Recursive algorithm for generating high-temperature expansions for spin systems and the chiral non-linear susceptibility
Andreas Rückriegel, Dmytro Tarasevych, Jan Krieg +1
We show that the high-temperature expansion of the free energy and arbitrary imaginary-time-ordered connected correlation functions of quantum spin systems can be recursively obtai…
Phase diagram of the - quantum Heisenberg model for arbitrary spin
Andreas Rückriegel, Dmytro Tarasevych, Peter Kopietz
We use the spin functional renormalization group to investigate the - quantum Heisenberg model on a square lattice. By incorporating sum rules associated with the fixed l…
Spin functional renormalization group for the quantum Heisenberg model
Dmytro Tarasevych, Andreas Rückriegel, Savio Keupert +2
We use our recently developed functional renormalization group (FRG) approach for quantum spin systems to investigate the phase diagram of the frustrated quantum…
Critical spin dynamics of Heisenberg ferromagnets revisited
Dmytro Tarasevych, Peter Kopietz
We calculate the dynamic structure factor in the paramagnetic regime of quantum Heisenberg ferromagnets for temperatures close to the critical temperatur…
Dissipative spin dynamics in hot quantum paramagnets
Dmytro Tarasevych, Peter Kopietz
We use the functional renormalization approach for quantum spin systems developed by Krieg and Kopietz [Phys. Rev. B , 060403(R) (2019)] to calculate the spin-spin cor…
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…
A rich man's derivation of scaling laws for the Kondo model
Dmytro Tarasevych, Jan Krieg, Peter Kopietz
We show how the one-loop "poor man's scaling" equations for the Kondo model with arbitrary impurity spin can be obtained within the framework of the functional renormalization grou…
