Dielectric matrix and plasmon dispersion in strongly coupled electronic bilayer liquids

Thermal conductivity of strongly coupled Yukawa liquids.

The thermal conductivity of strongly coupled Yukawa liquids, being relevant to dusty plasmas, is calculated from nonequilibrium molecular dynamics simulations. The calculations cover a wide range of plasma coupling (Gamma) and screening (kappa) parameters and yield data which are generally in good agreement with the results of recent independent calculations. An improved analytical formula, rel...

Electronic Properties of Bilayer Graphene Strongly Coupled to Interlayer Stacking and an External Electric Field.

Bilayer graphene (BLG) with a tunable band gap appears interesting as an alternative to graphene for practical applications; thus, its transport properties are being actively pursued. Using density functional theory and perturbation analysis, we investigated, under an external electric field, the electronic properties of BLG in various stackings relevant to recently observed complex structures....

Kadowaki-Woods ratio for strongly coupled Fermi liquids

Integrated plasmon and dielectric waveguides.

We have designed, fabricated and characterized surface plasmon waveguides for near infrared light in the telecommunications spectrum. These waveguides exhibit losses of -1.2dB/microm and can guide light around 0.5 microm bends. Light can also be efficiently coupled between more conventional silicon waveguides and these plasmon waveguides with compact couplers, and we demonstrate that surface pl...

Grating-coupled surface plasmon polaritons and waveguide modes in a silver-dielectric-silver structure.

A silver-dielectric-silver structure that supports both waveguide modes and surface plasmon polaritons is explored. The upper interface between the dielectric and the silver is periodically corrugated to allow coupling of visible photons to both types of mode. Such a metallic microcavity leads to plasmonic and waveguide self-interacting bandgaps at Brillouin zone boundaries. In addition there a...
