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…
