Quasiparticles and Fermi liquid behaviour in an organic metal

The physical properties of organic metals have generally been described in terms of a highly correlated Luttinger liquid. Using angle-resolved photoelectron spectroscopy, Kiss et al. measure the Fermi surface of (BEDT-TTF)3Br(pBIB), and find that, in contrast to other systems, it can be described as a Fermi liquid.
