Quantum paramagnetism and magnetization plateaus in a kagome-honeycomb Heisenberg antiferromagnet

Meghadeepa Adhikary, Arnaud Ralko, Brijesh Kumar

A spin-1/2 Heisenberg model on honeycomb lattice is investigated by doing triplon analysis and quantum Monte Carlo calculations. This model, inspired by Cu${}_2$(pymca)${}_3$(ClO${}_4$),…
