Condensed matter physics. A Luttinger liquid, or Tomonaga–Luttinger liquid, is a theoretical model describing interacting electrons (or other fermions) in a one-dimensional conductor (e.g. quantum wires such as carbon nanotubes ). [1] Such a model is necessary as the commonly used Fermi liquid model breaks down for one dimension.
