Luttinger liquid

== English == === Etymology === Reformulated by J. M. Luttinger, based on earlier work by Tomonaga. === Noun === Luttinger liquid (plural Luttinger liquids) (physics) A theoretical model describing interacting electrons (or other fermions) in a one-dimensional conductor (e.g. quantum wires such as carbon nanotubes). Such a model is necessary because the commonly-used Fermi liquid model breaks down for one dimension. Synonym: Tomonaga-Luttinger liquid
