Near-field-driven Radiative Thermal Dynamics in Aperiodic Nanostructures
M. Prado, A. Manjavacas, F. A. Pinheiro +1
Harnessing structural correlations in near-field plasmonic and polaritonic systems hold untapped potential for controlling light-matter interactions at the nanoscale. By tuning the…
Nonergodic extended phase for waves in three dimensions
Marcus Prado, Romain Bachelard, Robin Kaiser +1
Wave transport in complex media is determined by the nature of quasimodes at the microscopic level. In three dimensional disordered media, waves generally undergo a phase transitio…
Gain-assisted optical tweezing of plasmonic and large refractive index microspheres
R. Ali, R. S. Dutra, F. A. Pinheiro +1
We have theoretically investigated optical tweezing of gain-functionalized microspheres using a highly focused single beam in the nonparaxial regime. We employ the Mie-Debye theory…
Purcell effect at metal-insulator transitions
D. Szilard, W. J. M Kort-Kamp, F. S. S. Rosa +2
We investigate the spontaneous emission rate of a two-level quantum emitter next to a composite medium made of randomly distributed metallic inclusions embedded in a dielectric hos…
Anderson localization of light in disordered superlattices containing graphene layers
A. J. Chaves, N. M. R. Peres, F. A. Pinheiro
We theoretically investigate light propagation and Anderson localization in one-dimensional disordered superlattices composed of dielectric stacks with graphene sheets in between.…
Tuning quantum fluctuations with an external magnetic field: Casimir-Polder interaction between an atom and a graphene sheet
T. Cysne, W. J. M. Kort-Kamp, D. Oliver +3
We investigate the dispersive Casimir-Polder interaction between a Rubidium atom and a suspended graphene sheet subjected to an external magnetic field B. We demonstrate that this…
Enhancing Near-Field Heat Transfer in Composite Media: Effects of the Percolation Transition
W. J. M. Kort-Kamp, P. I. Caneda, F. S. S. Rosa +1
We investigate the near-field heat transfer between a semi-infinite medium and a nanoparticle made of composite materials. We show that, in the effective medium approximation, the…
Tuning plasmonic cloaks with an external magnetic field
W. J. M. Kort-Kamp, F. S. S. Rosa, F. A. Pinheiro +1
We propose a mechanism to actively tune the operation of plasmonic cloaks with an external magnetic field by investigating electromagnetic scattering by a dielectric cylinder coate…
Spontaneous emission in the presence of a spherical plasmonic cloak
W. J. M. Kort-Kamp, F. S. S. Rosa, F. A. Pinheiro +1
We investigate the spontaneous emission of a two-level atom placed in the vicinities of a plasmonic cloak composed of a coated sphere. In the dipole approximation, we show that the…
