Squeezing diamond from fullerenes

Fullerenes generated from porous structures.

A class of macromolecules based on the architecture of the well-known fullerenes is theoretically investigated. The building blocks used to geometrically construct these molecules are the two dimensional structures: porous graphene and biphenylene-carbon. Density functional-based tight binding methods as well as reactive molecular dynamics methods are applied to study the electronic and structu...

Phonon-induced spin-spin interactions in diamond nanostructures: application to spin squeezing.

We propose and analyze a novel mechanism for long-range spin-spin interactions in diamond nanostructures. The interactions between electronic spins, associated with nitrogen-vacancy centers in diamond, are mediated by their coupling via strain to the vibrational mode of a diamond mechanical nanoresonator. This coupling results in phonon-mediated effective spin-spin interactions that can be used...

Anisotropic hot electron emission from fullerenes.

Photoelectron spectra for fullerenes C(60) and C(70) ionized using 800 nm laser pulses with pulse durations from 120 to 1000 fs show thermal electron kinetic energy distributions but they also exhibit angular anisotropy with respect to the laser light polarization. The effective temperature of electrons, measured along the laser polarization direction, is significantly higher than in the perpen...

Squeezing more juice from solar mirrors

Anyone who has wandered around the ANU campus would have noticed a variety of weird and wonderful mirrored arrays. The most obvious, of course, is the imposingly large Big Dish standing on the shores of Sullivan’s Creek. Its massive 400 m paraboloidal mirror is a Canberra icon (and is currently featured on the cover of the local phone book). Just up the hill is a smaller mirrored dish, sometime...
