Title: Functional Complexity in Soft Electronic Matter

A substantial change is presently taking place in experimental and theoretical approaches to large classes of "strongly correlated" materials. The change reflects growing evidence that multmore »iscale complexity (in space and time) is frequently both intrinsic and functional, and further, that intimate relationships between hierarchies of functional scales consitute essential "Systems" or "Networks." This complexity provides qualitatively new avenues for predictive design of technological materaisl, including instrically nanoscale structures. In the search for underpinning concepts and principles, the prevalence of local constraints and coexisting short- and long-range forces have become apparent as keys to some major class of materaisl with emergent "landscapes" of spatio-temporal patterns and associated glassy dynamics and statistics. This talk reviews our recent work in these directions in the context of elastically-driven textures in (a) directionally-bonded electronic materials, including superonducting, magnetoresistant, and ferroelectric oxides; and (b) bubble opening patterns in DNA. Underscored is the importance of suites of experimental probes being applied to establish the networks of functional scales: microscopic to mesoscopic to macroscopic. Recent advances in angle-resolved photoemission and inelastic neutron scattering experimental techniques are particularly valuable in this regard.« less
