In this project Professor Mele will study the electronic and                    structural properties of conjugated polymers and other condensed                matter systems in reduced dimensions.  They will emphasize the                  importance of commensurability effects for the physical                         properties of polymers.  Although these effects are generally                   recognized to be quite weak in conventional conducting polymers,                Dr. Mele feels that these effects may dominate the physics of the               polyanilines (and other similar "doped" structures).  Also                      studied will be the appearance of a "topological" phase in the                  adiabadic evolution of a general class of quantum (and classical)               systems.  Situations in which this topological phase plays a                    demonstrable role in the physics of the coupled electronic phonon               systems, which appear in various condensed matter contexts, will                be sought.
