Search for the Anderson transition in ruby

Paul E. Jessop, A. Szabó

Published Jul 1, 1982• 7 citations

Abstract

A new diagnostic to detect the occurrence of an Anderson transition, using photon echoes, is proposed and experimentally tested for the ${R}_{1}$ line in ruby. A search for mobility edges in samples up to 0.1 wt.% ${\mathrm{Cr}}_{2}$${\mathrm{O}}_{3}$ concentration was unsuccessful.

When the ${R}_{1}$ line in ruby is swept with a tunable laser from the center to the wings, the ratio of trap emission to ${R}_{1}$ emission remains constant up to a point in the line where it suddenly drops to a lower constant value out to the wings. We suggest that this break corresponds to mobility edges separating delocalized states in the central region from "localized" states beyond this break.When the ${R}_{1}$ line in ruby is swept with a tunable laser from the center to the wings, the ratio of trap emission to ${R}_{1}$ emission remains constant up to a point in the line where it suddenly drops to a lower constant value out to the wings.
