Session D40 - Poster Session I.
POSTER session, Monday afternoon, March 12
Exhibit Hall, Washington State Convention Center
Motivated in part by the suggestion that high T_c superconductivity via the BCS mechanism may relate to branched domain structures, we have computed spectral and dynamical properties of a tight-binding electron in several types of random dendrites. We form a structure ensemble and compute dynamical properties by renormalization. Structures include random-alloy Bethe lattices, Vicsek-related random trees, and other related structures. Properties of interest are the densities of states and Kubo-Greenwood conductance at the Fermi level, as well as related vibrational properties.
