A resistor model for quantum criticality: quasi one-dimensional organic   conductors
  We investigate the metallic transport in the organic superconductor (TMTSF)2PF6 under pressure within the framework of the spin density wave theory in the proximity of a Peierls quantum critical point (QCP). We use a simple transport model of hot and cold regions around the Fermi surface, driven by the proximity to the QCP in order to provide a template to fit the experimental results. Successful agreement with the data comforts the interpretation of extended criticality around the antiferromagnetic QCP in the normal phase of quasi one-dimensional organic superconductors.
