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
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.
