From Luttinger to Fermi liquids in organic conductors

TL;DR

This paper reviews how interactions influence quasi-one dimensional organic conductors, focusing on Luttinger liquid physics, transport measurements, and the transition to higher-dimensional behavior due to interchain electron hopping.

Contribution

It provides a comprehensive analysis of Luttinger liquid effects and the dimensional crossover in organic conductors, integrating experimental transport data and theoretical insights.

Findings

Transport measurements reveal signatures of Luttinger liquid behavior.

Dimensional crossover occurs due to electron hopping between chains.

Deconfinement transition marks the shift from 1D to higher-dimensional physics.

Abstract

This chapter reviews the effects of interactions in quasi-one dimensional systems, such as the Bechgaard and Fabre salts, and in particular the Luttinger liquid physics. It discusses in details how transport measurements both d.c. and a.c. allow to probe such a physics. It also examine the dimensional crossover and deconfinement transition occurring between the one dimensional case and the higher dimensional one resulting from the hopping of electrons between chains in the quasi-one dimensional structure.
