Spin functional renormalization group for the $J_{1} J_{2} J_{3}$ 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 $J_{1} J_{2} J_{3}$ quantum…

Magnon damping in the zigzag phase of the Kitaev-Heisenberg- $Γ$ model on a honeycomb lattice

R. L. Smit, S. Keupert, O. Tsyplyatyev +3

We calculate magnon dispersions and damping in the Kitaev-Heisenberg model with an off-diagonal exchange $Γ$ and isotropic third-nearest-neighbor interaction $J_{3}$ on a honeycomb l…
