This model describes low-energy fermions interacting with their own collective spin fluctuations, which soften at the antiferromagnetic transition. We argue that in 2D, the system has two typical energies - an effective spin-fermion interaction $\\bar g$ and an energy $\\omega_{sf}$ below which the system behaves as a Fermi liquid. The ratio of the two determines the dimensionless coupling constant for spin-fermion interaction $\\lambda^2 \\propto {\\bar g}/\\omega_{sf","authors_text":"Andrey V. Chubukov, Ar. Abanov, J.
