Conventional metals have been very successfully described by the Fermi‐liquid theory, but researchers are now studying a variety of more exotic materials for which other approaches might be more appropriate. Among the alternatives is a model of interacting electrons in one dimension. The model is known as the Tomonaga‐Luttinger liquid theory, after Joaquin Luttinger, who formulated it in the 1960s, and Sin‐itiro Tbmonaga, who did influential one‐dimensional studies in the 1950s. It is frequently called simply a Luttinger liquid.
