Academic Interests and Plans
The principal focus of my research for the last few years has been the detailed study and characterization of spin systems, both ordered and disordered, that do not develop spin crystalline ground-states. What are the key ingredients necessary to develop a short-range periodic spin system that displays glassiness? What are the similarities/differences between glasses with and without intrinsic disorder? How similar/different are periodic glasses with short-range vs. long-range interactions? How does the introduction of quantum fluctuations affect the behavior of a system with an extensive classical degeneracy? The theoretical challenge is to identify and characterize a minimalist model for glassiness, analogous to the Ising model for second-order phase transitions. It is anticipated that the detailed study of intrinsically non-random glasses will lead to insights in other areas, possibly including content-addressable data storage and alternative optimization algorithms.
I try to maintain a spectrum of projects including abstract theoretical studies and phenomenological approaches to novel materials. Three distinct themes of my current research program are nonequilibrium quantum dynamics, novel magnetic order, and ferroelectric studies.
