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…
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…
