Ground- and excited-state properties of substrate-supported nanowires calculated from first principles

Ideal one-dimensional electronic systems are characterized by unusual and fascinating physical phenomena, including quantization of conductance, charge-density waves, Luttinger liquid behavior, as well as a variety of instabilities associated with a wealth of phase transitions. Real one-dimensional electronic systems are typically realized as substrate supported atomic wires, and thus inevitably coupled in two (2D) or three (3D) dimensions.
