Nanowires and nanotubes, being elongated nanometer-scale crystalline forms of various materials, offer many opportunities to improve the fundamental understanding of materials and processes, to explore physics in new regimes, and to discover new phenomena. Our group is particularly interested in many-body effects and in the consequences of small size or low dimensionality for phase transitions. In the recent past we have worked extensively with single-walled carbon nanotubes, doing transport measurements at low temperatures, to study one-dimensional (1D) quantum dots, metallic and semiconducting quantum wires, Kondo resonances, charge pumping, and excitations of the correlated 1D electron system (the Luttinger liquid). We are currently focused on nanostructures of strongly correlated materials and on the many-atom system of an adsorbed monolayer on the cylindrical surface of a single-walled carbon nanotube.
