Cooperative bi-exponential decay of dye emission coupled via plasmons

Description: This article demonstrates that the relaxation in the sub-radiant system leads to the population of the sub-radiant states by dephasing the super-radiant Dicke states giving rise to the bi-exponential decay in agreement with the experiments.

New mechanism of plasmons specific for spin-polarized nanoparticles

Description: This article experimentally shows that Co nanoparticles with a single-domain crystal structure support a plasmon resonance at approximately 280 nm with better quality than gold nanoparticle resonance in the visible. The magnetic nature of these nanoparticles suggests a new type of these plasmons.
