Polarizability and magnetoplasmonic properties of magnetic general nanoellipsoids [PDF]
An approach to compute the polarizability tensor of magnetic nanoparticles having general ellipsoidal shape is presented. We find a surprisingly excellent quantitative agreement between calculated and experimental magneto-optical spectra measured in the ...

Chiral nano‐inorganics, free of organic chiral ligands, provide a novel platform to direct symmetry breaking in molecular systems, through inorganic‐to‐organic chirality transfer via enantiospecific inorganic–organic interactions, circularly polarized light, and electron spin‐driven enantiopreferential reactions governed by chiral‐induced spin ...

Pre‐magnetized TmIG/Pt achieves volatile circular dichroism (CD) control via current‐induced temperature gradients, without needing a magnetic field, particularly in the UV range due to the Laporte selection switch of the O(2p)→Fe(3d) and O(2p)→Tm(5d) optical transitions through Tm(4f)‐O(2p) interaction.

Plasmonic crystals for ultrafast nanophotonics: Optical switching of surface plasmon polaritons
We demonstrate that the dispersion of surface plasmon polaritons in a periodically perforated gold film can be efficiently manipulated by femtosecond laser pulses with the wavelengths far from the intrinsic resonances of gold. Using a time- and frequency-

Plasmon-Interband Coupling in Nickel Nanoantennas [PDF]
Plasmonic excitations are usually attributed to the free electron response at visible frequencies in the classic plasmonic metals Au and Ag. However, the vast majority of metals exhibit spectrally localized interband transitions or broad interband ...

Optical Nanolinks With Yagi–Uda‐Loop and Dipole Antennas Fed by Gaussian Beam
This work presents a theoretical comparative analysis of wireless optical nanolinks with different cylindrical plasmonic nanoantennas fed by a Gaussian beam. The nanolinks considered are Yagi–Uda‐loop/dipole, Yagi–Uda/dipole and dipole/dipole, where the operating wavelength is λ = 1153 nm.

We report on strong enhancement of mid-infrared second harmonic generation (SHG) from SiC nanopillars due to the resonant excitation of localized surface phonon-polaritons within the Reststrahlen band.

Magneto-Optical Activity in High Index Dielectric Nanoantennas [PDF]
The magneto-optical activity, namely the polarization conversion capabilities of high- index, non-absorbing, core-shell dielectric nanospheres is theoretically analyzed.

Magnetoplasmon resonances in nanoparticles
Nanoparticle plasmon resonances can be controlled using external magnetic fields or internal magnetization. The modified resonance condition is complicated, however, by the induced anisotropy of the dielectric response. Working within the electrostatic regime, we formulate a simple eigenvalue problem for the magnetoplasmon resonances.
