The plasmonic response of a metal nanoparticle in the presence of surrounding gain
elements is studied, using a space and time-dependent model, which integrates a quantum …

A spaser is a nanoplasmonic counterpart of a laser, with photons replaced by surface
plasmon polaritons and a resonant cavity replaced by a metallic nanostructure supporting …

Metamaterials (MMs) are artificial media tailoring the propagation of light by a design of a
unit cell (meta-atom, MA). There is the evident inclination in favor of numerical methods in …

We experimentally demonstrate the active control of a plasmonic metamaterial operating in
the quantum regime. A two-dimensional metamaterial consisting of unit cells made from gold …

We study theoretically the emission and lasing properties of a single nanoshell spaser
nanoparticle with an active core and a plasmonic metal shell. Using time-dependent …

We study numerically the effect of mode mixing and direct dipole-dipole interactions
between gain molecules on spasing in small composite nanoparticles with a metallic core …

In this paper, by finite-difference-time-domain (FDTD) simulation, we numerically
demonstrate a plasmon-induced transparency (PIT) effect based on a carbon nanotubes …

We study theoretically and numerically spasing conditions and optical dynamics of a
composite hyperbolic metamaterial interacting with gain molecules. By combining Maxwell …

The plasmonic structures exhibiting narrowband resonances (NBRs) are of great interest for
various applications. We propose to use hysteresis behavior in a 1D system of nonlinear …

Single-walled carbon nanotubes (SWCNTs) are nearly ideal one-dimensional systems with
potential applications in a wide range of fields. The rich physics of SWCNTs arise from the …
