Gain-controlled directional scattering in core-shell nanoparticles mediated by magnetic toroidal dipoles

Tiago J. Arruda

Toroidal dipole moments arise from poloidal current distributions and form a distinct class of electromagnetic excitations with unique near-field characteristics. Using Lorenz-Mie…

Electric and magnetic toroidal dipole excitations in core-shell spheres

Tiago José Arruda

Toroidal dipole moments, which consist of enclosed circulating currents aligned along paths within a torus shape, can be experimentally achieved in metamaterials using various geom…

Controlling photon bunching and antibunching of two quantum emitters near a core-shell sphere

Tiago J. Arruda, Romain Bachelard, John Weiner +2

The collective spontaneous emission of two point-dipole emitters near a plasmonic core-shell nanosphere is theoretically investigated. Based on the expansion of mode functions in v…

Controlling optical memory effects in disordered media with coated metamaterials

Tiago J. Arruda, Alexandre S. Martinez, Felipe A. Pinheiro

Most applications of memory effects in disordered optical media, such as the tilt-tilt and shift-shift spatial correlations, have focused on imaging through and inside biological t…

Photon-antibunching in the fluorescence of statistical ensembles of emitters at an optical nanofiber-tip

Elmer Suarez, David Auwärter, Tiago J. Arruda +4

This proposal investigates the photon-statistics of light emitted by a statistical ensemble of cold atoms excited by the near-field of an optical nanofiber tip. Dipole-dipole inter…

Electromagnetic energy within coated spheres containing dispersive metamaterials

Tiago J. Arruda, Felipe A. Pinheiro, Alexandre S. Martinez

An exact expression is derived for the time-averaged electromagnetic energy within a magneto-dielectric coated sphere, which is irradiated by a plane and time-harmonic electromagne…
