I. Glasses with long range forces; II. Nano-structured solar cells

Gergely T. Zimanyi (UC Davis)

I. In the first half of the talk, recent work on glassy systems with long range forces will be discussed.

(i) In Dislocations systems the dynamics is shown to be glassy. This dynamics is characterized in terms of aging, coarsening and freezing. A profound domain formation is reported in systems with dislocation climb. The measured coarsening exponent is in quantitative agreement with experimental data on diblock copolymers.

(ii) In Coulomb Glass systems the existence of a phase transition is studied. Also, the Density of States exponent is determined and its relation to the Efros-Shklovski prediction analyzed.

(iii) In Spin Glasses with power law interactions, a strong bound is reported on the droplet stiffness exponent.

II. In the second half of the talk, recent developments will be summarized in the emerging field of nano-structured solar cells.

(i) The experimental situation will be summarized, starting with Klimov’s 2004 discovery of multiple electron generation in nanodots, up to our present understanding.

(ii) The theoretical situation will be summarized, with emphasis on the main theoretical challenges, including various exciton decay channels and surface effects.
