
We report on an experiment achieving the dynamical generation of non-Gaussian states of motion of a levitated optomechanical system. We access intrinsic Duffing-like nonlinearities…
Perturbative nonlinear feedback forces for optical levitation experiments
Oscar Kremer, Daniel Tandeitnik, Rafael Mufato +6
Feedback control can be used to generate well-determined nonlinear effective potentials in an optical trap, a goal whose applications may range from non-equilibrium thermodynamics…
