Saddle point singularity and optical phase transition in bilayer hyperbolic metamaterials
Vitaliy N. Pustovit, David E. Zelmon, Kurt G. Eyink +1
We study theoretically and numerically high density of states for hyperbolic bilayered metamaterials (HMM). It reveals that density response of HMM is reminiscent of Fermi electron…
Surface plasmon amplification by stimulated emission of radiation in hyperbolic metamaterials
Vitaliy N. Pustovit, Augustine M. Urbas, David E. Zelmon
We study theoretically and numerically spasing conditions and optical dynamics of a composite hyperbolic metamaterial interacting with gain molecules. By combining Maxwell-Bloch eq…
Coulomb and quenching effects in small nanoparticle-based spasers
Vitaliy N. Pustovit, Augustine M. Urbas, Arkadi Chipouline +1
We study numerically the effect of mode mixing and direct dipole-dipole interactions between gain molecules on spasing in a small composite nanoparticles with a metallic core and a…
Cooperative amplification of energy transfer in plasmonic systems
Vitaliy N. Pustovit, Augustine M. Urbas, Tigran V. Shahbazyan
We study cooperative effects in energy transfer (ET) from an ensemble of donors to an acceptor near a plasmonic nanostructure. We demonstrate that in cooperative regime ET takes pl…
Fluorescence quenching near small metal nanoparticles
Vitaliy N. Pustovit, Tigran V. Shahbazyan
We develop a microscopic model for fluorescence of a molecule (or semiconductor quantum dot) near a small metal nanoparticle. When a molecule is situated close to metal surface, it…
Resonance energy transfer near metal nanostructures mediated by surface plasmons
Vitaliy N. Pustovit, Tigran V. Shahbazyan
We develop a unified theory of plasmon-assisted resonance energy transfer (RET) between molecules near a metal nanostructure that maintains energy balance between transfer, dissipa…
