Spin functional renormalization group for quantum Heisenberg ferromagnets: Magnetization and magnon damping in two dimensions

Raphael Goll, Dmytro Tarasevych, Jan Krieg +1

We use the spin functional renormalization group recently developed by two of us [J. Krieg and P. Kopietz, Phys. Rev. B $99$ , 060403(R) (2019)] to calculate the magnetization…

Renormalization group for the $φ^{4}$ -theory with long-range interaction and the critical exponent $η$ of the Ising model

Raphael Goll, Peter Kopietz

We calculate the critical exponent $η$ of the $D$ -dimensional Ising model from a simple truncation of the functional renormalization group flow equations for a scalar field theory…
