Design of a mode converter for efficient light-atom coupling in free space

In this article, we describe how to develop a mode converter that transforms a plane electromagnetic wave into an inward moving dipole wave. The latter one is intended to bring a single atom or ion from its ground state to its excited state by absorption of a single photon wave packet with near-100% efficiency.Comment: RevTex4, 3 figures, revised version, accepted for publication at Appl.

Far infrared transmittance of Sc2@C84 and Er2@C82

We have measured the far infrared transmittance of Sc2@C84 and Er2@C82 at 1.5 K between 30 and 200 cm-1. Both materials are observed to have a large primary absorption feature centered at 95 cm-1 with a width of approximately 50 cm-1, as well as a number of secondary absorption features which are different in the two materials. This is the first study of the far infrared properties of metallofullerenes and may help in the determination of the structural and electronic properties of these materials.

Designing a central bank: Social player, monetary agent, or banking agent?

This paper reviews recent advances on the role of the central bank in the money supply process and its effects on inflation. The literature is presented according to a three-stage process, with the central bank acting first as social player, then as monetary agent, and finally as a combined monetary and banking agent.
