Spin functional renormalization group for dimerized quantum spin systems
Andreas Rückriegel, Jonas Arnold, Raphael Goll +1
We investigate dimerized quantum spin systems using the spin functional renormalization group approach proposed by Krieg and Kopietz [Phys. Rev. B 99, 060403(R) (2019)] which direc…

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 , 060403(R) (2019)] to calculate the magnetization…

Renormalization group for the -theory with long-range interaction and the critical exponent of the Ising model
Raphael Goll, Peter Kopietz
We calculate the critical exponent of the -dimensional Ising model from a simple truncation of the functional renormalization group flow equations for a scalar field theory…
