【 摘 要 】

We study numerically a bosonic analog of the Kitaev honeycomb model, which is a minimal model for 4d4/5d4 quantum magnets with honeycomb lattice geometry. We construct its phase diagram by a combination of Landau theory analysis and quantum Monte Carlo simulations. In particular, we show that the phase boundaries between the paramagnetic state and magnetically ordered states are generically fluctuation-induced first-order phase transitions. Our results are potentially applicable to Ru4+- and Ir5+-based honeycomb magnets.
