Magnon, doublon and quarton excitations in 2D S=1/2 trimerized Heisenberg models

Yue-Yue Chang, Jun-Qing Cheng, Hui Shao +2

We investigate the magnetic excitations of the trimerized Heisenberg models with intra-trimer interaction $J_1$ and inter-trimer interaction $J_2$ on four different two-dimensional…
