Interaction-enhanced nesting in spin-fermion and Fermi-Hubbard models
The spin-fermion (SF) model postulates that the dominant coupling between low-energy fermions in near critical metals is mediated by collective spin fluctuations (paramagnons) peaked at the Néel wave vector, Q_{N}, connecting hot spots on opposite sides of the Fermi surface. It has been argued that...
