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…
