DFG Reserch Unit FOR1700: "Atomic wires"

Metallic nanowires on the atomic scale: Electronic and vibrational coupling in real world systems

Ideal one-dimensional (1D) electronic systems have peculiar properties, such as quantization of conductance, charge-density waves (CDWs), and Luttinger liquid behavior, a variety of instabilities with a wealth of associated phase transitions. These are due to their reduced dimensionality and the concomitant high electronic correlations. The central topic of this delocalized Research Unit is the exploration and identification of physical scenarios with one-dimensional properties under explicit consideration of 2D and 3D coupling, their control and their manipulation. In order to explore this field with its great variety of physical phenomena successfully and in reasonable depth, a close collaboration between experimental and theoretical groups is envisaged as well as the combination of various experimental methods.
