  Transport and Anderson localization in disordered two-dimensional photonic lattices : Abstract : Nature
Anderson's work dates back to 1958, yet strong localization has never been observed in atomic crystals, because localization occurs only if the potential (the periodic lattice and the fluctuations superimposed on it) is time-independent.
localization effects were experimentally demonstrated, traditionally by studying the transmission properties of randomly distributed optical scatterers (typically suspensions or powders of dielectric materials).
As Anderson localization is a universal phenomenon, the ideas presented here could also be implemented in other systems (for example, matter waves), thereby making it feasible to explore experimentally long-sought fundamental concepts, and bringing up a variety of intriguing questions related to the interplay between disorder and nonlinearity.

 Speakers' Bios
Deborah Anderson is a researcher in the Dept. of Linguistics at UC Berkeley and runs the UC Berkeley Script Encoding Initiative (and its NEH-sponsored sibling, the Universal Scripts Project).
During this time she has led the localization of a number of software products with simultaneous shipment of up to 17 language versions.
Now his mission is to address the needs of Internationalization and Localization within the W3C, applying different W3C technologies like RDF and XML for purposes of Internationalization and Localization, and introducing the merit of these technologies to a broad Internationalization and Localization community.

 Anderson Localization: Introduction of disorder
Once it is understood that in special bands of energy electrons may propagate through an infinite crystal, it is natural to inquire as to what happens in a more realistic situation when there is disorder in the crystal, for instance when the spacing between the atoms is slightly irregular with small, random perturbations.
Phil Anderson won the Nobel prize in 1977 for his investigations into this very issue.
In this sum in perfect crystals, at those energies in the allowed bands, there is enough constructive interference in the forward direction to allow the propagation to continue.

 Tuning the conductance of single walled carbon nanotubes by ion irradiation in the Anderson localization regime
Simulations demonstrate that mainly di-vacancies contribute to the resistance increase induced by irradiation.
By comparing experiments and theory, we conclude that 1 out of 4 Ar+ ions creates one di-vacancy and that a 0.03% of di-vacancies produces an increase of three orders of magnitude in the resistance of a 400 nm SWNT length.
The theoretical calculations also predict a linear dependence of the localization length with the distance between di-vancies, in good agreement again with the experiments.

I tag this for my fellow Edmontonians who may also find the RSS feed useful.
I hadn’t been to the site in a while but was happy to find some local content.
The name is a bit scary, but for those angling for info about someone, I guess you now have a place to start.
